Ok,has any1 Done this?
As the Manual Conversion is a HUGE job,maybe this would be more viable
If it's a Straight swap,I'll defenitely be thinking of doing this
If there's more involved i'd really like to know:cool:

I'm interested to see if anyone has done this, would be sweet to have a TR tiptronic :bowrofl: . But i can see it being very expensive for the TR, for yours might be fairly straight forward, all in all this post was pretty useless :cool:

not Really Leigh,Still jus wondering if this has been done at all,by any1!
So if any1 has had it done,or knows of any1 that has had this done,please share it!

I've tried. http://www.aussiemagna.com/forums/showthread.php?t=6362&highlight=tiptronic

And failed. :(

Basically it appears the ECU firmware is different. Which is a real shape, because a TJ1->TH2 tiptronic is virtually the same about from some very simple wiring.

Just to clarify, the only reason it failed was because of the ECU? is this correct?

What about the BEM, did this also need to be changed? :confused:

If you managed to source the ECU and trippy from a wrecked 3.5 I can't see why it would be a problem. I know booya had a gearbox and ECU to sell at some stage from a wrecked KJ Xi Verada. Perhaps he still has it?

Thanx for the Replies guys:D
If i have to i'll have to go on the hunt for
a 4 speed tip out of a Sportz,cause it should basically
jus go straight in without any probz,thow i am more
leaning towards the 5 speed,if the ECU does'nt work well
with it,I'll go out and get a Piggy,that should fix it.
This Conversion won't be happening for a While yet,jus want to build
up the knowledge for it all:)
Thanx again Guys

Craig promise me you'll lower your car before you even think about attempting a trippy conversion lol

Yep the BEM will need to be changed in the TH's

Anything else need to be changed while were on the topic?? or just the ECU and the BEM for a TH? :confused:

i dont think it could be done for a TR. i understand the TR has a seperate ecu for the trans and the engine. 3rd gens have the trans controlledby the engine ecu so if u took the ecu with the trans from the tippy car it would run. but cant do that with the 2nd gen :cry: .

blake do u still have your original VRX springs? im not happy with my pedders and koni setup (hell stiff) but they threw out my original LS sports springs, VRX springs would be the same as my old ones.

Well to be honest, I don't know enough about how exactly the ECU works, or the differences between models of ECU. Some inside doucmentation would surely be INTERESTING reading!!! (hint hint mitsubishi, email them to me!! :badgrin: ahaha)

As for changing the BEM unit if you change your ECU - again I'm not 100% sure, although the the two are trained for each other. Again, the service manual is lacking documentation here. All it says is there is a communciation link between Pins XYZ on the two units, but fails to mention what sort of signalling, protocol or data travels via it.

It was a while ago since I looked in to this, but I think TH Smoker said something about the BEM being different.

Assuming one changed the BEM to Suit a new ECU are there any other changes that should/would be made i.e. are there any other parts that are trained for a specific ECU or BEM in order to receive the correct signals?? :confused:

as far as i can see you have too change the ECU, BEM and get your keys programed to the new ecu.................

the TH stock BEM seems to be missing some sort of relay that the TH spots(tippy) has
also theres a bit of wireing to do..........but once you know how it can be done in 1/2 hour

atm im looking at try to change or mod the servo's in the auto for bretter gear changes and then maybe i can turn up the force motor for even better changes

I hope it works, I will be staying tuned.

Per yours and drivers last thead on this subject I was hoping to follow suit into a a 4 speed tippy conversion. As far as I am concerned, a new ECU, BEM and some wiring is not a big deal. Beyond this, were probably talking huge dollars. Is it confirmed the TH 4 speed auto can be used as a 4 spped tippy??? I was hoping someone would have done it first to prove it could be done...:confused:

Sorry guys for not knowing this(Looked in the Search,came up with nothing!)
But,What's a BEM?

Forget that sh**. lol

BEM = Body electrics module.

As far as i know, most of the important electronics run though it and its usually specific for each model of car it is designed for. E.g. a series 2 TJ tippy is different to a TH 4 speed auto. As we have found out from this and previous threads.
