Questions about portable afr and knock dection

My question is what two systems should i invest in that will do it all cause i have a and old tractor i do some sled pulling with its carberated and point distributor i would like to somehow data log the detonation to try to optimised the afr and igition timing to try reall make it work good on the track plus also use the two systems for all my other tuning projects?

hello there are so many good systems on the market for knock I really think the plex system is one of my stand-alone favorites ad for ease of use the innovate is very versatile although they can be a little hard on sensors if left powered up when the engine is not running and need calibrating a lot

they do however offer recording and other inputs like rpm tps etc that can be downloaded to PC which is a great advantage

Thank you
