32 is a confirmed sync loss due to improper crank/cam timing.
Does it occur often enough to catch it with a composite log? |

Graeme sent me this pic of the mod he had to do:
https://www.miataturbo.net/attachmen...ine=1350026153 I'm watching google vids on soldering circuit boards, kind of a shitty way to start out learning how to mod this stuff. |
I should have just bought that Bugatti instead.

get some vodka and burn it.
|
Can someone please help me and and shoe me what a composite-logger sync 32 error looks like so I know when I have what I need to proceed? I made a few logs this morning and can't tell if it's happening or not.

I have a spare vvt valve cover if you need it. Fatkao might have a spare head off his first vvt motor, try pming him if not let me know and I will call him.

Here are a few logs that all have sync loss and I can't tell where which I found on the interweb from various cars:

Damn, I'm dumb. |

I feel like they should all look like this if a 36-1 and a single cas tooth. some you've posted look like a 4-2 |

That's because I can't find a composite logger with sync loss. Any thoughts on going with a tighter tolerance on the CKP sensor?

Have you changed the ignition mode to Miata 99-00 in the MS?

What is your tolerance at now?

Stack feelers, then add their thicknesses.
Either way, you should be able to tighten that to ~.030 without any adverse effects. Make sure the concentricity between the crank and trigger wheel is good, though. |
Oh man, stacking feelers...this is embarrassing. I'll get out in a little bit and try this.

Screw that. Credit card thickness. If you can pull a credit card through the gap with a slight drag it should be good.
Two hotel cards is too big a gap. I was having problems till I closed the gap to 1. |

I just looked back at my thread. I was getting error 32. My ckp gap was 1/4". Closed the gap to single credit card thickness (gap from tooth to sensor), and the error became less frequent. But what really fixed my problem was going from rising edge trigger to falling edge. Your input circuit setup is possibly very different from mine though. I'm running Frank's implementation of the NB input circuit. |
I tightened up the tolerance on the CKP sensor and I have about 45-minutes of logs with 1 sync loss event, #31. I am set-up on leading edge. Should I be concerned or switch to falling edge?
