In this case, I believe "Program" = "Algorithm".....Great Product!

Stevo,

Are any of the computers able to run both the engine management and the tranny??? Or will I need seperate computers for my LS1 & 4L80E???

Thanks,

Ryan

BigStuff3 and Powertrain Control Solutions will soon offer combined engine/trans controllers with manumatic capability.

I wuz a-tryin to avoid them fancy, uppity words like Algorithm.

I agree Steve, why use a big word when a diminutive one will do? ;)

Steve have you used the paddle shifter at the track? We took my friends m3 and it was a blast using the paddles, but we had to use the shifter when turning and having to shift.

Not yet but it is a blast to drive around town with..Also, people are fascinated by it. :thumbsup:

Sorry Steve, I was only making that connection to try and link the two, because I know people are interested in changing parameters, and understanding how the algorithms work is the first step in calibrating shifts correctly. I can't wait to read the writeup in June...Congrats! :thumbsup:

I understand. We are making the same point: It's all about the computer program or algorithm.

Folks ask well why? Why can't I hook it up to my TH350 somehow with a CO2 bottle like Steve Strope did or with a linear actuator motor? It's still just a hydromechanical transmission. All you accomplish under those circumstances is to replace the motion of your arm, the floor shifter and the shifter cable. You are still operating a "dumb" transmission. If you feed a carburetor with an electric fuel pump, can you call it fuel injection? No. You need a computer, sensors and a map (program or algorithm)


T/A,
I've run it at the track and used it at autocross. No road course yet.
In the 1/4 manual mode is better when wheelspin is present. Otherwise the computer sees mph increase and prematurely upshifts. In a perfect world, automatic mode would be better. But when traction is limited or you need to overcome a fuel stumble or some other variable, I'll take a paddle shifted manu-matic over any other option.
When autocrossing, driver's typically just leave their transmissions in 2nd gear. The course is slow and tight enough that shifting is cumbersome and unnecessary. But with paddles located on the steering wheel and ultra quick manumatic shifts, it is possible to paddle shift between 2nd and 3rd gear. Downshifting back into 2nd induces engine braking which can be beneficial on certain corners. I have a separate auto-cross program that I can load. Has a little extra line pressure built in and lower downshift prevention parameters.

very cool
 

steve

your product sounds awesome ...
i may just have to get that...sounds like it makes an automatic alot more fun to drive..and i would like to autcross mine some ..just to drive the sh@# out of it..thats what they are for right?

Steve,

You've probably covered this already, but I'm too lazy to go back and re-read.... Does the driver have the ability to choose between letting the tranny do the shifting and doing it myself with the Shrifter??

Thanks,

Ryan
