A bit of a thread revive sorry. How do I set the timing with a 'MiataLink'? (i.e. I understand you're no long able to use the jumper-connections as you would normally on a mx5 to connect a timing light) I have a miataLink but no handcontrolller. I can connect/log through the serialLink using the 'Data Log Lab' program. I also have the 'PCLink' software (v2.5) and a serial to USB cable through virtual COM port 4 but can't seem to connect to the ECU that way. In the Tuning instructions (https://www.flyinmiata.com/support/instructions/ecu/ECU_tuning.pdf), page 7, it states that you've got to match the CAS timing with the value in the ECU but only mentions how to access the set-timing mode through the hand controller. I marked the CAS position on the old engine before transferring it across but, silly me, a) marked it on the back of the engine where I cant see it and b. marked including the washer (which moves). Any ideas how I can connect to the MiataLink ECU so I can set/check the timing using a timing light?
