Urs6 Auto MTM 303 Ecu/Tcu Questions

[UrS4boy]

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

Care to enlighten and humble me?

Please?

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."

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 .

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).

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

Will do,

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..

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.

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.

No such modifications are done in the trans.

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."

This would include feed back between the TCU and the ECU to modify engine timing (pull timing) and boost at the moment of a gear shift in the transmission. This would momentarily decrease horsepower and torque and, therefore, the literal impact on the auto transmission internals. Not as good as a standard but certainly a strategy to let the ZF 4HP18 live a bit longer.

IF MTM had just left the TCU alone, the way you probably did when you went Stage 1 or Stage 1+ back when, they would not have put their lovely MTM label on the TCU.

Sorry.

Normally I might agree but since MTM also modified the tranmission 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 tranmission had a better chance of surviving the changes to the ECU.

Remember this car is automatic box.I don't think MTM would upgrade the bigger Turbo on the car which shorten its life very soon.
