Hey folks,

I've finally got my 90 Daytona running and I've been trying to get Minidash going to get baseline data before I convert the car to E85 and pure alcohol.
My issue is I keep getting the no coms error. I know I'm doing something wrong and it's probably a simple detail.

Here is the break down. The car is a 1990 Daytona ES T1 automatic. I'm using a Palm m130, cradle, Radio Shack null modem adapter part #26-264, schmart board Populated RS-232 SchmartModule, and Minidash 5. I've tried switching the TX and RX signals and don't get any change.

Do I need to mod the ECU with a custom tune before it will allow the comms to work?
