Thanks. Sorry if I came off as a jerk in my last post. That wasn't my intention.

 

did u ever figure this out as im about to use an evo 8 ecu on my setup also..

 

I am also interested in the details of this swap. I would like to put an Evo VIII ecu in my 98 GSX. The rewiring shouldn't be too bad. The only problem would be disabling the immobilizer.

I found this over at www.Aktivematirx.com

"I just had my ecu reflashed with the immobilizer removed. Heres what I did.............

1. order a tactrix cable
2. download ecuflash
3. read your ecu and save hex file
4. e-mail hex file to lucasenglish@yahoo.com and explain situation
5. they will send back a modified hex with immobilizer removed
6. reflash ecu with modified .hex file

They didnt charge me anything but I am going to pay them for a tuned map once I get my car running right."

i completed my dual ecu setup and it works fine- - disabling the immo is very easy.. Wiring is pita but not very hard..
