I'm struggling for 3days now a basic ms3 whitout ms3x board, I can get a 4V Spark output signal, what the miata normally has, I reach max 2,8V and the spark isnt strong enough, and the car also wont start.
Standard miata ignition 10ms/1V ch2:
The Board(EGT and Launch on proto not wired in)
The test signal generator, do I apply normal 5v square waveform to VR-IN?
I also cant measure any signal on JP2 pin 9 and pin 12 where normally, the ignition come out(doesnt matter if Spark output MS3X or Led) , however on the J1 pin 1-2, can catch an injector signal, when Main Fuel Output: MS3X ON. How can I get the signal for igniton, what should I turn on in Tunerstudio?
The circuit wired for VR, I played with the R52 and R56(what is correct setup for this?), like on Frank Westfield Mx5 webpage and checked with multimeter and scope the signal and I also got a signal generator. Or should I use the Opto circuit?
I got a 1994 1.8 NA miata using stock coils, I also got now an NBFL coils.... Built after the Franks website 90-97NA MS3: 90 ? 97 MS3 | Frank's Westfield MX5 90 ? 97 MS3 |
