There have simply been too many blown motors due to unsafe tuning from a few different companies. It needs to stop. I have done ECU analysis of blown motors 7 times just this last summer from customers with other tunes, and that is too many. We need to realize where the power limit is on the car, and take a step back to appreciate what the purpose of Mercedes tuning is for. The AMG platform is wonderful because it can provide us with a daily driver that is smooth enough to carry grandma in the car, but absolutely fast enough to destroy most of the cars on the road with just a few modifications. This should be the way that the tune is done on the car. Safety and longevity in mind above the absurd race for the biggest HP numbers. I strongly believe that the limit of these motors has been pushed time and time again, and people who are just looking to make a fast car faster end up with a mountain of troubles because of it. Years ago, blown motors started showing up and the solution was to always blame something mechanical on the car, when in fact it was due to the tune. These cars are not testing a new motor design, or R&D a new type of product. Most of the horror stories I see, and provide ECU analysis for, have simple modifications, such as a s/c pulley or headers. These customers are left with horrible experiences costing them huge amounts of time and money to fix, and it scars them from modifying cars in the future. At the time of writing this post, Logic Lab Tuning has sold over 100 Mercedes tunes without an engine failure of any kind at all. The reason for this is simple. We do not run an additional 8 degree of timing on top of the factory maps, we do not lean out the fuel mixture to gain every last bit of HP that the car has to give, and most importantly, leave the Mercedes safeguard coding in the ECU in place so that if there is a mechanical failure the ECU can compensate for it.

On another note. The MyGenius unit that people have been purchasing is a wonderful unit that we have had excellent success with. If you have a unit from another tuner that you find is not operating, let us know and we can probably fix it. It takes a lot of work from the side of the tuner to have these units properly set up and working correctly.

Hello, since when does a leaning out of fuel mixture give more HP?

iTrader: (1)

since the gasoline engine was invented

LoL

Crissus

So if we take Lambda1 (14.7AFR) as base and go leaner from there, does it still produces more power???

C3Duece

Yes..to a certain point...until it gets so lean it dies or windows the block under boost.

I just keep getting pictures like this over and over again. Make sure that you are checking on your car and tune to keep you from having to get a new motor!
