Ok I got a Apexi PFC:) Hooked it up and when I first turned the Car on the Check Engine Light come on :D but I fixed that I forgot to turn off the Boost Controller :Looney:

Anyway started it up and all is good, I left it idle (685 to 700RPM)for about 10mins while I was drooling over the Commander Control :drooling: I turned the Air-Con on and left it idling for about 8 to 10mins then I turned on the rear demister and left it to idle and do it's thing.

I then bit the bullet and put it in Drive with my foot on the brake and the hand brake off watching the RPM it was moving a bit but not heaps, going between 500 and about 750. Anyway I took it for a drive :uhh: rolled down the drive way and slowly proceeded up the street (trying to watch the road and the Commander at the same time) it stayed in first until about 3000 to 3500RPM, it changed latter then it normally would and when it kicked into second it was a harsher then normal, third was pretty much the same (it just felt like it was holding out) but it wasn't harsh between gear changes, I tried it to see if it would kick down a gear and that seem to work fine and when I braked and slowed down to go around a corner it seem to be in the right gear.

I tried it a couple of times to see if it would change gears at different RPM rangers but it felt like it was changing gears at about the same point every time (like if you gave it a bit more acceleration it would hold the gear a little longer before changing up) But you know when your driving a Auto and you drive off slowly holding your foot at the same spot on the accelerator and it goes through the gears at relatively low RPM's up to third or fourth depending on the car your driving, this would just hold out that bit longer before kicking into the next gear and it is usually boosting up by then, but if you let your foot of the accelerator it would change up a gear. :confused:

When I got back home and I turned the car off and then turned it back on again I noticed the power button (for the Auto) would flash 16 times, it would come on as soon as you turned the reds on and stay on for a little like normal but after it goes out it would then flash. Anyone know what 16 flashes mean? they where all short flashes. :confused:

So it did work but I do feel that the Auto ECU needs the Throttle Position Sensor and Tacho signal's to work 100%

Anyone got ideas or any thought?

craz0 this is exciting stuff mate!!

Buy the sound of it, it does work!! Not sure about the 'POWER' button flashing tho?!?! I'm guessing it is some self-diag warning signal. You might want to ask 'megala'. He seems to have a fair bit of info on these sort of things.

But also I think you are right that the signals needs to be relay back to the auto ecu.

Can't you just tune the PFC to suit the gears the way it is?? Like instead of all the signals to get the auto ecu to learn about the driving, etc. Tune the PFC fuel/ingition to the way the gear shift.

Is that possible or just a stupid thought?!?! Sorry no mechanic, just throwing ideas around hehe

Keep us posted craz0.

Cheers

Thank's for the support guys:) hopefully I'll get this going 100%

I think the 16 flashes = All flashes the same with no long start flash Battery voltage low, has been recently disconnected or control unit has just been reconnected.

Auto Transmission Diagnostics

1. Have the car at normal temperature in Park with the overdrive on.

2. Start the engine. The power light will go out after 2 seconds.

3. Turn the ignition off.

4. Move the selector to Drive (you may have to use the push button release).

5. Overdrive off.

6. Wait 2 seconds, and turn the ignition on.

7. Wait 2 seconds and move the selector to 2.

8. Overdrive on.

9. Move the selector to 1.

10. Overdrive off.

11. Press the accelerator fully and release.

12. Read the auto transmission diagnostics codes.

All codes are flashed with the Power Light on the auto mode selection button on the R33's.

The sequence starts with one long flash.

If everything is OK, this will be followed by ten short flashes.

Errors are indicated by a long flash in the sequence of short flashes.

1st flash longer: Revolution sensor shorted or disconnected

2nd flash longer: Speed sensor shorted or disconnected

3rd flash longer: Throttle sensor shorted or disconnected

4th flash longer: Shift solenoid A shorted or disconnected

5th flash longer: Shift solenoid B shorted or disconnected

6th flash longer: Overrun clutch solenoid shorted or disconnected

7th flash longer: Lockup solenoid shorted or disconnected

8th flash longer: Fluid temperature sensor is disconnected or the control unit power source is damaged

9th flash longer: Engine revolution sensor shorted or disconnected

10th flash longer: Line pressure solenoid shorted or disconnected

All flashes the same with no long start flash: Battery voltage low, has been recently disconnected or control unit has just been reconnected.

Thanks all :)

Ok I ran the Auto through it's diagnostic mode and third flash was long "Throttle sensor shorted or disconnected"

It still flashes 16 times after I turn the reds on, it's not the battery voltage, going by the PFC when I have the reds on it reads 12.5v and when I turn the car on it goes to 14.4v so all is fine there (it still has the original battery in it:p) So I figure it's flashing because I disconnected the battery, well I hope anyway. :uhh:

Strutto thanks for that but what I'm after is the pin out for the actual Auto ECU, so I can find out where to connect the TPS.

craz0, I spoke to the guy that installed the Wolf3D in the auto R33 GTS-t Skyline. He said it was very simple. He simply used the plug'n'play Wolf for the Skyline, then made sure that the TPS and tacho signal's were still routed to the auto ECU and it all works great.

Hope that helps.

Hey GTS-t VSPEC he didn't happen to say if it was the "Throttle Position Sensor" or the Throttle Position Switch" did he?

Or to what wires in the Auto ECU he hooked these too?

Sorry for the Questions I'm just a little confused, well a lot actualy.

Hi Steve, GTS-Vspec said that you spliced the TPS and Tacho signals into the Auto ECU, what wires on the Auto ECU harness did you splice into I can't seem to find a diagram of the Auto ECU.

Thanks heaps Steve and GTS-Vspec :D

    • From there, it is really just test and assemble. Plug the adapter cables from the unit into the back of the screen, then the other side to the car harness. Don't forget all the other plugs too! Run the cables behind the unit and screw it back into place (4 screws) and you should now have 3 cables to run from the top screen to the android unit. I ran them along the DS of the other AV units in the gap between their backets and the console, and used some corrugated tubing on the sharp edges of the bracket so the wires were safe. Plug the centre console and lower screen in temporarily and turn the car to ACC, the AV should fire up as normal. Hold the back button for 3 sec and Android should appear on the top screen. You need to set the input to Aux for audio (more on that later). I put the unit under the AC duct in the centre console, with the wifi antenna on top of the AC duct near the shifter, the bluetooth antenna on the AC duct under the centre console The GPS unit on top of the DS to AC duct; they all seem to work OK there are are out of the way. Neat cable routing is a pain. For the drive recorder I mounted it near the rear view mirror and run the cable in the headlining, across the a pillar and then down the inside of the a pillar seal to the DS lower dash. From there it goes across and to one USB input for the unit. The second USB input is attached to the ECUtec OBD dongle and the 3rd goes to the USB bulkhead connected I added in the centre console. This is how the centre console looks "tidied" up Note I didn't install the provided speaker, didn't use the 2.5mm IPod in line or the piggyback loom for the Ipod or change any DIP switches; they seem to only be required if you need to use the Ipod input rather than the AUX input. That's it, install done, I'll follow up with a separate post on how the unit works, but in summary it retains all factory functions and inputs (so I still use my phone to the car for calls), reverse still works like factory etc.
    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
