Hope for us Auto Guys yet...

one thing i wanna try in the coming months is recording the signals the tranny sees in different rpm ranges and throttle possitions to see if we cant create some kind of voltage clamp to prevent it from shifting down when you go WOT.
if we can trick the ecu, we can do up the tranny too =)
 
Glad u got it working joe, I have mine at about 2-3 setting shifts great, I did have the AT light come on when it was turned up past 6. The thing is my scanner couldnt find any codes, (shrug)
 
Great job. Please post a how to if you can. So are the shifts faster or just more firm and direct with addition to the lentech vb?

that's good to know...so how did you reset it? not with the scanner...did you disconnect the battery?

i will...both, feel quicker and firmer

Why would you want to prevent it from downshifting?

yes...please post a how-to...feels like my tranny is starting to slip, so if this can help it gain some pep, that would work...

so it doesnt drop to second gear when you give it boost, reveing the piss out of your engine and possibly taking the tranny with it. maybe not kill off downshifting entirely, but stop it from dropping to second gear when you giver.

Im probably not the only one without tiptronic =)

No you're definitely not and I've been thinking about a way to do the same thing. Unfortunately i have gotten no where. You have an interesting idea here but it's definitely beyond my abilities.

Ive been thinking it would be cool if it would be possible to detect and delay these signals in order to use an actuator to open the BOV, but that to is far beyond me.
 
taken from the turbo auto tuning thread.....

so i did so funnin around yesterday...playing with the new shift imporver and i had it set at 3 no issues, ran fine. i go out this AM to head off to work and i start the car put it into reverse and blinking OD...which of course means limp mode. so i back the setting down to 0, check my scan guage "no codes"???? disconnect the battery, let her sit for a few, hook the battery back up...she starts right up and ran fine for the 40 mile trip to work? weird? i'll have to play with it some more to see what's going on. it could very well be that between the valve body upgrade and the shift improver the ecu just can't handle much more "pressure" increase and throws the CEL. more to follow...

the problem isnt really that your feeding it boost, but the pressure put on the tranny at wot, or just too much throttle makes the tranny shift, be it electronicly or physically with pressure.

Maybe trying to prevent downshifting signals isnt the way to go, maybe just isolate the tranny voltages when you push a button so it wont shift down to second.

then flip that switch again to go back to full auto mode.

would be nice if lentech didnt discontinue that manual shift box. im sure you could rig it up to run both at the push of a button.
 
ya, when i saw that i was like wow, this will be so cool...why did they do away with it anyway?
 
kinda makes you wish you baught one doesnt it lol. Might give them a call, or send an email asking about it, or if they have any input. Do tiptronics keep the gear when you run them in manual mode? whats different about the tranny, or could you just get a tiptronic ecu and run it on a 02 tranny?

The triptronics will hold a gear as long as you want- all the way up to the rev limiter. But the transmission will also downshift for you when slowing down. It will also prevent you from downshifting if that next lower gear would overspeed the engine.
 
is it possible to change the electronics and shift mechanism from an 02-03? looking at my parts catalogue, the ecu's are different pn's but makes no reference to the shift plates or any linkages =( so many threads have said the trannies are the same is why i ask.
 
The transmissions are the same. You'd probably need the 03 ECU and the different shifter.
