Re: 93 1.6l Miata stock engine (for now)
As requested, here is more idle data. 1. CL timing only. Settings as suggested by andreika . CL_Timing_Settings.png Adding electric loads (low beams first, then interior fan) we see that the idle timing is increasing, yet the rpms drop from approx 1000 to approx 300 at the lowest point.

Re: 93 1.6l Miata stock engine (for now)
Did some more idling of the Miata. Please see attached logs/tunes. At various times I played with electrical loads and AC to see reactions to increase/decrease in load. The only part documented in the log is the AC switch, other loads can not be identified. Typical sequence of loads was: Headlights,...

I assume that's the TFI ignition system? Distributor with vanes and a hall sensor? No crank sensor?

Re: Looking for a solution for the Subaru EG33
Just for diagnostics, if you flip the two inputs, does the valve go to full open instead of full closed?

Re: 93 1.6l Miata stock engine (for now)
We need to have two tunes. One for MAP and one for MAF. This is necessitated by the double use of the VE table.
Once the idle issue is all sorted, I post two sample tunes.

Re: 93 1.6l Miata stock engine (for now)
Just an update:
The car is driving very well on rusefi now. Either with the built-in MAP sensor, of just the stock AFM (MAF mode). Idle is fairly stable. AC and all other things one would expect, work.
It's time to sell!
Anybody in need of a rust-free 1993 NA6 Miata in classic red?

Suggested Idle Improvements
Quick summary: We currently have two idle modes- manual and automatic. Manual is "pick a value and leave it". Automatic employs an adjustable PID strategy. For most modern-ish street-driven cars, automatic will be needed. The implementation has improved considerably over the last few month...

Re: MREAdapter48 pnp Miata MX5 NA
The board seems to be a success indeed. I went for several longer rides without any issues. We have a working tune using MAP and a somewhat working tune (needs a better spark table) for running MAF. Idle compensation (closed loop idle) seems to begin working as well. The engine hasn't self-stalled i...

Nice setup. Do you have any VD pulls? There's a guy near me who keeps supercharging NA Miatas (and subsequently blowing them up) and the torque curves he gets are just hilarious.

Re: MREAdapter48 pnp Miata MX5 NA
Not sure how far we're off, but the connector should be in the exact center between the front mounting holes (PCB to case, approx 120mm apart). That would mean approx 17.5mm from each PCB mounting hole.

Re: red 2003 VVT test mule Miata NB2 #27
It may be a voltage issue. NB Miatas have a weird signal-inversion behavior during cranking, especially when cranking more slowly. Cranking drops the voltage and that may cause some funkiness with the sensor. Try a bigger/newer battery? If one is not at hand, run separate power for the sensors (12V ...

I'm tidying up the routing on the board (a few days), there is approx 12-14 days from ordering to delivery, add the dropshipping time to that and you have it. I will update design status as often as possible.
