General ? about your spark tables and how they graph out.
I've pretty much finished up my fine tuning of my spark tables (for $8D TPI) but is relevant to all.
We I look at the graph in Tunercat, it graphs out real smoothly across all RPMS up to about 50-60 KPA, but from 60+ KPA for 2000+ rpms it looks like the Rocky Mountains with many high and low points all over.
The most timing is down the 50KPa line and the highest points at 2000rpms and 4800 rpms.
*
Is this "Rocky Mountain" type graph typical or should it be smoothed out with nice curves all over?
(I believe the AJUP?? chip that was to be stock original was very rough like this to start with also)
Thanks

Forget what it means to you. It's the engine's opinioon that matters.
