MS3X no start with "Miata 99-05" mode
 

New MS3X on 94 motor with VVT head.
run ok with 4g63 mode with stock CAS.
switch to Miata 99-05, no luck.
CKS and CMS works.
No idea how the trigger setting work. please point me to the right direction.


attached log file from composite logger and tune.


Please help.

Thanks

Are you using all NB sensors?

cam sensor came with the head so i suppose it's stock nb sensor. crank sensor from DIYautotune.
trigger wheel was from a 323. which look the same as the NB one.

it appears to be syncing in that log you sent, cant you post a screenshot of the composite log? i cant view it in software here. you probably just need to fine tune your crossoverpoint pots.

thanks.

looks like you're syncing.

so the sensor and the trigger is installed correctly?
what i should play with then?

is the green line suppose to be CAM?

oh yeah. looks like you have your sensors reversed.

Per your log, you have your crank sensor wired to your cam input and your cam sensor wired to your crank input.

yes. i finally notice this problem and I just killed my starter........

new starter installed. wire swapped. Started to combust but still no start.
I can start the engine in 4g63 mode, so i suppose the fuel figure should work in miata 99-05 mode. <-- is this correct?
i hooked up the timing light but it didnt work at cranking speed. how can I get the base timing right?
What else can I go wrong?

For the "Ignition Input Capture" should I use Rising edge or Falling edge?

here is another 2 log.
I got combustion but it didn't start.
is there anything to do with the "Trigger angle/offset" ? I set it to 0
also I haven't connect the vvt control. will it affect?

video clip of my cranking

I can't view your trigger logs on my desktop at home, but you're still not syncing.

Its still not working. I have no idea what to do. Is it the problem of the hardware adjustment or its the software tune problem?

I custom made the sensor mount. Do I need a calibration ?

Your cam and crank inputs are still wired backwards. It's not going to start until you fix that.

arrr.. OMG.. i made this mistake again.... Sorry, i will fix it and mark the cable tomorrow.
