Default MS3 Naturally Aspirated Tuning Data

Just thought I'd share some tuning data with you guys.
This will be nothing new for the majority of guys here but some of the Newbies might find some of the information useful.
Data is from tuning my MS3 on my Naturally Aspirated Miata. Details of DYNO and engine specs are below.

Procedure:
I first tuned the base map for an AFR of 12.5 trailing off to 11.8 at red line (similar to stock).
I then set timing back at the WOT cells -10 and did a sweep.
I continued to perform sweeps by adding +2 or +3 degree timing until I saw no more gain.
The results are the following:

Megasquirt Data was exported via CAN bus to a data logger and synced with DYNO data output via analog signals.




A side note:
I also ran the stock ECU right after I tuned the MS3 with the exact same intake, exhaust and ambient conditions.
I was able to pick up about +5 whp and +5 Ft-lb with just the tuning changes over stock ECU.



More data used to confirm AFR and MAP was consistent throughout testing.





Next stop, Turbo!
