Who is locking there converter at WO? Where are you setting it to lockup at? What gears are you locking it in? I just realized currently mine doenst ever lock at WO, but with the new converter I believe I should be locking it at some point. I think....

 

Lock it in 3rd at the track. I'm not sure if its better to delay the lockup a little after the shift or lock it asap, that is a test and tune item.

 

Ya that is what I am trying to figure out.

 

I lock it as soon as it shifts into 3rd works great!

 

Mine is set to never lock in 2nd, and lock at 68 in 3rd, and 87 in 4th at 100%. I am not saying if those are good speeds or not, that is just where they have been since my 1st mail-order tune.

 

well my experience with converter lock up is with a stock or small 2800 converter leave it unlocked in all gears, now with a 3000 or higher lock it at 95mph in 3rd gear with 4.10 gear or 10mph after shifting into 3rd gear, with a turbo locking it will help keep load on it and a s/c will bog it down so hope this helps good luck.

 

my tuner did a dyno run with mine unlocked, then another run with it locked. then he did a graph overlay to see where the two runs intersected one another, and locked it at that point.... and i believe it was around 100 mph or so...

 

With around 600RWHP mine doesn't hold under WOT. I get around 2-300RPM of slip. Thinking about trying A tripple disk precision if the money tree ever starts blooming again.

 

Thats what mine is, PI 10.5 triple disk.

 

Well.......I have been trying to get mine to lock as soon as I completed the 2-3 shift, which according to logs is now occuring.

My 2-3 is ~85mph and lock is commanded at 82mph. Scan shows converter mode lock as i enter 3rd.

I am wondering if my trap speed is down as a result altough the et is lower too?
