OK. I went ahead and bit the bullet and ordered PCBs for the currently available parts.
I did make once change, that, maybe 5 people may care about. A added pins to connect an AEM 30-2064 type Exhaust back-pressure sensor kit ( or, roll your own ). So, those interested can have fully compensated AFR and, log the exhaust pressure as a custom PID. Mostly useful for pre-CAT and pre-turbo installations.
