Get this megasquirt Junkyard running

well first try and get MS to command 10 and have the light see 10, even if you have to set it to 9* fixed. That should be a good starting point

I was doing all that while some steaks were cooking so I didn't try to bring the base timing down. I was just verifying "its remotely close" :P THere is some cold advance added in there so I probably need to turn that off. It says 5.5 degrees cold advance but maybe that is ignored in fixed timing mode and simply what the computer would add if it was allowed to.

I thought it was weird that I commanded 0 degrees in my fixed timing and it ran 1 degree. When it was set at 12 degrees fixed it was commanding 13 degrees.

For anyone else interested, there are files uploaded on MSextra. Megalog viewer is free for the lite version.

I understand what you are saying with fixed at "0" and running "1".

With the 12* part...do you mean that you fixed the timing at 12 and it actually showed 13 with the timing light (meaning 1* advanced) when cranking, or that it brought the timing back to 1* while cranking with the timing light?

Both of those were fixed electronic timing per MS. Seems like it was adding 1 degree to whatever I "set" and I don't know what accounts for that.
I don't even know if the timing light changed what it said when I changed the set timing. I was in a rush and fooling around that night before dinner. Have to get back out there bit car time is short.

I thought the light was showing 18*..... when MS was set to 0 but the log showed 1. im lost. I dont even know how you would go about seeing 18* with just the light lol.

I was paying more attention to the rapidity of flashing during those starting tests then where the timing light was hitting when I changed fixed timing tables.

In other news, reflashed my corrupted firmware to 3.2.5 and she starts up and runs/revs. Timing must be off still because it wanted to backfire at first.

Good news there. best bet there is to use the trigger offset adjustment and fixed timing settings to get to 0* and let your timing table do the rest. just my $.02

[Sundance 6g72]

yeah i dont like the idea of adding your base timing to the entire table, rather I would just like to set the each value and know that that is what the timing will be.

I was never able to get a trigger angle early enough with the stock distributor to get my desired max of 45 total timing. That's the main reason I dumped the distributor and went wasted spark with a home made crank sensor.

Good to see that a firmware flash fixed your issue.

Also, you're better off to think of total timing with MS and for get the base timing + additional timing bs. MS will display the total timing based off you setting the trigger angle (physical trigger angle) to a certain number of crank degrees btdc and then then tell Ms what that number is in the trigger angle field. Then fine tune it with a timing light while slightly turning your distributor. Ideal trigger angle is 60-90 degrees before tdc. I could never get this so I said piss on it and deleted the distributor,
