to Wamuranman:
The Tech II was purchased through the dealer network and is a GM tool which is also used here for all Holdens. It is just loaded with different software and one can do an update for the latest models. I bought it through an US dealer and the Tech II plus Candy module (for the newer network in the truck - at the time) and the whole workshop manual with all service and repair diagnostics was A$ 4500.-
The LMM and the LML all have more complicated emission control.
Mine was one of the last LBZ built and I ordered it deliberatly because I did not want the LMM.
Mine was built on 26th of August 2006 and a couple of days later the Flin factory was retooled for the LMM.
I have the BD manifold, which gets rid of the kink in the breather
have other mods for better engine breathing including a 6" stainless steel exhaust front to back with additional muffler .. I like my trucks quiet. I have the leveling kit installed which brings up the front and has the dual shock assembly (Bilstein) with pitman idler enforcement. Pyro gauge before turbo, additional fuel filter with lift pump after the 260l long range tank. A Sterling bull bar, a DC DC charger and 440AH Batteries on the bed, double Alternators, rear Airbags, a decent onboard air system with a 100amp compressor, and many more things including my large HF antenna, HF and UHF/VHF radios (I have a ham licence - VK6GMD).
Recommend a Tech II ?
Well, I had 3 problems from conversion where the guys made a boo boo: 1 was a stretched wire in the HVAC harness which led to hot air from the driver side, another one was a leaking aircon hose after 2 years - it was crimped wrong and third a missing hose clip on the right front which lead to rubbing the ABS sensor line on the back of the wheel. All this would probably have been covered by the warranty with the conversion, but I did it myself abd it was quicker and much less hasel than leaving it with a repairer who did not even have a Tech II. I can service the truck in all aspects, injector flow, transmission relearn, real time monitoring the engine and extremities if something is wrong -- I occasionally had a
check engine light coming on when towing the boat and putting the foot down uphill when I was passing Caravans and Trucks puffing up the slope. I have a sensitive turbo and will get a replacement now from the US - just in case, but I know it was nothing serious so far, I am running a tune - programmed with the Diablo Sport Predator, but I do not use the max setting, since I do not have my Suncoast Transmission kit installed. It is on order with a few other things from the US right now, including tyres and an ABS trailer brake system which is directly integrated in the vehicles OBDII bus. So not a break controller which guesses what you do by sensing enertia but one which gets the info from the vehicles brake system, and the good thing still much cheaper than a local brake actuator which does not even have ABS.
I loos a couple of litres per 100 due to the additional weight and the wider tyres and the roof rack as
well as light beam accross the top - not on the picture - oh I forgot - have a hydraulic winch in the box at the front on the bull bar.
Coming back to the Tech II and recommendation: I do not know if you want to spend serious money on the diagnostic computer but for me it is a nono to buy a vehicle and go bush, get a
check engine light in the middle of nowhere and have no idea what is wrong, and that also would apply to any other vehicle. It would make me nervous. Also knowing that you pay good money for the dealer just to read a code is like putting speed cameras in a 80 zone which is a 500m long. This is entrapment, maybe it is just me but my peace of mind is worth $4500 or even more and I guess it will pay off when I do need serious servicing. There are cheaper solutions now - not at the time
Scan tool
also
scan tool 2
You will get away with much less money nowadays. At the time the GM module did not support the new bus (Can-Bus) and it took a couple of years for the guys to catch up. So I decided to have the original dealer equipment, today I would buy Autoingenuity no doubt.
Any more questions ?
here a couple of pics with my radio stuff
above is the Hi-Q 6" coil HF 160m - 10m antenna
above you see the radios with the 10" pc screen which is a full Windows 7 system (used to be XP) running 2 different navigation programs, my mp3's directly into the head unit of the truck with additional cabeling. Have internet and all the 8 cameras can show on the screen as
well. Have an alarm system with voice output and proximity sensors.At the moment I rewire the cockpit with a custom roof console and computer controlled output and sensors via a TCP/IP bus. I am building a Caravan and will have the airbag pressures and cameras and other switches for the caravan wired to the TCP/IP module in the truck and can
check and set everything through the touch screen. Why I am doing this ? Just for fun, because I can. I love gadgets as you can tell . lol
have fun
