VY V6 Wagon auto to manual conversion

[sv9096]

Gday guys. me and a mate are about to start on converting a VY V6 wagon from auto to manual.

What we have is a complete kit from a VU ute. We got all mechanical parts and the VU wiring loom and ecu.

Is this ecu and loom compatible? What i want to know is whats the best way to get the wiring done.
I have looked around for factory loom and ecu bu just cant find any, or any information on the net.

Also does the BCM need to be re matched if i was to fit another ecu?

All help appreciated.

Brilliant, I'd use the VU parts, engine and all for the conversion.

Is this ecu and loom compatible?

Yes

Also does the BCM need to be re matched if i was to fit another ecu?

Yes

If you are not worried about a numbers matching car (i.e. original engine) I'd just swap the VU parts, engine and all, straight to the VY. That way your PCM-BCM, engine, gbox, wiring loom etc. all match. The only VY things I'd leave behind would be the A/C and cooling systems. Actually check the cooling system, it may be heavier duty in the VU because its a ute.

Thanks for the reply mate. Ive since sold the engine from the ute.

So i can fit the VU loom and ecu and then have the ecu matched to the bcm and thats the electrics taken care of?

Do you know of anyone that can do that if i was to post them? Just to save towing the car to a holden workshop?

Thanks again.

Ask Alan (Hooter) about matching the PCM-BCM.

As long as the loom matched the engine everything else should be fine. From memory they don't get to bad to do until the VZ VE with the AlloyTec. Those things from what I have heard can be a nightmare with wiring depending on dash configurations etc. The VY and VU is still relatively easy if you are capable and know your way around a wiring loom (make sure you have a wiring diagram.

Actually, Alan may be able to show you how to modify the VY loom to fit the VU gbox. Maybe you should drop him an email.

Thanks mate, Ive been looking around for wiring diagrams but havnt found any usefull ones. Do you know of any i could download?

I will send Allan an email also.

Thanks again

No sorry, I get my stuff from Alan or Derek. To much of this stuff on the internet isn't accurate so once I find a reliable source I stick to it.

Unfortunately I dont have anything after VT (The later stuff is all electronic I beleive), Alan should be able to help though.

I think you're gonna have problems
The VX and VY run different programs (operating systems)
The main difference is the dash, as it has LCD display and you may notice the little padlock light.
There must be differences to the BCM as well.
On the super 6 versions, they have the same pcm as VT, and we can tune a VX super 6 with VT super 6 program, but you cant tune a VY super 6 with either VT or VX super 6 software. ( the padlock flashes)
i think it best to get a VY manual pcm ( I may have one)( not sure,it might be VX also) and then get holden to relink to bcm or
I can do you a kalmaker VY tune for it.. Its the same as factory, but I can turn off the VATS, and it will run straight off.

Thanks for chiming in Alan. I thought the VZs were when it got hard to do, learn something new everyday Sorry about that sv9096, this is why Alan is the guru.

[sv9096]

Thanks guys, So with Allans post, I can have the VY auto pcm re flashed with a manual tune?? How much you want for that Allan?
What about the VU manual loom, would that be compatible with the VY?

[DerekBell]

We don't have issues with other software etc etc, but we do have issues with software that supposedly offers another "cheap" Delco editing service (Specially as this is a Kalmaker Delco editing website). The guys have spent a lot of time, and money, to get Kalmaker to where it is, and I think it is a but rude to advertise "cheap" services for the same thing. Try and get on a Ford site and advertise your commodore...
If you want to let someone know of the other options, simply put it into a PM and let the member know directly.

I am pulling the trans and wiring from the vy this weekend. Once ive got the vy auto loom out i will compare it and maybe even pull both them down to see if the vu manual loom is compatible. I havnt been able to find any wiring diagrams for either on the net.

I will post back with what i find

[sv9096]

Pulled the wagon down on friday night. Fitted the new box etc on saturday morning. Looked at the wiring and as i was thinking the VU loom wouldnt fit straight up. What im going to do after some looking at wiring diagrams is keep the VY auto loom and change the speedo plug over from the manual loom, fit the reverse light plug from the manual loom and bridge out the inhibitor wires.
Will be getting the auto pcm re flashed with the manual tune.

[Hooter]

This is probably the best idea with the harness. I believe they are nearly identical.
With VY, at some stage, they changed the 3 plugs that connect near the brake booster on VX/VU, and put them inside.
If your VY harness has the same 3 plugs as VU, and in same place, with all colour wires matching in all 3 plugs, then its 'probably" a safe bet that you can use the VU harness.
If not, then remove the auto trans wires, retaining pink/blue stripe wire. This ignition to trans power. Use this as power source to reverse lockout if using one, and retain speed sensor plug.
i can flash manual vy tune if you need one.

Thanks Hooter, Only during the week i finished off this job, After comparing some diagrams I ended up changing the speed sender plug over from the vu loom, Fitting the reverse lights plug from the vu loom and brodging out the inhibitor wires. Leaving the round auto plug and another square plug unused. Had the pcm re flashed. Plugeed it all in turned the key and awy it went good as new.

It was all a very easy job. All the mechanicals bolted up too easy and didnt even need to remove the wiring loom.
