speculation
1. the forming of a theory or conjecture without firm evidence.
"there has been widespread speculation that he plans to quit"

True but there is at least some firm evidence that MTM modified the TCU *AND* the strategy I have described to reduce the stress on the 4HP18 autobox isn't something I just made up. It is used by many luxury automobile manufacturers, typically as a means to make the shifts smoother, more luxurious and less obtrusive.

BTW I never quit.

4HP-18 can handle much bigger number of torque as long as you didn't abuse or launch it from stationary.just baby it from the first rolling and it's good to go.

Well said that man!! Babying to start of with is highly recommended and what all helmets should practise.Most Women on the other hand have no mechanical sympathy whatsoever and therefore devoid of all resposibility .

Simple way to clear this up is open both the ECU and TCU which i intend to do on sunday.

I have been recently informed that this chip set should run fine on a stock turbo.
Still a little uneasy about this but its worth a shot with a boost guage attached..

Unless you are Neo from the Matrix, you won't be able to "see" much (other than the labels, on the MTM chips, which will be very interesting, i.e. please post photos).

Will do,

Map sensor will tell more.Or get a boost gauge+wb afr and be on the safe side.

You are correct. And I never said that the transmission itself was modified. I said that "MTM also modified the transmission control unit (TCU) at the same time, I can imagine that they figured out a way to limit torque and soften the shifts so the transmission had a better chance of surviving the changes to the ECU."

I know exactly what was done in the TCU and none of what you describe applies.

Care to enlighten and humble me?

Please?

Anyone know what turbo to be using with MTM 303PS.I just found a urs4 with MTM 303 PS ECU has the RS2 turbo and exhaust manifold on that car.

Sounds about right. Find out more info Pop. Injectors?

All I have so far was this from some old MTM website listing (turbo is mentioned but the RS2 EM is not).

Inside the TCU, no pictures of the ECU as my phone ran out but it had 2 similar chips with the same hand written labels, one was mounted on a scrambler board.

Thanks for posting. Now get that battery charged on the camera so you can photoize the ECU chips. BTW scrambler board for the timing chip (top board) is pure MTM.
