Leafy is there an easy way to try starting it in batch fire? The crank has a TDC notch right? That way you don't need the cam sensor input. So it takes a little longer to start initially and you don't have seq inj or ign. It's a track only car that doesn't rev to the moon, batch is fine. Oh, and you're not using the VVT anyhow, right?

I don't think these coils could keep up firing twice as often at 8k rpm.

Help me out on the math here but I'm getting 7.5 milliseconds at 8000. How much dwell do they need?

And I'm not suggesting not running a CMP at all, just not using it for now to get the thing running. Figure one thing out at a time and all that.

And I read the post again,it seems as if you are running VVT?

Yeah 7.5ms is what I get but 3-4 and then another for the spark doesnt leave much time for it to cool down. I am running VVT.

I got the NC miata crank wheel and also a 2.3 duratec cam sensor so now I can have VR for the cam. I just need my free sample of Belden cable to show up to wire that. But once I install the crank I just have to modify the .ini for TS to allow me to see the Mazda6 2.3 encoder and it should run. The VR sensor is just because this hall effect sensor already seems borderline with the MS and its only going to get worse as it heats up.

Understood, duty cycle at 8k will be close to 100% if you needed 4.5 ms of dwell but that's for a couple seconds at a time and not on all autox runs. At least for me.

I think the cam sensor issues on the NB engines has been figured out to be a connector problem by the Spec Miata guys. We were having the issue and did the SM fix and so far so good. Will know for sure when summer arrives.

I think I confused you getting rid of the balance shaft for not running VVT. Or somehow thought the Ford engines didn't have VVT. Anyhow, glad to hear you are using VVT. And that it will be running shortly. And looking forward to seeing it in Lincoln.

Nah, the cam sensor issue is definitively a lack of delta-v between the states of the hall effect sensor. And the MZR hall effect was just as bad, so I'm avoiding all that stupidness. a VR sensor will never let me down.

Tell me more about this connector fix.
