hmm CNPJ seems to be different, it read 362, maybe it's not an E variant.

CDUZ3954
CFZA8278
CJDP1932

All read 406

If the others are 406 that would make sense and workout more ball park than 362

Try $A6C with cfzf for 355 I think that was around 400 as well I think

looks like it's possibly offset, Some of the HSV ones are the same, Try 4568 hex instead of 4566.

in tunerpro, right click Base Injector Rate - msec/gram and select Edit Parameter XDF info, change hex address from 4566 to 4568

That seem to bring it to fall in line with the other xdf and bins must be a stuff up in the xdf

possibly, if you have a look at some other things like shift points there out as well, so could be a number of things.

Hmm I wonder if it's safe to use that xdf and bin. It's the only one that had been modded for rt

in the xdf header it's got

$A6 Variant E: VT Commodore Holden V8. Should work with the following bins: CNPF, CNPJ and CNPK.

So looks like it was made to work with those bins, the calc is right for the base injector scalar so to me it looks like a few things in the xdf need to be offset by 2, im not a xdf expert though, the other guys would be best to check with. But compared to other bins it seems that way.

The real expert is actually away for a week, but I'm sure he'll look into it when he get's a chance when he gets back as it's all just a matter of having the right info & making sure the info is correct to write the xdf to!
