    So lots of people on forums said it wasn't worth remapping a 316i for such a small power gain, I just had my car remapped by Jason @ BWChiptune and have discovered that all those people could not be more wrong. Before the remap the car would judder pulling away, need lots of revs and I'd have to drop gears to stop it juddering a lot. Now with the toque boosted across the entire rev range it's way smoother, pulls away noticeably harder and can even take off with no gas at all. The juddering when you slow down in third for a turn is all but gone. Obviously a 316i is never going to fly off the line but the overall improvement in the driving experience has made this well worth the money.



    I had a pedalbox installed before the remap but now I'm going to send it back as it just seems pointless now. The car is way more fun to drive now with the remap than before just with the pedalbox.

    also worth noting that a little power from a lower powered car makes a big % difference.

    It was £250 with the dyno roll, £200 if I didn't want the dyno. It's nice to have the graph though, if you're going to do this might as well do it properly.

    The Judder Negev talks about is when the kangaroos like when your in 3rd at 10mph and you try to pull away

    After the remap you car drop the mph to 8 in 3rd now and still pull away in this gear smoothly

    It has also removed the flat spots and the rev drop problem these suffer from on pull away

    whilst that's mostly true, there is still a little bit of judder if i pull away in 3rd from 8mph. the judder feels different though, it's like the revs are stuttering rather than the car struggling to pull and it's way less than it was before.

    actually, i just found out today i have a misfiring cylinder probably because of a dying coil. being changed tomorrow, so that explains the juddering and intermittent rev dropouts i'm seeing. hopefully when they replace it tomorrow it'll be back to the strong pull i got just after the remap, will post back here.

    I seem to have this same conversation with customers about remapping normally aspirated bmw's. I say the same thing, that Jason has spent many hours into the night developing he's software and would not sell it if it didnt make an improvement.
    Jason is at the top of he's game in my own opinion and can do things with ecu's that others can't!
    I'm proud to be bwchiptune's Kent dealer as I know that every remap I do will go smoothly as long as the vehicle is good.
    Keep up the good work Jason.

    Thanks guys
    I've been tuning these low powered na 316i and 318i engines since 2003 before I had a Dyno
    The difference is enough to take 1 second off the 0-60 mph as total bmw found out all them years ago

    You mpg should also be better now
