Is my car running slower with the datalogger connected?
This is on an '86 MAF car with the '165 ECM. I built the standard two-transistor cable and I'm using Craig Moates' software. The cable is designed with a 10K resistor between ALDL ports A and B -- I believe that's to enable the faster transfer rate.
With the cable hooked up (and the resistor between A and B), when I give a slight throttle burst at idle, the car stalls. This doesn't happen with the cable disconnected. We're only talking about 2500 RPM here.
Clearly, my car shouldn't stall if I rev up the motor. My air filters are clean and the car is mechanically sound. Why am I experiencing these symptoms? Is it possible that my car isn't reaching its full potential when I have my laptop connected?
