No matter what I have tried it is always excessively rich on transition on the way down from throttle as shown in the attached picture. What is the cause of this. It was not like this on my E6K.

On haltech E8 running 550/1600 combo.

Dark green is the injector pulse. Light blue is wide band. The beginning of the trace has some massive injector pulse due to improper fuel pump setup. Red is TPS.

Any help will be greatly appreciated. My throttle pumps is wrecked. Base map and any other map looks like what everybody uses this base settings. This spring I have some settings I want to try but was wonder what was everyones setup?

Thanks

Which type of staging are you using? Also you need to take another log and include secondary injection times on it.

 

don't worry about the numbers displayed on your AFR gauge or log for staging in either direction, tune so that its smooth.

 

Common mode sequential injections. Bar 12.

Will not be logging again till summer.

Thanks for the help.

It hits an A/F of 9.3. ITs not right so I want to fix it. The E6K did not work that way and neither does a stock car.

The issue is if I increase the staging map it adds fuel through boost transition and back down again. On the way down it should be removing fuel not adding it.

thanks

 

I would make sure your staging bar and your fuel map corrospond with the correct change in injector opening. That's where having the secondary injection in the log really helps. I have had it off before when I did not count the columns correctly. ;(
