Hey, I thought I would help you out and added the conditional statements for the boosted area. You meant the max the angle should retard to should be half the 100 kPa angle, correct?

blueman803 - right, the amount of retard in timing shouldn't be more that 1/2 of the ignition advance at 100 kPa ...

NP, we've all been there.

OK, so i looked at the export .vex file and it doesn't correlate to the spreadsheet, i.e. an advance of 30 kPa at 800 RPM is 31 degrees doesn't equal a similar value in the .vex files.

ronsonol,

you answered his questions better than i :!:

JonK,

Here's what ptegler was saying:

one thing i noticed about your images in the post is that it is liters/min (i believe) whereas the Megasquirt is looking at pressure kPa, so you're not quite ...

everyone,

attached is a spreadsheet i made using some assumptions and calculations from lance. below is a short description.

the benefit of this is you and play with a timing curve to see what effects like fuel octane would have on a timing table.

The first page establishes the assumptions based ...
