help! I was out changing maps on my car and in the middle of a reflash it said "ecu comms" and now it wont uninstall or anything. This is my only car.

HELP

yikes, im hearing things like this more and more frequently. happened to me twice. second time couldn't even start car. gonna have to send it to cobb. should only be a week or so, theyre customer service is great.

I'm 45 min from home
F***

OH and I have e85 in the tank as well.

:wallbash::wallbash::wallbash::wallbash::wallbash::wallbash::wallbash::wallbash:

A week or so - yeah I don't think so.

Does the car run?

Happened to me a few days ago. Thank god my X could still start up but the AP was useless afterward and I had to send it in.

I had this problem and just plugged it back in and made sure everything was snug and it worked.

A week or so - yeah I don't think so.

I hope not. :/

This is all a sign I need to sell my car. Yep.

Car doesn't run tried. Just had it towed to my house. I tried the "snug" thing and nothing. :(

lol its a 2010.. you probably dont even have it broke in yet.. just make sure its plugged in snug.. try blowing the connecters to make sure there clean.. i get cannot connect zall the time then retry and it works.

Haha I have 12 k miles on it and have had a
ap 9k of it.

I put my AP on about 1,000 miles ago.. im sitting at like 2800 miles on the car. any news on you car man? You find a way home? Id hate for this shit to happen to me.. im stationed in Hawaii and hardly know anyone lol.. id be fed.

I got it towed back to my house. Funny thing.....Mitsubishi offers free roadside assistance....BUT they charged me 100 bucks to tow it 5 miles from the dealer....it would have been free if it would have gone to the dealer. ha. awesome right. I got home like 10 min ago and now my Mac won't turn on and I'm on my phone. I hope I can get it fixed asap because this is my only car right now. :(

I feel you bro.. I hope it works out.. I would of had it towed to the dealership then had someone else tow it home haha :P Keep us posted.

Yea, well I work 7-7 most days so yea. ha. I'll keep ya updated. arrgh.

yeah, it seems the cobb ap has connection issues, sometimes it takes me 10-15 times on re-connecting it to get my cpu to finally read it. Maybe because it is hot? is the only answer I have came up with. My only negative thing with the AP so far.

I guess rule of thumb is to flash the car at home....Hope you get this resolve man

Did u call cobb yet? You'll need to send in your ecu and the ap. Should only be a week for the ecu, but since you have e85 I wouldn't drive the car. Took over a month to get my ap back. But first time I sent in ap got it back in a week. So u might be lucky. Did it say anything about recovery mode?

Now this is very important because there maybe a way to get it to work but you have to be honest here if not you will fuck your shit up. When they problem happened were you flashing and if so did you turn the key or unplug the AP before it was done?

I plugged ap in. Turned key to on. Proceeded to flash map. Didn't move the entire time it was flashing....got to about 70% and then "ecu comms error" came up.

That's my only guess. I had been logging and stuff for 30-45 min before the flash. I'm going to try it again in a minute to just be sure.

EDIT: Tried it again, still nothing.

Defn not going to flash it anywhere but home now. ha.

I'll have to send the ECU as well? I' wasn't planning on even trying drive it with e85 in it. If anything I could drain it but it's almost a full tank. :(

I hope it doesn't take more than a few days. I live about an hour from the Austin location so it shouldn't. Fingers crossed.

K so try and get it to go in to recovery mode. If I can remember right plug and unplug real fast a couple times then let it kick off it will uninstall then you will have to reinstall.

It's in recovery mode right now, but when it goes to load into the car it still says ECU Comms. :(

This unmarries the AP?

The problem with our ECUs is that the software running on the Flash is what flashes the Flash. Chicken and the Egg problem here. If you write a bad chunk to the ROM or erase without writing something back, and then you shut the car off, the ECU isn't running software anymore that can flash your ECU. This is where a bench process comes in. We have to talk to the Flash chip directly and erase the whole thing and start over again.

Be glad that benching an Evo ECU is fairly easy. On a Subaru, you have to solder directly to the board to get access to the flash chip.

I used to write code for embedded systems like this, and one of the first things I would do was design a system without this flaw. Like how bios let you boot to a backup ROM. :)

I want to add that you can't really bench an ECU running with an AP. You need to send it into Cobb and have them fix it or else you end up with an ECU that isn't married to your AP anymore.

^^^ Hopefully they don't take long. I will be contacting them in the a.m. I understand why it won't work and such, but if the ap's are what is causing this.....then they should recall them and replace them with ones that won't.

To their defense, a number of things out of their control could have caused this.
- Battery Voltage dipped too low
- Connectors had a bad connection
- User error of some sort (not that this was your case)

True. Could have been any one of those things, even if I think I didn't, I might have caused it. Who knows.

I'm not knocking on them or anything, shit happens with anything especially technology, it just happened to affect me.

As long as it gets fixed in a timely manner I'll be a happy camper. Though, I am going to sell/trade the x as soon as it's fixed.

It's not really the X's fault... modding any car will result in problems.

Go buy yourself something else and start modding it, we'll see how long you last with that car too.

Why?

Well I was about to do this anyway regarding school, but this just pushed me over the edge.

I know, I know....I'm going to find something that I won't mod. :p

Why not just drive the X stock then? Wanting to save money on a cheaper car? Or buy something faster off the lot??

If you stick the Cobb AP in the freezer for 5 minutes this usually works 99.9% of the time. I know it sounds stupid, but it works. I've had issues with my Evo AP, and my GT-R AP. If the ambient temps are above 80 degrees my AP's only load up about 1/4 of the time. Each time I'd put it in the freezer and after 5 minutes they always work.

I never had to do this with my Subaru one, but now since they switched manufactures of the boards it seems just having it in the car gets it to hot.

lol, that makes sense but it's funny.

Reminds me of this old computer I had in highschool, the harddrive would start fuckin up after awhile but if I just threw it in the fridge for a bit it would work for another hour or two... hahaha.

I know what you mean, I thought the shop that told me was pulling my leg, but then he stuck my AP in the freezer and 5 minutes later it loaded right up.

nlp, did you try this?^

^^ nope. At cobb right now they are fixing it. Took a hour drive but I could get it fixed today! So I left work early. Yay.

Glad it worked out for you (kinda)

So I got the car started tonite. Re-installed stock wastegate, stock inlet filter, and reconnected stock boost control system. ( took the grimspeed off). I'm running a Stage 2 SF 800cc e85 ots map now.....not one I made....so thats why I put those two things back on....BUT....car is running at only 12 psi, its like the stock ebcs is not even working. Help?

Anyone have a Diagram on how the stock ebcs hooks up? Like to the stock ebcontroller and where the hoses go?

Edit: Figured that out. however...found a problem....replaced one of the "t" hoses that goes to the turbo comressor side. (one with the pill in it), with a hose that doesn't have the pill in it. I'm going to put the pill thats supposed to be in that hose in the new hose tommorow.


Would that not being in the hose cause the boost issue? or is the stock ebc shot?

Well, the stock setup has two 2-port solenoids. One Black and one Brown. The Brown is your Fine / Active solenoid and the Black is your Course / Passive solenoid. They both hook up in parallel as a bleed type system. That said, where are you missing a boost pill?

Figured it out. Got it working. yay. haha. Ap works and flashes maps, car runs. WHOOT.
