Thread: LR D2 TD5 ECU Tune

Ha mate triumph rover spares, I think they are in Vic and Bruce Davis performance are in Sydney. I have a TRS remap and yes it made a difference but they are a bit mild for my liking and like to stick to stick boost pressures and exhaust sizes. I have a 01 td5, as you can't flash that ECU I bought a flash-able ECU from them with a new tune on it. I asked about exhaust and boost and they said not needed, well not long after I had warped manifold, I put it down to higher EGT's as tuning induces more fuel but they don't increase boost to compensate for the extra fuel. I have since upped the boost and it has been ok since. I am still chasing more power so will be talking to Bruce Davis Performance soon I think.

A warped exhaust manifold is not something I really want to deal with!

I read somewhere that if you can hear your turbo in your discovery that the exhaust manifold is leaking? I have excellent hearing and I can hear the turbo spool up when accelerating. It's pretty quiet but it's there. This is my first Disco so I am not sure what is "normal"

Welcome to the forum,
Is Tombie still around? He was on this forum and use to do a remap of the ECU with good results.
Les Richmond in Thomas town do a remap - they do not do it themselves but send the ECU out to get done - aprox 3 day turn around.
Also talk to Ritters Automotive in Burwood, if they can not help you they will point you in the right direction.

The 2004 Td5 will have a flashable ECU so you only need to have access to a Nanocom to be able to upload a tuned ECU map.

There are a number of specialists in europe who can provide tuned map files:

fwiw triumph rover spares are based in Adelaide.

cheers

Turbo spool is normal. It sounds like a squeaky belt when the manifold leaks.

Then maybe a TD5 was not the right choice because it pretty much happens to them all . You could try Ivan at Clarke Automotive (02 6024 6664) in Wodonga - I live in Alexandra and prefer to go to him for mechanical work than Melbourne. You can also get a map remotely sent to you if you have a nanocom or the like - I cant do this with my D2 as mine is a 2000 model and doesn't have a flashable ecu like yours.

My theory on the manifold warping (for what its worth) is that it is more due to the weight hanging off the manifold than other things. If you look under the bonnet of any other 4wd the turbo nearly always has a support bracket to take the weight off the manifold. In the TD5 the turbo, manifold and exhaust dont have any support and all hang off the manifold studs which puts heaps of pressure on the studs. Someone should come up with a support bracket to keep the weight off the manifold. Just my 10 cents though....

Thanks for all the comments guys. Even though I am IT savy I am not really wanting to try and modify my ECU settings with a nanacom. I would like to take it somewhere where they can tune it, on a dyno preferably. I dont like the idea of just wacking tunes on cars and hoping for the best. Also has anyone had their ECU firmware version updated when getting services? I know LR releases updates for problems they find in the ECU.. bugs etc.

In defence of the TRS tune. I also have a 2001 TD5.
This has been in the car for approximately 6 years, in this time i have done a bit of towing of a 2.5 ton trailer.
To date no problem with exhaust manifold, so i would not say that they are a cause of exhaust manifold problems, any tune could contribute to that.
