No it is not possible for the P59 PCM to emulate a P01 12212156 bin. You would still have to fit a RTLS1 daughter board to your the P01 PCM.

Moving a RTLS1 daughter board from a P59 to a P01 PCM is not practical. Sorry to have miss led you.

RTLS1 daughter boards are available. Have sent you a PM.

I know this sounds like a simple fix. But with all your playing around there is the possibility that the spark plugs may have become wet and shorting out your spark plugs.

Maybe Bubba can confirm my findings.

I am not familiar with the Express van. If it is using a P59 PCM and a 12587603 bin then RTLS1 would be compatible with the Express van.

If you wanted to hold the engine on a particular RPM like bedding in a cam, the RTLS1 would be capable of doing this by adjusting the idle RPM cut-off speeds.

Yes that makes perfect sense.

Still going with this problem.


Oxygen sensor voltage seems way too low.

Have you used any Silastic on this engine any where. Maybe the Oxygen sensors have become poisoned.

There are some very cleaver people on this forum.
