I have a 2001 Mercedes-benz SLK 230K that I have converted to turbo via a Garrett GT2971R and have a bunch of questions regarding idle and dealing with the DBW ( drive by wire )throttle. The car has been running decently (occasional boost cutting) with the factory ECU with a stage 2 tune on it. This being said, I'm exhausted of having the reset the car when the ECU pulls fuel when the boost limit is encountered.
To remedy this, I purchased a 0.4.3c kit and assembled, loaded the base tune and am in the process of installing it in the car. It will be running in parallel with the factory ECU, as I'll need it for throttle control.
I understand that Speedy can't control the throttle, but how do I adapt the speedy to the DWB for idle control? The car doesn't incorporate an idle valve as it's electronically performed through the throttle.
Also, like I've said, I'm new to this. The SLK has Beru 3-pin smart coils and Siemens 330cc injectors. How do I put a load on the factory wiring to eliminate a CEL and avoid boost/fuel cut? I believe this car cuts fuel when it hits the boost limit, as my AFR gauge will show a max lean condition when the boost limit (11.5 psi) is met.
