motor 1994 civic ex

[wiseguy01]

is it carb or fuel injected more info please

[1BOSSMAN]

Fuel Injection Checked Timing Fuel Pressure And Looked For Vac Leaks

check TPS. any CEL's? what ECU you runnning?

[1BOSSMAN]

A Chiped P28 Out Of Car That Was Running So Thats FineAND NO CELS

[Greenblurr93]

why is the p28 chipped? i tend to believe something happend with the chip, pull the jumper out so it reverts back to factory chip and try that

Computer Came Out Of A Running Car That Was Wrecked I Was In It 2 Weeks Ago That Car Was Quick No Problem With Rpms I Even Tried A Stock 1994 Civic Comuter Still Same Thing
THE CHIPPED COMPUTER HAS A SKUNK CHIP

[Greenblurr93]

but my question is whats dont to the car to require a re-tuned ECU?

[1BOSSMAN]

New Short Block Bored Redone Head Injectors New Header Back Exhaust Race Cam Race Clutch All Parts New Type R Trans I HAVE TRIED A STOCK COMPUTER AND STILL THE SAME

[Greenblurr93]

ok, now we're getting somewhere, now we know its modded.... was the chip bought off line? or did you bring your car to a tuner to tune to your specific setup? how much bigger are the new injectors?

I still think its something with the ECU.. when you mod an engine like that, you cant just throw a chip in it and expect it to run.. get it tuned and ill bet you fix it

[1BOSSMAN]

yes i had it tuned from a engine builder who dynos and handles all imports he built my motor it was in 94 civic had 8.5 comp.pistons ran greddy turbo and turned 10 in 1/4 motor blew redid it dome no turbo installed it in 88 crx only prob is wont rev over 3500 in any gear how is it possible to tune it when it wont turn over 3500

[Greenblurr93]

i think something got screwed up in the chip.. do you have a wideband? if so what AFR's are you running?

[1BOSSMAN]

no wideband and put computer back in other honda ran fine

[Greenblurr93]

right, was the ohter honda as modded as yours? with the boring and P&P your getting alot more air in there, and if the ecu isnt setup for it then its gunna go nuts with everything the sensors are sending back, which will make it run like shit. Whereas is its set for a relativly stock configuration (the other car) it should run fine. i would also check out all your other sensors to make sure they are still working correctly and sending accurate info to the ecu.
