MSpnp pro for 90-93 for vvt swap issues
Dear awesome community,
Im in the end phase of my vvt swap for my 91 miata. After having blown countless fuses I got somewhat of a progression. I've cut the 5v, ground and signal wire of the tps and the cam and crank signal wires. Then I connected these with a 16 pin connector (connector 3 on the ecu).
ecu with 16pin connector connected
Now with connector 1 and 3 connected the tps works fine and no fuses blow. But I do not get any signal from the crank or cam sensor (tested with the composite logger)
I will check this evening what happens when I connect connector 4. presumably F2 blows because thats what kept happening.
What might be causing these issues ?
Very kind regards cedric

Well,
After following all the steps in the instructions on how to instal the megasquirt I loaded up the basemap for the vvt engine which is from an 03. I used the VTPS from that engine aswell. I wired the tps wrong and thus blew the fuse. I rewired the tps and now its working. But as soon as I plug in the bigger factory plug, a fuse blows on the ms3 board

why did you do it that way?
I would have brought the vTPS in through the OE TPS wires, and the crank/cam via the CAS connector.
are you trying to have the MS provide the 12v to power the crank and cam sensors???
