    I know a long time back a guy on the continent somewhere was mapping the ECU for these, what developments have their been while I've been away? Specifically would it be mappable for an injector change. Not massive change , for something that would comfortably run 260 BHP say.

    Doesn't Martin Faulks do these? I'll tag him on FB.

    Yes, mine was done by Henk (Fastchip.nl) current power 268bhp / 485nm. I had a Ecu from a guy in France (LC Developement, I think it was called), with this one I had 286bhp but less torque and the spark plugs where always wet.
    I have a Techniprofile Cam, injectors, FMIC, forged Pistons (but for this power, i think you can leave the OE ones) and some other bits.

    I can re-map them now, however the rolling road I have in work is limited to ~250bhp and she doesn't like being pushed to that limit really (Research dyno), I can reflash your ecu with one of the off the shelf files you find on ebay with maybe a few tweaks to compensate for your mods?

    That's good to know, the engine was rebuilt with forged pistons in the previous owners tenure, its got some good bits on it- Cam, head, TIG welded inlet, T35 blower, big front mount intercooler but the fueling set up must be very restrictive as its running standard injectors. If I fit bigger injectors obviously it will need a major re-tweek to compensate off boost.

    I would be tempted to feck the original ecu off and go for a standalone unit mate. It will be loads better.

    Haven't got standalone money I'm afraid, can't justify it on a car that I paid very little for .

    You should be able to get megasquirt or microsquirt up and running for less than £500 if you get your hands mucky. I cant imagine the map resolution will be very good on the original ecu.

    As mentioned the resolution is poor on stock ecu standalone/megasquirt would be much better. Are you running standard ecu (standard maps) if so I would imagine your fueling/timing will be way off with those mods. Let me know if want me to do a basic safe remap based on the bigger injectors.
