I just installed my Apexi power fc (FD3S)and mapped the injector map, ingnition leading, ingnition trailing, but the exhaust warning light keeps on flashing. my motor is street ported,dp, mp, cb, Power fc, twin air cone filters, air pump removed. people told me its the cheap fuel, and others said because the injectors are set at 100% duty, im a bit confused because the Greddy warning air fuel meter with a four wire o2 sensor is reading reach fuel mixtures. help.

 

The PFC only gives warnings for certain errors, in the manual. It ignores most missing solenoids, but does expect certain sensors to be attached and in good condition.

Go to the ETC - sensor screen and check for bad/missing readings. This should point to the bad or missing cause of the error. Unless the PFC itself is bad!!!

 

I did and the sensor check mode displayed three black dots do they all have to be ring dots or black dots or is it normal to have different colour dots. or can it be the harness is not secured properly, help.

 

and by the way the pfc is brand new.

 

The exhaust temp light flashing is a warning for knock at/above 60 or inj duty cycle at/above 98%. You can turn this feature off by following page 36 of the pfc manual. Go to ETC screen and select Function Select ...

With the datalogit you can alter the setpoints as well.

Sounds like you are experiencing high injector duty cycle or high knock. It is simple to monitor both on the Commander, suggest you start monitoring them asap to verify what is going on.

 

can i turn down the injector duty to 98% because its set at 100%. or is it always 100% duty cycle.

 

the exhaust worning is still flashing i checked the sensor screen and the oil pump is not responding well so it flashes once and as soon i touch the troutle is flashes five times and that is the injector duty

 

sorry but you are incorrect. Knock will illuminate the CEL. The exhaust temp lights as Chuck stated, d/t bad or missing sensor.
