has any of the x90 folks experienced this? when the car over boosts the ecu will cut fuel to the engine and it'll bog down until you let off the gas. it's happened to every single one of my friends with an x90 or x100 when they get around to about 1.0 bar of boost.

my question is that when I bought my car, it was completely stock and I've slowly been changing it up as money comes in. when I changed up the stock exhaust to a fence pipe, I was reading 1.0-1.1 bar on my boost gauge yet the fuel cut never happened. last week I finally got around to putting a downpipe in, took it out for a good shakedown and the fuel cut still didn't happened.

according to all the jzx guys over here, it's either a broken sensor or a tuned/aftermarket ecu. I havn't gone in a pulled it out to see but I'm just wondering why I'm not hitting this fuel cut.

I guess it's a good thing, but in the back of my head I'm worried that if one thing is broken then it'll lead to other things down the road and soon.

thoughts are appreciated

pull out your ECU and check it. If its tuned it should say something on it or in it.



That or you could have a FCD wired in without you knowing.
What is your redline?

yep, just as lucas said. probably probably a mine's, ph amuse, blitz, etc ecu or a fcd/bcc

not a big surprise considering you're in japan
