95 civic
94 ls motor
450cc injectors
crower turbo cams and retainers ect.
stock everything else
tuned to 10psi only made 194hp


ok i paid someone to tune my car. i ran the FMU for about 2 days to work out any kinks in the motor since it was a fresh rebuild. i set the base timing and everything else to spec. installed a fuel pressure regulator that raised fuel pressure depending on boost..

i am sure this is just for a FMU setup
and the car ran good. i did hit boost just a few times to ensure everything ran good.(this is all before the tune)


now i have a chipped ecu for chrome
took it to the shop and they dyno tested it during the tune
instead of using the stock fuel pressure regulator they insisted on using the one that came with the FMU kit. i think its a 12-1 ratio

the car idles like **** after the tune and is sluggish while at lower RPM's. so i replaced the aftermarket fuel pressure regulator with the stock regulator and the idling got better but not great.
hooked up the virgin ecu and now it idles and drives great like it did before modifiying the engine.

so my question is should he have used the stock regulator and not messed with the regulator that came with the FMU setup?

(i am not driving the car now i was trying to figure out why my idle was screwed up) he told me it was not his tune so now i know different, i think it has to do with the aftermarket fuel regulator?

 

kit is the Rev Hard stage 2 turbo kit

 

Bring the car to a better tuner. I would suggest a 255 fuel pump.

 

yeah i have the 255ml pump

but should i make sure that the stock fpr is used?

kev

 

The vortech FMU that comes with the revhard kit should NOT be used if tuning with ems and larger injectors.

 

thankyou, you hit the nail on the head with thatone
