    TDi remap - '98 1.9

    Hi all,
    after reading many posts about remaps for the TDi I'm ready to get this done -
    well, once the timing belt is changed i think...
    read good things about CCtuning over on TDiSport form but not seen them mentioned here.
    Seems they do 'dyno diagnostic and custom maps' at a very reasonable price.

    ['98 A4 TDi AFN engine]

    I'm after a very driveable and smooth map with low RPM torque and not peak BHP -

    any experience of good mappers for this?

    thanks in advance for info!

    Are they remapping your AFN engine or chipping it?

    I've been told many times that our ECUs (I got the same motor as you) have to be chipped as they can't be mapped through the ODB port.

    Thanks for that info Scott, I did not know this...
    I have been enquiring at a handful of companies but not been told it will need a new chip - I'll double check that.

    Most B5's need chipped, even if its generally called a remap these days.

    Any idea why a R reg 8L can be remapped?

    Any views on tunning boxes over Remaps?

    Just heard back from CCtuning - does this sound right, Scott?

    yup, 100%.

    New ECU? who said that?

    They de-solder your current chip, solder in a chip holder and push a new chip in to the holder.

    got tuning box at the mo and defo does something - how much I can't measure.

    I'm working on the assumption that remap will provide better gains, MPG and driveability but I guess this is not always the case?

    I do get flashing glow-plug light and "fuel quantity adjuster fault - intermittent" when the box is turned up
    thinking proper remap will not do this!

    ok, sorry Scott think I mis-read your post!!

    however, he says 'recodify' you say 'de-solder'... I'm a little worried about this now

    No idea but it would be interesting to know about the difference.

    I know two people with two different cars that had tunning boxes and both of them never seen or felt a difference.
    They was second hand boxes.

    He might mean the same thing, unless you can remap the ECU chip with out taking it out.

    I have all ways been told you need to remove the original chip (de-solder) and add a chip holder so you can add the new remapped chip.

    Yeah totally right buddy, had my old B5 done and that's what they did.

    He means reprogram.

    If you want to tune the car, you need to modify the mapping on the internal EEPROM (memory chip).

    Its exactly the same procedure as remapping, but older ECU's dont have an internal facility to reprogram the chip, and thus the chip needs to be removed (de-soldered) and reprogrammed externally.

    On a newer ECU, it has built in routines which allow the reprogramming to happen over the diagnostic port, and so the need to desolder the chip died out.

    Ofcourse you can if you want still desolder the chip and program it externally on a newer car, but its sort of pointless!
