Transmission ECU swap

Hi John,

I essentially remapped the maps that the EAT uses for shift points and Lock unlock of T/C based on road speed etc.

On an EU2 there is not really any reason to try and run without a MAF, if you want you could just unplug it.

The TRS ECU will not have the EGR turned off, they didn't touch it on the ones I've seen.

I'm not really sure what improvement turning that off will show if it's already physically removed.

I'm thinking not much, as the EGR map would only be letting flow into the intake under lighter throttle scenarios, but of course it doesn't do anything when blocked off, so normal engine fuelling will continue, then of course when you want more power, it's largely "turned off" by default anyway.

But it would get rid of the EGR fault you are most likely getting.

I'm not trying to talk you out of trying, but just don't expect great improvement!

Just note that a vehicle with the EGR installed and still functioning correctly, should use less fuel.

Any decent hex editor should do the job, the one I use is called "Hex edit" but it's no longer available and I couldn't find it online.

Cheers
James

i'm not getting any egr errors

what you said is about properly functioning egr being better for economy is what I have read, so by transferring my trs fuelling map to a factory no egr map must make a difference however tiny.

Plus it is a learning curve.

I have downloaded hex editor neo and another one called HxD, not opened fueling maps yet, just trying to understand the support list for the tl866ii programmer as apparently it may be possible to add in the missing chips by modifying its chip table

Long long long learning curve, can see the hex tables with binary next to each line but can't see the plain english listing of the chip which apparently can be seen once I find the right menu selections

The examples online seem to be written by people who know, for people who know already how to use the hex editors.

oh well, that's the fun of it, very satisfying once I crack it, then I will be at the level of todays 10 yr old primary school geek.

No EGR errors?

That's interesting.

What fuel tune are you running?

It'll be Something like Suhde018

MSB 101 340 in vehicle, TRS whatever level they put in tune

config sutdp007

fuel suhde022

I get no ecu tcu bcu issues /errors and after i did the shuttle valve rewire no intermittent 3 amigos (lights were blacked over when I got it)

Which pair ? Can't find em

the tcu CAN bus pair go to different numbering on the ecu end of the loom depending on V8 or Td5 engine, can't spot any difference on tcu pin out for V8 or Td5

The electrical library for both of the D2 ones shows them as the same.

In fact one reputable wrecker thought they were the same unit and was selling them as interchangeable and identical.

YEP...
*I know I've read about owners changing the TCM over from one to the other but it's not worked for me.
*On the odd occasion where I've fitted a auto trans from a TD5 to a V8 (not a simple bolt in exercise) it wouldn't shift correctly with the V8 TCM but once I fit the TD5 TCM it shifted correctly.

*I've no doubt missed something but I've not worked it out.

Some time ago when I was looking through RAVE I followed the diagram and came to the conclusion that they were wired differently between TD5 and V8...but less long ago I had another look and realised they were wired the same but the connector numbers were different between the 2, that's what confused me.

A TD5 controller in a V8 would be a thoroughly unpleasant thing, and the same the other way unless a reasonable upgrade to tuning has been made.

As regards the different autos changing differently, I can't help out there.
