The complete Vn-Vr Manual Conversion Guide.

[delcowizzid]

a vr manual ecu is the same as a vn ecu just doesnt have high speed aldl apart from that it will run a vr fine with the right tune

 

[azzfox]

what about VR having sequential injection, different speed sensor pulse, cam angle sensor, extra o2 sensor, MAF sensor.etc? Im not arguing, just curious. or is that what you meant by "with the right tune"? ie. not simply plug and play? I just figured the VR ecu connectors would have alot more wires and possibly in different locations.

Just been trawling over the internet and came across these:

Holden Commodore VR v6 auto ECU converted to T5 ,,, - eBay, Other Car Parts, Accessories, Car Parts, Accessories, Cars, Bikes, Boats. (end time 13-Sep-09 15:31:26 AEST)

Are these computers the real deal or much rather do they work just like a genuine manual computer ie engine runs and idles fine, all lights and dash waring lights operate as normal?

Just wondering if anyone has had any experrience with them

I have seen people selling "manual starters" for much higher prices than auto ones, and recall posts on this sight of guys having dramas with them and i guess i'm about to find out.

as per the last photo the distance from the crank snout to the ring gear appears to be the same. Same tooth count and the starter bolts to the block too. Leaves two possibilities, snagging on the bellhousing? will bolt it to a bare block asap - or does it hit the step on the outside edge of the flywheel (third photo) ??

That brings me to the clutch. The smaller disc and cover are good old HOLDEN 6 for three on the tree all synchro box/ M20 6cyl. SAME SPLINE
If i redrill the flywheel for the smaller cover i can turn off the step and lose some weight where it is the heaviest when rotating-same benenifit with the smaller cover moving the rotating mass closer to the centre

Trade off - the finger height on the smaller cover is about 7mm lower - will make left foot braking easier by dropping the pedal a bit but wont have the same travel, HMM also lose some clamping force, HMM
Thoughts ???

Got the box in easy bolts straight up with the auto crossmember even and its not a heavy box to bench press in by yourself compared to many :thumbsup:

As for the bloody starter :bang::bang::bang: it all came out again, the snout on a manual starter must be puny as - i dont have one and they go for premium prices when you can find one, i DO have an auto starter and they plentifull and reasonably cheap - soo i figured i'd make it fit. I ground off the 'ribs' off the starter snout and marked out the bellhousing bolted to a dummy block and got busy with the die grinder as a poor substitute for a milling machine. Its a bit rough but it did the job, if it was a daily driver i'd shape up some alloy pipe and get it welded in to close ot all off again, where i have gone through i have taken out a bit further and smoothed off to reduce the chance of cracking.

There is no snout on the manual starter. But thats a bloody decent effort right there!

so just to double check as i am lost...if i put a manual out of a series 1 vn into an auto series 1 vn i still need that adaptor? man can't imagine the back of the cranks being different as same motor but oh well

 

[azzfox]

yep need the adaptor. S1 auto/manual had different cranks, S2 auto/manual were the same.
