VS Auto to Manual PCM Hardware Conversion

Post by V1704 »

Hey guys, been lurking the forums for a while now, but only just signed up.

I'm planning on putting an l67 out of a vs series 2 statesman into a vc commodore (and putting a T5 manual behind it), and am up to planning the computer side of things.
I've read up a little on the physical differences (or lack of hardware, however you would like to see it) between the vs auto pcm and vs manual pcm, but don't feel confident in making the changes to my auto pcm myself.
Is there anyone who still actively changes these for other people? A lot of the threads I've found are several years old. I'd also be interested in having my memcal tuned to remove VATS and add manual flags while going about it.

If this is in the wrong area, please let me know.

Thank you,
V

The VS L67 auto PCM will run both transmissions.
Just re work your engine loom to suit the manual trans and update you calibration to suit.

Isn't it the VT pcm that accepts both? Don't I have to change the board like so with the VS pcm?

VS Ecotec came in manual. Same PCM as L67.
You haven't stated what trans or speed signal type you're running.
If you're running a Hall Effect signal I still believe the Ecotec PCM will take both. There's a thread on here about this.

Hey, sorry, I've posted similar questions on a few sites so I forget what info I have and haven't posted.

It's a the factory pcm to match the series 2 vs l67 (pink plug barcode starts with 33806L), so according to this site it should only have the hardware to accept the auto signal?:
http://www.kalmaker.com.au/phpbb3/viewt ... ?f=4&t=800

Behind it I'm putting a T5 manual box and having a new speedo cable made to have vss output and a mechanical cable output. I've been told merely changing the tune won't be enough with my pcm, since the computer will still think it's auto (if I use a sine wave generator for the output)>, so I should use a hall effect signal generator and have my pcm modified?

I want to retain the factory vc speedo, so I'm trying to work out what the best way to match up the T5 transmission, and get the memcal tuned, etc.

If I've missed anything or more info is needed let me know please.

Thanks

Righteo, thanks for all the replies guys and sorry for the slow one. Finally got down to the shed today and popped the ecu apart. Judging by this pic and the links you've supplied it looks like I've actually got the bits on the board I need for a the manual input, yes?
So I should only need to tune my memcal to delete VATS and check the manual flags yes? If I get this done will I need to get a Hall Effect signal generator? Or will the computer be okay with a sine wave VSS and manual flags checked? I've been told it chucks a hissy fit doing this.

Thanks all, if I've missed anything please let me know.
