Ed, are you guys going to have a Coupe Pano Roof Meet?? You guys should really set one up, 6 heads are better than 1.
Sorry for my behavior Bruce and thanks for the info.

Ed, are you guys going to have a Coupe Pano Roof Meet?? You guys should really set one up, 6 heads are better than 1.

I'll post in the thread.
Karo is a good guy whose intentions are true.
Okay, I'm hoping to get a take away of knowledge here.
Can Star/SDS give me a real time A/F number. As in you get in the car, stomp it and have someone read the resultant numbers?
My beloved M111 engine is a lean runner. Using The SDS, it would seem that I could enrich to the stage 2 for 15% more fuel? Believe me, I could use it. I have a Kleeman Pulley, and a ported S/C.
I'll make my car the guinea pig for the M111. Karo, where you at!
Ed
I would install some data logging equipment or even get a code reader that has logging capability to monitor your O2 sensors and see what your voltage is which can be translated into an approximate A/F ratio. A wideband will give actual A/F reading as opposed to a narrowband that will give voltage.
Remember LEAN IS MEAN but.........RICH IS SAFE! I don't know if there is anyone with a full Kleemann package but has anyone tried to run a colder plug? 50-100 degree decrease in EGT helps A LOT!!!
Try Stage 1 first and see if that helps at all. How lean are you running?
Honestly guys I thought what I have brought to MBWorld knowledge and help wise and the cars that I have built would have preceded me in this forum but I was wrong. I thought at least some of you(Karo
) would have searched me out on MBWorld or the internet before flaming me.I am here to help the best I can and if I have access to more C's(besides C63's) I am sure I can find some interesting stuff for you guys to use.
It is all good guys!!

If we don't ask questions we don't learn so don't be hard on yourself. We have a number of so called tuners on this forum that are total idiots & do it for a living & are sponsors. A certain pulley manufacturer comes to mind. Bruce is of different mettle thank god!
Another thing to remember is that we are not talking racing engines here. Running our engines squeaky lean at close to stoichiometric will not achieve the best output - they need a little more fuel to do that. They will be a dog with 14 to 1> AF ratio. If alcohol is present in the fuel that really messes with things because it is partially oxygenated & only requires an AF ratio of about 9 to 1 to fully combust the alcohol portion which further fouls the equation.
I'm accustomed to tuning 2 stroke 500cc Honda & Yamaha racing motorcycles with tight squish bands & <1 thou piston to bore clearance. These beasts will produce more power the leaner you take them until they seize when you run them under trees in an oxygen rich environment.
So don't be tempted to lean out our cars excessively. You will ruin driveability & create engine stumble, hesitation & potential flat spots even with fuel injection. Our MAFs are simply not accurate enough to go for borderline tuning.
.Maybe Bruce can help, hey Bruce have you guys ever done the Fuel Tank Mod on the facelift w203?
I was soo close to getting this done and no joke my laptop battery was low and I didn't want it to shut down so I exited out of DAS (Ed is my witness to the horrible battery life) and now I can't find it.
The Gas Tank Mod (Shows actual miles left on a tank) can be done with DAS in Developer Mode.
ICM>Diagnosis to Plant Specification (Developer Mode)>Variant Coding>then something like tankinfo + reiche....
I saw it before and now can't find it. Maybe i'm not looking hard enough.

It's a very useful feature. John when you get a chance can you see if you can get it to work?? I don't remember if I sent you the Developer Key with the CDs but if not I can email it to you.

DAS Simulation doesn't show all items for every model in each class so I couldn't find it when I was in this mode. I tried though!
You don't need Developer mode for MANY items that you can change though normal SDS use. You just have to agree to transfer the coding and that will save it.
If only I had access to a couple of W203 and W204's.............the things I could find. I just finished updating to Xentry so now have COMPLETE ACCESS to W204's, W207's and W212's! Let the fun begin!
I was told by Rollnnn that there is a Gas Tank mod that he saw where actual miles are shown. I couldn't find it anywhere in the ICM. I even did an Initial Start and programmed the ICM and again nothing. That's when I went to Developer and looked through all the German (I did learn a little German thanks to DAS :-) and something that said tankinfo which I thought was the gas tank info and man my battery was soo low so I exited out of DAS so it doesn't turn off while i'm in a control unit.

Before:
Process: (notice those 2 "tankinfo" have to be activated" then you must go in actuations and "ECU Reset" all done in Developer Mode)
After:
Sorry for the crap quality cell phone pics
Summary:
ICM> Developer Mode> Variant Coding> Variant Coderung> Change to avtivate> Actuations> ECU Reset (always have to reset in developer mode while in regular reset is done automatically)
