Hondata

Found the problem finally! Something to do with the purge valve between the charcoal canister and the intake manifold. All i had to do was unplug it from the harness and problem fixed.

I've started to drive the car some more and noticed the issue now seems more intermittent. Like I said before it does it only when the car is HOT and heat soaked, if I cruise around town stoplight to stoplight the problem occurs, but when I cruise the highway it seems to slowly disappear. The rich ...

Like title says, when I am cruising 2000 and up RPM at about 3-4% TPS , and SLOWLY press down on the throttle to accelerate I am getting a horrible rich AFR spike. I am slowly pushing the throttle and holding it only, say from 4% tps to 8% tps. Wideband will read down into the high 10 AF ratio for a ...

after searching around this forum some more, I found my answer and am pleased to say no more problem!!

This forum rocks!

Thanks for the help Johnny 9

Thanks!

Is there something Im ...

300hp on 8 lbs of boost will take more than just a good tune and a good turbo. Headwork + Cams + more headwork + hondata. Im sure im missing something though.

Dont use the PCT pistons. 11-12:1 comp ratio ftl on cheap cast pistons and stock rods!

ok, after some research I found my answer, Although I am unsure of what to buy for a relay. Radioshack/ local parts store carry one that would would work?

It seems as though people have problems trying to wire the relay up correctly. Is there any tips or tricks before I start? Or would it just be ...

Hey guys, I have a P75 (non vtec )ecu with s300 installed and I am just wondering what I will need to do to run a B16a with this ecu/s300 combo. Will I need to add the vtec components to the ecu or is there a way to change the vtec output signal to run on a different pin?

Any help would be greatly ...
