MSD 6010 users with a Carb Hey Guys.
I have been using the chips in my MSD 6LS 6010 until now...
I want to custom tune it. IF you can post up your MSD graph that would be awesome.
I wanted to see what you guys are running for
intial and total Timing and settings for M.A.P.
Also... try to list out the size engine and and basic mods
For example
Engine size...LS3 418
Heads........ AFR
compression.. 10.5 to 1
Intake........ Victor JR.
Carb.......... Holley AED 780 DP
Tranny....... TH350
Stall.......... 3500
Gear.......... 3.36
Weight....... 3050 w/o driver 3260 with driver

i wasnt sure if you could use the map graph and rpm, so i zero'ed out the rpm one and used the map graph-i started out finding my idle psia, which was around 6-7(around 13" of vacume)-i use a 2 bar map sensor because of boost, so a 0-30 graph
i start out around 30 degs for start, at idle it goes to around 34, as psia goes down(hi vacume), i ramp up a little more, then under power i keep dropping, down to around 20-22 degs under boost-i drove around with the 3 big dials on the laptop, gave me a better idea what was happening, where i could set the timing-still playing around with the newer stroker motor, not sure where i'll end up

i have a D1SC Procharger, the vette setup, because i used a comp vette front acc drive, was a good fit for my chevelle-now the motor is a 403 6.0 stroker, edel. intake and a blowthru modded carb
when i built the first motor, i was new to the LS world, tried running timing like i did on the gen 1 s/b's, man, i had the headers glowing red, lol
found out i was running about 10 degs more than an LS engine on boost needed, so on the dyno i just keep ck'ing the timing mark on the sparkplug untill i was right about to the curve on the plug, which on that engine was 22 degs-now gotta start over on the new one, but with the tracks closed prob go back to the dyno
n/a engine is a little more forgiving

Ha,ha, I can certainly relate to that. I have driven several miles with that very same chart that Russ refers to taped to my dash. I think every one who has an MSD 6010 and has tried to tune the Map curve has tape marks on their dash, LOL. You would think that MSD could set them up to read EITHER psia OR inhg.

Since an engine at full throttle has virtually no vacuum or a very small amount if, for instance, the carb is way to small, you could run without it. Back in the old days of distributors, some racers still ran vacuum advance for the simple reason that at the higher vacuum levels associated with driving around the pits, the extra advance at the leaner carb settings helped keep the plugs cleaner. Just an old guys .02 cents worth, LOL. Ron
