Just fired the tbi 454 for the first. Have run in the cam and one short run down our lane. Seems good, maybe a little lean at low speed steady throttle.
it is a 6395 pcm with BHDF bin
advanced $OE TP5 v 250.xdf
A220 trans 2 $OE TP5 v250.adx

i am using tuner pro rt
i have updated the USB serial driver
i am getting no connection
i realize the engine has to be running to get useful info but does it have to be running to connect. I have only tried it with the key on. I don't want to have a new motor just sitting there idling while I fool with connections. If need be I will have my wife drive the burb while I fool with connection if the motor has to be running. If anyone wants to jump in with step by step that would be good.
