Diy - tippy conversion



I found this file I wrote for another member some time ago, so I thought the club can benefit. Basically, the following allows a 4 speed auto to be converted to tiptronic, without changing the gearbox, just the electrics.

TIPTRONIC CONVERSION – KH


Step 1 – Parts;

You will require – KJ BEM, KJ ECU, Shifter mechanism preferably chrome, the plug with wiring on it for the shifter, a spare plug with for the ECU, and a KJ or TJ TCL ECU.
You will also need a key, but while I have supplied all the locks and etc, I would not put them in your car as this means the key under the dash wont unlock anything at all. Boot or glove box, and this means lots and lots less work.

Step 2 – Wiring;

There are only a couple of differences with the wiring of the Tippy system in comparison to normal Auto operation.

The first is plug B111. B111 is the majority of all the editing we will go through. It has 3 rows and is at the top where the clip is it will have 2 groups of 2 pins (wires or spaces) on one side of the clip, and 1 group of 3 pins on the other side. I will provide a colour for this plug later.

A)

First step with the wiring will be the plug from the shifter mechanism.

6 wires go to it.

In your existing plug B111 at the ECU there will be 3 pins.
Pin 110 – Yellow/Black trace wire – goes to L at the moment
Pin 122 – Brown/white trace wire – goes to 2 at the moment
Pin 109 – Brown/Black trace wire – goes to 3 at the moment.

You will need to cut these wires with enough length so you can use the pins in the plug again.

Pin 110 (ECU plug side)- Is reused and connects to yellow/black trace wire in the tippy shifter plug.

Pin 122 (ECU Plug Side) – Is reused and connects to Brown/White trace wire in tippy shifter plug

Pin 109 (ECU Plug Side) - Is reused and connects to the Brown/Black trace wire in tippy shifter plug.

3 wires down!!!!!!

The next wire to deal with is the Blue/Black trace in the tippy shifter plug. It will connect to the ignition wire power source anywhere in the car. The Audio harness or Climate control is a good place to get it. The ignition wire is always Black/white trace. Don’t get it from the ECU.

After that, the next wire will be Yellow/blue trace (Pin 1 on its own on the top row next to the clip)in the tippy shifter plug. This wire splices into the Yellow (solid colour – no trace) wire in the B111 plug Pin 102.

Last wire in the tippy shifter plug.

This wire is yellow/blue again, but it is in pin 5 under the clip. This wire goes to the pin 128 on plug B111 but NOT on the ECU plug side. The pin 128, which is a white/red wire in they existing ECU plug, is cut and you connect the yellow/blue wire to the car side. Leave the plug side of the wire as a dead end.

TIPPY SHIFTER WIRING DONE!!!!

75% complete.

Step 2 for the wiring is to make the instrument cluster lights work to tell you which gear the tippy system is in.

3 wires are needed for this. You will be reusing the ones at plug B111 that you cut earlier. However this time you will be using the ‘Car’ side of the wire rather than the plug side of the wire.

L Light – Yellow/black trace car side wire that was cut earlier will now need a new pin attached to the end of it – Cut this pin from the plug provided. Make sure it has enough length. Plug the pin into the existing B111 plug, in position 105. 105 is on the top row, and next to the clip.

2 Light – Brown/white trace car side wire that was cut earlier will now need a new pin attached to the end of it – Cut this pin from the plug provided. Plug the pin into the existing B111 Plug, in position 118. This is directly below position 105 in the middle row.

3 – Light – Brown/black trace car side wire that was cut earlier will now need a new pin attached to the end of it – Cut this pin from the plug provided. Plug the pin into the existing B111 Plug, in position 117. This is next to 118 in the middle row of the plug.

FINISHED!

That is it. No more issues. 9 wires total to edit, and 3 new pins required.

The end result, will be the shifter works as factory, the lights for 32L in the cluster become tippy gear indicator lights.

The only thing that isn’t like a KJ tippy, is the 4 light. As your cluster does not have a light for 4th gear, I have done the wiring design so that when the car is in D (not tippy mode) the D lights up, but when the car is in tippy mode and 4th gear, no lights work. So that way you can tell if it is in sport mode still but looking at the cluster and simply shifting the lever over to D again makes D light up.

The TCL upgraded software module is plug and play.

You will notice that the ECU behaves a little differently than the old one. It is 256mb as opposed to 128. So it is much more sophisticated and clever. Things like it will instantly apply the torque converter lock up when coasting.

You will also get the 16 beeps with security light flashing when turning the car on. This is because 1 wire that goes to the SRS system from the new BEM is not present. You cannot add this wire without replacing the ENTIRE srs system and having a new SRS ECU and changing the plug for the SRS system. I would never do that. If you have auto headlights, simply open the BEM and remove the piezo speaker inside. The beep stops and you are left with the security light. However this beep is also your headlight warning buzzer which is why I mentioned having auto headlights first.

Job Done.

With regards to the ECU, if access to a reflashing rig is available I believe the stock J series 4 speed ECU can be switched to tiptronic mode easily. I just need a volunteer to test...

Is this conversion possible on a tj 2002 exec?

Using a TJ2 TJ exec ecu and bem.
