Thread: Remapping a Discovery 4

Totally agree re the 3litre TT. I would personally be quite happy with its out of the box performance. If i had bought a 3.6v8 diesel l322 i wouldn't have bothered remapping it i don't reckon, although as a dealer i kind of 'have to' remap my own vehicle don't i? 😈

Certainly worth flashing the td6 , i towed a rusty old D1 25km today and boy it is a fantastic engine that M57...😃

Yeah, I agree, the power / torque of the standard vehicle is excellent, the improvement was a side benefit, the main reason I had mine done was to defeat EGR. Fuel economy gains are a widely commented on upside of shutting off the EGR so I was a bit surprised to have gone backward, but as I said it is what it is.

Aww I don't know. You don't always need it but at times it's nice to have. Mine-admittedly a RRS with 6 speed auto is now noticeably lag free. Using less fuel- just. But has same sort of get up and go that I so loved in the TDV8.

Any recommendations for where in Sydney i can get the TDV6 remapped?

For those with the 3.0 it looks as if BAS in the UK are close to having an OBD mappable ECU. DISCO3.CO.UK - View topic - Discovery 4 3.0L Remap Tuning with control via OBD

I'd also be interested in who in Sydney (or Newcastle) can remap my SDV6. Keen to defeat EGR before things get messy.

Interesting video from Roo Systems on the RRS 3.0 - curious, all the literature published by LR quote a torque figure of 600nm on the 3 litre, yet according to Roo Systems it doesn't get anywhere near that in standard tune. And even after remapping, it never gets above 500-odd nm. Have I missed something?

I had my previous car (RRS 3.0) remapped in 2010 just after buying it, and the increase in grunt was noticeable. But I never had it on a dyno, so have no idea of the real figures before/after.

Unless the engine is removed to be tested then the measurements are derived from wheel measurements that have been adjusted for theoretical drive-line losses using formula and are really only good for comparing before and after modifications on that particular dyno machine.
