LS3 and Vintage air

[mikeextrafast]

I have a LS3 in a 69 Camaro with a Texas Speed cam , during deceleration with the air conditioner on the engine wants to die sometimes, what provisions are you guys making in the tune to keep this from happening

You will most likely have to adjust your idle minimum final airflow tables to compensate for the additional load. Depending on the cam you may have to raise your idle a tad as well.

I am not a great mechanic or overly smart but might it have something to do with the car being upside down? That might put additional pressure on it somehow? :) had to sry :)

[dirty rick]

Is your ac connected to the LS3 ecu?

No. The E38 and E67 ECUs don't have an "a/c request" port. That request has to come in via CAN serial data.
