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:
http://www.megamanual.com/ms2/ign_timing.htm

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 ...

i just checked that out and that's pretty cool. I'll use it as a base like you said (timing).

on the dual table it started making sense, for a bit i thought i could use 2 tables to expand the 12x12 to 24x24 but after the mega manual, replies and other posts i know get the design of the dual purpose ...

i did auto tune under no load (since i only have NB O2 right now) and am looking to do the spark table and then the accel enrichments. did you have a v8 chevy by chance to see your spark curve as an example?

Okay, just to see if i'm getting this right in the megamanual, if I use single table, both injector banks (in my case of a V8, 4 inj 1 and 4 inj2 ), and if i set it to dual table then 4 inj 1 = VE table 1 and 4 inj 2 = VE table 2?

i'm guessing that in a V8 one injector naturally aspirated engine ...

Lance,

Thanks! I think I got it. I read your post and found the megamanual on it too.

The car is now able to go around the block on its own power! just need to replace my dying alternator and off to tunesville.

MSII, MT 2.25, V3 board, using a relay for the ignition module to supply timing during crank (as suggested in the megamanual)

I have the car idling but my timing is at 15 degrees and I have have to get my trigger offset done in MT, but when it is idling MS is supplying the advance and during crank ...

Thanks both of you. I had thought there wasn't a connection for spark/ign on relay board but thankfully stand corrected.

This will make my setup easier.
