What will adding one firecracker in the FP3 for popping do to fuel mileage if any? Anyone try this option yet?
I installed the 1 firecracker on my flash and my decel pop is 100% gone. I don't know what going to the "higher" decel pop icon will get you with regard to fuel, timing etc.
Was that advice not to ensure that the fuel pressure (a very important variable in the EFI equations) was up to where it should be?? Long time since I've read it but was that not in the owners manual?
Yes Gordon, the "wait" does allow the fuel pump to build adequate fuel pressure, it's good policy to do this. I am not an EFI guru, but do understand the ECM has to process info prior to start up, at start up and when running. It's a good policy to give it a few seconds to do this.
The FP3 is the second tuner I had this summer. The first one wasn't working out so I traded it in on the FP3. I don't have V&H pipes so I chose the generic slip-ons and ran autotune for a couple days and finished it. It was running OK but I was still getting decal pop and I wasn't real happy with how it was running.
Then I put it in autotune mode again and ran for a short time and applied but didn't finish. Then it started running real goofy. Running real rough, also the throttle was very touchy. Took it out of autotune and Flashed back to previous finished autotune. Then a week later thought I would try again. Same thing so I shut it off and called V&H support. They told me not to use Autotune. The Autotune can tune your bike to lean or to rich. I said I thought the Autotune feature was the best part of this tuner and he said no it was not. Told him I had Fuel Moto Jackpot Classic Slip-ons and he told me to choose the V&H Twin Slash Round Slip-ons and just leave it. That should be spot on and not need any changes.
Now it's running great. Decel pop is not completely eliminated but it pops less than it ever has with the new slip-ons. I've been messing around tuning this thing all summer and if I knew it was going to be this much trouble I would have left it stock. If what the V&H tech told me is correct the marketing for the FP3 is misleading as far as the Autotune feature is concerned. If I was to do it all over again I would purchase V&H slip-ons and the FP3 and forget about Autotune.
Probably best to combine the auto tune with a dinomometer by a tech.
The results I got after about a combined four hour auto tune was nothing compared to the canned map V&H sent me.
Still using the very first canned map they sent me from day one.
Bike runs so awesome, I see no point in trying the other six available.
Will probably never bother with the auto tune ever again.

Go into the tune your running and add one firecracker and that should take care of your decal pop.
I keep hearing about this "firecracker" thingy. ??
One of several selections to modify the canned map is a selection of 1-4 firecrackers to "taylor" out the decel pop. I selected 1 firecracker before I downloaded canned map. It eliminated my decel pop 99%. Another selection allows you to adjust TBW response(feel) and now a selection for cams.
The canned map I loaded is almost perfect, but I will play with the auto tune when weather cools down. I think it can improve it even closer. If it does not I will reload canned map back in.
The firecrackers thingy throws extra fuel into the higher rpm in the 0% throttle column. Have a look at the 2014 maps ...there seems to be a ridiculous amount in there already
