Hello,

I have been investigating into why my car wont perform on the aem box.

The log photo is below, the ignition timing drops highly.

On the map at the same point the ignition timing is around 30-34 degrees, but on the log it shows 23 degress.

The car is not recording on part throttle 40 degree of throttle, but then why this drop.

I have rechecked, there is no ignition trim for IAT, gears, or anything of such sort.

Please help urgently.

Sorry - just how modded is your car? Checked wiring grounds, connectors, etc. Is you harness stock except for the AEM?

 

You need to post your calibration, one of the other tables is obviously responsible for the timing drop.

What car is this, what are the specs, what AEM box, what fuel...was it TUNED, there are plenty of things you are missing here that we cant help you answer without

 

Also may want to set up your internal log as you have there a PC Log which is pretty slow in comparison when you want to find a problem.

 

Isn't that Normal? As RPM increases Timing should decrease. More so if your not running Speed Density(not using the MAP/MAF Sensor). Maybe your setup to use Timing based mainly off the Throttle Position Sensor(usually used on ITB Setups).
