R32 Gtr Runs Rough After Stk Ecu Install

[joeleo87]

Ive been having some trouble with my GTR for the last month or so.

it would occasionally cut out... when ever it felt like my auto elec thinks he has traced it back my mines ECU, after testing everything else that could have caused the problem.

so ive borrowed a stk ECU from a mate and got my auto elec to put it in so we confirm it was the ECU playing up but now my car runs rough as guts from 0-3000 rpm, im talking all you can hear is the exhaust popping lol.

also maybe unrelated but my speedo is limp from about 0-40kms? like it doesnt hold in the 1 place and climp steadily it fluxuates???

cheers

If your ecu isn't getting a proper speed signal it doesn't know when you've come to a full stop so the ECU doesn't know when to go from overrun to idle..

ok so im assuming that there is a sensor out?

what would cause this problem then?

interesting. i recently had to remove my power fc and replace with a stock ecu and my car is also running like balls.

[joeleo87]

any1 got any idea on how to fix this problem?

[joeleo87]

so me and shredder are the only ones to have this problem when replacing an ECU with a stk ECU???

O.o

we are fecked...
