I tried adjusting the TPS and still no good on the idle. I know i was supose to set the tps with the harness disconnected, but i cant seem to get any readings from the harness when disconnected (S5, i checked the end that is connectedf to the TPS) compression is good and no signs of vac leak (or do i just not notice?)

the process is like this...i start the car, it starts up, revs to 2k for around 10 seconds, and suddenly drops to 0 and dies, have to hold on the gas for 2 minutes for it to warm up (BTW, if my temperature gauge broke, how can i fix it?) after warm up, the idle would roughly jump between ranges 1k to 100 rpm and sometimes dies.


the car is a s5 91 coupe with a s5 jspec swapped in and uses a N/A chipped ecu. can this cause that problem?

please feel free to give any ideas that can help me with these problems. i really want to get my t2 running. thanks!

 

Yeah you are going to experience lots problems using a N/A chip with a S5 TII. Besides fuel and boost readings being mad different , the ECU is made for a N/A, you are going to experience all kinds of problems until you get a turbo ECU. Sorry dude but dont expect a quick fix until you get a new "brain" for that ride.

 

kool, will the t2 ecu bolt rigtht onto the n/a ecu harness?

 

any more ideas???

 

anyone with similiar experience?
