It stands out in the logs but I was attributing the AFR blips and MAP dips to shifts not necessarily shift retarding the timing . I’m not making some crazy horsepower blowing up powerglides so wonder if it is a carry over from the OEM strategy or an adaptation from drag racing.You know I'm not sure I have ever even opened up this table. But if it is pulling timing on my truck then I am going to turn that off.

Well it is a form of torque modulation which is in most all OEM programming. I like to turn that off. It is there to help the transmission live but mine is built so I will make sure to turn that nonsense off lolIt stands out in the logs but I was attributing the AFR blips and MAP dips to shifts not necessarily shift retarding the timing .

I keep it locked on the 2-3 but I got the best trans I could by from A1. I don't lock the trans in 1st yet as I don't feel the truck makes enough power to utilize it yet. Once I get built motor and fab up the twin turbo kit I may think about it.Are you guys unlocking the converter on shifts? That’s a parts saver too for more mild/stock transmission builds.
I decided not to use lockup after 75% TPS and just have it in O/D now. I just installed a new engine so now I have to baby the transmission. I will re-enable retard before I get to WOT tuning.Resurrecting this thread a bit... Was just combing through these older threads to see if I could learn anything and after comparing my shift retard settings mine are currently set at 2.0 degrees @ 82% load and 6 degrees @ 100% load. Everything else below that is 0 degrees retard. I'm almost certain I've never fooled with those setting so it's interesting to see mine so different from yours. Looking at my last logs it does drop 6 degrees during shifts, but those drops last a total of .33 seconds so pretty consistent.
I talked with Chris at A1 earlier this week about a transmission build this Winter... until then I don't think I'll take the chance of taking the retard out or using lockup though.
I would really like to see your PxS transmission setup one day on both trucks!AS I mentioned earlier, I stay locked on both trucks after 35 mph (the red truck has a top notch transmission and converter, the white truck, just a valve body and a single-clutch). I use retard on the shifts to try to soften them a little more than to protect the driveline.
