That map makes sense; obviously, even a 20W oil like ATF flows slower when it's cold so the map is aimed at how long the TCC takes to apply with fluid of different temperatures.

A second map would be better. I was looking at some more of the "functions" this afternoon and may have come up with how to make the TCC apply more quickly (firmer) with varying APP.

Expect updates.........

After thinking about it there must be a map to control TCC vs APP. My current Drag tune will only lock the converter (earlier) at WOT. Otherwise will stay unlocked untill after 3rd gear. Hope you find a way to do this, it would be really cool to have even more control over these things.

Well that's easy since there are many functions relating TCC apply to APP vs. vehicle speed in each gear. I have MANY variations in these functions because each program type is going to require a different TCC apply speed in different gears. I was speaking more along the lines of TCC apply rate depending on APP. For example, having a less harsh apply while simply accelerating with traffic at less than 1/3 APP but then when you're shoveling the coal to it, have the TCC apply more firmly.

Gotcha, would make alot of sense to have that second map to change the TCC application rate. Pretty irritating when the TC "bangs" in when at a light cruisie. Not to get off subject completely but what do the OBS guys do to controll their TCC, thought it was more like an on/off switch, no PWM.

[cleatus12r]

It is an on/off type deal and increasing the feel involves increasing the line pressure. This then requires a reduction of pressure during shifts......

[907DAVE]

Ahhh......I see, up the line pressure to firm/quicken application, and drop them to shift on time and keep them smooth.

Wish I had a chance to look at the program and some of the maps so I could get a better idea of how this all works!

Want some screenshots?

Or will that just make it harder to wait?

LOL.....yup will make it harder for sure, but if you dont mind posting a few I wouldnt mind looking at them.
