Evo Viii Ecu

[estoyaqui30]

Has there ever been any thought to run an EVO VIII ECU in a 2G DSM? I see from the manual for ECU+ that the EVO ECU has the same connector configuration. I thought that with that ECU and EcuFlash/ECU+ the car could be tuned nicely and still have all of the OBD II. Here in NJ, OBD II in needed to pass state inspection.

Thanks

Not sure. But if you need OBDII, just get ECU Plus, you don't need an E-PROM to run it. So why would you get an EVO VIII ECU if you can use your 2G ECU and get OBDII?

 

[estoyaqui30]

I was thinking that if a EVO ECU would work, than I would not need a piggyback. Do all of the tuning in EcuFlash. Am I just crazy? With the stock ECU, I keep getting P0300 problems and using a 95 EPROM ECU, the OBD does not work correctly.

How do most people get through State inspections on OBDII? I know that NY is also doing them that way now. I expect that most states will follow.

Thanks

Sorry can't help you with the first part of your post.

But for the second part, see my posts 15 and 16 in this thread:

no problem, I was just curious. I actually have ECU+ in the car presently, along with a '95 ECU and Keydiver chip. I though that it would be nice to be able to manipulate settings IN the ECU...almost like a stand alone and not need a piggyback. I'll go back to my 99 ECU, because the OBDII works correctly in that one. Hey, thanks for the opinions...I appreciate your time.

I've actually heard of this being done, but I can't find the thread on it. The Evo ecu is very similar to the '97-'99 Ecu and only a couple of pins will need to be swapped in your harness to make it work. I believe it only works with '03-'04 Evo ecus and you will need to have the security immobilizer reprogrammed. If I were doing it, I would get a "boomslang" harness for an Evo and swap the pins in it, leaving the cars harness alone.

 

[estoyaqui30]

purevil,

That's pretty good. what is this "boomslang" harness? I will assume that is like what they sell at "machv.com, it goes between the car harness and the ECU. about 6" long with a male on one end and a female on the other. I would assume that the immobilizer can be disabled and that tuning the fuel and timing maps would be modified using EcuFlash software. so I guess that I would need the pinouts for both ECUs.

There's a coupl'a wires that are different on the EVO ECU as compared to the DSM ECUs. There's the intercooler sprayer for the '03 and '04 cars, and the clutch switch for '03-'05. Also, the cam sensor waveform is completely different, so the car probably won't even start. (Though [my] ECU+ could fix that last problem for you.)

Not sure what you'd have to do to make the immobilizer work.

Very interesting idea. Could simplify 2g tuning by leaps and bounds. Could..
Would love to know more about making this work or if anyone knows about any documentation regarding someone who has done this before.

 

[prostreetdsmx1]

just curious if you guys have tried pricing and even finding EVO ecu's? not exactly readily available.

Yeah nearly impossible to acquire for a reasonable amount.

 

[estoyaqui30]

Wow, I didn't realize this post would get so many answers...I expected to get flamed and deleted.

That is a good point, I had not thought about the price or availability of them. However, it would really change 2G tuning. I guess that I will look into it just to see.

New is a pretty crazy price. Here's how it goes used:

I think I picked one up for around $100 last year. Of course, you'd still need something like the ECU+ to fix the cam sensor signal for you. Hmm, /me wonders if there's a business opportunity here...

Glad to have been directed to this thread from my recent post. I am very interested in trying this and I think I will. I was on Openecu.org where someone with I think an EVO5 or EVO6 did the EVO8 ecu swap.

I suppose this is a little late, but the P0300 code is for a random "misfire". You need to have your CAS signal inverted and the code disabled via either a chip or DSMLink.

As per the actual topic, I can confirm that this is possible. There are a number of Evos on DSMLink using the DSM ECU, so the reverse can be done as well. All that's involved is switching a few wires around.

 

[rampridersrider]

I'm not to savy on the ECU swapping abilities, but I have seen Evo's running DSMlink. With that being said, I use EvoScan/SAFC to tune my car. Reads everything just as DSMlink does, just doesn't have the ability to tune the car yet. I figure with the ability to log knock, idc's, etc, that it makes tunning on a 98-99 DSM with just a piggy back MUCH easier and cheaper, considering EvoScan is free to download and my AFC was 80 bucks.

 

[2gGSX]

Without the ability to truly compensate for injectors or adjust timing (to say the least), the EvoScan/SAFC combo is still very limited in comparison to a more powerful system.

However, you are right in that being able to read knock on a 2g finally is wonderful.

 

[turboking15]

rampridersrider, what car do you tune with the evo scan/ safc combo? Did you swap an evo ecu into your gsx or what?

True on that note. The AFC is still very limited to its tuning abilities, but as far as timing goes you can always do it manually via CAS if you have a 6 bolt swap. I do not prefer that option, but it is an option. Right now I am running 18 lbs on a 60 trim with zero knock, and 20 degrees of total timing advance. It runs good for the little amount of time and money I have into it.

I tune my 98 GSX with it. No ECU swap necessary. The Evoscan can supposedly only connect to a 98-99 turbo DSM. The 98-99 DSM's are the only ones with a flash port directly behind the OBD plug. They are apparently pretty close to being able to flash the 98-99 ECU's just like the Evo's. I don't know if you can hook up a 98-99 ECU though and have it work, but I just know it works on my car and my buddies car.

 

[turboking15]

So what would it take for me to do that in my non e prom 95? Can i just swap the ecu's or would i have to get a 98-99 obdII plug as well?

 

[rampridersrider]

I don't have a single clue man. Like I said, I know it works on my car, and will on other 98 and 99's, but thats as much as I know. If you could just swap ecu's then that would be awesome seeing as how they are a dime a dozen. EvoScan is really just a glorified datalogger, but it has the ability to log knock and IDC's just like a 1G. So for me it was a blessing cause I was on a budget and my 60 trim was eating up my stock injectors at only 10 lbs and it desperately needed a tune. For now the car runs good and I ultimately would like to run 24 lbs daily on pump and maybe 26 on race gas. I only see the stock headstuds becomming an issue but ARP's are fairly cheap anyway. I just need more fuel right now. I think that 350 hp isn't out of the question with my goals and I want to do some cams in the future also, maybe even a little spray. It will all be tuned with EvoScan and an AFC. It took me less than 1500 dollars for basically all of my mods including the 6 bolt swap, as they say, DSM=Do S*** Myself

 

[turboking15]

Alright, i know you said there was a flash port behind the obd port. Could you take a picture of your obd port so i can compare it to mine and see what all the difference is? I am attempting to do pretty much the same thing you are ( go fast for cheap ) so if i could get this to work that would be awesome.

Also if anybody else knows the answer to my question a couple posts up please feel free to chime in.
