I have done tons of searching over the last couple of months. I thought everything was pretty straight forward. I built a 1G shell over the last few months and last week, I was finally ready to fire it up for the first time. I bought a 3G Eclipse ECU and a patch harness that a guy used with his Evo ECU in his 1G.
I read the stock ROM off of the 3G Eclipse ECU and saved it. Then, I flashed the ECU with Tephra Mods 94170715 Evo ROM. The only adjustments I made to the ROM was the injector scaling settings as I was using FIC 1600's. I went to start the car and wasn't getting any spark. So, I unplugged the patch harness and 3G ECU and plugged in my stock 1G ECU, and the car fired up.
Since then, I have been running the car (still not driving) with RC 550's. Really trying to get to the bottom of this 3G ECU and why I am not getting spark. The stock ROM of the 3G ECU says it is a 2001 Mitsubishi Eclipse ECU, in ECUflash. I was under the impression that all you had to do was flash the ECU with an Evo ROM and you were good and ready to tune.
I am confused about the whole immobilizer thing. I also assumed that the Tephra Mods Evo ROM already had the appropriate adjustments for the immobilizer, but maybe not?
Maybe there are a couple pins that are different between the 3G ECU and Evo ECU (aside from the boost control stuff)?
Is there a specific ROM that I am to use in Tephra Mods V7?
