Default high altitude SBC-iD settings

channel 1: Set 10 gain 15 (about 7psi)
channel 2: Set 35 gain 15 (about 9.5 psi)
channel 3 aka rice cooker: set 50 gain 15 (about 15 psi)

i experimented with the auto settings a bit, but couldn't get the darn thing to stop overboosting. i had my warning set at 16psi with a -10 gain setting and it just kept building. i'm really not sure why. BTW...SBC boost gauge peaked at 17.2 before fuel cut.

it seems the flatlanders like running gains around 25-35, but that causes too much spiking up here. the altitude definately makes a difference

Thumbs up Try it out

Don't fear the gain!!! Try it you will like it! At altitude the same gain will net slower spool up because: Gain controls how fast your wastegate swings open under boost. By lowering your gain setting you are slowing spool up down even more. You can run a higher gain setting for this altitude to compensate for thinner air without worrying about spiking.
I was running 38 Gain 35 Set and have tried extremely high Gain low Set without any spiking. With VF30 I run 50 Gain 40-55 set for 14.2-16.7 PSI and really quick spool up.
I have heard some Delta dashers saying that the ECU pulls timing if it sees boost come on too quickly, the ecu doesn't think the injectors can keep up with quick boosting turbos
