Hi all, I'm just trying to put an MSQ together for my 4L80 - the one on the build page is for an extremely old version of the code - is it going to be updated at any point so there aren't so many errors when loading it?
Could someone please take a look over the attached MSQ and see if it's OK? I don't want to kill my freshly built transmission the first time I take the car up the road....
It's behind a 580hp LQ9 - should I be looking at modifying the pressure control table? Also whats the best TCC control?
Thanks... SJ

Re: 4L80E MSQ
Hi,
here is my msq.
maybe not the latest code, but not so old.
You should be able to use it or get the right parameters.
I use these parameters on 2 cars: one 600HP 5.3 turbo Chevelle and a 800HP 5.3 turbo Camaro.
Early 4L80e.
For TCC, I use ON/OFF, no PWM.
Have some fun with the LQ9 and the 4L80e

Re: 4L80E MSQ
Great thank you 
I'll probably set my TCC up as ON/OFF for a start - just thought it might be a bit harsh, but I'll give it a go. That said, my transmission isn't stock and it's likely to shift hard anyway, so if it is a bit harsh it shouldn't matter.
Hoping the LQ will be around 580hp...
Still a work in progress...

Re: 4L80E MSQ
Nice engine. what car is it? a second gen Camaro?
For me the TCC is OK in ON/OFF, anyway, much smoother then 1-2 shifts (transmission upgraded with Jakes shift kit)

Re: 4L80E MSQ
Thanks, yes it's a 2nd gen Camaro. The upgrade's been a long time coming - been off the road for about 18 months now - but the end is in sight.
I'd love to add a turbo or supercharger to mine - maybe one day
Your's looks like its fun!

Re: 4L80E MSQ
If you look at the msq, you will see 2 tables:
I use Table 2 for "normal" driving.
And table 1 for "sport" mode which allows more revs before upshifting. The table switch input is connected to the input 2 of the lever, inside the GPIO. then with the shifter on OD position it selects the table 2 and in any other position, I get table 1. This allows no kickdown to avoid torque surprise while cruising, in a curve or slippery road.
I hope you will be able to drive soon your car. 18 month is long without driving
