Took a log of my daughters 05 Rumble bee, truck is bone stock, except former owner played with the tune.....truck still has exhaust manifolds, oem air cleaner with a stock filter. has a cat back system and duals after the muffler.

the tune has a "ghost Idle" thing going on

Couple things I I'm trying to figure out,

1) before it's even running the LTFTB1 is 25.8 and remains 10% higher then B2 all the way till about 1 min in the log.... Not sure what's going on there any idea's
2) Roughly at 2.30 in to the log, it's running WOT , spark is 25.5* MAP is 96.1, when you cross reference those values against the WOT spark table, the table says it should be @ 27* what Modifier should I be looking at to get back that 1.5* loss,

7691 tune as of 7-9 modifed heavy idle.hpt
7691 7-10 short drive (7-9-22 tune).hpl
