I did a search and found nothing, so my question is this: I have seen people say that their JDM B18C has a top speed limiter/governor at 120 mph. I have also seen people say that they have gone 150 mph in their USDM B18C1. Do the USDM B18C ECU's not have a top speed limiter, or is it set higher than the gearing will allow it to reach? Thanks.

 

all JDM ecu's have a speed limiter
USDM ones done (i belive OBDII ones do, but i could be wrong)

 

i know my 98 gsr doesnt have a speed limiter. 152 mph @ 7600 in 5th!!! DONT EVER DO THAT!!!!!

 

do the b16s have a limiter? is the only way i could tell is if i take it out, and push it?

 

Thanks guys. One more thing, is the gearing the same for both JDM and USDM? The reason I ask is that I am doing a swap soon and I am stuck on whether to buy a JDM or USDM engine. Has anyone used a USDM ECU on a JDM engine? Any problems?

well, half of my engine was jdm, so, no there are no problems with running a jdm ecu on a usdm engine. but i might suggest getting a chipped ecu or a socketed one so you can swap out chips (mugen, spoon, etc.) thats what im doin now that i dont have to worry about boost on my new project.
