How can I go about reprograming ECU in Pittsburgh? (No pulley upgrade.)

Who should I use?

Can MB tell if reprogramed and would this void my warranty?

How much would it cost?

Is it worth it?

chiromikey

not worth it unless you're recovering from mb's recall or absolutely need the limiter removed.

I doubt the dealer would be able to tell if it had been reflashed.They might be able to see some of the parameters have been reached or gone over.If they sent the ecu back to be checked they could tell but Ive never heard of that happening before.

The main thing is an ecu flash alone is a waste of money.

I brought my car in for all the recalls, and I could swear it was slower when I got it back... What don't I know about this

I'm thinking of doing a Powerchip without pulley, their dyno charts show 44 Crank HP, but the main thing is they will reflash for motor upgrades like when I add a crank pulley for $100.

Do the recalls slow the car down?

there's hours of reading for you. search key words like "recall", "reflash", and "ecu" in this forum to get started.

Chiromikey,

Yes... I found your thread expieriencing this problem a year ago... From what I can tell you got everything back save 10-15 hp.

So... Can I assume that Powerchip can take care of this problem? I'm going to send the ECU to them this Week.

Or.. Do you have to get the old S/W restored first?

Thanks,

chiromikey

unless you've had your original s/w copied, there is no way to restore it to pre-recall status. regardless, powerchip has been able to return power to reflash affected cars.

Zod

just curious, does this reflash effect 03/ 04 more then 06? or does 06 already have it when received?
thanks

Can Mercedes Do it? I think my dealer would cooperate. What version does it have to go back to?

I found the #2006-030011 service campain was preformed on the paperwork... Damm! Why did I find this out too late! I knew the car felt slower... Not even WOT... just punching it a little, I could feel the difference right away.

DRAT!

i'm not sure i've heard of an '06 being affected and iirc, they do already have the newer software from the get go.

mb cannot restore older versions of software. as much as your dealer would like to help after the fact, there won't be much they can do at this point unless you can get them to pay for an aftermarket company to do it.

RoydRage

I would pay for it... But where to get it done? I'm going to send the ECU to PowerChip, But it was stated that they even cannot get rid of the "Load Limter".

How can I get that done before the Aftermarket software is loaded?

Thanks,

RoydRage

I know I have seen posts where someone has gone with a Powerchip upgrade and been very happy with this mod alone. Were they likely down on power from the dealer recall? I've had the recall ecu flash done on my car and still ran a 12.4 completly stock. Many people on the forum have disputed that the flash affected power at all.

From my reading it seems like it probably did cause power loss for a few, but most seem to be unaffected.

Are you guys sure that there is little or no power to be gained from an ECU reprogram alone?

AdamG@NorCal

ECU upgrade alone will not result in huge gains. IMHO, it is best to purchase an ECU upgrade after you install headers, pulley, TB, etc.

Chiromikey: Do you have Powerchips phone number? I am pretty happy with the TB and Chris's Headers but I think the ECU reprogram might add a little more here. Can we send the ECU to them or do they need the car on site?
(ps. The fast idle has slowed down a little but still seems to idle a little fast at 750 rpm at idle vs 600 or so before the TB installation, Did you have this problem too?)
