Hi all,
This ones got me baffled, spent a couple of hours researching into this but can't seem to find out why this is happening, in short, my 7202 is interpolating between the high / low ignition octane maps with no knock and 100% octane level, leaning towards the low octane table.
I'm running KSMods v1.03, currently with stock ignition tables (well, Kens larger tables loaded with as close to a stock 7202 rom's timing as he could make it), here's an example EvoScan log (save to disk, rename to .csv) - http://db.tt/PcKPauHg - although I didn't log intake temp, there shouldn't have been much heat soak.
Another example, on one power run after the car had been moving non-stop for a good 60~ seconds beforehand, I logged a timing advance of 14 degrees with no knock and 100% octane at 140 load / 4700 RPM, the low octane table value for that load / RPM is 8 degrees, the high octane is 21 degrees :dizzy2:
Anyone able to shed any insight?
