Guy's,

has anyone got a table/ graph for the ignition timing on their 931 that they could let me have a look at. Also, do you run compensations for boost [ressure, or is this integrated into the base map?
The reason i ask is that my ECU has base setings, which you can then tailor with compensation values, for boost ect. So the timing, fuel can beset, and the ecu can then automatically shift values, depending on other parameters. I would love to compare other peoples timing maps vs mine, and see if there are any improvements i can make.
Plus, it's cheaper than dyno time!!

Thanks,

Steve

I presume you aren't looking for the factory curves. If you are I have them in FSM that I can email to you.

Rasta, that would be handy, but im should have been a bit more specific. I am looking for the ignition tables from those running a seperate ignition system, such as MS/MJ ect. Especially if they are running a little more boost than standard.
However, please forward the stock curves as it will give me a reference point to start.

Thanks,

Steve

what's your email I'll send you my map...
same as yours... distributor has no vacuum advance and no mechanical advance
base timing can be adjusted with modifiers.

This is the spark table I'm running on my turbocharged 924 NA (9.3:1 CR and 0.9 bars of boost).
