I ask because I remember the kits back in the day that used a resistor to change the maf reading so the trans would shift firmer and that your product somehow changes signals to keep AFM disabled.
Mr. Pogo:
No. We do not interrupt any of the current communication. There is a protocol to follow when communicating on the bus and we follow it. If you don't know what you're doing, you'll get check engine lights and transmission issues.

Hope this helps...
