This software is a Bosch / MB standard software program that advances the timing somewhere in the range of 2-5% and does not alter the AF ratio or increase the performance of the FMU... It is the same program that everyone sells (powerchip, superchip, etc.) for $250-$650. You should realize a minimal hp gain ONLY because of the advanced timing...
The only way you can goose more substantial HP out of timing this car is if you spend hours remapping the ECU in conjunction with the FMU and altering the lambda and 02 sensors... And then testing it on a dyno... And I can pretty much guarantee they have never spent any time doing baseline tests with this W112 engine, then custom modified ECU based on the AF ratio and torque curves...
I would definitely take them up on their offer of a dyno before and after if my car was stock... But mine is so screwed-up with wacked-out modifications, it would not be a fair test...And my software was custom programmed by one of the former Bosch programmers and I don't want to mess-up the hard work we've done so far...
If they want to dyno my car now for free, then install their software and re-dyno it and do a comparison with my current software, I will be more than happy to bring my car to their facility on Wednesday of next week, providing they can guarantee that they can reinstall my current software after the test is completed...
HDDP,
I'm not following where you want this thread discussion to go - are you saying that we can't tune A/F, that we don't custom dyno tune, that we don't have the hardware/software to back-up your current software flash, that we don't actually have a retail location...
Here is ANOTHER example of a recent customer's dyno-tuned "lowly" C280 and if you happened to know, the make and model of this Mercedes-Benz comes with a non-reprogrammable chip - so how did we do it? How did this N/A vehicle magically gain 17 tq while the customer was watching us work on the dyno? Ebay fairy dust?

How is it that a Renntech StageII+ C32 has the following A/F ratio (@ 354.8 TQ/35.5 HP - Mods: Renntech Pulley | Renntech Stage II ECU | | Evo Headers | Greenfilters | SL55 Splitter | Denso IK-20's | Magnecor Wires | Resonator Delete | Sprint Booster | Evo Phenolic Spacer Kit | Eisenmann Race Exhaust | Random Technology 7000 Series Racing Cats | Custom SS Tubing w/ Magnaflow Y-Pipe):
while the SpeedInnovation C32 has the following (@353 TQ/351.1 WHP - SL55 Splitter, Evo ODPS, Filters):
If anyone
actually cares enough to read through the thread just to be informed:
http://forums.mbworld.org/forums/sho...d.php?t=177303 - you will notice we aren't even finished tuning that car yet (and it has yet to make more power presumably further on the top end).
What I'm surprised to see (and apparently we have seen this before, even before I), is that the skepticism and pessimism about 'true' tuning is so tainted that it's nearly completely tarnished. It takes a few bad eggs out there to "mess it up" for everyone else, I suppose, is the highlight of the discussion. I probably can't "say enough" about the subject of tuning without sounding extremely defensive (oh, great).
What have you got to lose by taking this chance - we have a 30-day money-back guarantee and are LOCAL to some of you folks. Look, let's face it, we don't have every car in the world to dyno right? And not every customer comes to us saying: "Yes, I'll gladly spend a bit more money to have my vehicle dyno-tuned", (rather opting for in-house DME retunes b/c of time/money constraints) but we HIGHLY suggest it for individual peace of mind, especially with an aftermarket mod list. Can we provide free dyno-tuning to everyone? No, of course not. (But that C230 was worked on for 2+ hours of dyno time to get where we wanted it to be and it was reseller sponsored by K1Motorsport).
HDDP, what is your complete mod list? When is the best time either I or our technician can reach you?
There's a lot of potential for you guys as far as ECU-tuning - but man, ya'll really make us stretch for it.
