Check Light With Pfc ?

[Rezlo]

Hi guys,

RB25DET S1 into an S14 with a PowerFC, been running fine for a year, just recently ive been having slight missfire problems at lower rpm, I see in the last 3 days my check light has been coming on for about a second or two then going off normaly at about 3000rpm wot, all of my normal trip sensors (maf, knock, inj % ) are still quite a bit under their threashold, as well as this going on for longer than those warnings,

Now i remember when I used my blazt consult thingi a while back it didnt work (probably got one of the pins mixed when I did the M63 wiring re-pin, just wondering how to go around working out what is tripping it temporarily? with the PFC still have the consult features? or will FC-Edit be able to pick up error codes?

Thanks for your time.

why would u want to use consult ? the powerfc has its own built in diagnostics

use the hand controller and check out ETC, SENSOR SW CHECK

it will highlight which sensor is toast when the engine check light comes on

Because it comes on for a second then goes off, and does not repeat itself, I drive 80 miles a day, its done it 4 times now over the last few days, I cant keep it in that screen and wait for that 1second flash and try read that tiny screen before it goes out.

All the sensors check 100% when I monitor them normaly in the SW check screen.
