OK.. Ive been using the 16196395 /NON-CPI memcal and $OD mask and my bin file without issue for a couple years. I got some 16197427 ECMs and used my 6395 memcals with no issues and the $OD Mask. I got some 7427 ECMs in and the memcal will not work well with my setup. After examining the memcals, the ones I'm having trouble with are the ones with the blue and white netres chips (under the knock board). The Memcals with the black netres chips work fine. I also tried the $OE mask thinking maybe that was it, but it ran even worse.

The issue Im having is light and no TPS, the new memcals appear to turn off fuel, but run OK as long as your 1/2 throttle and above. Again, my bin file runs fine on all 1616395 non-cpi ECMs, its only when I install these memcals with with blue/white netres chips do I have a problem.

any ideas?
