Hi guys,
We've had our Evo X for about two weeks now. Put on close to 1000 miles already. A lot of it on the dyno. Today's tuning results were very positive. Simply put, the X has proven to be more tune-friendly than even the IX. While it makes a bit less power in stock configurations, it ends up making quite a bit more power when tuned both cars are tuned. All tuning was done with a modified version of our BMW PROcede v2 engine control computer that was re-coded to accept the new Mitsu-specific 36-3 trigger wheel and misc sensors.

In fact, today's results show that a tuned Evo X (with no additional bolt-on parts) makes as much power to the wheels as a tuned Evo IX with a full exhaust (dp+highflow cat+ cat-back). And that's just for starters. I'm sure the X will benefit from exhaust upgrades as well as additional tuning. Right now, peak boost is set to 23psi, tapering down to just 15psi by 7000rpm. There's a little bit still left in there.

All dyno testing was conducted on a Mustang Dyno at Full Function (www.fftec.com). Baseline was 215whp and 240lbft of torque. Basically right in line with what has been reported by others. Of course, this was on a motor with just 200 miles so I suspect it would have picked up some more hp as it broke in. For comparison, stock Evo IXs do a bit better with approx 220whp/235lbft.

But once boost, fuel and timing were adjusted, we saw a repeatable 285-290whp and 290-295lbft of torque. For comparison, Tuned Evo IXs end up making 270-275whp and 280-290lbft of torque on the same dyno. This is on straight 91oct.

These are very good preliminary results. I honestly wasn't expecting the X to do that well with just a first-attempt tune. Here are a few tuning runs from today:

http://i85.photobucket.com/albums/k43/shiv94506/evox285.jpg

Observations:
-The X runs grossly rich under boost. So rich, in fact, that the engine bogs briefly between shifts at WOT. Really annoying.
-Power output is very sensitive to fueling as soon a AFR leans out from the 10-10.5:1 AFR range it usually runs in at full load. And it stays reasonably sensitive to enleanment even into the 12-12.5:1 AFR range. Something that wasn't the case with the 4G63.
-Engine still makes power in the presence of detonation events (which is not good of course). The 4G63 would behave differently by immediately yanking back several degrees of timing and 20-30lbft of torque. Not sure why the ECU in the X isn't as reactive to knock a the older ECUs. One interesting thing I noticed is that the tachometer movement becomes "sticky" when accelerating during audible knock activity. Haven't seen that before.
-Engine tends to detonation at fuel cut. We had to enrich and retard the last 300rpm prior to fuel cut to prevent this from happening.

Post Tune Driving Results:
-Finally feels like an Evo. And it now enjoys to be revved out to 7000rpm.
-Extra power really makes all the fancy drivetrain electronics shine brightly. Feeling the front end of the car immediately 'tuck in' midcorner as soon as the throttle goes down is downright cool.
-Power output is incredibly consistent and smooth, just as the dyno results suggest.

There is really no area of performance that doesn't have the IX beat handily. The X is more comfortable, more drivable, just as straight-line quick with similar mods, far quicker and more adjustable through any kind of corner, etc,. Really, this is an incredible car. Especially in the rain
Next week, we'll do some more tuning as well as test some exhaust and piping upgrades.

Cheers,
Shiv

I need to get that done...

nice more good info.

I seriously hope the TC-SST will be able to with stand the power increase from the re-adjusted tuning so its no longer stupidly rich.

That is crazy power just from a tune!

Wicked!

Welcome, shiv@vishnu (http://www.evoxforums.com/forums/member.php?u=714)!

Can't wait to see how the PROcede for the Evo X turns out...it's looking great so far. Hopefully you can find a way to make it more proactive in pulling timing when the knock sensor detects detonation.

Zomg! I can only hope this means they are going to put out one of their awesome god-powered chips like they did for the IX... *drools*

I just want them to get a hold of an MR and see what it can do before it blows up.

Me too! Either that or I hope Mitsubishi does a better job of tuning it right from the factory. It would suck if it was stuck in some under tuned sate just because of the transmission.

i wonder what would X haters will say now, i don't post much since i am a fan of the car unfortunately i don't owe one myself to actively take part is discussions, IMHO lately i have seen lot of ego issues from VIII and IX owners who simply refuse to accept that there can be a possibility of X being a better car

Its getting a lot better now, most haters have already stfu

^yep, but not all. soon, the haters will be driving x's and acting like they were never part of the hater crowd. fuckin' phonies if you ask me.

^lol, yup.

....All the bandwagoners shall now jump on.

Shiv, why do you think that the X isn't pulling timing when it knocks? This is worrisome to me. Other than the tach needle sticking when the motor knocks, which is strange, great work! Those gains are huge, no doubt the 9 fanboys will be pissed. I love it. The X is such a capable car, it's really starting to amaze me how much power the 4b11 is making. God the wait is killing me; 2 more weeks until mine is here!

Is the PROcede a PnP system? Or is a hard-wired piggy-back unit? Does is come with "canned maps" for instance a full stock setup running Cal 91 piss gas?

Sorry, just not familiar with this ECU tuning system. Is there a link about this product? (price, features, sponsored tuners)

Hi guys,
Just a quick update. Been testing our tuned Evo for a full week now. No knock issues. No codes. No driveability issues. And power is as consistent as it ever could be. Yesterday, we built and installed an exhaust. It consisted of a 3" cat and a 3" cat-back using a single standard Magnaflow muffler. Upon driving, it was a bit too loud for my taste (hey, i've been driving BMWs for the last year!) so we installed the second muffler section. So it looks reasonably stock from the back, with both bumper cut-outs being used. An extra exhaust dropped exhaust velocity in 1/2 which meant that the exhaust stayed twice as long in the muffler which means that sound become considerably quieter. The stock downpipe is still installed.

Just a couple of observations:

-The stock cat is huge. The inlet and outlet isn't 3" but the area inside the cat housing is massive. Which means that it conceivable flow very well. Maybe even better than the 3" cat that we installed. Maybe we will re-install that next and visit the dyno again.
-The factory downpipe doesn't look too miserable. It isn't flattened like that DPs on the VIII and IX since it doesn't have to clear any subframe braces. We'll make a 3" downpipe and head back to see if there is any significant power to be gained.
-The car pops nicely during deccel. Not loudly... but muffled. Real nice. Probably has something to do with the minimum allowable on-time and size (650cc!) of the factory injectors. Wouldn't mistake the exhaust note for an lambo or ferrari but it's certainly nicer than the older VIIIs and XIs with similar exhaust systems. Dual mufflers FTW And now for the new dyno results....

Dyno Details:
Stock X with 3" cat and 3" cat-back
Tuned by a modified BMW PROcede computer
91oct
On the Mustang Dyno at FFTEC.

I'll post up the graphs later tonight but for now, here are the results:

WHP: 297-302whp
Torque: 310-315lbft

This is up considerably from when the car was running the stock exhaust. You can see those results here:

http://forums.evolutionm.net/showthread.php?t=322616

These new results are about as good as the absolute BEST results we've ever got out of a Evo IX running a full catless exhaust (3" dp, 3" test pipe, 3" cat-back). But we're talking about the top 3-5%. Most IXs with full catless exhaust usually fall in the 285-290whp range.

It is much stronger than a similarly modified IX (which would only make 270-275whp/290-300lbft with a 3" cat and 3" catback).

Predictions:
With a just a test-pipe (but leaving the factory DP installed), I suspect this car would make 315-325whp. Which would be about as much as we would get out of a IX running a catless GT3071 turbo kit on the same 91oct gas. But with far more torque

Again, all this is with the factory airbox, filter, IC and IC piping still installed. So there are a few more places that we can squeeze out a bit more power. Fully squeezed, I would not be surprised if we could eventually get 330-340whp on 91oct. That's nearly 400whp on a Dynojet with the stock turbo, on pump gas. Now that is something to be excited about.

Going back next week to test some more bolt-ons and race gas mapping. This new engine is spectacular!

Cheers,
shiv

music to my ears.

What was changed in the tune? My main question is wether the MIVEC for the intake or exhaust was changed any. If not, I can't wait to see how the X does when someone does!

I am going to be working on the intake when my X arrives, but gotta wait till then :(

I'd love to get this on my X when I get it. Does this apply to the MR?

I'd love to get this on my X when I get it. Does this apply to the MR?

I'd think so, seeing how its the same engine, just a different transmission. Damn, this sounds so sick though. I never read up on the Evo IX, but heard about Vishnu's work on the 335i and wow, i'm damn happy they are working on the EVO X ecu

From what I've heard the SST transmission has it's own computer/ecu that has to sync up with the main ecu, so it may not be as easy to apply performance mods to it. However I'm not a big mod guy, so my understanding of the whole thing could be wrong. :o

Dan

just curious, but when Vishnu starts selling their ECU chip for the EVO X, will that void warranty? i heard that it didn't void warranty with the 335, so i'm hoping it doesn't

I think it might void warranty my friend, as the ECU is a key component, i don't think mitsubishi will want to help you fix a dodgy cylinder if they find out you have a revamped ECU.

I-----want-----tuning!!!!

The trouble with trying to answer a question like "Will it void my warranty" is that the answer is never straight forward. If your dealer is looking for a reason to try and void your warranty, then they may find said device and decide to void it. However, if you are working nicely with your service department, your car doesnt look abused, and you dont brag about massive whp gains etc, chances are you will be fine. Regardless, if they do want to void your warranty, remind them that they have to prove that the device they are using to void the warranty is the definite cause of the failure.

That being said, I have never had an issue, except for the time I had a hijack device catch fire and do some damage. Which is why I won't use those devices anyway.

thanks. very good point. I'll make sure that they prove to me that the reflash is the problem. if they do blame it, i guess ill just make them prove it to me by showing me first hand. good advice

Look its a plug and play. if you go to the dealer unplug it and go in stock. get the service done, then go home and plug it back in. the service department will have absolutley no clue that the piggy back system is on it at all. Thus never voiding the warrenty.:godance:

Except if the in-built computer logs the data, like my Dad's Renault does.

Is that log overwriteable?

The car does have a "black box" as so to speak. Its called the Tale of the Tape, and you can delete the events on it. They are basically just snap shots, according the service manual, of instances where the PCM detected issues. So, regular driving doesnt trigger the system, nor does brisk driving. However, if you throw a SES, or get an air bag to deploy, information will be stored.

The PCM also stores data on when any device is connected or disconnected from the CAN bus as well. This is true for everything except the MUT-III/CAN scan tool. These codes are also easy to remove though, if you have the factory NAV package.

Vishnu Evo X acceleration tests

Hi folks,
The Inside Line (Edmunds.com on-line performance magazine) just tested our tuned Evo X. Probably shouldn't reveal all the testing numbers. But it's probably okay to spill the beans on acceleration. I don't have the the atmospheric corrected numbers, but according to memory, the quickest it actually ran was a 12.6@109.9mph. Best trap was just over 111mph. But the launch was weaker so the ET was slower.

Just a few things... launching this car was a problem. The factory ECU not only looks at clutch position but also vehicle speed to determine whether to active the 5000rpm launch limit. So there wasn't any quick and dirty fix at the time of testing. Disconnecting the clutch switch (a la Evo IX) didn't work. So it would bog off the line regardless of how it was driven. As a result, the best 0-60mph it could muster was a 4.7s. Once we defeat the launch nanny, we should be able to knock 0.3-0.4s off of that time and bring 1/4 mile ETA down to 12.2-12.3s range.

Still, as is, our ET and trap speed are still approximately 1sec and 10mph better than the last stock Evo X gsr they tested. So this gives a good idea of what kind of power the car is making with just our PROcede engine computer and 3" exhaust. More info to come but we'll probably just wait for the review to hit the net first. As always, the guys at The Inside Line/Edmunds were great to work with. They take their jobs very seriously. Also tested that same very day was the new v8 M3, 135i, Audi S6, and Mini Clubman. The M3 testing results are already up at (http://www.edmunds.com/insideline/do...pageId=136231). Everything else should follow soon

Regards,
Dustin

^ some good #s there.

Hey guys, can someone help me figure this out... if it's running crazy rich, and you fix that with a computer like above, are you saying the result is a engine that runs leaner.... hence better MPG?

Absolutely.

Its not uncommon to get an after market ECU tune and see a fairly large increase in mileage. Its a bit early yet for the X, but we may get better mileage after we have access to the ECU.

Nice. Yeah I have head of a little MPG increase, in the GTi with tuning but didn't know why/how that happened. Very interesting read. thanks.

75HP!!!!!

thanks guys this makes takes away all my doubts about purchasing the X ive been researching it for about 2 months now trying to decide if i want to spend the money but now im sure i do.... BUT know i dont want to wait for one hahaha

I'm keeping an eye on what Vishnu is doing. When they finish this product I might be interested. I have the 3" exhaust part covered. Just to say though, If a better launch(new clutch maybe would be good) with that set up gets the X already into the near low 12's...that is insane.

A new clutch is not necessarily going to improve launch times significantly. I'd bet that a lot of it has to do with the computer controlling the distribution of power to all the tires.
I've noticed a change, albeit small, in the acceleration profiles between the tarmac, gravel and snow modes on my GSR with the tarmac letting it get on the gas sooner with a bit jerkier movement. The snow and gravel modes were a bit more tapered, for lack of a better word, when it came to acceleration they were smoother and less jerky.
I don't know if there's a way to tinker with these, what I will call launch profiles, but it might take a bit of work in both areas (mechanical and electrical) to get the car do what we all want it so desperately to do.
edit: this car is a real technological marvel unlike any I've ever come across.

A new clutch is not necessarily going to improve launch times significantly.

Not what I meant. You dump these stock clutches more than two times and you are going home with a burnt clutch.

^^ Time will tell but I see what you mean, I too would like to upgrade my stock clutch in time but if I have to wait until it dies naturally then so be it.

Not what I meant. You dump these stock clutches more than two times and you are going home with a burnt clutch.

I hope everyone elses clutch lasts a lot longer than 2 times.. Ive probably dumped it more than 10 times so far.. still feeling ok...

I know I will wear it out if I carry on though so yes I would consider a replacement then after Ive abused it as much as I can. :)

I'll let you know if my SST can handle this. If not, then I and only I will have to change whole SST tranny at $8000, so you don't have to. :godance:

Just bought for my SST all these items and 100cell metal cat.
I'll tune with UniChip, should be around 400HP at crank, but keeping the torque the same with 23lbs. boost.
Will let you know if the SST can handle.
SST limitation is torque, not HP.
