Thread: Possible bad ecu?

Hello all, I purchased a nismotronic chipped ecu recently from John and was having some issues. The ecu is just a basic one with a standard ve tune running ve maf. I finished my swap into my b13 se-r and it won't start with the nismotronic ecu. For some reason the fans come on but it'll just crank and not start. However, when I install the stock de ecu it fires right up. Is this a sign of a bad ecu or am I doing something wrong with it? Ive tried searching but.can't find anything. I really need to get this car going for my daily. Thanks for the help.

Did you order it with a base file on the board? If it hasnt been registered and a base file flashed on then it will be in limp mode with fans running.

Yea, I ordered it ready to go and direct drop in as I'm new to the tuning part of this. That's why I went with this base ecu setup. So it was supposed to have the base file with the ve tune on it.

check to make sure the chips are sat properly

also try to reset the ecu.

Ok I'll check that. How would I go about resetting it and would it loose it's program?

no the chips will only lose their data in 1 of 2 ways. #1 an electric current is applied to the appropriate pins and the data is erased through software, or the chips are exposed to a ridiculous amount of UV light since they dont have windows built in.

Thank you guys, I pushed the board in tighter and it started up. I appreciate everyones help immensely!
