Title: Tuning Tools
Post by: Brute on August 02, 2012, 02:11:35 AM

Had an older Digitron I sold, have a FAST air fuel meter I use for 4 cycle stuff. Thinking about a new Digitron but thought I would ask what tools everyone is using for tuning? ?Seat of the pants? is an answer, but I want numbers and graphs I can see what is going on and why. Reading plug color and other basic tuning methods work, but sometimes do not tell the whole story. Whatcha got?

I will be using a Mychron 4  HUD for my KX500 kart build, i'm anxious to see how it works.  It does EGT's coolant temp, rpm's and in depth lap datalogging. Pretty cool unit!

I too am looking for some tuning tools.  What is the relationship between the CHT (Cylinder Head Temp) and Coolant Temp?  Which would be better to monitor, with EGT of course. 

MOTORRAD:  Do you have a picture of how you mounted the Digitron to your bike so we can see the relative size of it vs the bars?  Also do you have any pictures of the CHT sensor and EGT sensors installed on the bike?  I'm mostly curious about the location used for the EGT, I've always placed it as close to the exhaust port as possible.

Finally, what EGT's do you guys tune for??

Please and thank you  :mrgreen:
