Well I ran into someone at the track last night that once had the same problem with a big cam/big stall in his Camaro. As it turns out, the fix is right here:

I intend to shift at 7000RPMs. With the WOT shift speeds as they are, (51MPH 1-2, 93MPH 2-3 I shift right at 7000-7100RPMs for both (for the second log I changed the WOT shift to 52/93 and just...
Ugh.. another dissapointing night at the track. It shifts into 2nd then third a little quicker off the line now, then downshifts into 1st instead of second. I have NO IDEA what would cause this....
Thanks, I'll give all that a shot today.
As for the car, stock displacement and the heads are the bottle-neck at the moment... they're "near stock" :)
Excellent. Thanks Russ :)
I'll be at the track again on Wednesday to see how it all works out
This is the nuber that the tire hight calculator in the HPTuners software gave me. However, Russ K mentioned:
What I'm wondering is where 24.91 that Russ refers to comes from.
As for the drag...
Wow, it's actually doing what I tell it to now. Thanks Russ! I set the 4th gear TCC apply speed to 61mph at the lower end and the release speed to 55 and now I can actually cruise through town at...
244/249 .610/.613 109LSA
Should I just keep increasing the base running airflow until I see results? I left the throttle stop at 2% and let it warm up. After it was hot it idled very high until I...
I hope so.. it's got a pretty big hole in there already.. a little over 1/4" :eek:
I've made the recommended changes and still had some issues. It would idle without me holding the throttle but it was 500 rpm or so below the desired idle. I finally looked at the IAC position and...
I tried that. Even with the value over 60MPH, I still saw lockup near 45mph. Of course that was before all of Russ K's changes maybe it will work now...
Thanks guys...
To answer some of the questions: I left the 3-4 shift at 100% at 255 as to not shift into 4th at the track (that's really about the only time this car will see WOT). There is a...
I made that change as suggested by MMGT1. Updated file attached.
As mentioned above, I can't really test the changes until next wednesday at the track, as that's the only place that I can get a real...
I made the above mentioned changes, it holds an idle, but much lower than the target. It's also kind of touchy. A quick stab of the throttle and it will not find it's idle on the way back down and...
Much better. It didn't die immediately, but it does still struggle to hold it's idle. I logged the cold start. I let it idle for several seconds, gave it a little throttle, then put it in gear. A...
Hell, I get a really rich smell all the time... I had someone tune the car for me when I first built the motor and since then all I've been dealing with is the automatic trans shifts (thanks for your...
At the track I run a 26x10.0 ET Drag. On the street a 315/35/17 radial. Tire size is set at 25.69. Should I change it to 26 when I'm at the track? I kinda figured they were close enough.
Since...
When the car (99TA, LS1, 4L60E, BIG cam) is cold, it dies immediatly after startup unless I hold the throttle open. For the first minute or two, I have to "two-foot" it to keep it alive. I searched...
I never thought of that. Just assumed it would ignore the part throttle table when at WOT. I made the changes. A shame that it will be a week before I can see if it helps. I really think something...
Using Tunercat where I used to work, I found a table for my 99TA with shift MPH and lockup MPH vs engine load, but I've been unable to locate anything like that in the HPtuners software. Am I missing...
Here's the tune and the log for that pass:
I've been chasing down this problem for a year now. Immediately after launch (at WOT) it will shift to 2nd, then immediately 3rd. After a second or two it will downshift to 2nd and then continue the...
I just can't wait to get my hands on this product, and I'm sure MANY others feel the same way. Is there any chance at setting up mailing list so that us anxious buyers can recieve an email when it's...
Hey there! I'm Travis, known as Skinny on about every other forum I post on. I've known Keith through the Firebirdv6.com site for quite a while. Currently driving a cammed 99 Trans Am with tuning...
