The good thing about megasquirt based thinking systems is the ability to post data logs. It would allow us to see what is actually happening while the engine is running. The Pimp is the best my consensus...but my mspnp2 is decent, too. I'm very new to all this and a91what has been a huge help.
I used to run moates quarter horse chips... but after running into several people ( including myself ) with actual ECU circuit board issues I ditched the 30 year old computers.
Also, I've seen people constantly dropping hundreds of dollars to sct tuning shops and still have issues.
