hmmm Yummy Stuff should i get me an Early Christmas Gift?

So has anyone taken advantage of this? Any feedback?

I also want to know if we can send in our ecu's a little after xmas.

Still interested in this.

Feedback anyone...anyone???

will this work for a c240?

Same Question...2006 V6 here. If so what are the gains?

No response from the seller and no feedback...guess I'll pass.

any shot extending this deal through the holidays? i've gotta drive my car back from the relatives house before i'd be able to ship out the ECU and that won't be until after the start of January?

Yes we do offer tunes for the C240 and the C230 v6

Are the C230 ECM tunes E85 compatible? I have yet to find anyone that tunes the 07 2.5L M272 ECU that is E85 capable.

Hey hanknum,

For the 320 you might not get gains that the m272 will. I believe this is due to the m112 being SOHC 3 Valves per Cylinder VS the m272 which is DOHC and 4 Valves per Cylinder and I think the most significant is the airbox. The m272 will gain 20hp with just a tune but I believe the m112 might gain 10hp but if you mod the airbox you can too reach 20hp (estimated).

Since the m272 guys over at the w204 forum said they felt insane difference especially on high speeds I have a feeling you might too. The most important of these tunes are throttle responce. Almost everyone who has got a tune has mentioned how much the throttle responds better and I don't think this is because of the added hp but because of the tune.

I'm trying to figure out a way to boost my c350 so I'm going to pass on this tune at the moment but for 300 dollars it is really worth it. Also I don't know if they operate like Kleemann who offers a free reflash (if ECU was overwritten by dealer) as long as you pay shipping.

Good Luck,

Karo

How do you plan on increasing boost on a supercharger with just an ECU flash? Turbochargers manage boost with wastegates that are set to specific pressure points manually or electronically (electronic wastegates rely on a boost controller and not the ecu)... you wouldn't need to modify the ecu to gain boost on a turbocharger. You would need to modify the fuel/air/timing maps to gain maximum efficiency out of the additional boost, hence the necessity of the flash. Superchargers produce a set amount of boost by the speed and efficiency in which the fans can put pressure against the valves in the head. This is something that is very mechanically set, you won't gain boost unless you modify the drive ratio (aka over driving the fans with an overdrive pulley) or by replacing the fans/blades for more efficient versions. But you wouldn't be able to accomplish additional boost this way with an ecu flash. I guess in rare systems you could waste gate a supercharger by venting the head? but I am not sure what sort of performance you would expect to get in doing so...

You are going to gain a lot of performance (forced induction or N/a) out of a flash. More importantly, if the flash is made with existing mods in mind you can extract more horsepower out of those mods. Your car has been bred out of the factory with a very timid understanding of its potential... manufactures have to take in account longevity of parts and fuel economy. Additionally they often take a single program for every car they produce which could have varying tolerances and these variances must be accounted for by modest fuel/air/timing maps. Additionally, you can flash a vehicle to more precise timing (advanced a few degrees) and it will make better use of the energy in fuel. By doing so, you will eliminate your ability to use lower octane fuels which the manufacture wanted to market the vehicle for and gain more horsies. You can also flash a vehicle to move rev limiters (get rid of the 4k idle limit), you can flash a vehicle to disengage the EGR (which will add ponies on the highway). Meh, i'm done.

that's because ethanol is a dream and a stupid one at that...

There is alot to consider when dealing with E85, the fact is that the air fuel mixtures are so vastly different (gasoline 14.7:1, e85 9.79:1) that most mappers won't waste their time doing both. The fuel injectors have to push approx 25% more fuel when firing e85. This is because e85 has approx 25% less power than gasoline. YES IT TAKES 25% MORE E85 to push the car the same distance as gasoline, e.g. what gasoline does in a gallon, e85 takes 1.25 gallons. In addition to this, e85 has high knock resistance but is highly susceptible to pre ignition.

Are you by any chance related to a member here named Glyn (Glyn M Ruck)?

And for anyone in the SF Bay Area, Eurocharged will be here in Fremont on January 9th doing custom dyno tunes. Maybe you can just stop by and get a reflash....

there's an error in your first paragraph. the ecu controls the boost controller which is connected to the wastegate. wastegates are purely mechanical on turbochargers.

explain to me how the supercharged cobalt ss gets more boost from a reflash...it's because the boost controller bleeds off boost at a certain level, and it's electronically controlled.

Thanks Karo. We'll have to wait and see...don't know what I'm going to do right now.

Have a happy and safe New Year.
