As a starting point, if you're running sequential fuel, change it to semi-seq. If you're running sequential ignition, change it to wasted COP.martysport wrote: ↑Wed Nov 20, 2019 4:31 pmI have the exact same problem, running spot on this morning I flashed the new firmware and now it won't start (no RPM issue) I'm using a 36-1 wheel and single tooth cam.noisymime wrote: ↑Sun Nov 17, 2019 11:37 amryan_pajero-io wrote: ↑Sat Nov 16, 2019 2:46 amengine can not start up there is no rpm
the problem has been solved
i replaced "decoders.ino" and "decoders.h" in firmware with version 201909. the engine started up as usual.
my engine uses a 60-2 crankshaft trigger wheel and a single tooth camshaft wheel
Do both of those, restart, then see if you get an RPM reading.
As for the cam signal, make sure you've got your jumpers set correctly for the secondary input, then run a composite log.
This 201911 version fixed an issue where the missing tooth decoder + cam would sync up before the cam signal had been seen (if running sequential). If you're not getting any sync with the new version then it could be an issue with your cam signal that is getting hidden by the issue in the earlier firmware
