alright so last night my friend calls me and says he is stuck and his car wont start. so i go and try to help him. everyone is like hey try using your ecu in his car. so im like ok cant hurt. i pop it in he goes to start the car and smoke starts pooring out of the ecu. im like wtf and unplug it real quick. i try it back in my car its a no go. it starts the car but its running at like 20:1 AFR (i have a wideband mounted) and it sounds like its on to cylinders. so i try his ecu in my car and it works perfect. so what cause mine to fry and not his?

 

What ECUs are you dealing with here? "His" and "Mine" aren't too descriptive.

 

does ur friend have aftermarket injectors? if so does he have low impedance injectors and did he use a resistor box? most likely u fried ur inector circuitry in the ecu

 

nope stock injectors. we both have p28's only difference is mine is chipped. we just want to get what ever is wrong with his fixed so there is no more fried ecu's

 

Open the cover, take a pic of what is fried and that might help a little...

 

i will take a pic. you cant see anything that got fried tho. it just smoked a LOT and it has that burnt smell to it. i dont understand. but i will take a pic 2morrow at work

 

your friend might had his IAT sensor plugged into the purge solenoid and the purge solenoid switch plugged into the IAT sensor. this will fry the IAT circuitry
