3) The idea that the TCU can be flashed through the ECU on new cars is not too far fetched. I recall one of the technicians that was working on my car told me that when Mercedes released a new TCU update, we (the dealer) flash it through the ECU. This means they do NOT take the TCU out for a complete flash. However, I've yet to confirm this, and will try to get a definite answer in the next couple of days.
As a result of the same experience, I found that the TCU datalogs at least temperature, and accepts programming about 3 times faster than the ECU.
I was also told that the TCU would adapt from where it was to where it needs to be in about 1 lap of Laguna Seca.

Here's another thing I've experienced with MHP and I don't hear people talking about. andy say's his price is so high because of the massive amount of time it takes to tune an ECU TCU 40hours+ if that were true how could he receive the ECU TCU on Tuesday and ship it out Wednesday

Whether or not "through the ECU" or not, I can 100% confirm that the TCU can be programmed through the same port under the dash that is used to program the ECU.
As a result of the same experience, I found that the TCU datalogs at least temperature, and accepts programming about 3 times faster than the ECU.
I was also told that the TCU would adapt from where it was to where it needs to be in about 1 lap of Laguna Seca.

By the way, are you sure that the necessary adaptations are usually complete after 1 lap only?

I wish we could get some kind of clarification from the MHP team at least on what's going on.....

I just don't think he wanted to admit this as his custom tuning is a nice sales pitch.
