Bringing back from the dead...I have an MSD 6012 on an LY6 but same concept. I had been running around with 20* at idle and up to 3000. I just changed that to 28* and it runs ALOT cooler idling and driving around, where it would head to 215 degrees before slowly now it doesnt seem to want to get past 180 degrees. Im not using vacuum advance with the map sensor.

Yea old post..
Running an l92, i have less timing down there, i will try to come up a bit. thanks for the tip there Hank.. I am not running vacuum advance.. i have it there ready to go, but not sure how to do that.. if anyone knows let me know.. I dont want to become an expert just need a startoff point... Do you add the number to the static timing number in the program? the vacuum is of course measured in pressure so i am not sure where to put the curve in relation to the other curve.. To tell on myself, even back in the day with real vacuum advance, i was never good at curving the dist.. who has a system that is working? I have an l92 with a bunch of cam, manual trans, 68 camaro, headers, AED carb. car is running pretty good now, but i know there is more there.. especially drivability.

I have the same question as schary, just having a hard time wrapping my head around this. Also I found the conversion of psia to HgV and was hoping someone out there that understands this better then I could tell me if this looks correct? If I am wrong, I will delete this pic, but I like to look at things versus reading and getting lost in the text.

I've posted mine here before, and now again:

Yup, that's a good visual. My '6010 has 12 from max vacuum (0.0 PSIA) down to about 14" vacuum (9.0 PSIA), from there, it ramps down to 0 at WOT...

s10xgn thank you.. but what is the static timing you have.. do you add this map timing to it and how.. that is the thing i am trying to figure.. if i brought the timing up to 28 at idle like hank is doing and set the map where you have it.. is it too much?

Here is what I understand from searching through the treads, please confirm or blow up any of the thoughts below:

1) MAP timing is added to static timing settings of the box
2) More vacuum is produced by the motor at idle or cruise
3) In the example S10xGN posted, he is adding 12 degrees of timing for any situation that the motor pulls more then 14" of vacuum
4) if S10xGN stands on the loud pedal (WOT) vacuum is reduced to close to 0" and MAP timing is pulled out.
5) if box timing was set at 32 deg @ 2,500 RPM, cruising down the road at 2,500 rpm, pulling more then 14" of vacuum. Total timing the engine was see is 32 +12 = 44 degs total

Am I getting any closer to understanding this?

You got it!

I had to go back through my attachments to find this (older) graph and seeing it makes me unsure of what curve I have now. Time to hook up the 'puter and have a look...

thanks S10xGN for the confirmation, I am feeling a lot better about this piece of the puzzle.

the more MAP and RPM timing tables folks post...the more we'll have to work from. I'll be adding mine soon.

Thanks s10.. did a mild version of what you have there...
10 degrees from 0 to 7 on the map then ramping down
29 degrees timing on the other chart.. 23 at idle 29 at 2000...
car is running really good and really fast and responsive. dont want to push it yet.. still getting the car used to the road.. but the MAP made a really good difference with the response and manners of the car.. i may creep up timing but thanks for getting me started..

I'm amazed at how much timing folks are dialing in for idle.

No Map sensor on my Trickflow 220 heads, Vindicator on 109LSA cam, Lq9.

will be testing on the track soon.

Current settings:
0rpm - 10*
200 - 15*
600 - 19*
1100 - 24*
2700rpm - 34* (Flat all the way to 7200rpm)

91 octane around 11.1:1 SCR

What would you guys suggest for an LS1 with LS6 heads, MS3 cam, Vic JR and an 850 holley DP running e85? With E85 running around 100 octane and the cooling effect it has on combustion chamber temps, my guess is the motor would enjoy quite a bit of timing.

I have a 408 in my fox and I set the timing to 15* for cranking and idle its set to 30* for full throttle at 1100 rpm just for a start. Its a pure race care and havent tested it on the track yet but it idles great now and doesnt struggle to start.

I need to get on the dyno to see where the air/fuel is.

I vote sticky as well. I have searched all over the net and this is about the only thread Ive found with some good input.

What spark plug gap are you guys running with carb'd ls1's...
I am having a big high speed mis-fire issue right now. Engine won't go over 6,200 rpm.
