Apexi fc diagnose

[Shamir]

Hi guys just need some help diagnosing the power fc. Does the black dots mean anything. Sorry Iam new to this.

[Shamir]

The car misfires mostly when it's cold and sometimes even in idle.

[Shamir]

It's a 33gtr motor standard with splitfires brand new.

[GTSBoy]

Black dots are the ON status of various inputs and outputs.

Your 02 sensor voltages are different as are your AFM voltages (AF-1, AF-2)
Might be worth checking out why that is happening (assuming photos are taken with car running)

[Shamir]

Yes they were taken while on idle

[Shamir]

Forgot to tell the motor runs rich most times

[Shamir]

I can even smell fuel sometimes while running

Did you look at what i was talking about? Im no expert on 25's but to me it seems you have 2 halves of the engine to look at and an airflow meter and o2 sensor for each half of the engine. They look out of whack to me.
Do you have a dodgy injector? Has it been tuned?

[GTSBoy]

Actually, now that I look at that odd O2 sensor reading......how the hell does it get all the way up to 3.96V on a sensor that should top out at 1V !?

I have just bought the car and it had this motor in it with the apexi fc. I will get it tuned for a start if that needs to be done. I thought I would get some advice first. Haven't checked the injectors yet sorry.

I would not have a clue mate. They do fluctuate in the readings.

25's?? It's a 26.

[-S-]

I would send it to a tuner to have it checked

[Shamir]

Thanks for all the help guys.

[Shamir]

Are you able to run map sensors on this model fc and delete the AF meters ?

[GTSBoy]

No.  They do one or the other, not both.

Most likely tuned related, plus it looks like one of your O2 sensors are cactus and your AFM values differ quite a bit between the two. They will be contributing to the problem also.

Thankyou I will get that checked as well .
