REALTIME VX-VY n/a PCM

[The1]

Looks like all the pins are there except OE and CE A15/A16, which would be fine to jumper across i think there just high/low when reading and address lines. Now to make up a adapter board to plug ostrich straight into the board.

[Tuning vx]

I know this is a old post but did anything come from this? I have a n/a vx and I'm learning how to tune with tunerproRT and would love to be able to real time tune rather then having to unplug my ecu plug in the bench harness and so on.

Is there a way to real time tune the vx or should I just get a loom and ecu out of a different Holden?

Please can someone simply tell me what it is I need to do so I can just follow your instructions.

Thanks in advance

What are your skills like? I think while its possible, its just way to high barrier to entry for most people, and logging data, reflash cal is enough for most people. You could convert to a VT computer and supercharged enhanced bin, then use a pcm nvram, but you'll need a lot of loom work for that too.

So to do it on the VX computer you'd need to wire those connections above with really short cables to a socket with the pins connected the same as the socket in the earliers pcm, add jumpers for OE and CE pins, then get a pcm nvram and plug it in without damaging anything and either make it fit in the vx case or secure it without the case / make a new case, then I guess load a normal flash bin the the nvram and see if it runs the car and talks to your pc, and if it does then you'll need to ask the1 for the realtime VX/VY bin.

You can flash it in the car rather than taking it out.

I find most of the time ill do a log and take my time looking at it to then go back to the car a few days later to flash a new Bin and get a new log.
On the dyno and some idle and cruise adjustments would be perfect for real time bit its not a deal breaker.

I would defiantly look to implement real time if it becomes a reliable option.

Just note its safer to do a write cal, not bin, as it does not need to re-write the whole pcm then, and does not risk the boot sector.

Well made an adapter according to this website wiring of plcc to ostrich. Have tested each pin from ostrich straight through to the adapter but ostrich will not work, upload bin, set to bank 8 but pcm wont fire up, put a eeprom in the socket and pcm fires up straight away. So im out of ideas atm.

I thought the ostrich was only able to use a 32 and 64k size memory?

I’ve used mine in a VT with the Moates G6 adapter without a problem and there a 27C010 chip which are 128k bins. I think you can even use a 27C040 chip with the G6 adapter and switch between 4 different bins.
Not sure if there is anything special about the G6 adapter.

Yeah not really sure about the G6, but that could be a thing, or the same wiring. And I know ostrich is funny about the wire length, so with this, a little shorter than normal wouldn't be a bad idea if possible.
