How many fixed the fueling issue and how?

Hi Folks,
The more I ride the bike, the more I love it.
But I need to fix this 1st and 2nd gear fueling hesitation.
Is the Z-Bomb the solution?
Will it affect the reliability/integrity of the bike at all?
Is it good to use just by itself or does it require a PCV and mapping?
If you buy a PCV and have a custom map made, do you still need a Z-bomb?
The Bazzazz post here suggests to use the Z-Bomb AND something such as a PC. What's the point of having the Z-Bomb if you are controlling the mapping with a PC?
How did you guys go about fixing these issues?
I have limited knowledge in this regards so thanks for helping out!

 

Really? No-one? :-O
I tried to ''search'' the forum but it yields no results other than this one Bazzazz post (which has no replies either, interestingly).

 

Well ..... we have no idea what bike you are talking about.

If it is a new VFR1200, the feedback on the Z-Bomb is that it is awesome and totally fixes the fueling issue. On the down side, the gear shift indicator gets wonky.

If it is any VFR 800, (AFAIK) they make a Z-Bomb for the 6th and 7th gen. Older bikes have to use PCIII for now, but Bazzazz says they are working on something for the 5th gen.

Do a search for posts by Bazzazz. They are on the site.

DOH!!!!!

If it's any help at all, we here in Europe got the new map last year and it fixed whatever fueling issues there were. Especially low-down. So I see no need for a PC V or any other "after-ECU" device. Which, I might add, I don't like. I much prefer something like Tuneboy/Tunedit for Aprilias and Triumphs that goes directly into the ECU. I have about 10 years and dozens of self-made dyno runs of experience with that, developing exhaust systems for Aprilias.

As to the first and 2nd gear restriction: that's just stupid so my Z-Bomb is on its way over. Ordered via a friend in the US as Bazzaz's service here sucks.

I'll have it next week.

 

Yeah! What he said! LOL:wink:

But kidding aside, I can't find anything except what Bazzazz has posted so I would like a non-biaised, educated opinion.

I don't want to do something that will damage the bike in the long run, create problems, or necessitate a lot of $ to make it work properly.

I am also trying to understand why you would bother with the Z-Bomb if you are to install a Power Commander (or equivalent), since the latter allows you to alter the fuel mapping.

Ride safe!

 

Thanks for your feedback Befbever!
So basically you are saying that Honda came up with a ECU reflash in your market but that it did not resolve the first and second gear restriction?
I understand that the Z-bomb simply fools the bike in thinking it is in third gear. How ''efficient'' is it to use the 3rd gear map to run 1st and 2nd gear, is the map usually different for each gear?
When you say that you don't like after ECU devices, why is that? What would be the disadvantage of this, as they seem to allow you to customize your maps?
Sorry for all the questions, I am trying to get more knowledge to understand what I will do to my bike!
Your feedback is highly appreciated!

 

Yes that is exactly right.

I didn't get the e-mail from Honda saying each gear has its own map. It's possible but it would be overkill IMHO.
If there are differences, chances are they're ignition only as the Z-Bomb only fools the ECU into thinking it's in 3rd gear.

Oh dear I really don't want to start a big discussion about this. I just find it more logical that you change the mapping/ignition at the source, meaning the ECU and don't try expanding on what's already there. That's just my logic at work, people do whatever they like. I've ridden an few Aprilias with PC III and a few with direct mapping changes - including mine with ignition changes made by the finest dealer in TX, USA - and every bike with PC III behaved erratic, stuttered, jumpy idle etc. I had no such things. You have to know what you're doing however. Without careful reading of the gas analyzer, plugs, signs on the road etc. this can end in disaster if you're not able to interpret what you're reading and feeling. Let's just say that if you want to do track days, by all means fit a PC V or any other "after-ECU" thingy.

Not a problem. I'm no guru, I just use logic sense.

 

Just as an example: I had a Triumph Tiger before this Honda and after 3 Aprilias and when the mechanics fitted the Arrow race can they also changed the mapping. I had no grip in the wet. The bike just spun everywhere in the first 3 gears (triple engines have torque!). When I finally got my Tuneboy cable from Australia, I discovered that the mechanic had put in the wrong map. There was a specific one for this exhaust. Being curious, I checked what the differences were. Some fueling, not a lot, but quite some significant ignition changes.

I loaded in the proper map, a 3-minute job, and hey presto: the wheel spin was completely gone.

Just sayin':smile:

 

This is only my understanding.

Vfr 1200 are a fly by wire. The pc cann't fix the 1st and 2nd gear restriction issue, cause its controlled via a different process. All the zbomb does is trick the bike into thinkings its in 3rd gear for 1st and 2nd. This
removes the restriction. Its also why the bike displays 3rd gear for 1st and 2nd.

U still need the pc to fix fueling issues if u are running a pipe or u just want to richen it up.

This is only my very basic understanding. I could be wrong

 

You're certainly not wrong. I'll let you know what the z-bomb does when I get it. If it does what it says on the tin, I'm happy. Which doesn't mean my next bike will be a Honda. By no means.

I loved Soiciro but he has long gone.

 

hi i just put the bazazz bomb on my bike and it is like night and day wants to rip its self out of its skin will come up in first now on the throttle and will come up in second with the right road conditions well worth it can wait to get my two bros slip on in a couple of days

 

Can't wait to hear your feedback on the Z-Bomb!

Is it safe to assume that:
* Z-Bomb + Stock exhaust = no need for a PC;
* Z-Bomb + aftermarket exhaust = need a PC

Aside, is the PC the way to go in term of fuel management devices (as opposed to ''equivalent'' products)?

 

Fantastic!

 

Define 'aftermarket exhaust'. If you mean slip-on like my Remus Ti, there's no need for anything else. Like most FI bikes, the ECU gets his parameters from various sensors and it will be able to compensate within its limits. I see no point in a 173-hp bike making 175 with a good slip-on and then wanting another 2 hp with a PC.

With a full system, things are different. The systems we designed worked well with stock setup but the right changes to fuelling and ignition added quite a few horsies on top of that. But such things were only done by die-hards like me.

Dynojet's Power Commander is an authority when it comes to aftermarket tuning. There are others but I have no experience with them. I just think about what my tuning buddy always said when it came to re-jetting road bikes: bike manufacturers these days are no idiots. They'll make a bike that can ride at sea level and altitude. In hot and cold. In rain and dry. Food for thought huh?

I have a 2010 standard VFR1200. I spliced 1st to 5th and 2nd to 6th and fixed the 1st and 2nd gear detune.
Then Leo Vince slip on with PCV two brothers map; runs fantastic. Wish I had TC though like the new VFR1200.

I am using the Bazzaz Z-bomb (Bazzaz.net - Z-Bomb Honda VFR1200F 10-12) with the Akrapovic slip on. The Z-bomb takes all of 3 minutes to install and completely changes the 1-2 gear lower end character of the bike.
