why cant you use a n374 ecu?
I am in the process of doing my n/a to TII swap and ive read you cant use the j-spec ecu why is that? i mean i come from the 240sx community and you must use the jdm ecu or it will not work unless u go standalone so this isnt making any sence to me why you couldnt use it and not have problems.

Haven't we covered this N374 problem before... 9 times out of 10 the ECU won't fire the rear injector, simple as that. They are programed different. Some say you can put a Knightsport chip replacement in it and they work. I haven't tried this but I have heard of people that have done this with great results...

Not the guy who replied, but someone who a better reputation.
Was it Banzai Racing?
I dunno...I don't want to dig for it right now.
Someone also mentioned it had to do with a J-spec instrument cluster, but that was a hoax too.
I think the majoroity of the J-spec ECU's are JUNK.
Think about it...
"Knightsport" *IS* a J-spec ECU chip.
So how do you justify swapping a modded J-spec chip is the cure for a stock J-spec ECU???

mine has a stock n374. works perfect, but I want to install a chip for basic bolt ons.
most of the ECUs are pulled from half cuts and wrecks that sit in a junk yard for years open to the weather.
