for shifts<br />
<br />
mph and rpm both have to be met in order to make a shift true....if rpm isnt being met then compare shift mph vs actual mph.. raise mph till it matches the rpm<br />

with 8 psi you can easily get away with 1degree of timing deduct per psi...so figure what your motor NA would normally see and start removing timing from there. on 8psi you can run 20* timing easily with a AFR of 12.0

there is no way I can figure what my engine timing likeness is at N/A state....she was born boosted.

I try to think engines are like humans. they all flesh and bones, but tend to act different when exposed to various situations. So do engines.

I think that if I can find a way to calculate my exact dynamic compression ratio, I'll be closer to pinpoint a generic number for the timing, and then work it up and down on my specific weather situations and other variable conditions.

To do that will you guys need my exact specs, or can you give general advice....like one size fits all?

thank you guys for all the advice.

Like it was mentioned, increase timing until there is a hint of knock, then back it down; or add some real fuel that engine and quit playing around with pump gas.

don't forget the OS of the pcm, engine noise, timing curve, power curve, engine flow, all the variables not mentioned play a part in maybe timing.

Plus some motors just hate timing

I'll play some with timing next track and tune day.

Dumb me right, like race fuel grows on trees. Pump gas is all I have now and I want it to run nice and efficient, not all out strong.

I just bought the TurboSmart e-Boost2, so when that arrives I'll test if the engine can handle maybe 9-10 PSI with pump gas and water injection. Will not be the most efficient way, but probably give more fun at the street than 7-8 psi. You can always pour some race fuel, more timing and more boost the easy way, but 89-91 octane 12 sec truck is a nice street toy.

Farmtruc, I have OS safe strategies on line, is a street truck, not a race truck.

i see your scanning in km/h . In the file are you setting shift points by mph or km/h?

[George C]

theres ways but only true way is to have at it.
