[Ls1_Rulz]

hi everyone .. i don't know what is going on with this car..

camaro Z28 A4 1998

Lt's + lid + LS6 Intake + cat back (stock TB & maf )
TC 3500 2.5 STR
cam 228 / 232 .588 . 595 110 + 4 lsa

New Tr55 + MSD 8.5

see the log file and tune file.

1- there is alot of KR at idle (it's timing or something else )?
2- after hit the gas the RPM drop down to 200 / 300 and go back to 800 /900
( see the frame 2660 to 2760 )

as far as the KR it could just be a fluke, maybe a KR sensor failure
or sensitivity setting,
an overly lean/rich condition, sometimes an exhaust rattling
against the floorboard can cause this.
i saw no WBO2 data logged,
and the MAP irregularity can be resolved by removing
the in gear portion of the map.
your tune looks pretty good IMO nothing out of the ordinary or alarming.
i recall recently a guy had posted a tune with like 40* at idle. LOL
some ideas for you.

do you mean replace KR sensor ? :Eyecrazy:

how do i know if it's lean or rich without WBo2?

Yes, no wbo2
and the MAP irregularity can be resolved by removing
the in gear portion of the map.

those were some suggestions for you to think about.
i have heard the older years fbody KR sensors are funky.
as far as WBO2, there is only one way to know for sure
and that is to get one.
