Evo 8 ECU In 2g Works!!

[jjgrizz73]

Well found out a few things from some of the guys on EvoM:

1) The EDM rom doesnt pick up on the crank/cam sensor malfunction because it simply doesnt have a check for it. So it doesnt contribute to any problems.

2) The EDM obviously already has all the emission checks turned off so the need to disable them(if needed) is not needed like in the USDM roms.

3) I found that when my ignition is in the "off" position my ecu/SAFC (still installed from last setup) remains on until I shut off the fuel. after the engine shuts down the ecu turns off the usual ~5-6sec. after. This leads me to believe that the ecu needs the fuel pump to be hooked into it to properly shut the car off. To save myself some trouble and work I might leave it the way it is and shut it down with the fuel pump since it must be shut off before I exit the car anyways.

Hopefully some of this helps people and goodluck to the ones performing the swap

Anyone here using this along with stock evo injectors? Im trying to figure out exactly what else i need to change to get this to work properly. I know the injector scaling doesn't need to be changed to 450, but im not sure about the maf scaling. That is unless that only applies to the maf and not injector scaling. OH and anyone have any issues trying to get the car to idle?

You guys are not going to believe this......





I emailed Colby from OpenEcu (he's the guy that does most of the development on the EcuFlash program and functionality) back in january of '08. I asked him if he planed on supporting the H8 processor (98,99 2G ECUs) anytime soon. He responded about a week later, telling me that he has been working on making EcuFlash work with the 98/99 2G ECUs, but hasn't quite cracked it yet. I anxiously waited a few months to see if he would come out with a version that would work with my 99 2G ECU. After about 6 months with no other replies, I gave up hope and started looking into the Evo8 ECU swap. As most of you know, I have it working flawlessly now.

A few days ago (almost a full year later), Colby responds telling me that he has cracked the H8 and there is a beta version of EcuFlash that can read and reflash our 98/99 2G ECUs! I'm very pleased that he figured it out...I just wish it would've happened before i did all this evo8 stuff.

So, if you guys want to be patient, it looks like there will be a release version of EcuFlash that can flash some 2G ECUs out soon. Of course, no idea how long "soon" is....

Good to know. Hopefully that comes out soon. Wouldn't have helped me with my unflashable stock 97 ECU, but still it will provide a nice alternative to other tuning options for those owners.

I just bought an '03 Evo VIII ECU for the swap and would love to be able to call on some other DSMers for EcuFlash help once I get comfortable enough with the interface to start manipulating the ECU.

To those that have done the swap already, did you guys use the harness Mach V sells? What about the cable you're using? Since the openport 2.0 cable doesn't work and the tactrix 1.3 is no longer available, are you guys using the EvoScan cable and an older version of EcuFlash? -The EvoScan cable apparently doesn't work with some of the newer versions of EcuFlash...

I have an evoscan cable and can't get the damn thing to connect. I have tried a bunch of different versions of ecuflash, with cracks, and ecu unlocker.....no dice.

Thats awesome. I almost sold all my plastic case ecus on ebay, glad I didn't.
You have any idea which beta version has H8 support? I'd like to start playing with it to get a definition file made for us.

Is this in the 1G in your avatar? Does the car start/run okay on the swapped ECU?

So, the evoscan cable won't even connect to datalog? Seriously WTF is up with tactrix discontinuing the 1.3 cable when their new 2.0 cable is so effin' worthless... and nobody ever gets rid of those old cables either. I wonder how long it'll be before some enterprising individual out there starts counterfieting the old tactrix 1.3 cables.

edit: Nevermind, went back and read the posts you made on the last page. Having the options set for 40 posts per page screws with me sometimes.

Did you install the correct drivers for the usb cable? If your using evoscan does that connect?

Concerning your issue with your codes for crankshaft sensor positioning, i find that very interesting. I have two ROMs I am playing with. One is an from an EDM Evo 8. That ROM throws no codes at all, and works flawlessly. I am also trying to get a USDM Evo 8 ROM with the Tephra Mods to work. When I flash the USDM ROM, I throw similar codes. Haven't figured it out yet. I bet if you use my EDM ROM, your CEL issues will go away.

Just got me car running with the EVO8 ecu i purchased. took me a while to figure out how to disable the immobilizer code but i got it. i have a 96GST and the first thing i had to do was switch plug wires to get the firing order correct, and as soon as it fired up i got P0335 and P0340 for the crankshaft position sensor. so is it safe to assume that the 9927 roms will flash to an ecu that originally had a 9417 rom in it. if so i will give it a try to see if i get the codes again.

clockworktoy, my car has the evo8 injectors in it however i am using a MAFT gen 2 in it so we will see if there will be a need to mess with the injectors, but i don't see why there would be...

also for those that might still be looking for the older 1.3U cables EvoScan OBDII Mitsubishi MUTII DataLogger Scantool still has them in stock but i am not sure for how much longer.

You missed what I meant. The Evoscan cable is not the same as the Tactrix 1.3 cable. Most users who try to flash using the EvoScan cable are unable to do so with the latest versions of EcuFlash.

Discussed in more depth here.

 

[mike96]

funny i just bought one and it works fine for me... installs as an "openport 1.3U" cable and i have already flashed my ecu 4 times with it.

 

[GSXDNA]

as it fired up i got P0335 and P0340 for the crankshaft position sensor...

I have been unable to get a USDM ROM to work with no CELs. I have however been able to get both an EDM and a JDM ROM to work with no CELs.

Sounds like you're running a USDM ROM?

Agreed, USDM does throw the both codes. The EDM rom does not Im running that now. Just have to disable the EGR and boost solenoid that Im throwing codes for. Also looking into making the knock light the CEL like in the USDM roms. Im happy I have my buddy with an evo helping me with some of this ecuflash stuff because I've never used it before.

No, this is on my 2g. I can't start the car because it still has the immobilizer enabled. Evoscan logs, but ecu flash wont connect.

 

[jjgrizz73]

Best bet is to look on EvolutionM for the tactrix 1.3 cable. They pop up quite often but you have to be lucky to catch it as soon as it comes on. You cant order the Tactrix from Evoscan theselves? They have a link to buy it on their website?

Awesome, great to know. Which version of EcuFlash are you using, 1.40 or something older?

Apparently the EvoScan cable is different, check the thread I linked to over on evom.net. Yeah, those old tactrix cables go very quickly.

Has anyone used the new openport 2.0 cable with any success?

 

[mike96]

i am using ecuflash 1.40

flashed my car with the a EDM ROM and so far it seams to run pretty good for the most part. has a bit of a hessitation at cruse, idle is fine and A/F raitos look good all around, although i havent taken it up over 4000 rpm. check engine light came on again i just havent downloaded it yet to see what code popped up.

 

[jjgrizz73]

Im using the evoscan cable and it flashes and works perfectly for me. the only difference may be the 12pt connector only has 1 wire on it instead of the 3 or 4. But for flashing it only uses the one pin which is on there. Believe pin 79 goes to it.

 

[clockworktoy]

Im using ecuflash 1.4 with the evoscan cable and have had no problem. But my orginal question was if anyone was if your using stock evo injectors how did you go about doing the maf scaling? Im new to tuning but im a little lost since its the stock injectors but with a bigger maf. I can't get my car to idle at all, and im also trying to figure that out.

 

[jjgrizz73]

Im using a GM Maf with the maft so Im not sure. What maf are you using now with the evo ecu the 2g maf?

 

[clockworktoy]

Im using a GM Maf with the maft so Im not sure. What maf are you using now with the evo ecu the 2g maf?

Yep stock 2g maf with stock injectors. I have some evo injectors that i would like to use but im still trying to figure out how to do this.

 

[jjgrizz73]

If you have the stock injectors in now (450cc) did you rescale the injector sizing and latencys for them. You may just not be getting enough fuel. If so stick in the 560 evo injectors with the stock values and see if it works better.

 

[delta448]

Cool, glad to see the EvoScan cable is working well for everyone, I'll be purchasing that one soon then.

clockworktoy, I think all you need to do is rescale the MAF. The evo injectors shouldn't be any issue as long as you left the deadtime/latencies etc alone at the stock evo values.

no dont raise the maf scalings --- i was referring to injector scaling only... for maf size i have 257.7 i attached my maf scalings for u to view... -- im using 450 cc blue tops from a 1g and i use 424 injector scaling -- u may need to raise or lower depending on ## trims

Yes but right now hes having idling problems with the stock 450cc injectors, thats why I mentioned to just put the stock evo injectors in so the values will already be set. Atleast thats what I got out of his post...

 

[clockworktoy]

I rescaled the injector sizing, and the maf scaling as the OP stated. I didn't touch the latency at all.
