Thanks to Joe and ScottFW (and remembering to hook up my FP feed
) my MS is now running.
A short while after starting the engine I get the most bizzare "harmonic drone" from the idle valve. How do I know its the idle valve? I hear you say. Well when I changed the frequency for the PWM in the idle settings the pitch of the drone changed! I could get my car to play god save the Queen like the Renault F1 car in Top Gear.
I am using the MSPNP msq with only a few tweaks and with a little massaging of the throttle after starting the car it will settle into a fairly stable idle at ~500rpm!!? even though the fast idle is set for 1400rpm and slow for 1000.
The setup ATM is as follows:
94 1.8 de-catted, COPS, MS1 in stock case, LC-1, Owner who is ambitious but rubbish.
Anyone have any ideas?
P.S. How do I post my logs as attachments?
EDIT: I think I may have found the problem, I have the flyback diode installed on my tip120 like Joe and my PWM frequency is 26 and Joe's is set at 62. Do the MSPNPs have the flyback installed?
I Will load up Joe's stable idle settings tonight and see if that cures it. Whilst I'm there I think I'll also have a go at loading up 10g. No point in tuning up the old firmware when I know I'm going to upgrade and have to do it all over again.
