GAD-Motors tunes my A45 this is a proper ECU tune NOT a piggy back

This dyno shoot is with a tune only, they will be doing another tune with sport cats and air filters and I will share it when the guys share it with me.

Can't wait for them to change the turbo

dblock110

you said its not a piggyback? does this mean that group cracked the ECU?

dblock110

you put down 421 !? wild .. will your turbo blow?

dbasons55 - is that crank hp or wheel hp?

dbasons55

Yes GAD-Motors cracked the ECU and can flush there tune on the ECU no piggy backs, and the power is on the crank, as I said this is ECU only they are going to do a retune with a custom exhaust and filters, later they will strap a bigger turbo and push the max HP out of her, I will update as soon as I get updates.

The only issue is you will have to send them the ECU to do this!

dblock110

so its HACKEDDDDD omggg

this is huge news for sure

C63newdude

the 549 blue line is the Newtons meter and it equals to 404.92 lb-tq. the 427hp is probably to the crank and not to the wheels. There are dynos like the Ma-ha that they attach to the hub of the wheel and measures calculates crank hp since there are no rollers.
It sounds very feasible to me(427hp crank and 405lb-tq)..yeap!!

Having the ecu cracked is indeed big news. A little more power than most stage 1 piggyback currently out. Curious to see where it lands after the other mods.

This has *got* to mean that OETuning isn't far behind!!!

One question - Detectable or not?

Cracking the ECU on the new breed of motors is only half the job if you want to market a software map to the masses IMO. Most will be bricking it about warranty, so unless the software is undetectable to a certain degree during dealer visits, I would imagine the target audience is going to be very limited

dbasons55

It will be a while until we see someone else cracking the ECU if that happens at all

To my knowledge dealers can never detect a flush ECU

ML63 AMG

It's a super flow type dyno, Those are crank numbers of course. Still very impressive. I like how they intentionally shaped the power curve to make more peak torque higher in the Rpm to give it a more linear power curve. A lot of times on these turbo AMGs you see stupid torque at very low rpms then it tapers off. I assume this many also have been done to protect the transmission during launch control.

Once one company cracks, usually all the others follows. From what I've seen recently, Poseidon is the second company to crack the ECU. So it should only be a matter of time. This is likely going to kill the piggyback market, too.

Iggy Higgins

Before we all get too excited, let's see how transparent these ECU tunes are when a warranty claim goes in. I know of one owner who has had his warranty binned after his ECU tune was detected when making a visit to the dealer.
Don't get me wrong, I would much prefer a proper tune over a piggy back, but I don't think the tuning box companies will be shutting up shop just yet ;-)

dblock110

piggybacks arent PROVEN to be undetectable keep in mind . . .

Iggy Higgins

True, but I know what I would rather have on my car at the minute if something went pop and it had to go in to the dealer...

dbasons55

that's exactly why a piggy back is not the best choice for tuning a car, a proper tune allows the tuners to see more parameters in the ECU and can then play within the limits. Piggy backs are more like guessing and not exactly what I would put in my car I have had bad experience with them and wouldn't do it again.

tuning a car is taking risk if you are afraid that the dealer finds out you are better off buying a diesel rather than spending the time convincing people a piggy back is better than a flush tune!!

Iggy Higgins

At what point have I suggested A piggyback is better than a flash tune? All I have said is that at the minute with all the major manufacturers now having ways of identifying flash tunes quite easily, a decent piggyback does have advantages over a flash tune if you are worried about warranty. Not sure what this has to do with buying a diesel?!?!

If this (or any other) flash tune turns out to be undetectable and carries the gains mentioned in your first post, I will be all over it mate - trust me!
I just wouldn't be naive enough to think it is invisible. Given all the turbo issues MB are having at the minute, I wouldn't be prepared to take the gamble, so kudos for taking the plunge..

Time will tell I suppose..

dbasons55

I just want to clarify the functions of a piggy back for you, the ME17.7.2 is one of the smartest ECU out there, breaking it is something very very special, it means you can tune BMWs, MP4-12C, A45 and the new generation AMG's like the upcoming GT and anticipated C63

When you use a piggy back in any case and manage to hurt your engine a smart dealer will be able to detect that the car has different adaptations, that's of course the case when you use piggy backs it tricks the ECU in working in a way it's not suppose to work, but when you tune a car and tune the parameters within the limits then the car would never need to adapt, one major issue with the ECU is that it is very smart it does not like to be over driven by piggy backs and may put back the power to normal by recalculating its proper parameters.

I wish you all the best with what you end up doing to your car

Iggy Higgins

Likewise mate.

I will be keeping a close eye on how this thread progresses.

HIRO63

Is there any official announcement from them? What is the price?

RW Carbon

Impressive numbers for just a tune! Do you know how many Lbs of boost this is at?

ML63 AMG

Piggyback is always worse

dtc100

Some loss of peak torque at low RPM to compensate.

I have scared more people than I like on a daily basis in stock form. I can wait till the end of the warranty to do this, it shouldn't take long

Seriously after 10K if no warranty issue I feel comfortable doing a tune, as long as it is proven safe. The warranty risk is strictly powertrain. If you are a statistician, the risk at that point is very low.

soolman32

"Better" is very subjective. If your goal is to build up the engine, add various supporting power mods and squeeze out the most hp/tq out of your engine, then yes a flash tune is the way to go. The trade off is, the dealer will detect it and you will lose your warranty.

If you care about your warranty and simply want a bit more power, a piggyback is the way to go. A good piggyback will yield decent gains and be undetectable if the software is written correctly. Always look at dyno curve and see how smooth it is. In this case the piggyback would be " better".

Not everyone has the same goal. As I said before, curious to see where this lands power wise and long term sustainability for the engine health. Thanks for taking the plunge and keep us posted.
