Your trigger angle seems to be at the base PNP settings.

Did you go through this procedure:

Go to the Spark Settings menu and set Fixed Angle to +10.
Adjust the Trigger Angle until you read 10 degrees with a timing light.
If the trigger angle needs to be less than 50 degrees to get your base timing right then set trigger angle to 55 and instead adjust the cam angle sensor to set your base timing, just like adjusting timing on a stock Miata.
Then set Fixed Angle back to -10 to enable spark advance.

The only way the car is driveable at all is if the timing is advanced 20-25 degree's, when it is advanced the car drives like a normal car other than a bucking or bogging issue between 3,000 and 4,000 RPM.
1. You can't "hear" backpressure

2. Are you even setting the baseline back to -10, from 10? If you leave it at 10 the car will run like ****.

Zip your entire MSQ and post it.

i think +22.5 is PNP specific, but when I set my trigger angle I used that setting. Go by what your timing light tells you when setting the trigger angle.

Then verify that its correct by changing the fixed angle to +10 and hooking up a timing light again.

well i gotta wait till dark to do so, my timing light isnt bright enough to do during the day nor in the shade.

but i timed the car last night the correct way and left it that way, but tonight i will do it againt to make sure, it could have changed when changing the setting's.......

anyone got any opinions on why it works when the Trigger Angle Addition is ajusted to 0 ?

Other thing I noticed in your msq is EGO Control is not setup right, you said you have a wideband. Have you changed the settings in configurator as well? Change authority to zero while tuning VE map, unless you're using MLV.

What map are you trying to use? Is it just Jerry's basemap?

Check your timing again. If you are running Jerry's basemap and the car will not rev, but it revs if you advance everything 10 degrees, something's wrong with the timing on the car itself. Check the orientation of the timing belt, ensure that your TDC marks are *actually* TDC marks (pull the plugs, spin the motor to TDC, compare marks), and ensure the timing belt is set correctly.

ok, ill check the belt but i dont think it skipped a tooth because the car ran fine on the stock ecu and Emanage Ultimate.
And i timed it before the MSPNP and it was fine.
