    Default CHIPPED UK RE-MAP DAY 24/06/06 (not 56k)

    An excellent day out today at Chipped Uk in Bromsgrove
    Great to meet everyone.

    I had my 3.0 V6 CDTi re-mapped by Jayson, firstly Jason tested my car on the rollers in standard form.


    At this point I got a slap on the wrist as I had neglected to remove my CRD2 before arriving this morning and the fuel pressure was still well down(if you are considering a re-map remove your box at least 300 miles prior to having re-map work carried out as this helps Jayson get correct readings)

    It is a long process on the 3.0 engine due to the ECU having to be removed, the ECU then has to be dismantled and the e-prom chip removed.

    Stripped out ECU


    Once the chip is removed Jayson reads the code from the chip onto his laptop, this is the origional file which he sends to his programmer.

    E-prom chip in reader, connected to laptop

    The programme is re-written increasing fueling and boost, other perameters are altered to suit the increased boost and fuel map, maf and lambda settings, overboost cutout etc.

    Once the programme is rewritten(about 2 hours) it is sent back to Jayson and he then uploads the progamme to the e-prom chip, this is then tested to ensure that the 'checksum' matches the origional file(if it doesn't match Vauxhall can tell it's been modified and will void engine warranty) the e-prom is then re-fitted to the ECU and Jayson then does a quick test on car before final sealing and assembly.

    Jayson does quick test to ensure all is Ok



    Once the ECU is reassembled and re fitted to the car its back onto the rollers


    And the results are then compared to origional figures
    My Graph. Dark ble and red are after re-mapping


    I can only say big respect to Jayson for doing the car and for honouring his price of £225 for my car.
    After seeing how long and how in depth he has to go to re-map the 3.0 and 1.9 CDTi's I can understand why the cost is higher.

    Needless to say I'm very pleased with the results and the figures will improve once the car has bedded back in and fuel pressure is restored.

    On the drive home, 210 miles, the car just seemed to improve, and the graph figures really do not display how well the car performs.

    My figures with the CRD2 were excellent and to be honest I was extremely happy with the way the car performed, but now with the re-map it certainly performs just as well all through the rev range, no smoke at all and it will improve, which it seemed to have done by the time I arrived home where I used my private runway for a spirited run up to 145mph and still pulling strong.

    In conclusion, the box was excellent but there is no substitute for a proper re-map

    Great pics and write up Robbie, your smile when you got back from your test run was probably the biggest of the day, second I think was Jayson's when he got back with you! lol

    That is one very flat torque curve robbie, it must be so smooth now and just keep pulling.

    Looks like you're figures may well be down due to the fuel pressure being too low as you said. You're standard run shows the car is down about 20hp!

    I think if it is rolling roaded again after a few miles are put on it, you're figures will be back up again.

    p.s. todays date is the 24th

    Yes George, Jayson said figures were well down due to fuel pressure, but he has no control over it, it goes back up to normal after around 200 to 300 miles.

    The run home has made a big difference and it's still going to improve

    Based on standard figures of 184 Bhp and 400 lb ft, I'm going to be around the 220 Bhp and 450 lb ft once everything settles down
