Topic says the problem. My car works fine with original ecu, but with pfc it idles good and everything but wen i try to rev engine it revs about 1 sec and then flats to idle. What can be the problem. it seem like it cuts fuel.. also i noticed heat warning light is on all the times. My car is -93 fd with nonseq, intercooler, intake, dp, catback, rad upgraded.. Also i checked sensors and vta-1 was highlighted and reading was 4.86, my car water temp was 82 when i started installing it cos i was just driving with original ecu. The water temp correction highest point was 80 but i didnt dare to touch it cos i dont have manual for pfc and dont know exactly what it does. And sorry for bad english. Its not my native language

 

Read the stickys above to get a manual or go to the APXI site to get one.
Read page 35 of the PFC manual.

Your TPS might be bad that is why it is highlighted because at idle both voltages should be low. Read about it in the FSM section "F".

Test it using the commander and your foot.

 

problem solved, tps wasnt installed properly. i had bought tb from some guy and should have checked that it. now everythings working fine
