92 Miata no Spark - DIYPNP
Car: 92 Turbo Miata 1.6L manual.
Problem: Will not start with DIYPNP MS2. Car starts with stock ECU.
I am getting fuel but no spark when checked with timing light or with in-line spark test bulb.
When I do the Output test for coil in TunerStudio (TS) I hear some tapping sound in sequence but timing light shows nothing.
I do not see RPM move while cranking in TS. The only gauges that work is Fuel Load and AFR because I have AEM Wideband.
Am I suppose to wire the CAS signals to DIYPNP or they are already in the pin-outs in car harness because I seem to find all kind of different info online which is confusing me even more.
I have uploaded my msq file.
I followed installation instructions here:
DIYPNP MegaSquirt installation for the Mazda Miata

Was your project in TS setup for microsquirt and not megasquirt?
When I open your MSQ I got errors that suggested your project is not setup properly. If not, TS changes a bunch of Input and Outputs to ones that make sense on a v3.0 Mainboard and not a Microquirt module. This would prevent the unit from working properly.
for example, sparkout was set to D14...which is not a DIYPNP output.
Fix your project properties by hitting cntrl+p, go to settings, and select "micosquirt module" under the megasquirt selection.
Then reload the basemap (NOT your map you uploaded) and try again.

Error loading base map
I started new project and when setting up I clicked on Detect ECU and it came up "MS2Extra Serial324"
Then I selected the Microsquirt Module DIYPNP under Settings tab.
When I try to Open the base map (91 miata 240cc injectors.msq) that is provided at DIYautotune I get the following error:
Signatures do not match!
Tune File signature:MS2Extra Rel 3.0.3s
Configuration signature:MS2Extra Serial324
Do you want to load it anyway?

I don't think I need to jump these for 1992 Miata because I didn't do that on my v1.5 board?
"Using only the first two jumpers as in the above image would control a 4cyl wasted spark configuration, such as controlling either one 4 tower coil pack, or two dual tower packs. This setup would use only outputs S1 and S2."
