Hey all. finally got a new fuel pump in the coupe, hooked it all up and am now trying to chase this non running condition. I didn't install the Microsquirt and I have no idea what I should be looking for, just that i needed a datalog.

Up until now, it hadn't been starting. Thought it might have been the fuel pump relay, but that's good, then I found a fuel leak so I replaced the lines and replaced the in tank pump with a DW200, bypassed the onld K-Jet main pump and accumulator. It's now firing off just fine, but then wants to stop after idling breifly.

PLZ HELP lol.

Once you get the electrical back, check the MAP sensor wiring. From the log, it seems to be meandering up and down with no relationship to what the engine is doing. You can just turn it on without trying to start, and then watch the MAP gauge on the dashboard. At sea level, non-running, it should be rock steady at ~100kPa.
