    So are you suggesting that in my case a well proven and successful "generic" map would most likely give better results than a "custom" one? Or is it far too subjective to generalise so broadly?
    Googling "custom vs generic remap" yields inconclusive results. A lot of people saying "custom" is far better, basically following the same reasoning as me. But who are these people? And what do they know? I'm always very wary of "info" I read online. And a lot of these posts seem particularly opinionated and not founded on any real knowledge. Saying that, though, there are an awful lot of them favouring the “custom” over the “generic”.
    Then there are a handful of people who, on the face of it, seem to know what they’re on about, and are talking along the lines of, “it’s very annoying for tuners who spends months and months and lots of money developing a map for a specific engine, and then people call it generic and assume it’s sub-standard in comparison to some monkey with a dyno messing about with things he doesn’t properly understand, etc, etc”. You get the gist.
    I’ve inadvertently opened up a little can of worms here, and I’m now very unsure whether I want a “generic” or a “custom” map.

    Thoughts anyone?

    Thanks,
    Leon

    Well, every Ferrari and Lamborghini comes with a generic map on it, and the generic maps were custom when they were first made.

    Ha ha yeah good point. I suppose that muddles the boundary between the two a bit doesn’t it. They’re new cars though, I can only assume it’s different with a car that’s done 100k miles.
    I need to decide whether to go for one of the vendors (and so, very reliable) to come to my house and flash it, or take it to a rolling road somewhere and have them custom map it.
    Now surely, surely, a properly done custom map must be better than a generic. It must be. I mean I’m not just after “maximum power”. With a custom map I’d get to, at least maybe only a little bit, tailor it to how I want it. A generic flash definitely doesn’t give me that freedom. So how does this sound for reasoning: are the risks of the “custom place” doing a bad job worth the rewards of the potentially better map? This is a question I’m having great difficulty in answering.

    Hiya,

    Just had my 2004 E46 330ci done, was 229bhp pre dyno and just shy of 245bhp post remap. It was done in Ripley Derbyshire (Jct 29 M1) and cost £186. They were very friendly and a cracking job, would recommend.

    You are correct in assuming a proper live remap will give better results. The problem is that just because it goes on a rolling road doesn't mean it's a custom live map. It's probably a generic remap with a rolling road printout.

    A proper live remap takes the best part of a Day to do and costs around £800-£1k. This might give an extra 1 or 2 bhp but when compared to a well made generic map, it's just not worth it unless you are racing.

    Best to look for someone who does a specific map for a car with your mods.

    If you are really keen on a custom map for your car look at a Dastek piggyback ecu.

    Cheers guys. After reading your advice and lots of other threads on the topic, and speaking to Mike from Motech, who was very helpful, I’ve changed my mind and decided to go for a decent “generic” map which has been made specifically for the M52 with M50 mani conversion.
    However, that’s not the end of it. My car is a ’97, and Mike tells me it can’t be flashed down the diagnostics port, so now I need to find a way of getting it done the old fashioned way. It’s my daily driver too, so posting the ecu isn’t an option. Argh, it’s never ending.

    I'm pretty sure it can be done via the diag port. Send a PM to Emaps, he's been doing them for years

    I have been doing these cars for years and flashing them via the diagnostic port for years

    I was sent an independent dyno plot from a customer's car I remapped few years ago. Car had the larger inlet manifold, throttle body, induction kit, cat back exhaust and my remap
