T1G UP Posted January 27, 2009 Share Posted January 27, 2009 NOT a fan of the manual box in my TD5 90. Drive an auto, well DSG, everyday so i am considering putting an auto in my 90. Been offered a good deal on a disco set up.This includes the box loom ecu etc. Why can't this set up be transfered into my 90, run the td5 ecu's etc and let the box, ecu etc think it's in a disco.Would save alot of money.

BogMonster Posted January 27, 2009 Share Posted January 27, 2009 Technically I am sure it could but I think most people who have tried it have given up. Compushift from Ashcrofts is one solution, an old fashioned hydraulic box from a 300Tdi is another. The Ashcrofts have invented that wheel I think, I wouldn't be inclined to try and make it any rounder Might be worth talking to Lara on here not sure what he did but I think his souped up Td5 90 is an auto.

I like the compushift kit but i can't quite get my head around the inability to fit the factory ecu and run it as such. Quote Link to comment Share on other sites More sharing options...
BogMonster Posted January 27, 2009 Share Posted January 27, 2009 I am sure you can do it, but once you get into using the D2 electronic autobox then you need the CAN bus set up for the two ecu's (engine and autobox) to chat to each other about the weather and when they might change gear, and probably once you switch the CAN bus on, the ecu's start looking for other ecu's like the BECM, SLABS, instrument pack etc so they can chat to those as well, and then if none of those other ecu's are there it probably all panics and starts emitting bongs. Other possible problems are that the gearbox ECU probably wants to know what the vehicle road speed is, which on a D2 comes from the ABS sensors via the SLABS ECU, and you won't have any of that fitted (well not unless you REALLY want a project...) and probably other stuff I haven't thought of. But this is all assumption so hopefully somebody who knows for sure will be along However I think the fact that Ashcrofts who do it for a living have settled on an alternative solution probably suggests it is a monstrous PITA to make it work. I wonder if Dave is around to comment on this? Quote Link to comment Share on other sites More sharing options...
SteveG Posted January 27, 2009 Share Posted January 27, 2009 It's possible, but it would be a lot of effort. Talked to Dave at Ashcofts and Ian, Porny, about this a couple of months ago and conclusion was that it would be a lot less effort and potentially less costly to fit a Compushift.

BogMonster Posted January 27, 2009 Share Posted January 27, 2009 Between those two I would think they ought to know Quote Link to comment Share on other sites More sharing options...
Dave W Posted January 27, 2009 Share Posted January 27, 2009 The Ashcrofts have invented that wheel I think, Ashcrofts had little to do with inventing this particular wheel, Maddison 4x4 paid for the development and put a lot of time into the research and testing using a TD5 90 as a test bed. That is why Maddison 4x4 are the distributors of the unit. No problem with Ashcrofts selling it as part of their conversion kit but credit where credit is due in this particular case.

BogMonster Posted January 27, 2009 Share Posted January 27, 2009 Apologies to them then, I thought I read an article somewhere that said Ashcrofts developed it but credit where credit is due Quote Link to comment Share on other sites More sharing options...

Hi Dave, yes you are quite right, we have had some input with the ongoing development of the Compushift but Patrick at Maddison did the majority of the development work, I wouldn't claim otherwise.

Are there any articles on this conversion yet??? What are the benefits of being able to alter the shift pattern all the time? Quote Link to comment Share on other sites More sharing options...
ashtrans Posted January 27, 2009 Share Posted January 27, 2009 Are there any articles on this conversion yet???What are the benefits of being able to alter the shift pattern all the time? there are 2 links to mag articles at the bottom of this page : puma auto you don't need to constantly alter it, the benefits are you set it up as you want it to shift, you don't need to adjust the kickdown cable to get the best compromise as you often have to with conversions when the autobox is not designed for that vehicle with that engine. you can adjust all shift points, pressure, converter lock up and kickdown parameters very easily to make it drive 'factory' as you want it with no compromise, with the bonus of having it 'tiptronic' if you want to. you can do it hydraulically and you will save a few quid but it won't drive nearly as well, we did many hydraulic TD5 auto conversions before the compushift and they were OK but rarly perfect, the electronic compushift ones are spot on every time. sorry if this sounds like an advert but he did ask ! I honestly think they are very very good, (please delete if I have overstepped the commercial content mark) Quote Link to comment Share on other sites More sharing options...

Great article in LRM, I am looking forward to reading how it drives in the March Issue! Quote Link to comment Share on other sites More sharing options...
