Seems that SPEEDRIVEN has done it. Stand alone on an sl600 and sl65. Want to know from SPEEDRIVEN now ....can this be made for the E55?

Sure it can. I spoke to them the other day about it. I did not get the impression it has driven anywhere yet or more than around the parking lot. And they were implying a rather huge price tag.

Hulk

Obviously they put time into the R&D. With a group buy the price might be worth it.

whipplem104

It is just that it is a 6,000 dollar ecu plus R&D. Plus wiring. This is going to be a very expensive product and how big is the group buy. Maybe 5 or 6 people on a good day.
And as I said. A short vid of an engine running and driving a car and then driving a car without problems are very different.

Hulk

Obviously they would have to show how well it does.

Exactly, then you just have a bunch of pissed off consumers who spent a ton of money and their cars run like crap. If this were 5-6 years ago, a $6k ECU would have targeted the people more, but that's about half the price of what these cars are going for these days.

The issue with Mercedes tuning is when the cars are new and the owners can afford to spend the money on something like that, they hesitate because of warranty and general satisfaction with the cars current performance. When the cars drop in value and it gets to the third and fourth owners (who are generally the modding type), they don't want to spend that kind of money on an ECU. Yes, there are a few exceptions here and there, but that's the general consensus of the AMG ownership with regards to modding/tuning.

it is possible, it you look at the pictures the coilpacks are from a M113k engine

Hulk

Yup you caught that lol

Speedriven1

Yes. That's next on our agenda.

Speedriven1

Yes!!

Hulk

Have you guys tracked the car or is it like posted , just driven around the lot?

Speedriven1

It's getting baselined on the dyno this week and Monday/Tuesday.

Hulk

Post up when it gets done

Heisenberg

Wow well done, Speeddriven!

Any plans for a M157 standalone ?

Speedriven1

Yes- we discussed this on a W212 board a while back, I think. We have a guinea pig lined up- could use another one, but very few guys want to spend $10K to experiment with their cars, you know?

Speedriven1

Accurate on all counts- but going from literally zero to "all the lights work, gauges work, key works, transmission shifts, yadda yadda yadda works" in a matter of months is really something. This is a product that rivals- if not surpasses!- anything else out there in the world of motorsports ECUs, and it will very likely be well under the $20K pricetags of those offerings (which are not plug and play).

Anyway, came here to post some blogspam. Enjoy!! http://speedriven.wpengine.com/2016/...nz-mega-build/

Could be a real breakthrough. Maybe it will be able to overcome all the stock ECU limits that must be the culprit killing the 1/4 mile times on the big hp V12 MB's?

whipplem104

Not trying to take away from what you are doing and have done. I know how hard it is. There is just more to do. And I think people get over excited about things like this. The expectation of factory driveability and all systems working as factory and having a no limits ecu or tcu is just not realistic. There is a reason it takes years and millions of dollars to develop a platform for the manufacturer and then another few years of being in the market place with updates to fix issues that got through production and design.
I get people all the time with the tcu stuff that want it to be factory in every way. PLug and play with no tuning for less than a couple of thousand dollars.

Cool build Glad someone broke out the checkbook to build a mercedes racecar (besides jrcart who already had standalone ECU years ago). The turbos sticking out the hood is a bit much for me but to each his/her own. Having standalone and a 9" rear will be great for drag racing, but I will be interested how it runs for a daily where there is plenty of part throttle. The standalone ECU will take a lot of dialing in. Will this ever be a street car or is it restricted to drag racing duty? Good luck with the build!

Speedriven1

Is JRCart's standalone integrated, though? I thought that was a cut-down car? (not s***-talking, just thought that wasn't a full-weight car)

Speedriven1

Stock ECU being limited to 25 lbs. doesn't help, no.

blackbenzz

Stock E55 is limited to 17 psi so consider yourself lucky! I had to bleed off boost from the bypass valve to keep it from going into limp mode. Didn't want to go the map clamp route but now I kinda wish I had just to see what it would do at full tilt. Oh well

As far as jrcart car. It was not full interior but I don't know if the standalone was fully integrated. Is the SL gonna be full stock interior?

Speedriven1

Speedriven1

Pretty close? It will have a cage and will run a proper race seat at drag strips, but it will be full interior, probably more than full weight.
