Tuning My Mercedes

[Guest nismo502]

Today my friend put my car on the dyno and tune/reflash my ECU. This is the results

Dynochart is for power at the engine for a stock standard W203 C200. The line at the bottom is for before tuning and on top is after tuning. To get power at the wheels, factor in drive train loss of 20% and it looks about right. As you can see on the dyno chart, I gain about 9bhp on the top end. What is actually more interesting and useful is the power I gain across the entire rev range. The dyno chart shifted upwards even considering there is no changes to the boost I am running. On the road, the car is much more responsive and pulls substantially better mid low and top end. Besides that, pedal response is more sensitve as the tuning includes Fly by wire control. It basically works like the sprintbooster but better because pedal sensitivity can be adjusted based on how sensitve I like it to be. Unlike sprintbooster, there is no settings available. I am actually very happy with the performance gain.

Next, I will try airfilter, exhaust and pulley. I am looking forward to what additional boost will do to the car with a tune/reflash as this is where it will excel. Will post my findings soon.

Oh by the way, my boost dropped off after 5400k rpm. I was told my supercharger belt is slipping. If I fix it, power gain will be much more substantial.

Free plugs: Tuning is available for all fuel injected mercedes and not just W203. you can pm me for contacts if you are keen.
