still no go it goes to 2nd but not till a little throttle and after crusing in 2nd and slowing it down shifts to first, none of these action are smooth either , i've double checked all tables and it should be there it should shift to 2nd at 0 mph , any other idea's ?

The problem stems from the stift tables B and C being labled wrong in the current release :).

Make your changes to table B if you haven't already and that should get it to work for you in T/H.

ok i changed all tables to 0 even hot , 4wd lo, t/h, normal and its still is fighting gears maybe you cant do it with hp tuners , i checked the efi 2nd delete that kat posted and i even tried to change the rpm to 200 like in that file and still nothing , i know you've played with hp tuners i see all the same tables just labled diff. any other thoughts ?

That's all I do is 1->2 and 2->1 part and WOT shift speeds all set to 0 and the WOT shift RPM set to 200. Mine will still go into first when you initially put it in gear but as soon as you let off the brake it goes to second. I just keep a little throttle on it while I pull up stage so that it doesn't decide to kick back into 1st.

That's what I've done too. As soon as you start to move or touch the accelerator pedal it shifts to second.

ok so what i'm feeling is normal, do you guys get a rough downshift right before you stop also, if its a shift thats fine just dont want things tying up ?

if the shift your talkin about is a hard shift when you first start movin within the 1st 1' and when your about to stop then yes its normal, real hard shift too, thats what mine does but you just have to give it a lil throttle and it shifts right to 2nd.

Like I said if you have a problem with it wanting to drop into 1st when you get stopped at the line and start spooling all you have to do is keep enough throttle on it to have a little pressure on the trans while you are rolling to the line. I wouldn't launch it if you know it has dropped into 1st (you'll be able to tell by the stall on the converter not being higher) because as soon as you let off the brake it will slam 2nd, screwing up your pass and more importantly your trans.

thanks for the help everyone the tune is working great if i ease into it its a smooth shift to secound just as i hit the throttle a little rpm and it stays in sec. , i cant wait to go to the track:D this thing launches like a mutha , even at 20 psi no hop or tire spin seams a little high though like the speed but dont want to break something , once again thanks everyone
