Sup guys, I just picked up a 98 gsr but it's got a jdm b18b with an Si tranny. I noticed it won't go over 6500k. Now I haven't checked what ECU it's running yet but I will do that asap but what would be the proper ECU to run with a jdm b18b? I'll update as soon as I get a chance to look at the ECU. Thanks!!

 

pr4/p75. not sure why the transmission has anything to do with it.

 

It has a p72 right now, where does the jdm ls redline at, 7k?

 

tht sounds about right bra,but ima look and see if i can find out for sure,is it runnin funny or ANYTHING and dnt high rev it too much lol

 

its because you are running a vtec ecu on a non vtec engine

there is no need for a GSR to go past 6500 out of vtec so go get an LS ecu and try again

oh and there is no difference between the usdm b18b and jdm b18b, so please stop calling it a "JDM LS" and just call it an LS or a b18b

 

Lol aite will do, thanks guys. Yea it bogs a little takin off
