anyone using boost by gear ? - SRT Forums

apexcrazy · 09-16-2009, 11:08 PM

Has anybody had success modifying the torque vs gear table ?
Its mentioned some it one of the stickies above . That was back when sourkraut , Nick & others were figuring this thing out , , but I havent heard anything about it since .
Any current users here confirm it works , and if yes , please feel free to share your experience with it , and what settings your using .

Isn't by gear an auto trans app and T vs MPH is the only one that works on a Srt?

Quoted from Nick Chestnut's post in the SCT Wiki sticky , pages 3,4,&5 contain a discussion about this feature .

-->"Okay, so I officially confirmed the functionality of torque reduction based on gear this weekend. It functions exactly as I described in my earlier post...

Cell 10 = First Gear
Cell 8 = Second Gear
Cell 7 = Third Gear
Cell 6 = Fourth Gear
Cell 5 = Fifth Gear

Mana, can you confirm these results? I tested this extensively this weekend and ended up with the same results every time. I know you had mentioned you were thinking differently; I'm curious what you're finding."<-- ( End of quote . )

The torque limit tables are in Newton meters , not foot pounds , so Im not sure of the conversion factor , but If nobody here has any experience with it , I will try fiddling with it . Can anybody confirm funtionality/non-funtionality ?

1 newton meter = 0.738 ft-lb

I had it working...

It works for me. My WGA spring is just a little bit to strong for 1st gear though.

Awesome ! So the gear positions are backwards , like Nicks post says ?
Ill give it a shot this weekend .

Thanks guys .

Ya, it's just like it was posted above. I thought it was different way back when it was posted, but I wasn't looking at the program when I stated that. Once I looked at it I knew it was right.

anyone know what variables the PCM is using to calculate gear?

I always thought it was speed and RPM, but it could just be doing it by speed. The problem I have is generally after about 5500 ish the boost shoots up more then where it originally was set causing me to spin the tires.

Yeah, that why I'm curious to figure out how it calculates gear. RPM v MPH would make sense, if there was an actual table, but once you start changing other variables like redline and gear sets, this could really screw up the math.

Mana: why don't you just adjust the desired torque map at the 5500+ range

Because I want to hold my boost all the way to 6000... My torque curve is completely flat as is my desired torque table.
