line pressure can be increased to 100% by disconnecting the resistor to the duty solenoid A. But without reprogramming the ECU/TCU this is about as far as you can get along the lines of an add-on. A modified valve body will sharpen up those shifts better than anything else and tapping into the TCU to reduce shift time would help as well. Besides that I see no room for any real improvement. But this is the problem with "secret" projects as no one knows. It is good marketing to leave people in the dark of what they are signing up for as it boasts interest and curiosity but for those who actually care what they are putting on their car... It needs to make sense first.

Please don't take me as a naysayer, but I tend to agree with YT.
I want this to work, badly, but I don't understand how, what is basically a piggyback, can do much more than what Smallcar's kit does. Without getting to the heart of the tranny's controls, IE the TCU, dramatic changes are difficult. That said, I'm reserving judgement, until I see the prototype & hear a basic breakdown of it's function. Add to that, if you get a nice reflash for the TCU I still can't use it, as my '96 is OBDII

Um
Anyone thought of a Level 10 shift kit? How would this new kit shift any faster than that? Only the valve body need to be modified. No changes are necessary in the ECU. I thought I proved that.

What do you expect to see on a dyno? How a transmission shifts has nothing to do with HP/torque numbers.

You lose third gear. And it felt way too...juttery to me.
(By 'lose third gear' I mean that when you put the shifter in '3', the transmission won't do diddly) |

That's what I mean. Coast down a hill, drop shifter to '3', laugh as the tach drops to 1k then bumps back up then drops...etc.

Have you ever seen a before and after dyno plot of a car going through 1-2 and 2-3 with a shift kit installed? The 'snap' you feel is hp/torque that was not there before. It is 'plottable' on a dyno. The delay you feel stock will show as a hp/torque dip on the dyno graph. The snap will show as a hp/torque spike (gain). If you were to plot the points a the beginning of a shift and after a shift has been completed vs time, the gains in between these seconds can add up on a road course.

Kinda like the difference between granny shifting and slap shifting a manual trans. You don't gain any actual hp/tq from the engine, you just apply available hp/tq more affectively. Who gets down the 1/4 faster, the granny shifter or the slap shifter?
Be interesting to see what this ubersecret contraption is....more interesting to see how much it will cost. Doesn't the level 1 chip do the same thing but actually affect engine performance and increase available hp/tq at the bottom end? |
