So why 2 different flashes? Can't you adjust the solenoid pressure and map in the same flash? Thanks for clearing that up.

Looks like it. So, before the numbers were tru and higher and now they are simply noise of two various runs. Before, your TCU mod didn't show up on the dyno and now they do. Before TCU mods meant MODDING the TCU and now they don't. Boy how things change.
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!!

Nothing. You can alter shift points and all types of other things in the ECU (as powerchip has). I thought that Andy was actually talking about TCO mods before but maybe he just means ECU parameters that have an affect on the tranny?

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?

Dude I really think you have a reading comprehension problem....Is English your first language ???
Huh? is it just customary to throw in the personal insult or are you just sad to see your house of cards tumble?

Other ways had also been discussed. Don't confuse what is posted here with what you hear from your boss.

Honestly? I am believing less and less that it is flashed. Again, inputs may be shifted but I do not believe that the code within the TCU has changed one bit. Adaptations may get reset, if anything. That is what I believe

EDIT - You can believe what you want....Perhaps MHP doesn't really tune the ECU ITSELF. Maybe the changes are just in the ECU as you have speculated. Either way, the way the transmission behaves after the ECU flash is very different and many users have said the same. A few have even commented that "this is the way the car SHOULD HAVE COME FROM THE FACTORY". So, we can sit here and split hairs if you want - the end result is that MHP has figured out how to greatly change the way the 7A transmission behaves - can any other tuner say the same ??

Use your head....Andy has told numerous people numerous times in public that all they have to do is send him their ECU and he will make the necessary ECU AND TCU modifications. Once the ECU goes back in the car, I assume as soon as it is powered up, the ECU communicates with the TCU and the modification is done. I would also assume that this is the case since Andy has said a few times that the TCU tune takes about 200 miles to fully adapt. Not trying to be a jerk....just pointing out the writing on the wall.
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?

You are hopeless. Lemme ask you this....do you think the ECU has anything to do with transmission line pressure and the associated increases in shift firmness/quickness ? I see what you are getting at....You wanna now say that MHP doesn't do anything to the TCU at all and all they do is mess with the ECU and the charge for "TCU TUNING" is BS and they are ripping people off. Clearly that is your belief. If so, then why are you posting here ?? If that is wha tyou believe then why debate what you claim to already know ?? Again, you are hopeless man.

Not sure why you all the sudden have to pick on the date I joined. That has very little to do with any of my experience and the many MB's I have had over the years. The number of posts on this forum doesnt make you a guru or give you aurthority over anyone else...just means you have too much time in your hands....

What Jangy is trying to say is that becasue you have not been here that long, you have not seen the problems other members have had with bogus tuners (HPS) and the associated failures. What Jangy in his infinite wisdom has failed to recognize is that the SEARCH button negates that argument as all those older posts are archived. Nice try though Jangy.

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.
Sorry if I wasn't clear.
TCU: We don't need anything from you unless you choose to send us your existing TCU. We can order a spare, flash it and then send it to you so you have zero downtime. I've done the swap 3 times now and I'm down to 1.5hrs in total; R&R instructions will be up on our soon to be revamped site soon. I called the service manager at my local dealership to give me a book quote and he's going to get back to me asap. His estimate was 2-2.5hrs tops.
ECU: We need you to send us the VIN encoded ECU already in your vehicle. You can (as I did) buy a spare ECU then have the dealer install/code it for you (under $100 for the labor to do so) and then send us your original one. You'll then have a stocker for warranty purposes later. The ECU swap is a 10 minute or under job.
Thanks
Andy

Actually, I was not isolating you. Take a look and tell me if it is merely coincidence..... Birds of a Feather......

LZH, fight the good fight, but make sure you are in it for the right reasons. That goes for Jeff as well.

I haven't claimed anythin. I've asked for some facts. I don't gain from saying any of what you are posting. There is no need for me to setup and wait for a fall when I have nothing to gain. I said it from the first and nothing has changed. I believe MHP to have the technical resources to get such things done. Where I have had an issue is in the notion that they can simply do anything blindly and with minimal time. I was never very excited about ECU tuning, since there is already enough out there that do it. Lets assume that this "test" was properly designed, SO WHAT?? You ended up with the same thing (literally here). I want to see something new and playing with ECU parameters to get play out of the tranny is not what I want. Sprintboosters cost $250.
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.

Thanks

Hang on a sec....Andy/Jeff - are you saying the dyno pull and ECU tune that was just done did NOT have the MHP tuning but just the TCU ?? So was Jeff running the Renntech tune becasue the MHP tune never loaded and the small gains were only as a result of the increased torque from the TCU tne ??
I'm confused ????
I'm confused ????
I guess this test inadvertantly displayed what a TCU flash alone can do for power on a dyno.
