Re #118, Hi Steve, there are ignition advance defaults for idle speed setting in the 9A4 ECU, my unlocked ECU has the minimum ignition idle advance set to -15 degrees (ignore the -40 degrees target advance, it is only used if there is an Air Control Valve) and an ignition-only idle control strategy:
My idle is generally stable at 1,000RPM +/-10RPM, with not a lot of variation in the ignition advance, -8.5 +/-2 degrees is the typical variability:
#121: I've just looked at my version of Easimap (R76) and the latest 992ac80b.ec2 file (with Advanced Level 1 profile), and there's no Idle Speed Status panel that I can see.
Re #123, Hi John, I just looked back through old ECU files, it looks like the feature was added to the 9A4 ECU in version 9A4ad19b on 20 Jul 2009.
Although the latest file date I have for 992ac80b is 11 Dec 2009, the actual last feature update time in the file is 7 Nov 2008 (Observed in Windows Explorer in the 'Description' Field). I don't think the 992 ECU had any later version than 992ac80b, as far as I can see, so this very useful feature is not available on the 992 unfortunately. The interesting thing is that my 2012 car had a 992 ECU loaded with 992ab94k, which has a date stamp of 24 Oct 2006 in it.
Just had feedback from my PBC at Caterham Gatwick. The engineer confirmed that a small tweek was required to the TPS to prevent the engine from hunting in a cold start. He also let me know that Easimap was used and that the base map always needs tweeking a bit.
Hopefully this just confirms all the excellent knowledge and advice provided on this thread - thanks all.
