I don't have any good pictures, but are you sure you are using the right wires (pin 90);
Orange is receiving from the air flow sensor.
Pink is out to the ecu.
I have seen some write up saying to use the wrong wires on the S-AFC harness.
Do you have the right type of sensor selected (Karman)?

 

[miniturbo23]

yeah its orange goes back to back to the ariflow sensor and pink to ecu, also I do have it on karman. the Afl is the one not reading throtle rev and everything else is. do you know what could cause this?

Here you go, this might help.

I took the AFC off and my car still running like crap it wont pass 3k rpms or boost the gauge says its running lean but I dont get why since I put the venom fuel rail along with the 255 walbro fuel pump. anyone got any tips or know whats wrong??

 

[spyderturbo007]

Did you reconnect the MAS wire after removing the ECU?

Do you have a FPR for the pump? How would your boost gauge tell you your car is running lean? Do you have a wideband or a logger?

it sounds like its not getting an airflow reading ive forgot to reconnect the MAS befor and sounds like what u just described. make sure all you connections are good

Yeap, its not passing 3000k because the motor is not getting a maf signal and thats the CEL. What happens is the motor run pig rich to be safe, but its so rich the engine wont rev. I pulled like 60% global when I couldnt figure it out and it still barely ran. Then after two days the CEL finally came on and said had a maf error. I just reconnected the maf wire at the ecu and i was good.

this is why I love you guys!!! I will check this on my break I work from home so I'll give it a test run. beside checking that wire on the ecu do i need to do anything else?
