Vats and egr are disabled, I double checked to make sure. Without a MAF present it can't get a read on airflow and shuts down.
Damn shame I didn't travel with my tuning laptop so I cannot send you my segment swapped P01 tune. Fortunately I do have HP Tuners on this unit. The following is from memory...
Do this:
Or do this and it will default to SD:

Thanks so much Mike!!! I'll go in and change this stuff, rewrite and test tomorrow.
Awesome!! I've had the Holley EFI StealthRam (HP EFI) on a SBC since 2013 and absolutely love it! Recall having the same type of reaction on first startup!! Nice work!
I kinda miss my old stealthram setup, would've never went LS if the 355 wouldn't have died!
Alright, got the tune refreshed and saved. I'll give it a try in the morning...preferably when the neighbors are sleeping! Nothing like waking up on a Saturday morning to an open header, cammed motor lol!!!
Reading up now about putting the O2's into open loop while getting the fuel trims right. I've already added 10% in the table. I'd much rather have it rich, then back it off.
If you have difficulty you can just command it into Open Loop through the Special Function Controls tool in the Scanner.
