help with shift points? I have a nitrous cam 230/236 FMS and a yank 4000. N/A the car will shift with no problem but once i spray 150 it won't shift from 2nd to 3rd. I have edit and Atap. I have tried moving the mph and have tried adjusting the rpm for it to shift and i can't seem to find the correct combo. I just was wondering if anyone knows a good rpm/mph that might put me in the ball park. i have 373 in a mosier 12 bolt with 26x10x15 MT ET DRAG's. right now i have it set at 6700 rpm and 84mph. it was at 6800 and 86 i was trying to get it to shift earlier. I would like it to shift around 6800 b/c i have the rev limiter set at 7k.
anyone that has had the same problem please help.
thanks

I'm coming up with 79mph for 6700 and 80 mph for 6800.
(using a .032 tranny loss that appears to be what was in my stock pcm)
Drop the mph on down to 78 or 79 and see what happens.
The rpms you have set up will still controll it.
Because both have to be met.
If you hit the mph early, it will still wait for the rpms.

yeah i tryed the 6700 @ 78 and it still hit. matter of fact it started hitting in 1st to 2nd as well. can't figure that one out? i didn't touch 1st.
I was seeing a little better than a 300 rpm spread at nearly 400rwhp.
I've heard that a deeper tranny pan will fix that. I opened up my limiter to 6900.
Later I put in a shift kit and a deep pan.
Spraying it will put more strain on the tranny, more slippage.
And will push the tranny fluid even further to the back.
