Old hard parts guy, ECU, TCU are still a mystery but learning! When I hook up my clone of a Launch that is a clone of others, I sometimes download good readings, other times failure. Launch GoLo Bluetooth module. Last night looked at PIS. 1st attempt showed 4.47mm. 2nd attempt, all subsequent readings, were 163.58mm. Not good. 2001 360 F1 spider. ECUs 2001 software, TCU latest 360 Fi version 211023. Reader will show the module as 211023. Software version etc. Allows 3 gearbox versions. Not consistent which version works and what does not. Does the data all read through the ECU or does the data download direct out of the TCU? Could the different software versions be part of the issue? Updated TCU thru old version ECU?
