Who is using the AEM EMS?

[p5150]

There are a few different things that could be causing rich fuel conditions:

Make sure that your baseline fuel pressure is set correctly. Once you have done that you need to right clikc on the fuel map in the raw view and recalculate the values for the change in fuel pressure and injectors.

Also, in the configure-> units section you need to make sure that you have it set for gasoline. Mine went to methanol by default. Even if gasoline is highlighted you should select another fuel, process it, and then go back to gasoline. I think this could be contributing to your problem.

You need to make sure you are familiarized with all different functions of the AEM to include the startup maps. What is your coolant sensor output reading on the AEM? If it is wired incorrectly and reading a consistent -50 degrees then you could be dumping fuel in that way...

Also try comparing your map to another cal file with File-> compare

Under sensors>MAP sensor>options check "MAP analog input". It should be set to MAP voltage.

We will finish tuning the car when he comes back from vacation.

Thanks for all the help guys, im sure there will be more questions and stuff to follow.
