Lots of back fire

[chinoxl]

Just finish installing keda exhaust, uni foam filter, and breather mod. lots of back fire now. any suggestions on how to get rid of it? and whats the difference with eeprom or race map? will that correct the back fire. i ordered a ecmspy cable and it will be here next week. need some guidance.

thanks,

the race map will help, but you're going to want a custom tune.

After reading the changes you made I would change the thread title to "Lots of after fire" back fire is intake related.

Fuel map adjustments are required to get rid of the exhaust rattle.

what the cost for a custom tune. who or where do i go for a custom tune? in live in SoCal, LA to be specific.
thanks,

You'll need to go somewhere that has a Dyno that you can get time on. Not super cheap but will be worth it.

ok... sorry not backfire. i was told its called "decel popping" any remedies on that buellers?

only remedy is tuning.....or go bak to stock.

if you add more air you need to ad more fuel(i.e. race eeprom)check timing and from what i have read and heard data logging is the way to go because you tune it the way you ride and the programs are free. do you have the race eeprom? if not pm me with your email and which buell your modifying and i will send you copies of the race eproms and stock eeproms. i am about to start data logging myself

Before doing expensive tuning related things such as a custom ECM tune (not saying it's bad though...) try a regular RACE FUELL MAP first.

This costs you nothing and there's always a chance it fixes your problems.

thnaks, dhc. i will talk to azxb12s about trying a race map.

Make sure your header bolts are tight and that there's no air gaps in the system
