"So even now after I upgraded firmware successfully I think the instructions are very confusing, but at least I made it." You're very lucky to have managed to do it since the ST10 Flasher software is very "flakey" and sometimes takes 100's of attempts to work! The problem seems t...

Raychem 20awg triple core screened cable 55A1131-20-0/2/9-9 white outer sheath with 3 cores of twisted 20awg spec55 wires, red black white, ideal for hall effect crank and cam sensors for making looms. Brand new, £5/m PM me for ordering.

I could send you my map and you could look at the settings?

All sorted now, the problem was the missing wire from the STC pin 25 that should be paralleled with the Pedal Pot 2 signal and go off to the ECU Ana1. (missing from the wiring diagram)

Thanks,

Martin

I dont know what the turbo is except its a garrett, looks like V-band attachment to the manifold. Its physically a lot bigger than the likes of a TD05 on a Subaru! Obvio...

Yes, it works brilliantly well once Steve Greenald showed me how to set it up. I can start my BMW from the button with no throttle from stone cold, go away and leave it to warm up. The idle speed is perfectly well controlled throughout the process and its perfect. All done by the ignition advance/re...

Yes, confirmed it was moving around 1cm do the conclusion was that either the valve curtain area was too small or that there was a problem with the manifold as the waste gate aperture flange was sitting on top of 2 of the 5 primary pipes in the merge collector, maybe the exhaust from the other 3 pip...

We wired out the Mac control valve to eliminate the electronics, piped up the waste gate directly from boost pressure and even with the very weak spring it still wanted to boost to the moon!
