LT8s FC3S timing maps (EMS newbie tuners and even older tuners please read)
 

i am posting this here just to let you all know the base timing maps loaded into the LT8s are slightly on the more aggressive side, if you run enough boost and lower octane fuel you WILL detonate and do damage to your motor. (note: i am not affiliated with Microtech, just here helping out fellow rotorheads)

rule of thumb i use is trim the timing back to about 15 degrees BTDC at about 15PSI(more boost will require more timing pull), increase 1 degree of timing per PSI working your way down to about 2-3PSI and blend it into the stock timing map from there, that should be a good starting point and you can fine tune from there with either an EGT or dyno with torque mapping abilities.

if a wiser tuner has a better rule of thumb starting point or wants to elaborate feel free, this is for public knowledge to prevent uneccessary failures.

i know i should have posted this a bit earlier after i figured out the cause of failure but i had been putting it off. i know it is best to start with timing but the influx of new tuners generally do not understand or focus on timing and not focusing on the timing first can result in a damaged motor.

so whats your total timing at 15psi?
what should I run: stock turbo, stock intercooler, 720 sec. inj., at 10-12psi.
also do you know about what the exhaust temp should be?

Good info!

Not everyone takes into account that it will run fine like that, or so it may seem. Until the situation is right where over-advancing can lead to damaged engine parts. Intake temps rising, gas quality, and also mechanical inconsistencies.
