Any one have a viper turbo with an anti lag program yet

[Studroes144]

Yes I have the pti, when the button is pushed timing stays at zero and we could not get it to build boost, on 2 different sleds with 2 different power commanders and ignition modules. It took a bit to figure out how to get the launch master to work on the viper, but now it works awesome

That's good to know, when the button is released is the power right there? No bobble or anything like that? That's the main reason I'm ditching the gems controller is because I can't tune it enough to do everything I want. I can adjust fuel so that on a launch there's no hesitation at all and it's very crisp but then on longer runs it'll run lean and vice versa, adjust it so it has plenty of fuel on longer runs and it way to rich from launch to mid range speeds. With the gems when I go from a dig my afr gauge bottoms out at 10 and that's where it sits til probably 70 mph then it starts to lean back out, that's my main reason for switching to the pc5 setup, stutter was just an added bonus with the ignition module. A little off topic but what are you pulling for timing at different boost levels?

This is 2nd run down the track at 10 lbs running very rich, clutched very heavy. Power commander works very well with hurricane's injectors and tune in it - it's tuned rich but Dave does this to keep them safe on the trail. Next run I added boost and pulled some fuel(still very rich) and ran a 9.5 @ 138 with a BAD 60ft.

Ya u can hear it's pretty heavy in the clutchin, still darn good speed! So are u running stock engine and pulling timing or lower compression setup? Or is that hush hush? Lol

Shimmed motor with rods and valve timing. Runing 14 lbs and stock timing with c12.

Is that an MCX turbo? I have the MPI Stage I but 13 #'s is all it will blow. Was going to build my 2nd XTX with a CAT XF 1100 turbo capable of about 17 to 18 lbs. Still working on it with Allen Ulmer hopefully by late fall!

Its a Hurricane turbo kit

Wow did not know they would blow 14#'s do you know what the max #'s are

2 Vipers
Both with MPI turbos. Zero lag. Lots of smiles.

Why delay the fun?

Do you know what wires you used to hook up the launch master on your viper.any info would be greatly appreciated.thanks
