Alright so my jspec setup arrived today and came with an n374 blitz access ecu. All I know is that its gotta be tuned in Japan, its kinda like rtek, and super rare.

Please hook me up with some info on this before I drop the swap in!

 

Non-tech and pic section isn't the best place to ask

 

Yeah it's better in the long run to get a American Ecu to help save you time and money. I currently have a panspeed one and it's a paper weight. What year is the car and motor?

 

generally the JDM tuners have stages.

stage 1 usually gets rid of the speed and fuel cuts.

stage 2 is usually like intake/catback tune

the next stage can be custom, so it'll be tuned for whatever mods the car has on it.

 

Car is an 89. And idk the exact year of the motor since I ordered it from Japan. Seems pretty stock though. Will this ecu work in my us car? And does anyone have an n370?
