ecu issues!

[gstnewb]

ive been doing research for days now to no end so i joined this forum for some help, my ecu had a burnt lead so i had it soldered to fix it and now my ecu doesnt send out a ground to click the mpi relay on and when i put a jumper ground on it to click it on the car will start and drive just fine until about 3000-3500 rpms where it gets a terrible misfire and feels like its not enough fuel cause when i come off the gas a little it clears up some. i also get a weird idle from 1200-1500 rpms randomly but other times its fine. i know i have a check engine light on for both oxygen sensors but would that make the car misfire like that? and what could cause my ecu to not ground my mpi relay to click it on? any and all help would be greatly apprecitated.

You should of had someone that knew what they where doing when it came to repairing it... but now, IDK if it would be more cost efficient to just find another ecu? Anyways, I've sent mine into ECMTuning to have done. They can definitely tell you the low down on the ecu. They are the most experienced when it comes to the DSM ecu.

i didnt personally repair it, i had someone i know that repairs ecu's do it. it starts the car but the blue wire with a green chaser (c130 on motherboard?) isnt getting a ground to send it over to the mpi relay so i made a jumper ground to get it to start. will any 95-96 eclipse/talon turbo ecu work in my car or will i have to have it flashed to my car?

what ive gathered so far is that i blew my sensor ground trace and thats what was repaired, no im getting no ground at pin 38 which is what grounds the mpi relay so that it turns on. now i figured out that it was my downstream oxygen sensor that blew the sensor ground because the ground touched the power wire. did that fry the connection for pin 38?

It's possible
