Engine cuts out as Ve table hands over to boost Ve table seems to cut out as boost rises to 3.5-psi i have tried everything i can think of so i hope someone can help with this problem, the maf table is tuned and works fine threw the full boost curve but i am exceeding the max limits of the maf sensor thats why i need dynamic Ve working properly so i can move to SD only

Where did you come up with the units in the boost VE table? Try copying your 105 Kpa from the base VE into your boost VE and you'll see what I mean.

Also, in your logs you can see the IDC drop to single digits when you go into boost. It's running itself out of fuel because the boost VE units are completely wrong.

This is how it happened:

Units can be changed on the main VE, but not on boost VE. Boost VE is always only ever in Percent (%). If the main VE has been changed to something stupid like Number (), and the person doesn't realize that, it looks like the tables are the same.

Change the main VE back to Percent and then compare them.
