VY idle problems urgent help (solved)

[yoda69]

Have you updated the1's s/c vt bin to take into account you are using stock injectors?

[l67 vy]

sorry I mean stock l67 injectors. im trying to update my nvram with a fresh version but im also having problems with ose plugin so cant write to my nvram

[l67 vy]

here is a log with my car not running. the left hand o2 sensor is all over the place could one be faulty and the right is just sitting at 400 which is where it sits when running.

ive also got a fault on my dash it says to contact service repair. and now it wont let the car start at all. like vats is enabled yet it is not.

have you selected oseplugin in tunerpro? Does the enhanced bin text show up down the bottom? If you want to update enhanced to the latest version you need to reburn the nvram on a burner. You can't do this with flashtool.

Yes o2 sensors normally oscillate as they measure the oxygen content in the exhaust gas. The PCM controls the fuel mix lean/rich so it can maintain a centrepoint fueling 14.7:1

If the car will not crank then the BCM may not have received a valid signal from the keyhead so it has not enabled the starter relay.

ive got ose to work now it was a missing dll file.
it is cranking but not firing (sparking)
any idea on what the contact service tech message could me regarding?
it also has a lpg light on my dash yet my car has never been lpg. is that to do with the pcm I changed to?

You will get the service message while logging as the dash no longer gets any data. It will also occur if you have a VT bin on the NVRAM, the data stream is different on a VY so needs to have a VY bin on it. The LPG light might also suggest a VT bin on the NVRAM if its lit while not logging.

Spark is totally independant of the PCM, even with it disconnected you gets spark providing the CAS and ignition module are working. Check that there is power getting to both, might just be a blown fuse. Injectors not pulsing while cranking is VATS (and if logging you will see 0ms injector BPW).

The PCM is linked to the BCM for VATS, so now with a swapped PCM you will need VATS disabled if you want it to run or get the PCM linked by someone with a Tech-2. But sounds like you have had it running so VATS must be disabled already?

oh I thought because I changed to the memcal based computer I had to use the older vt base software. so i can write the1 enhanced vy bin to the pcm nvram? could you please give me a link for the correct bin i should be using?

VY_V6_SC_$07_Enhanced_v1.11.zip is this the correct one? as it is not the flash version

Here .. http://pcmhacking.net/forums/viewtopic.php?f=27&t=2518. And the VY V6 Supercharged bin.

You need an EPROM programmer to do this.

bugger so it wont work properly on the vt bin is that correct?
looks like I goto buy a programmer lol.
at least now I know what the problem is thank you.
is the does the vy bin still have all the tables that the vt bin has?
