hi can someone tell me if the tiptronic shifter will fit in a tf and work? if not what are the differences between both shifter! thanks

Huh, so you have a non tip tronicshifter and you want a tiptronic shifter?

No that will not work, the tiptronic gives you the option to manually change gears where as on the standard ones its well manual for the first 3 and then its auto.....

To make it work, you need a tf sport ecu, wiring loom, shifter and possibly keys and immoboliser/locks and retrofit that in

thanks for replies! i just like the look of the shifters better than standard!

Similar question.
I have a KH Verada with the 4 speed auto.
When running on LPG it holds the gears too long because of the extra throttle needed running on gas.

Is there a way to either use the tiptronic shifter, or fool the trans into shifting faster?

When cold and running on gas, it won't shift at anything less than 3k rpm. Even warm it still hangs on till 2.5 with a feathered throttle. I end up driving with a 'point and squirt' style rather than simply holding a small amount of throttle.
Around the back streets it is killing my fuel consumption!

I need to do a heater core at some point, so if I need to swap out wiring looms, that would be a good time to do it I guess.

Tippy has it's minimum shift points so that is not the answer.
The 4 speed is set up to wind out quite a bit through the gears to move the car quickly.
If you really want to set your own shift rpm, you need a manual conversion.

Just a guess, maybe your TPS is faulty or out of adjustment?? my KH is slow to change gears too

If you lift off the throttle most (but not all) of the way it should change to a higher gear. Otherwise as stated above you have faulty or out of adjustment throttle position sensor.

Will check the TPS once I get back from the South East.
Thanks for the answers.

The auto mode shift points rely on the TPS value, unless the car is fitted with TCL in which case it will have an accelerator position sensor (APS) and that will control the shift points.

If you have tiptronic shift you can of course shift when you wish, though certain minimum/maximum speeds apply to each gear.

It seems to me that your LPG system might not be adjusted as well as it could be if the throttle response on gas is quite different from petrol. Any attempt to work around this with ECU fiddles would also have to be switched in conjunction with the fuel switch, otherwise the shift response on petrol may become awkward instead.

I have TCL.
Will get the gas retuned, however I doubt it will make much difference since it was retuned not long ago.

Could I add a resistor to the APS that is wired in via the gas/petrol switch to alter the shift points?
That is to say, would adding a resistor lower the shift points? Wiring one in with a relay that only activates while on gas is easy enough.

A resistor won't change the shift points directly - if inserted so that it decreases the voltage detected by the ECU, it will cause the ECU to think the throttle is open less and therefore use a lower speed as the shift point. However you need to be careful not to overdo it, as the ECU needs at least 80% of the maximum input voltage (i.e. about 4V) to do WOT shifts.

At least in a TCL equipped car, the engine code is still getting the throttle info from the TPS so engine management shouldn't be affected. However you need to be careful not to interfere with the idle switch operation which comes from the APS in a TCL equipped car. If you stuff the idle switch operation up, I expect that your idle quality will deteriorate...

In a non-TCL car, adding such a resistor would be likely to cause problems in the engine management.

I still think there might be a problem with your gas system though if you have to have the throttle around one third open (that's the approximate value for the shift speeds you've mentioned) to get any usable acceleration.

Food for thought.
Given how the gas is tuned I may have the idle too lean and the wot a bit rich.
I'll get hold of a wideband and double check the tune. I only used the narrowband to do the last tune.

I could use a voltage scaler to fiddle the shift points and still get the correct max and min voltages. Even on petrol it holds the shifts a bit long for my liking.
I have the PDF of the workshop manual, so I'll have a look and see if the APS is set correctly before I fiddle around with anything else.

I thought of mentioning something like the Jaycar (Silicon Chip magazine) voltage adjuster kit, but at $80 its a bit expensive. That approach would be better than just a resister though.

This is not an uncommon complaint it would seem. In your case, I would suggest that perhaps there's a little bit of conditioning to the feel of the accelerator with the LPG which may be skewing your perception a bit but others have also complained. I recently helped someone adjust their shift maps (in a J series ECU) to get closer to their preferred driving style which favoured earlier upshifts.

My last auto car was a Falcon, known for rushing through its shifts as fast as it can.

Driving it today I made an effort to lift off when I wanted a shift and it works, a happy compromise I feel at this stage.

I have retrofitted tiptronic.

The kf and Kh ecu has a lot less memory and computing power than the Kj and onwards ecu's.

It's actually quite easy and made my gearbox drop to converter lockup quite a lot quicker and made the shifts more crisp more often.

Had a look through your build thread and couldn't find details as to how you got the tiptronic working.
Could you please provide me the information you used to get everything working please?
