How do you dyno a harley?

[shift_red]

Ok the story goes, one guy came to my dyno with a weird request, he wanted his bike to back fire more through a dyno tuning?!!!
i told him it can harm your motor, it is not efficient, you will lose power, etc. but he was adamant he wanted more back fire.
It is a 2008 softail fuel injected, with screaming eagle pipes and some kind of a aftermarket breather.
I told him to run the pipes open but he didn't wanted that, just more backfire
So i started flashing his ecu with the supertuner software, adding fuel every where, advancing timing, retarding timing but with no noticeable improvement............does anyone knows how to get it to backfire more?

i know it is a funny request but hey the customer want it

make it lean on decel and it will usually backfire.

[sportbikeryder]

All at zero throttle openings and high rpm.

BTW, tell the dude he is an A$$HAT!

ok so in the software i can control the fueling using VE for each cylinder, and also i have acceleration enrichment and deceleration enleanmet..........so basically i need to take out fuel from the deceleration enleanment feature?

DON'T DO IT SEND HIM AWAY.All Money not good money...if he gets hurt it won't be him suing you his family will.

[shift_red]

you are right............what confuses me that the guy is in hid mid 40's and he is an executive manger in a company. anyways i have tried and failed so i guess that is a good thing in a way

[GreenMachine]

what a dumbass-i have customers pay me good money to get rid of that fuggin' decel pop, and this douche wants to pay for a backfire. WOW-they should immediately revoke his license

HAHA an a$$hat.. but we get harley an cruiser guys asking that alot suprisingly but there paying 150-200 for a tune so they get what they want .. we jus drop fuel at 0 throttle but we always tell them that is not good on the bike, and that we dont like to do it but like you said what an as$hat

[ratt2y]

well, you could drill a 3/16 hole in the back side of the exhaust about 5in. down from port? when he backs off it will backfire,
