TMAX map for my 116" have a look
« on: February 20, 2019, 12:53:01 PM »
Hi my setup is a 116" 11.3 comp fatboy ,  been using this map for about a year would like some opinions, I have made changes to AFR and timing quite a few , 

116"
11.3 comp
zippers billet heads 2.0 int , 1.63ex
boarzilla from a dyna , quite baffle
TW9BG cams running at +2
53mm HPI intake

bike runs fine just would like some opinions on areas I have done wrong or would be better , I have no pinging issues , but it is pretty fat AFR,  the timing was taken from base but modified based on some other high comp, maps , mostley in the low and mid rpm areas , added timing ,

It seems like a build like that would like a larger throttle body.

That's just going by what I see.. I'm not a pro and I didn't sleep at a Holiday Inn last night. ;)

I thought that also, but when I sent throttle body to HPI for a blade bearing mod, I was going to go 55mm they said that they would stay with the 53mm ,  something about velocity ,  I did get 132hp 140tq when I had the TW8G cams awhile ago

Can you record data while riding? That would tell you what AFR you are asking for, at which RPM. You may find you are only at 10% throttle at 60 MPH, flat & level as you wave at the guy shooting radar :). No need to have a rich AFR there. I like to cruise ~13.8:1, power between 12.8-13.2:1, and decel just rich enough to not pop.
