Update: MHP ECU/TCU Tuning (Throttle Blipping, etc, DONE!)








I would make it a point to post those dyno numbers ASAP Andy.
If what you are saying is true, we really would be entering a whole new era of tuning.
I just keep sitting here staring at the screen. Over a thou Trq TO THE WHEELS??
I am just gonna keep checking for those dynos sheets. You want respect......those dynos are legit...you've got it from me.
From one businessman to another, you'll officially have people on board (not all of course) , but you gotta post those charts brotha.
As soon as I get the graph it's going to be posted. I want it up asap as well.
Again we left over 100rwtq on the table in the interest of driveline preservation.
The Best of Mercedes & AMG
everyone here knows my feelings on dynos, especially dynojets, so please forgive me for being anxious for real performance data.
Thanks
Andy
One of the hardest things to achieve on the V12tt platform car is a TQ reading when using a Dynojet. Its damn near impossible unless you are using the optical pickup. What happens is often time the operator will use the Dynojet TQ conversion from MPH. This figure is HIGHLY inaccurate. I have a seen my own TQ using this method calculated at 950rwtq and a CL65 at 1000rwtq+ As much as Id like to think i made that much TQ
its just an incorrect calculation as my car has made only 712rwtq with a proper tach lead. I find your numbers abnormally high, especially relative to the amount of boost you are running. There are "dyno anomolies" that happen from time to time. Heres one example:Lou Fishgold had an S600 that dynoed and abnormally high 549rwhp and mph calculated 823rwtq Now if you took that at face value you would think this was a freakin monster, but at the track in cold weather it only ran:
1/4 Mile ET: 11.501
1/4 Mile MPH: 119.510
1/8 Mile ET: 7.386
1/8 Mile MPH: 94.930
0-60 Foot ET: 1.670
Now to put things into perspective, my car when dynoed with ice puts down 555rwhp and 712rwtq and runs 10.99 @ 125.67
I am not questioning your numbers just that they are waaaay out of the norm for this platform. Below is the dyno of the S600 :

don't get me wrong I'm not hating just questioningEDIT - This is not to say that MHP's tuning is going to grenade driveline components. In my discussions with Andy, he has assured me that blowing stuff up is not good for anyone and a quick way to put them out of business. He has also stressed that they know the limits of the driveline and will not do anything to intentionally harm it unless the customer specifically asks for it (like the S65 customer).
However, making comments in any online forum that display the intent to modify your vehicle in such a way that it will damage it, and then trying to get it warrantied could put oneself into a litigious situation.
OK, I'll step off the soapbox...

Andy, I prefer that your numbers are correct and you overcome Jay's experience.

TQ and rpm was a ***** to read on my 63 as well, however we spliced the wires apart and did what we had to do.

Andy if they used a normal tach pick-up for the 65 the torque numbers will be skewed. The only accurate way on a dynojet to do a 65 is with an optical pick-up. As far as doing the 09's, the shop were I dyno has done an 09 with a carlsson tune and one with a Renntech tune. They did not make anywhere near 690 rwhp .

One more question, again, I'm no expert on anything, but I have owned a few turbo cars in my day, but never an M-B, what exactly are you manipulating to get these hp and torque gains? I would assume huge amounts of boost and keep the waste gate closed longer? With my experiences with turbos the heat they genrate is eventually what ends up killing the performance, is the stock inter cooler going to be able to handle the heat generated by it and the boost? Have you guys even though about that yet?
