FINALLY :rock:

Beat me to it :). I'd be more excited if I hadn't been testing the last few weeks :)

So you can basically switch between maps by one of the 4 methods? How do you know which map you're on?

WTG, Tephra! I saw this in beta and I'm glad to see it's finished.

Icon on the HUD. ;)

Icon on the HUD. ;)


How many maps can you swap between?

First off, there is only 1 set of Alt Maps, and you have to choose the selecting method. You can only have 1 selecting method active at a time.

The InterCooler Sprayer light flashes in your dash when the Alt-Maps are active. No we (USDM) don't have InterCooler Sprayers. Yes we (Everybody) have an InterCooler Sprayer light in our dashes.

It's really only 3 ways to swap, because the UDSM uses one of the analog inputs already, which is why Tephra had to find a second method for us.

I guess I should add...

At the moment, only 2008 USDM GSR is out.

The rest are in beta testing.
(Sorry 2010 USDM GSR's... I'm not done testing yet)

So how does this work?
You push X button and you can switch to another map saved on your ECU your just a couple of tables?
How long does it switch for?
What happens if you switch while WOT or is that even possible?
Could it potentially lock the ECU if you do it wrong?

Ok noob moment.........

This is a tune for the Stock evo x??.......if so how do u transfer it to the car??......

*waits to be hated on*

Yes you either change maps from holding down the throttle for a certain amount of time, or hold the cruise button for a certain amount of time or switch or via wired failsafe.

It switches maps for however long until you switch it back. :)

The TephraMOD has been in use for years on the Evo 8/9.

It's all explained in that first post in Tephras thread.

a friends been testing it. im just glad to see it finally released :godance:

Ok noob moment.........

This is a tune for the Stock evo x??.......if so how do u transfer it to the car??......

*waits to be hated on*

the maps contained in the ROM are 100% stock in both the main maps and alt maps. if your car has been tuned you will need to copy over everything into the hex file supplied by tephra in the main map section and then test the alt maps by changing some settings such as boost to make sure the alt maps work.

What happens if you switch while WOT or is that even possible?
Could it potentially lock the ECU if you do it wrong?

You set thresholds for time / load (that you must be under) to switch to alt maps. Since this is intended as a meth failsafe it will always switch "down" to regular maps immediately.

Just like any flash, if you do something wrong there is a possibility of bricking the ECU... but its only a bench away from a fix if you really bork something. The way the XML is included it would be pretty hard to screw up at this point.

So im 100% stock......how do i get the MOD map into the car??.....do i need a device?

the key thing is to remember to use the HEX/ROM supplied by tephra and not your stock. simply adding the xml code does nothing without the modified HEX/ROM file :thumbup:

well as of now there's no point to adding it to the car unless you will be tuning it and/or running dual maps. simply wanting the knock light is a good reason as well.

dual maps........race gas and pump

Hollywood, here is a screen shot of the tables that can be swapped. You must be under Load Threshold in order for the maps to swap. The ADC (meth failsafe) method will always swap back regardless of the load.

The CruiseControl switching and the Gas Pedal switching stay forever until you change it back. Like, if you set up one set of maps for E-85 and the other set for pump gas.

The car must be off for TPS switching. Car can be on or off for CruiseControl switching, but if the car is on, you must be under Load Threshold to switch.

It still sucks you can't have more than 2. It would be nice if there were 3. Reason I say this is one for 91, one for 93, and one for e85 for those wonderful track days.

Heck, I would take 4. :)

I'm not sure what for, but I would figure it out. Econ, E-85, 91, something else.

It also sucks that Tephra took his time to make this for the community right? :duh:

I'm pretty stoked for this. KnockCEL and mild/hot E85 tunes will be on tap.

It's an engine saver for anyone running meth...I wouldn't even consider meth without this kind of map switching.

NLTS is the next big one. If that can be done on the X then that'll be something.

It also sucks that Tephra took his time to make this for the community right? :duh:


:+1: this is only the beginning

Wow this software stuff is over my head lol McGyver car :)
I can just imagine someone getting in one of these cars... You get in, hold the throttle down click the cruise etc "What are you doing?" "Switching to y meth map, duh"
I can't even fathom the hours of sorting through code connecting the dots to make all this work. Kudos to Tephra and the others that beta tested this is pretty cool.

With knowledge and imagination anything is possiable

It also sucks that Tephra took his time to make this for the community right? :duh:


No need for childish comments. I'm grateful that there's someone so talented that they can do something like this for the community. I would do it if I had the knowledge. I'll never be that good. My wish will always remain regardless of your comments.


Thanks tephra.

yeps, BIG thx and all the hardwork tephra has done ! countless hours and research.

tephra, where are you ? aren't you gonna chime in n say hello ? LoL

i'm 1 of the EDM/AUDM testers for tephra. works well but not much time to fully utilise it for now. i find that cruise control works the best for me. easy no hassle just push of a button and within a second, voila i'm in race mode baby.

i'm very sure there will be further developement to come ;)

Are you still able to activate the cruise control for what it was also designed for?

^ yes :)

Thanks all!

I have been updating the EvoM thread.

Mainly because I don't want to have 2 streams of information going on :)

My post was more of a joke so I'm sorry if you found it "childish", I'm not sure how that was "childish" but whatever.

I just found your post could have been worded a bit better. Something like "This is great, I really wish we could have more then just two maps to switch between though" instead of "It still sucks you can't have more than 2"

:D

So glad to see this finally released!!! Great Job Teph!!!

Hey Bryan, can we get this worked out for my next tune? I would like to have a "Special Blend" map (91/100octane) for those fun days! ;)

Wow this is great good job Tephra and anyone that helped you with this.

Cool. No problem by me then.

Map switching is awesome, but only really makes sense/is logical for methanol/failsafe of some sort. That's where it fucking shines. For anything else, be it changing octane, changing to E85, etc, etc, you're generally not needing it OMG RIGHT NOW.

Really? Try driving around on E-85 with a blinking "Get Gas NOW!" light on your dash, no laptop in the car and the nearest E-85 station is 30 miles away.

Knowing that Tephra's mods are installed and you switch to 91 pump by holding your Cruise button down...
---Priceless.

You are the man, Tephra.

e85 is cool however none are around me. I hate filling up as much as I do now I could not imagine this on e85 filling up even more often.

More like every two days...

I go a week between pump visits. But yeah, < 200 miles on a tank does suck sometimes.

My station just lowered E-85 to < $2. :)

Yea i agree, even in Minnesota where E85 is plentiful, sometimes it has been tough to find a station and I have got worried. I usually prefill if i know i might need some. As in fill up when i am not even close to empty.

yes cruise control still works as normal, no need to hold it down just push it once, lights up you can use it to cruise or floor it in race mode.

You can also set the amount of time required to hold the button down before it changes maps. This may help in case someone drives your car and fat fingers the on/off button. :) My car would pretty much die if you did that. (E-85 to 91 map)

The ADC (meth failsafe) method will always swap back regardless of the load.
This is wrong. (continued below)

I added this as well cause it comes into play.

I helped beta test the meth fail safe and i am IN LOVE with it.:wackoff:

Once the ecu pin is grounded AND you are BELOW the load threshold the defined counter begins. once the counter reaches its value alt maps active.

my settings
switch:4
load:100
timer:3000

so if my meth kit give the "ok" by the fail safe wire being grounded and i am below 100 load for 3 seconds my meth tune turns on.

if at any time my failsafe is activated (ground removed) I INSTANTLY switch to my standard pump tune. a ton of fuel is added, timing is pulled and boost drops to safe 93 octane levels. I will remain on my 93 pump tune until my meth kit gives the "ok" again (by turning the ground back on) and i am below 100 load for 3 seconds. this is because if your doing a pull it will switch to the safe map until your off the throttle preventing the maps from toggling back and forth

how fucking cool is that?

<3 ya T!

By Swap back, I meant exactly what your post said. Swapping back to your normal maps. i.e. Swapping away from the Aggressive maps. It will always go back to your normal maps regardless of load. (when it senses the trigger to go back)

Sorry if my post was misleading.

gotcha. i mistook it the 1st time and wanted to make sure people knew how the parameters worked together!

Tephra, you are the MAN!!!!! I just got Aquamist, and this is perfect timing.

This makes the E85 decision so much easier :clap:

(perfect example btw, Golden)

If you were stranded with no E85 in sight, would you go as far as you possibly can to a gas station and then let the car idle for a while until you're damn near empty and THEN fill with 93 (91)?

How finicky would this be for the transition? I've heard of many people bringing tanks of E85 to a tune and bring the car in on 93 (91) with the gas light on and then run the car out of gas on the dyno, then fill it back up with the E85 from the tanks?

I understand that's so that you can tune with what you KNOW is E85, but how about the instance where you're in a pickle and can use Tephra's map switching to go back to 93 octane?

If you're going to run E85, and put yourself in a position where you could potentially be without E85, install a fucking valve in your tank and have the ability to drain it. Just do it right. Vavles are cheap, drilling your tank is cheap, just do it right IMHO.

*PERSONALLY*, I don't find the map switching that useful for E85; I always have a laptop with me. Fuck, I always have multiple laptops with me. And I don't plan to go with E85 and then take the car somewhere where I can't get it.

That being said, if I *DID* go E85, I'd do a valve. That's the best method IMHO.

Just have a barbed hose in your trunk and take one side of the Fuel return line off at the FPR and run the car and it will drain the tank for you. ;)

Much easier then drilling a tank (?!?!) and installing a valve, not to mention you would need to drill and install two (one for each side of the saddle)

- Bryan

Well, that too. But that'd require leaving the pump on and running.

I've drilled and put valves into Camaro tanks before, to no ill effect. But yeah, the barb would be simpler.

Was about to say the same thing...we did this just last weekend to get some E85 into my car. I nearly ran out on the dyno and the nearest station is a bit of a drive from my tuner.

*PERSONALLY*, I don't find the map switching that useful for E85

I plan to have mild and hot tunes on my car. I don't need 32psi and that 'ASC off' nonsense on a leisurely drive.

Pffft. I don't really care about all that. If the light is flashing, you have 1.5 gallons left. Fill it all the way up with 91 that contains no Ethanol. (13 gallons) That puts you at less than 10% Ethanol. How many out there fill up with 93 Octane that has 10% Ethanol in it? It's actually better than straight 91.
So, back to the fill up. Fill her up, start it up. It will start to idle like crap after a few seconds to a minute. Push cruise control button. Done. Yes it's that simple. No you don't need to do any fancy emptying of the tank and stuff.

Now, when you switch back to E-85, empty the tank or run it dry. But this is simple because you can do it on your time, when you control where the gas is.


Hotdog: There are a handful of E-85 gas stations in my town. I live right by one. Sometimes shit happens and you end up on the far side of town without gas because you were late, you had to help a friend, or just because shit happens. We can't plan our lives around tank fulls of gas. Nor am I going to empty my tank on the wrong side of town. I'll fill it up, hit Tephra's magic button, and get the heck out of Dodge.

yeah you don't really need to run the tanks dry... if you do the math you get like E80 or E10 I think from memory...

So going from E-85 to 93 is ok, but not going the other way? Not sure if you guys are saying that.


This need tuning gives me goose bumps. Might be selling my cobb if I can switch that easy. Besides I almost always have a laptop in the car.

i think he means that your 91/93 map can be less agressive so having a bit of E85 in there wont matter too much..

I was saying that you can probably make BOTH maps a little less aggressive, do the math 5L of 93 with 50L of E85 is like E77 :)

I m so going to buy one of these after I get my FP Red and injectors on. :rock:

Yes indeed. A local E85 station had a snafu once and a bunch of the locals (including me) ended up getting around E55-E60 in our tanks.

The fuel trims swung negative obviously and some guys got a CEL for fuel trims. My car ended up running about 1-1.5 AFR richer at WOT and felt sluggish. Knock light never came on and I logged the car and no knock whatsoover. My personal car I tune much more aggressively then others.

That said, I usually recommend guys that switch between maps to run down the pump gas to the light, then fill up with E85, drive around normally (on the E85 map) for about 1/4-1/2 tank then refill and then have fun. Just to be on the safe side.

Great! This comes out 2 weeks after I get rid of my evo. lol Thanks anyway, Tephra. You are the man that makes open source tuning so great and easy in the evo community vs others. I wish great Karma to you.

merci :)

How much for one sent to 27214? PM please

You just download it and send Tephra a paypal donation. Your tuner can do this for you, just have him do it on the dyno and then he can pay tephra the 30 bucks.

First page, use that link and the links are on that page.

Tephra didn't want to have two different places to update links.

It still sucks you can't have more than 2.

Waaaah. 2 > 1.

If you really need 18 maps that are changeable ON THE FLY, just get a standalone.

For the once a year you run racegas, you can upload the map manually.

Tephra also says that it is two maps "for now"...i am guessing there will be a revision to add a 3rd, more than that i doubt.

We just have to wait till Tephra needs a third map. Then we will all get a third map.

how many maps do you guys want?

We want NLTS!!!

I think two is really nice but I guess for some three would be ideal. In my senario I think two is perfect.

how many maps do you guys want?

You should hide some things in the coding like if you leave your blinker on for X amount of time the car goes into limp mode :priceless: I love reading about this stuff its crazy how much can be done now vs 10 years ago. Back then this would have cost you 5 grand minimum.

I hope Tephra makes 5 grand minimum off it. Great work mate!

Yea NLTS should be top of the list next, my donation will be coming when my car gets put back together and tuned tephra :)

Hi,

Tephramods has got me started on the OP 2.0 again...

Lucky Tephra lives on the underside of the planet. Cobb might try to put a hit on him for converting people from AP to open source =)

Or hire him like they did with the Subaru Guru. :)

Does anyone know if there are plans for ALS in Tephramod ?
I guess this is a question to Tephra.

By the way i'm currently testing Tephramod V1. Works great. Although I was wondering what about the DTC's. Can I use definitions for 020 ROM ?

The car is 2008 GSR.

no plans for ALS yet.

if the DTC's "before" values match then you are probably good-to-go :)

Donation on its way :)


What do you mean by "before values match" ? Actually I got P0140 this morning. The mod was flashed to the car yesterday.

in my DTC table name I have P1235 0x384 -> 0xffff

or whatever

make sure the current value is 0x384 - if its not then the DTC is probably wrong.

make sure all 5 match :)

Sure - all clear.

Donation sent :)

The DTCs definitions i have been using since rom 15 have carried over and the values match

Tephra Mod's XML file just inherits your old definitions. So what ever you had before, you should still have plus the new Tephra Tables.

You are right. Thanks for help.

I've uploaded a few more romid's in the last couple of days...

2008 USDM MR
2008 EDM/AUDM GSR

I think I will look at doing 2010 USDM MR next, and then some JDM's :)

I have only modified the most recent ROMID for each year/region/type. So you will have to "upgrade" to this version


How do you mean exactly "upgrade" to this version? I am running 52680017 RomID, what would be required to get this up to 52680122?

well in your case I would flash 52680122 as it is, then tune from there.

52680017 -> 52680020 there were some changes around the fuel delivery, so its best to start fresh and retune.

Most likely you will end up with the same result (tables wise)

Maybe I am misunderstanding something here. The 52680122.hex file, from the first post, only has the rom descriptor and the Tephra mod elements. Are you saying to flash only that hex over my rom? I understood you that I needed to flash the 52680122 stock rom first. Or better yet, if anyone has a howto that would be great.

Nevermind, I got it. Thanks Kracka!
