    Did you have a map already put on the ecu then?
    Yeah new loom is ace. Lovely and thin and flexible too. If anyone wants a loom making PM for the guys details he was very reasonably priced compared to some I’ve seen and open to customisation.

    Ive put Houses map on for now. As it’s only running ignition at the moment I’ll probably get away with leaving it. Hopefully find some jenveys in the future then consider mapping it.

    TPS adapter loom for R1 carbs has arrived. Set up the open/closed positions in he software and took it for a spin. I can confirm the car drives a million times better now. Really responsive in the low revs and doesn’t stop pulling.

    Croft yesterday. Not been before, but very interesting and technical circuit with lots to learn. Only really felt like I was getting most of a lap right towards the afternoon session.

    Team Shonky attendees were Harvey in the Astra, House in the Nova and myself. Three started, and three finished with no breakages.

    Pit garages were a little small but fitted three OK:



    Harvey's wife on the camera snapped some good shots:







    New ECU was faultless. EPAS stopped working momentarily and spat me off circuit but luckily no damage, so I'm going to look into a permanent resistor to solder in rather than the adjustment dial that I think is playing up.

    Feedback I've received is I unsettle the car every single corner, even when trying to be smooth. I think this is down to my EPAS controller being too sensitive, all the time. To resolve this, I need to feed it a speed signal.

    Harvey kindly made me a "wheel speed sensor starter kit", consisting of 15 pulse amp, sensor, wiring and bracket. The orange amp is part number 09185826 and is wired up as follows:
    - 15 - ignition live
    - 31 - ground
    - IN1 - one of the ABS sensor wires
    - IN2 - other ABS sensor wire
    - OUT - 15 pulse speed signal to feed into EPAS



    This obviously requires an ABS ring on the CV, so I swapped out my non-ABS CV for one with a ring...



    ... only to be told it's the wrong ring, having 40+ teeth rather than the required 29. So I relieved a spare CV of it's ABS ring and swapped it onto the newly fitted one:



    I then modified a sensor carrier to fit the Nova hub



    And got it so it fits in snug on the original backplate bolt hole. Because of how it's modified, it can't physically twist into the ABS ring and eat itself, which is great if it works loose.



    Factory fit!



    I'm still feeding a rev signal from the EPAS controller box so the steering works with the ignition on and engine not running, and it appears to work exactly as desired.

    One week till I take the car to Rockingham to test it on corner one!

    I wouldn't say you unsettle the car, in as much as you throw it in and hang on for dear life as the rear tyres scream for mercy.

    This will help enormously!!

    Nice work Iain. Having been a passenger in your car i agree.

    Also no braking for turn 1.

    Why didn't you just fit a 15imp gearbox transducer instead of all that?
