E70 ECU remap

jbutterfill · 01-25-2012, 08:21 AM

Hi All

I have a 2008 E70 3.0sd and am looking to get it remapped primarily for economy rather that performance. I have spoken to various tuners such as Jason from BW chiptune and Simon from Emaps - both seem like good guys and very honest.

I just wanted to know what peoples experiences have been with getting specifically their E70 remapped - and if in hindsight they thought it was worth it. Whats the average MPG etc. Are there other tuners to consider?

I have also heard that if you get it remapped it wont really do much to the economy, but lots to performance.

I get the feeling that mappers have a generic ECU map template for each car (rather than a wholly custom map) which they then load on to the ECU and do minor tuning to make it tailored for that specific car - is this correct?

You guys in EU have considerably more options then NA flash wise for diesel. I've been running BMS JBD in my 2012 e70 35d right after the break in period at the highest power settings. All I can say that the truck eats more then in stock form as it does move faster. I'll be getting a flash from RennTech soon enough and post my review then.
