I have posted this before...
since I have changed my plugs to NGK 9s my engine has started to hesitate at 5000 rpm. anyone have any ideas?

could I have a bad 2nd turbo? (I hope not)

It sounds like you are hitting a fuel cut. Try starting out by changing your fuel filter. Also, what type of mods do you have on your FD?

SMIC, intake, DP, cb, y-pipe, ecu - mostly PFS crap

I think you need to have the ECU tuned. I think I remember another message you posted, and you are using the PFS ECU, right?

Did you buy it tuned for your mods?

trigeek37

yes, I have the PFS pos ecu....
I think I am going to ditch it and get a PFC...
but, the PFS ecu is setup for my basic mods, so it should work...

trigeek37

bump!

any help would be greatly appreciated

If you have the PFS keypad that comes with the computer hook it up and you should be able to find the fuel cut off setting, it should be set to 8100 RPM's if its not that than i suggest either messing with the settings a little bit or take it back to Farrell's

it was on loan from a friend that I was going to buy it from... I think I will buy the PFC instead... having done a great deal of reading here and talking to rotary people, I don't think it is the ecu that I want long term.
