I'll wait for Andy to post and clear up the procedure for how they modify the TCU through the ECU - all I know is what he has told me privately.
Jangy - as far as your comment regarding the MHP gaining nothing - well, you are simply showing your ignorance. First becasue most of the gains were under the curve, where it really matters. Second, becasue it seems now the MHP ECU tune was not even loaded and the TCU tune alone beat the previous Renntech dyno !!!! LOL - you are lost bro.

LOL Jay I hate to say it but all you do is run your mouth. You've made two 10 second passes in your CL600 and think you're some kind of God because of it? Is that the only car you've ever owned that's gone high high 10s or quicker? I sure hope not.
I would be greatly surprised if you acted the same way you do on the net in person, if so I'm sure we'll get along famously in a week and a half.

I'd say that was a smart choice. Andy is much better at rationalizing anyday.
...all I know is what he has told me privately.
My point, exactly.

Mine? Are you sure? It is a mighty slippery slope on which you tread.
First becasue most of the gains were under the curve, where it really matters.
Again, that is noise. Would you jump off a bridge if he said he modded your shoes? There were no gains!! It was all RENNTECH!

To be clear
Fact: All HP numbers are derived from TQ numbers.
Fact: Andy has stated that the dyno would not show his gains.
Fact: Andy claimed TQ gains from TCU gains alone (since ECU did not take).
My simple question is this. IF MHP is removing TQ limiting obstacles that reside in the TCU (as claimed in prior threads), why would the removal NOT be seen on a dyno? If that was a misunderstanding and it is seen on a dyno, then why are there NO power gains associated with the delimiting? You take the governor off a lawnmower and it doesn't just have more grunt. It runs stronger!!

Andy - if that is in fact the case, that's pretty impressive and would explain the torque gains. However, I'm interested to hear your thoughts about just exactly which ECU tune was dynoed if yours didn't load - had to be the previously loaded Renntech file, right ??

So to be clear, are you saying that you can mod the TCU module by modding the ECU module and having it later mod the TCU AFTER the ECU has been replaced? Can you mod the TCU or not and if so, lets see it!!
Seriously, I just don't get how you can get things so twisted in that little head of yours. Jeff already has a TCU from us, which is why his shifting is so improved (again read his comments, jrcarts, vadert's, tuningtech's etc. for more TCU commentary) his ECU flash didn't take.

Dude I really think you have a reading comprehension problem....Is English your first language ???
It has been discussed before that the TCU stays in the car. The ECU is removed and then flashed - Jeff just said the ECU is takes 2 seperate flashes. One for the ECU tuning itself and one for the TCU. Of course, once the ECU is reinstalled it then communicates with the TCU and changes how it operates. What, did you think the TCU was flashed by osmosis ???

Now I am really confused, since I was pretty specific with Andy when he first came on here to the point of literally asking for TCU photos showing that the tranny was openned. He didn't feel the need to prove anything to me and now you say it CAN be done through the ECU. Are you saying that is how MHP does it? Are you sure that works when all you have to mod is an ECU?
...and for the record, I still don't feel the need to prove anything to you.

PC can modify shift points on a 63? Show me.
TCU mods for a 63 entail line pressure changes, stall speed changes, Torque management elimination/reduction, shift quickness/firmness, heightened throttle response, etc. There are quite a few variables we manipulate.

Just keep ignoring the data/results and concentrate on getting your car back together and running as it should.

"Noise"? LMAO. We inadvertantly got to see TCU only gains on the dyno--honestly, we didn't think they'd show except for a bit of torque but I guess we were wrong. At least we'll admit said facts, and again, I find it funny you're trying to spin this situation into a failure. We just proved that we can make more power than Renntech with a TCU flash alone.
WOW, a WHOPPING 1% increase with your mod. Let me remember that one. It is noise, Andy. That low of gains from a straight mod is shameful. At least before, you claimed that the benefits of the TCU couldn't be seen by dyno and that you were able to match or slightly beat RT's ECU tune. Now, you say that those "gains" are from a mod that costs money? So, are you saying that this is the first time you ever modded just TCU in a 63?
Jeff, jrcarts, vadert's, tuningtech's etc. for more TCU commentary.

That's it? Only your homeys? Why not some feedback from a MEMBER here that is believed?
If you want commentary about my tunes, please contact my father, mother, brother, sister, etc.

Yep all 63 TCU tuning is done via the ECU. When I first came on this site I posted that you needed to remove the TCU from the valvebody of the 7A to do a TCU on a 63 for a reason. The fact that NO ONE called me out on that told me a lot about where other tuners were with 63 ECU/TCUs.

No I don't, but I think the ECU / TCU need to be on the car for this to go. What you are talking about would simply be ECU parameters. For the 1000th time, this is not a new thing. If they are modding the ECU, then it is an ECU mod. The same way that an ECU mod can control throttle position, it can control some parameters in the tranny. That does not mean it is any more of a TCU mod than it is a TB mod.

Show you? I'm sensing a little hostility, but I'll let it pass since I'm not looking for a fight. I only meant that I thought you actually flash the TCU directly.

Now, you state that all one has to do is send in their ECU for a ECU AND TCU mod. We'll see if that is even possible, much less true. As has been stated many times before, many of the parameters within the ECU can have an effect on how other modules react. And yes, it takes a few hundred miles (closer to 500) for enough adaptation data to get stored for crisper communication but what does that have to do with changing the actual code on the TCU?
ps--we severely reduce adaptive learning, to the point it's nearly irrelevant.

Huh? have you lost it now? Isn't the tuning done through the ECU on the 63 or not? Take your time and come up with a good one. This one may sting just a bit.

So what? I am not the one that wants it gone. Moe does. I like adaptive, but then again I like myMB.

From this thread: https://mbworld.org/forums/showpost....&postcount=449
No flames intended, but clarification would be nice. Before, the TCU had to be physically flashed (via new unit or sending in your factory one), now it is all done through the ECU? Please detail the process for each car or tranny.

As for the quoted post above, do you have any idea how many other vendors with 63 tuning of their own called me out on that? LOL, exactly Zero.
Members/customers that PM'd me for more info on our 63 tuning back then were told about the ECU doing everything.
It's a shady business, we knew that coming in, and we still underestimated what some will do in an attempt to copy our tuning.

This is actually a pretty good question. Why did the A/F ratio change if the MHP ECU flash didn't take?
