Hello all, I cannot seem to solve for a code P1516 with the above operating system.

I am running a 2bar sensor and have scaled everything related to the MAP as indicated in the custom OS set up. MAF has been disabled and both fuel predication tables

The vehicle will typically set this P1516 when the follwing occur:

WOT
3800 RPM
343 g/sec
148Kpa

When I had it on the dyno I was able to make several pulls in 4th from 2500 RPM to 6300 RPM where the error would occur. I clipped the rev limiter to 6100 and was able to make several more passes up to the rev limiter without failure. After further testing today I made a pull in 4th from 3200 RPM and the failure occured at 3800RPM.

I am assuming that this is an airflow vs TP error. Using the Tech2 to pull the failure record, I see what looks like bogus data, 0 rpm, CMP - 300 RPM, which is odd.

Anyone else out there have any input?


Regards,

Scott
