that's not possible as the EAT(gearbox)) ECU is not EEPROM type, though an engine ECU(ECM) remap would help that too cos the EAT ECU has an addaptive strategy to ECM inputs throug CAN.
so if you want better performance get a ECM remap...what you can do to improve things is to get a working V8 EAT ECU and swap with yours...it's simple plug and play...this will improve things
also put new oil and filter if they are old

Oil change will be later in year, after next engine oil change.
Very interesting.
V8 gearbox ECU.
What advantages does that give?
Thanks

Ashcroft transmissions do a fully user programmable ECU for the ZF4HP22/24 auto box.

Except the required torque reduction on shift may not be correct which will knacker the box.

a friend of mine has over 100k km with V8 gearbox ECU on Td5 without any probs... i'd never recommend something untested or destructive to a fellow D2 owner believe me... the two ECU(engine and gearbox) will 'optimise' each other through CAN... that's why they have addaptive strategy

if you mean the "compushift" that's a completely different story, it has nothing to do with this thread

If I fit a V8 gearbox ECU in my td5, what changes will I expect? will it change sooner? i.e. at lower revs, will stay in the gear longer and not cick down under laod? i.e. Towing up hill? Thank you.

I've learned a lot since this thread and the conclusion is that it's a lottery cos there are many V8 TCU versions and the vehicle's behavior depends much on which V8 TCU was fitted + what kind of engine it has (Eu2 or Eu3) + if it was remapped or not + tyre sizes + weight + driving style, etc, ... i've seen cases when the owner was very pleased with the result(the one i mentioned in this thread), others didnt notice much difference and others said it's worst but as i dont have an auto i didnt make a deep research which TCU is better and for which conditions so i can't recommend anything certain, you'll have to try yourself.... the only certain thing is: if you want the best without specific power tuning you need std dimension tyres, that's a fact.

Cheers, i can only play with the toys that I have. So I will try, if it works, great, if not, no loss as it only cost £30 on ebay. Not a bank breaker. My tyres though, are like new and it would be costly to replace. So will have to live with them.
The other thread you sent over to me sounds interesting where you manually lock the TC by bypassing the TCU and wring a relay and switch in. I might give that a go if my V8 TCU does not work. Thank you for you adives.
