Thread: Discovery 2 transmission remap

It sure is a time sink, but an educational one!

Trying to free up some time before November as I am curious to see if the ROM is unprotected or not.

Hmmmm...

I'd be very surprised if that was out of a TD5 .

The reason I ask is because I think once before someone told me they had that revision TCU in a TD5, but I'm pretty sure it shouldn't be.

I did however only have a very quick squiz as I'd have to start over with it as it's different to every other TCU I've bought and "decoded".

I'll have a better look as time permits.

Very interesting, I regret not making a copy of the eBay listing like I normally do.

I'll look around in case I did copy it, but in the meantime, here's a photo of that same TCU from eBay's image cache.

Another one for your repository of ROMs.

EDIT:

According to Black Box Solutions, the GS8.87.0 was fitted to all automatic variants of the Discovery 2. The GS8.87.1 was fitted to the Petrol P38 from 1999 onwards.

More to think about and research.

Yeah, all those numbers line up with the revision numbers in the .bin.

That TCU should be for the low output 4.0 V8.

The 8.87.1 will not work with a D2 and vice versa.

Based on the LR p/n UHC100350 that TCU was factory fitted to D2 with "low compression GCC V8 Petrol" engine (what ever that GCC means) ... you can see all the p/n by opening the + links here Genuine Ecu-gearbox & Transfer Box (automatic Transmission) For Land Rover Discovery 2 1998 - 2004 Classic | Jaguar Land Rover Classic Parts and here Genuine Ecu-gearbox & Transfer Box ((+)cdn/mex/usa,automatic Transmission,lhd,v8 Petrol) For Land Rover Discovery 2 1998 - 2004 Classic | Jaguar Land Rover Classic Parts

GCC means "Gulf Cooperation Council".

The Low compression version of the V8 4.0l engine was delivered ONLY to GCC countries and Australia.

As you mentioned, the TCU listed above is for the lower power V8, so it's the correct unit for V8s in Australia and the gulf.

I was pretty sure it was a V8 controller but had to check.

I have a td5 disco2 that would benefit from a gearbox remap but not being to tech savvy will this get off the ground

I guess it already is "off the ground".

However I'm very time poor at the moment and it doesn't look like that's going to change soon.

Also... I spent that much time on Dev work I got pretty well cooked, and couldn't really face getting back into it.

So I don't have a website and I don't advertise, as that would suggest I can quickly supply a tune!

If you send me a PM though we can talk it through..(when you have enough posts).
