Thread: Next performance mod?

Try using that fpr a bit. Do 4psi to start and see if you can get it to run somewhere near normal.

ecu

tune

intake manifold and/or hcr pistons

peace

yeah i'll get on that stuff once i get out of the debt that i got my self into with my damn credit card!

Benito Malto, the car drives perfect around town, the afrs stay between 14.5 to 16 afr and fluctuate when im at a constant throttle position from 14.X to 16.X. Should i bump up the base pressure or should i adjust it with the vacuum line attached

Just adjust fuel pressure with the line atached until wot afr's are safe.

well i did do that at the beginning of this week, but it almost sounded like the slightest misfire at idle and driving around town it wasn't responding as well, not to mention the power didn't feel like it was all there and wasn't reving that "clean"

Well fpr is a crude tuning tool. IT just does across the board adjustments.

I would rather it have a bit less power and stumble a bit down low versus risking a mess of detonation if you get on it too much.

SR16VE transmission and Fidanza Flywheel at the same time

^^^^ thats a good one.

forget anymore mods till you get a proper tune. g/d jwt..dump it like a hot potato.
if you MUST drive it, do what ben says with the afpr (a band-aid) till you get a real time ecu, or park it.

BTW what fuel pump?

Stock ones lean out on VE's.

Almost positive it has a walbro 255 in it, and as far as changing the transmission and flywheel im not looking to get that serious with it. I already have a semi built tranny with the shorter final drive,along with the fidanza 8 or 9lb flywheel.

And to be completely honest, i am not sure if the wideband is completely accurate or not since its been on he car for almost 2 years now.
