Um, getting the VE dialed in. SETTING IT UP, in SD ain't hard at all. Getting it dialed in is another.
Just finished a SD LT1. 92 or 3. Chip car. Moates APU made it WAY easier. Had a NASTY cam in it. I'll see if I can sound clip it.
Tuning in SD is HARD on these things to get right.
The open loop tuning to run roughly the same A/F at a variety of temps.
The power enrichment from the factory is WAY outta whack.
One of the first things I do, after locking it in Ol is set the PE to the % I want versus RPM and then don't touch it.
Then set the open loop % change to A/F versus temp.
There's alotta shit to it.
And then, And then, that doesn't even bring in to mention to more radical ones that are wanna go over 100 on the VE table, and what ya gotta do to properly map those.
Ya scale the injector flow rate and Ve til ya get the table in a workable range.
Givin up too many secrets. That's all for now.

Damn good info here that flys in the face of what everyone will tell you! BUT TRUE!!! I can not even count the arguments I used to get in over this stuff on the Edit list. You have so many people telling you how you HAVE to do it and that changes everytime you turn around.


Again good info there
