i have a 92 civic with a b16a swap. i put in the knock sensor and everything with no check engine light. yet every time i puch it my p30 ecu will bog out at 7500 rpms. could it be a fuel problem? is the ecu suppossed to redline at 7500? any help would be nice. thanks

 

Stock Honda tachs are always off.

 

im running the jdm p30 in my hatch it goes to 8500 tho i dont take it there much with the d16

 

JDM OBD1 P30 ECU:

Redline = 8900 RPM (Fuel Cut)

Speed Limter = 200km/hr or 120MPH

US spec should be similar, if not the same.

 

mine is a udsm ecu. i found out today that it cuts me off at 7500. u thyink there is somethin wrong with the fuel that i might be leaning out?

ok wtf. this has to be wrong.

1. redline does not equal fuel cut.
2. redline is not 8900
on the jdm b16a sirII it is 8200 rpm
the fuel cut is something like 8349 rpm if i remember correctly.
3. oem tach's are alwasy off like some 1 noted.
4. usdm b16a2 has something like 8000 rpm redline.

 

8200

 

u think it could be a problem with the furl pressure regualtor or somethin like that. cuz my car stops when it hits 7500rpms and my motor itself should run good no check engine light
