Need help connecting TunerproRT to 91 firebird 5.0L auto

Doesn't TPI ECMs require the 10K Ohm resistor across pins A and B?

Not if they're using the 8192 baud ALDL they don't. For example, my 90 Corvette is TPI and does not require the resistor. All depends on the ECM.

EDIT: Looking it up, the 1227730 is pretty much identical to the 1227727 from the Corvette, so no, I highly doubt he needs the resistor for that ECM.
