Does anyone know of a shop that has a DSM tech or know of anyone who has multiple years of experience working on DSM’s?
 
What is the issue you are having? If its something simple I may be able to help.


Where is overkill performance located? The problem I’m having is my car runs normal with an air fuel ratio of around 12-14 but as soon as I turn my air fuel ratio gauge it goes completely lean to around 16-18. My AFR gauge reads lean the whole time. Also my idle is off. I’ve checked for leaks and the ISC motor.
 
Overkill performance is in Sacramento near arden area.
Do you have your steering pump sensor hooked up. Thats the only thing i could see causing the car to lean out while turning. What software are you using and setup on,the car?

I do believe the power steering pump sensor is connected but I haven’t checked it for damage yet. I didn’t mean it goes lean when I turn, my apologies. It goes lean when I turn my AFR gauge on. It’s wired into the lights, so it comes on when the lights are on.
 
@Wuino316 this is the guy near you

Oh ok. So whats happening is that when,your lights come on the voltage changes. You need to tune the car for for that by adjusting your injector pulse time v voltage. What tuning software are you using?

I’m using ECMLINK.
 
There should be a spot where you should be able to adjust the injector time,vs voltage in there. I would log them to,see what its doing.

There is a spot I forgot what it’s called but it allows you to tune for different voltages.
