Dyno tuning with PCIII

Hopefully I will have a chance to do this in a couple of weeks.

I am looking for any suggestions/experience from those whom have ventured before me. I am currently running the canned tune for the Jardine hi-mounts, but have since removed the flapper and not done anything with the tune yet.

Thanks,

Sean

Complete the PAIR mod and buy the soft rev kit from Scotts mc supply before you do....you will be happier!

The only thing you have to be concerned with is getting a dyno tuner that actually wants to take the time to do the job right instead of just taking your money. Otherwise you are literally better off with one of the off the shelf maps from Dynojet or one of the custom maps on my site.

There are only about 3 or 4 dyno tuners in this entire country that I would trust to send a friend to and know they are getting a proper optimized mapping. I've seen even big name tuning company's charge a small fortune and then just install a canned map on a guys powercommander and I have seen fraudulent dyno charts as well... To this day I am still amazed at how many so called dyno tuners STILL do not know the proper A/F ratio for an RC51 and end up using the conventional A/F ratio for most other bikes which yields a particularly mediocre map even if you do every other step of the process perfect.

So, what is the correct A/F ratio for an RC? I need to get my bike tuned and I want to be sure that the tuner gets it right.

What is the special A/F ratio for an RC51? It still runs on fuel of X specification and X compression ratio................................ Don't get me wrong I think my bike is pretty special but chemistry is chemistry right?

The ideal stoichiometric ratio for a gasoline engine is 14.7:1 but with the crap the EPA and corn lobbyists etc. have added reduces the ratio to 14.1:1.
