<<< Peformance ECU upgrade for W210 E55 >>>
We now have a Holiday Special on the Performance ECU Upgrades available for the E55 AMGs. They are now available for $50 off.
Standard pricing:
- E55 = $325
AMS pricing:
- E55 = $275
Dyno Charts:
- E55 = W210 E55 AMG Dyno
*This tune is also available with our Stage 1 Performance Package (ECU + Pulley)*
If interested feel free to contact us via Email for more details.
The headers are already out we just haven't had a chance to update the website, we will be doing that by early next week. The tune is compatible with all those components but is not necessary. You can get the headers or pulley separate or all together, it doesn't matter. Our Stage 3+ setup is different in that it is a much more aggressive tune designed for intake & exhaust modified AMGs to extract the maximum amount of performance possible. Please check our website next week for updates. Thanks
Very simple, you just take out your ECU, ship it to SpeedtuningUSA, they reflash it for you and send it right back. Express shipping is standard $20 rate for anywhere in continental US. If you do all the work yourself its just as listed, if you have a shop do it for you (not really necessary) then they may charge you alittle bit (but honestly its so easy the most they should charge you is 1 hour of labor. If you need to do anything else at the shop then you could just tack on this and save some money as they probably would not charge you extra. It is a quick, easy and painless process to do. Hope that helps.

I might have to ask for a walk through when i'm ready to remove my ECU. I should be ready for this and the X-Pipe mod just after Christmas. I'll be badgering you for help.

Thanks again bro!

Armani - SpeedtuningUSA does all our ECU programing, we simply offer it at a significantly lower price. SPTUSA has reprogrammed many of the ECUs on MBworld and has done an excellent job.
Esh - during normal driving there should be no difference. Its only under WOT that you might burn slightly more fuel but even so it may be difficult to notice. The only way to really get more MPG is upgrading other components to improve efficiency of the engine.
Hope that helps.

The stage 2 software (+) allows for a 6400rpm redline when driven in manual mode (normally in D its still around 6000-6100rpm).
cdiem, Yes it can be used with sprint booster, although honestly sprint booster doesn't really make more power it just improves throttle response. If you modify your car with the right modifications to improve efficiency you will get the same effect without having to buy the sprint booster. All the sprint booster does is trick the throttle inputs from progressive to a more linear feel. It works, but is is a bit gimmicky in my opinion.
All our modifications are compatible with other modifications so you never have to worry about compatibility. That is why we design them to be direct OEM replacements.

besides higher redline what else is modified?
Is the transmission learning mode disabled? ( would be really nice to eliminate the shift lag)
what is done with the AF ratio, timing etc?
does this ecu modify Open loop mode only or both Closed and Open?
do you need specific for the car AF ratios to be sent in or is the tune generic, same for all adjustment?

Yes, of course it changes all that just as any performance software upgrade, no additional info necessary. Stage 2 does cost additional (roughly $100-150 extra depending on the car). To be honest though, you do not really need 6400rpm; the stock power band starts to peak in the mid 5000s anyways so really there is no purpose revving that high unless you have upgraded cams.
The transmission lag is not disabled but you can easily reset your ECU via pedal reset which normally cures that lag. A performance crank pulley helps with shifting smoothness & speed as well but other then that there really isn't much you can do. You have to remember it is still the old 722.6 benz 5spd. You can't turn it into a sequential transmission so you just have to live with what you got.
Easy, because other tuners like to rob their customers blind. Just because you have a car with a 3-pointed start (and 3 letter suffix) tuners think that is a legitimate reason to rip them off. Not only do I find it bad practice, but its flat out immoral & unethical in my opinion, which is why AMS aims to provide performance products at a fraction of the cost of other tuners. Its not about the money its about the principle.
Software is especially a controversial upgrade b/c they rarely dyno as much as they should in the real world. Realistically you won't get more than 10-15HP for most NA applications on a real dyno, and even so that is usually on a modified vehicle. On a stock car, they sometimes don't even that much power at all. I've never seen any tuners software live up 100% to their claims in all my years of modding, so just take all ECU claims with a grain of salt and stick to the more substantial mods first then do ECU last to "complete" the car.
My honest advice is do software last, most people try to do it first but it isn't nearly as good as Headers, pulley, or high flow cats in terms of its real world performance per $$ .
Our stage 2 performance package (headers + pulley) & high flow 2nd cats will unlock roughly 80% of all the power you can unlock out of these motors NA. The rest will be from little stuff like Software, K&Ns, and etc. Its rare you will see this level of honesty from a tuner, but I believe honesty is the best policy, wouldn't want to give false hope or overly optimistic expectations. If you have the pulley, headers & cats already then do software it will actually provide decent significant gains, otherwise save your money for more substantial mods that you can feel more.

I want the stage 2 badly, as you know. Just trying to get my suspension done first.
Handling before MORE speed sounds smart to me.....
Thanks again for your response.
