OK. For anyone who wants to try it, I just completed a serial data mod re-flash for the AEM 30-0334.
It increases the polling interval to 20ms ( 50x per second. Or 5x faster than "stock" ) and adds an extra full digit of resolution. So, it turns the serial output into actual usable data
I tested it with VCM Scanner 4.4.4 and all looks to be good to go. For any who want to try it, I'll toss in a few extra connector pins so you don't have to hack up your wiring harness. Enough to add the serial and 0-5v wires to the OBDII harness.
