VR V6 T5 in VH where to get memcal

[petespipes]

Hi im new to this forum and its subject matter so im asking for help.

Im finishing anothers project,I have determined engine is VR,im guessing loom is auto but of course need to confirm.

There is no ECU present in the VH body or VR loom in place.
I have 3 ecus lying around and know 2 are VN auto. I have a running VR so have access to a test bed and a VR auto ECU

I have seen tweaked auto ECU for VR set up to carry manual gearbox tune and work with auto loom plus come with a reversing lght loom on ebay.

Im sure you guys have knowledge of these things. Any suggestions? Thanks in advance. Pete.

my suggestion would be to run a vn loom and ecm!

[petespipes]

thankyou for the suggestion Holden202

I thought because VR had a cam position sensor but it seems it only has crank position.

As the car is using manual gearbox does it require a manual ECM? does the entire loom require swap?
I realise the pre VR ECM doesnt have the security style key etc which removes one problem for me.

my suggestion would be to run a vn loom and ecm!

it is possible to use the Auto PCM, just not desirable. ive repinned a pair of VR auto PCM plugs to the manual style before and ran a VN 808 ECU, wasnt too hard, and didnt have to swap the whole loom.

The vn vp or 808 ecm was the same auto and manual v8 and v6 .
Some memcals do auto and manual check http://www.memcals.com he has a list of memcal identification numbers the 4 letters and 4 numbers on the memcal and their functions.

If you post up the service number of the one your unsure about someone here shouldbe able to confirm what type it is.

The cam sensor was only used on VR autos for the banked fuel injection, could also have individual cyl spark trims but holden did not use this. The auto PCM speed sensor input (reluctor style) is different to the manual (hall effect) so needs to be modified if you use the auto PCM, the VR manual or any VN/VP ECM (man and auto were the same) will handle the manual sensor fine. I would also be just finding a VN/VP loom and using one of your VN ECU's, may have to get a different memcal to match the motor but am sure someone on here can burn a different bin to it if you cant.

This option is attractive to me as seems less time consuming than finding and fitting a VN loom.
I beleve im up to the task if its possible to access the info required to pin out the connectors as required?

So im convinced I use an 808ecm,VN. From info provided some memcals are more suitable than others therefore I open these ECM boxes,record the numbers and visit the site suggested to gain info on what I have on hand?
[dec_head said-some memcals do auto/manual check]
dec_head the link you provided [thankyou] took me to robs creative callibrations but I couldnt access the list you suggested.I will open these boxes and post what I find.

Many thanks to you guys for sharing your time and knowledge.much appreciated!
I have previously got one engine goning as stand alone,Toyota 2jzgte,my favourite engine.
A friend supplied copy of ECU pinout with simple instructions ie 12v+,Earth etc relating to pins.
Even I could cope with that.Having basic mechanical knowledge and a love of modifying its this area that I need to skill up in.

you might be right with reading the wiring diagrams but i reckon you'll be getting frustrated removing all the pins from the ecm plugs, they can be a real biatch when you first start doing them

[Jayme]

basically what I did was take take the pin listing for VR auto and Manual and matched them up. pulled each pin from the VR auto ECM plugs and put into its correct corresponding place in the manual plugs. then tie up all the unused auto wires into a ball and throw under the carpet. the 808 is the same ecu as a vr manual, just without the data lines, so take a VR manual tune, turn off VATS, burn it to a memcal and run in the 808.

let me know if you want help matching the 2 lists of pins for the swap.

I still think its easier to repin than swap the whole loom, its not that hard once you get the knack

I will try it.Its a skill I feel i need to learn.Accepting that it will not be easy first time.[repinning the plugs]
So I think I now have a path to take.
I still need to confirm I do have a VR auto loom.The loom has a tag 300mm short of the ECM plugs.GM 92039 347
I ran these numbers but found nothing.I will now record the wire colours against pin numbers and see if that confirms the loom identity.
Regarding getting the VR manual tune less VATS onto a memcal,what is the most practical and cost effective way to proceed?
I am based at 4207 beenleigh QLD and I do not have personal contacts playing with these memcals.
Can you guys refer me to someone known here?
