Horseless-carriage Posted May 12, 2024 Share Posted May 12, 2024 Does anyone in the LA area have a pectel t2 programming cable I could use? Happy to drive to you. I have a 1999 caterham with a 2.0L zetec engine with a pestle t2 ECU and need to calibrate the car for a new TPS sensor. Any help would be appreciated, thanks!

Horseless-carriage Posted May 13, 2024 Author Share Posted May 13, 2024 After a few attempts I was able to fabricate my own cable. Figured I should share the wiring schematic here because it was difficult to find online. I used a bestbuy insignia usb 2.0 to RS-232 serial adapter (with prolific chipset) because my laptop did not have a dedicated serial port and got some 1/4 stereo headphone plugs from guitar center. serial port pin 2 - receive data (RXD) pin 3 - transmit data (TXD) pin 5 - ground (GND) 1/4 headphone plug tip (far end) - receive data (RXD) collar (middle) - transmit data (TXD) base (close end) - ground (GND) 2 1 Link to comment Share on other sites More sharing options...
