I should be picking up a full leo vince system within the next week but need help with what fuel management system to get.

I'm not that experienced with tuning and this is my first bike so what would you guys recommend. I have basic mechanic skills but I read the bazzaz install is a bit in depth compared to the Pc3.

thanks guys

i like the bazzaz, but then again i've upgraded mine once now (from the regular zfi to the zfi-qs) and also have the afm (auto tune). i LOVE it - and buddies of mine that have gone from a dynotuned pc3 to a bazzaz and afm say it's like stepping up to a built motor. not sure if it's 100% true, but i do know that my bike would pull both the dynotuned pc3 bike, AND the "shelf mapped" pc3 bike, AND the stock bike (all 06/07 R6 bikes).

the price for just the box is about the same - but the pc3 is dying technology. the pc5 is the next step up, and that's more flexible in terms of tuning and expansion like the bazzaz is.

hopefully this didn't confuse you too much.

there's a how-to on the bazzaz install on here that i did - i can do an entire system now in about an hour (took me 2 days for my first one). :nono

With what your saying I would recommend the pcv. It will be easier to install and yo ucan get it with a basic map already loaded on it. Us (or any dynojet dealer) can upload a map on it so you can just install it and go. You could also get a custom dyno tune if you wanted or even install the auto tune, sfm, etc and tune it yourself, control 8 injectors, etc. That's down the road though if you want to learn how to do your own tuning. If you really want to do your own tuning then I do like the Bazzaz, but if you don't think you'll want to do your own tuning then get the pcv. It has a huge map database, more dyno tuning centers know the unit, and you can upgrade it to do nearly everything later on down the road if you want to.

Custom tuning yourself is great, but you really need to be mechanically inclined or willing to learn a lot to do it properly or you risk damaging your engine.

I'm one of these guys. While maybe not quite a "built motor," it does feel like I gained about 10 extra hp. You can set you A/F ratio to whatever you'd like and adjust the percentages from there as well. I don't know much about the PCV but I'd give the advantage to Bazzaz. Hey, the big boys in the AMA run Bazzaz so it can't be all that bad:lmao

Thanks for the help guys. I've been looking at a zfi and afm for a pretty sick price, basically the same price as a used pc3. I was just worried that without prior tuning experience I would mess things up and the bike would never run smooth again lol.

I'm leaning towards the bazzaz even more now after your guys input.

If you go the Bazzaz route don't be afraid to ask questions. There are plenty of threads on it with lots of great information on them.

The zfi and zafm are way over the price of a pc3. The pc3 is cheaper then just the zfi and then you still need the zafm. You can mess things up with the bazzaz zafm or the dynojet auto tune and wreck your engine if done incorrectly. If you're going to self tune it do your research prior to purchasing and getting into it. If you're not the diy type of guy or mechanically inclined these are the last things you want to touch. That's not saying you can't or shouldn't, but be willing to research and learn and become a diy type of guy if you get one of the self tuning fuel controllers.

Bazzaz use to have 8 injectors over the pcv, but a while back dynojet released their sfm which controls 8 injectors and lets you add a quickshifter. Not that you can't run a qs4 or hm quickshifter with the bazzaz zfi.

zfi:
controlls 8 injectors right out of the box
you set the afr then you have to apply the changes
gear dependent fuel trims
can store two maps and change them with a switch.
multiple afr's
smoothing feature
You can upgrade and go with the zfi-qs (quickshifter) or TC (traction control) units. The bazzaz quickshifter is one of the smoothest i've used, but it sounds like the op is just interested in the fuel controllers.


pcv:
controlls 4 injectors out of the box
you can buy the sfm to control 8
you set the afr and it auto changes the map for you or you can set it to manually do it like the bazzaz.
multiple afr's
smallest device out there
powered by the usb cord so you can map it off the bike w/o a battery
can store two maps and change them with a switch
you can add on a quickshifter via sfm
you can map each cyl individually.
Gear input (allows for map adjustment based on gear and speed)
map database

With the pcv and the bazzaz it's best to take off the zafm/auto tune once you have a solid map built so you don't wear out the wideband sensor or tune to a bad sensor as they do have a lifespan. The biggest problem is because the pcv is a true closed loop system if the sensor goes you'll be tuning to a bad sensor so it's best to take it off. With the bazzaz since you have to apply the changes you hope you'll notice a failing sensor (if you know what to look for). With either though you can avoid this by taking it off once you have a good map and just retuning when you change mods, etc.

With that said I use the zfi-tc, but if the sfm was out when I needed the fuel controller I would have gone with the pcv and ran a wideband off every cyl on my headers to get the best tune out there for each cyl. But back then dynojet didn't have their addons available which made the bazzaz a no brainer for me.

Amarr has some great stuff in the works right now though :) :fact

So you're saying once I get a good tune after applying all of the % changes (multiple times) I need to disconnect the afm???

i would. The widebands have a lifespan and the worst part is they rarely just die. Normally they start giving false readings and you'll be tuning to that in time. Best to take it off and cap the wideband bung and not use it again until your mods change or the temp changes drastically. I have a summer map and a winter map. I won't need to retune now unless i change my mods. There is no point in keeping it in there making changes that are like 1-5% changes. Once you're in that area just take it out.

Good info Corey, I'm going to make a few maps for different temps and then go that route once I'm happy with the tunes. We need a mod to get this thread and some of the others stickied.
