Here is a video capture of a TS dashboard when I was sitting still, tried to rev up to 3000 rpm and hold.

[video][/video]

I did a quick test with the DSO to capture the two igniter signals that are driven from the Frankenso board, rev'ed to about 3000 rpm sitting still. igniters.jpg Here are more pictures when I was out driving before this and only looking at one igniter signal. igniter2.jpg igniter3.jpg It looks odd t...

I'm back home and can do more testing tomorrow. I have a simple 2 channel digital storage oscilloscope and a 2 channel analog oscope. I can look at spark signals on the board, and maybe try to couple to the spark plug wires and look for weak sparks. Any suggestions on specific tests to run? I may be...

One time I noticed hesitation is in the video just after 1:28 after shifting to 5th gear. You can see the spikes in AFR when I shift, but after shifting to 5th there are two more little spikes. It seems like it was more than just those 2 or 3 seconds though. I'll do more testing on Saturday after I ...

Yes, I do have an SD card on the board capturing logs. I didn't watch closely enough when the hesitation happened. I have a video from some of the testing and I put it together with a capture I did of the TS gauge view I got from @thommm, I don't see an afr spike when I think the hesitation happened...

I now have idle control, map, tps, speed density tuning settings based on @thommm's smurf tune, and I drove about 20 miles on it testing and running TS auto tune. It's running very well now. Thanks, Thommm, for sharing the tune!! It is still running rich at idle and a little rich overall. And, I get...

After updating to 6/18 firmware calibrating tps shows sane results for 0 to 100% rather than 100 to 0. TPS report is good now

Well, now https://sourceforge.net/p/rusefi/tickets/199/ is also fixed. When calibrating TPS, the settings appear to be "backwards" What is the correct direction for TPS voltage sensing? I wired mine to be about 0v for closed, and 3.25v for wide open. Mine shows backwards in TS now, and I ...

Oh, there is a coolant thermal switch and ECU can control fans also on pin 1R.

Yes, it did seem that I was not running on all cylinders.

After changing the injector outputs, I'm running much smoother. I also enabled MAP and WBO2 inputs today, and I leveraged @thommm's smurf tune.
Now running very smoothly!

That run was semi-warm. I first tried it warmed it up on stock ECU and it failed. I realized two hours later that my swapping out tuning files disabled injectors. Engine had cooled to about 104F. I tried again just now cold (87F in Texas), and it started up easily. Still runs pretty rough though. An...

Another day, another Miata running rusEFI! :D I picked up the latest firmware and applied @russian's tune for a rough timing and fuel map. She started!! [video]https://youtu.be/fDH2gNRHDS0[/video] Still need to get TPS set up correctly, idle control, etc., but it starts now. Thanks for the help guys!

Ok great. Congrats on #20. I'll try new firmware tomorrow!

It's weird, I never saw it do that gap in timing before. Maybe it's intermittent?

Yes, using stock AFM ,vane type. I just tried manually pushing in the vane, and I can hear the fuel pump turn on/off. It is not very loud and too quiet to hear when cranking. But after doing that and trying to crank after the fuel pressure was up, there were a few puff trying to catch on to start. A...

Thanks for the tips. I swapped back to the stock ECU to verify things are still ok, and it started up fine. I rechecked the injectors with benchtest and can hear them clicking on both channels. I tried cranking with different values of advance, and there are no puffs at all that I can tell without t...

Yes I have injectors set to IM_BATCH, and plenty of fuel in the tank. I tried spraying in some starter fluid just now and it almost started. The stock AFM has a switch to enable the fuel pump. It looks like no additional wiring or signal needed. The car starts fine on the stock ECU, so AFM should be...

I'm trying see what is different with your configuration and mine (1990 1.6L) which is not starting yet. The main difference I see is you wired the igniter drive to 12v rather than 5v. I checked the signal on the stock ECU, and I see 5v pulses. Are you using the stock igniter & coils? Thanks!

From Drive, I was able to save Thommm's tsproj file to my own google Drive, then download the file from there. The file is actually a zip file. I renamed it to Smurf.zip and attached it here.

Thanks, Thommm, for the very helpful write up on your configuration!!

Thanks, @russian, I can make sparks on all the plug wires now from bench test, but I am still missing something basic. When cranking I see both trigger input led's flashing and both igniter output LEDs flashing, but I see nothing on the timing light. After I stop cranking I see one flash on the timi...

I have made some progress but still seeing some problems. On igniters, I can see LEDs flash from bench test on both lines. And timing light confirms sparks on the plug wires. When cranking I see LEDs flashing only on first ignitor channel. On the bench, running self stimulation shows the same, only ...

Hi, and congratulations!

I am getting closer on my 1990 1.6L Miata.
I would really like to see what settings you are using for trigger and ignition.

Good to see the driver vertical and the car in one piece!

Here a shot of timing after wiring up as shown in your pictures above.
How does this look to you?

I plugged the board into the car and so far, CLT, IAT, and MAF look sane. Still working on hooking up MAP and TPS. Can you check the wiring updates I made to the Miata 1990 page. I put question marks on the pins I'm not sure about. http://rusefi.com/wiki/index.php?title=Vehicle:Mazda_Miata_1990 I th...

I tried again with type 41 and didn't get the error. Not sure what I did. Did you install a MAP sensor? I got an mpx4250 and planned to put on the board. Any restrictions on the proto area to use or not? Also, I got a variable TPS. I want to be able to run with stock ecu. Do know if it can be wired ...

I'm going to start on this car now after getting the new Frankenso board. I have been working with the old Frankenstein board on my 96 Miata ( http://rusefi.com/forum/viewtopic.php?f=3&t=666 ) for a while. This board looks great! I'll update the 1990 Miata wiki page as I go: http://rusefi.com/wi...

Yes, it was being set in TS. I didn't think to look there.

Here is the error message with updated firmware:

FATAL error: ADC mapping error: input PA7 for AFR already used by IAT?,

Where is IAT getting set to use PA7?

I'm trying to hook my wbo signal to afr input on pin inp10/PA7. After assigning the pin in TS, rusefi shows the error:

FATAL error: ADC mapping error: input PA7 for AFR already used?

I thought that input was unused. Any ideas?

Oh, I see where I found the picture from this thread:
http://www.miataturbo.net/megasquirt-18/lets-discuss-spark-advance-69662/page2/

and a comment there says "The load scale is next to useless however."

Maybe someone can translate the Japanese?

I found this stock timing table for miata 1.8 awhile back, but have not tried applying it yet. Does this look correct?
