It was in auto trans mode, but every spark correction for any trans function was zeroed out.

I have since added the VSS and changed the bin to reflect a manual trans. I'm thinking this might take...

Went back through Tiny Tuner again. Every single correction table is zeroed out. Can't find it.

PCM does not have control of the transmission.

Wired up a VSS last night. I figure it can't hurt anything.

Just made a few changes there for good measure. Really don't think that is it though. Should be good there either way as I will have a speed sensor in for the next outing.

I've been through the Tiny Tuner bit. Every spark advance or retard table has been disabled. I know that the spark limit is set low. I have done that recently as to attempt to mask the problem but...

I just ran across some files from a former V6 guy that I had stashed away. Never noticed before but it did the same thing in his car. Pulls 8* at 6,500 in one run and 8* at 5,750 in another run.
...

Still having an issue with timing. I'm beyond stumped. Doesn't do it every run, but it pulls 6-7* of timing in high gear. Been doing it for a while, and I am out of solutions. No KR.

Scan and...

No codes. Signal is dropping on the TPS, MAP and MAF. At some points the commanded AFR even jumps up in the 20+ range and the timing drops to -51 and worse.

Never seen an issue like this before.

I honestly have no idea why it is pulling timing down track. I have logged a few extra things on this run.

Computer is being run as a standalone and does not have any control over the...

Would really like to see an option where we can have a scan automatically save with a date & timestamp as a filename when the scanner is stopped.

I am searching from two .bin files.

OS ID 16252225 1997 Camaro
OS ID 16245167 1997 Firebird

Or if there is anyone here that can convert two files from .hpt to .bin that would be helpful as...

Not forcing open loop. I am very confused withthis problem. I can't exactly explain why it is comanding AFR at certain points or why the timing goes nuts.

All the modifier tables we have...

Umm.... I did happen to ask WHY

This is by no means a stock tune. And yes, 40* of timing at idle. It likes it and I have always run it this way.

I have never experienced this problem before. The car has stuck right to the timing tables in open loop or closed loop.

I also changed every sensor on it except the O2's. Have also been through...

13.0 - 13.2, but I am N/A

How often will you be at WOT for over 25 seconds?

Dyno is out of the equation on this one. Dont have the time to get to a dyno during the week with the right resources, and we race pretty much every weekend.

Russ,

I would like to get the MAF dialed in on the race car. How do I go about doing this since I cannot take the car out and log any street miles. I am limited to my driveway and the little bit...

I had an issue when I first put a cam in our car where I could not get the knock to go away, even down to 18* total timing instead of up around 25*. Went from an Autolite 606 gapped at .048 to an...

Try gapping those at .040 instead. Should cool the spark and help with your knock issue.

I can tell you guys it is not a cam install, gearing, plugs, or wires issue.

Cannot speak for Lance, but in my car it pulls hard all the way through every gear. It is still pulling hard all the...

Can the stock PCM run in closed loop with no MAF? I'm still running the MAF tune up quite nicely.

I'm pretty sure that Lance uses a TCI controller for his tranny as his car originally came with a 5-speed.

I tried out Lances solid timing at WOT this weekend, and it worked quite well for me. I...
