The latest FP 3 software has a setting for decel pop. I get some even after running auto tune. Before I try it has anyone used this individual setting and had success or negative effects ?
do you flash immediately after picking the firecracker?
The decel pop feature was a part of Fp3 since day 1. Depending on how bad ur decel pop is, select the firecracker icon.
Decel pop happens when some of the unburnt fuel from the combustion cycle enters the exhuast manifold which later is ignited by the heat from the header itself causing an audible pop and of course all this on deceleration.
The decel pop feature on any tuner works by compensating more fuel on decel, so that the exhuast header heat will not be able to ignite the unburnt fuel.
The side effect of this is reduced fuel economy..u will be notified about it when click on the info button of the Fp3's decel pop page.
