I have looked and looked for a good write up on spark tuning with EfiLive. Everything says that it should be done on a dyno...which is fine. But i would like to get it close or within reason before jumping on the dyno. I have already tuned the truck pretty good fuel wise and the Ve table is almost spot on. Im running a COS3 and the mods in my sig. So if you guys can post up a good write up or give me a hand that would be great. Thanks alot.

 

its more a trial and error kinda deal.
when your AFR starts to richen up, try to add a lil timing there.

 

Best power is around 30 degrees at WOT, but dont leave consistent spark knock in the tune.

 

Ok so WOT spark timing is just hit and miss. What about part throttle? Is there anything i can log like DYNCYAIR_DMA to help me see where im at in the spark table like in VE tuning? Im new at spark tuning so ill take all the help i can get guys

 

yep.. and go to your B page under dashboard... select your wot pass and go back to your tune and it will be selected where its reading from.

 

So the DYNCLAIR_DMA.pid is used to tell me what spark timing im actually using at that given RPM, and if im using the High or Low Octane table? How do i use this to help me tune the timing? Sorry like i said im new at the spark thing

 

Also when adding spark should i be adding it to the High octane table and just subtracting 2 or 3 degrees from the Low Octane table? Do i do anything with the Optimal Timing table. Thanks

 

Can anyone answer my questions? Or add some more input for me on spark tuning?

 

Cant help you there bud, I use hptuners.

 

Add spark/timing to the High Octane table
To determine if your using the High or Low octane table log the PID GM.ASPARK
