Disco 2 Tuning, ecu specific....

I have a 2000 reg'd td5 and I've been pottering around with it lately and managed to get myself hooked;

So far, I've fitted a straight thru centre silencer removal pipe, a panel air filter, a 4.5bar fuel pressure regulator and tweaked the wastegate a little. It's made a marked improvement and is much nicer to drive now - I'd certainly recommend doing the above if you're looking for a bit more go for not much money (the parts altogether came to about £100).

It appears my ecu is too old to remap so I'm looking for other options but it's not something I know much about, given that my ecu is too old to remap - would that mean I can't fit a solder-in chip (I can do that)?

What are my other options? I'll buy a later ecu if I have to but I'm looking for alternatives first.

speak to Mike from Dynachip, he soldered in a new map on my 1999 td5, or he can supply a later flashable ecu, programmed to your car

well, that's answered the one question - you can solder a new chip in, thanks - I'm in no rush really, just looking at my options

+1 on that.
Our 2001 td5 had a non flashable ecu. Mike swopped it for 1 he'd changed the chip on before making his visit.

Will do, what do you think to the differences made - drivability and economy?

If you want more power you need more fuel simple as that, no other way of doing it. On a long steady run you may get a touch better fuel consumption. Hoofing it around town you will use more.

yeah, I understand that, just wondered how johnlad and pawl found theirs - best case would obviously be "quicker and nicer to drive but next to no noticeable difference in fuel" or similar

Well worth the money makes the car how it should of left the factory

IMO the driveability improvement is great but the consumption difference is indistinguishable...at least i can't calculate any difference on mine

Drivability & performance are much improved - will pull from 1000 rpm now - albeit slowly - and pulls well from 1500 rpm upwards . From 1800 rpm torque is significantly better than standard.
Economy no better or worse overall than before - but I do use the extra performance regularly.
If full performance used continously, fuel consumption is visibly worse than before !
If you use the extra performance for significant durations there is a high risk of the extra heat build up warps the exhaust manifold resulting in whistling / loss of power & a variety of other problems (can also happen if you use the full performance of the standard ecu continuously).
Definitely recommended!

If by ''full performance'' you mean driving it at 4000 rpm for long i agree but otherwise a well made remap or standard map should not have the effects described by you IMO

Sierrafery, which effects that I described do you think shouldn't happen ?

i meant warped manifold or increased consumption... i have been driving it with a stage 2 remap for the last over 60k miles, i dont have the most ''civilised'' driving manner but no such problems

Sierrafery - I agree, the effects are only noticed with sustained high speed / high boost driving.
I've just started to experience warped manifold / broken exhaust stud symptoms after 3 years since a Dynachip ecu upgrade.
I don't believe the ecu upgrade is the cause, but possibly makes it easier to happen. My personal opinion is that the exhaust manifold / stud design / spec. by Land Rover is very poor & if good shouldn't generate the problem many D2 owners experience - whether "tuned" or not.
I've owned quite a few cars over many years with more than twice the horsepower of my D2 - never with exhaust manifold problems - even when tuned significantly with more than 50% more horsepower than standard.
I think my manifold problems resulted from continous high speed /high boost driving on motorways where engine temperatures were probably very high (before I installed an auxiliary water temp guage - based on reading your posts about the misleading behaviour of the standard D2 temp guage !).
The fuel consumption comment is based on the same driving behaviour - you can almost see the fuel gauge level drop while driving continuously at high speed. The D2 aerodynamics don't help at all - but I can now "cruise" effortlessly at speeds I couldn't achieve before the ecu re-map.
Conclusion 1 : The re-map is a big improvement, but the driver needs to understand the engine limitations to avoid manifold issues.
Conclusion 2 : Fuel consumption on any non aerodynamic vehicle that weighs 2.5 tons & is driven fast is not going to be good ! Not a big surprise !

The remap is brilliant and worth every penny. I have had no reliability issues and don't notice any difference in consumption but it drives like a different car.
