any reason taht this could be causeed, i was running her and all of a sudden at about 4300 rpms the rpm limiter kicks in and im like wtf, and i realize everything is way off.

i cant find much about it, i thought maybe vss but thats changed from the d16. doesnt make sense?

veracity

what car and engine combo are you running? vtec? mini-me?

turbo dave

95 ex coupe tach was off with the d16, redline of 5500ish

now i got a 4300 redline with the b18b.

i can feel the motor, and i know the revs aren't right

HondaTuner

So it reads 4300 but you can tell its much higher? Or what?

turbo dave

actually it redlines at a little below 5k everytmie

i dont know really im pretty sure though that it is revving to 7k

and damn its slow as hell too or maybe its just me what could this be from? stock civic exhaust? it doesnt really sound like a honda engine. meh maybe im not used to nonvtec/NA motors..

and im getting a solid check engine light but the car runs it wont read codes wtf mang.

i'll bet a quarter your in limp mode, chipped ecu? could be a bad chip job or a bad burn

nope got everything working today iac valve and iat valve were switched

i had the d16 ecu, and the b18b ecu and the tach is off on both

everything works

code 41 primary oxygen heater sensor ( i dont have one on this manifold)

but the car is very slow and idles rough, it feels like it dies off, and is just like not breathing maybe to much fuel i timed it as good as i could. im going to change sparkplug wires and see what happens, it doesnt stutter, but i can feel it gaining and losing power as i accelerate.
