Who provides best ecu flashing service

A pound? I took mine off once to change it out and then decided to leave it but it sure didn't feel like a pound of weight....
I was clarifying in response to his excitement that if I remember correctly, then gen 2 pair system is just rubber hosing and likely "closer to 1lb." Not that I'm a human scale and have one hanging off my fulcrum

You bought the plates and did all that work just to leave it?

Just did a quick search since this is definitely already a topic discussed by gen 2 owners. 15.8oz is the weight or the pair system for a gen 2. There are 16 Oz in a pound. 15.8oz might not feel like a pound but it's definitely close.

...I'm a nut like that.....I was in there tinkering and then decided to leave it alone as I kind of liked the pops and bangs once in a while...

I like to get in there and look around and clean sometimes anyways....

Crazy, it sure didn't feel very heavy....but in that case, if someone is looking for each and every ounce of weight savings, this would be an easy thing to do.....
 
The sickos on this site have had me weighing all my aftermarket parts vs stock for years now...
lmao

I wish u could see what was done on an ecu flash. I know mine has been flashed and it runs super smooth, zero hesitation anywhere. but I’ll have to dyno it to know anything. Or find an auto tuner.

For a Gen1 I'de be willing to bet it's just fans on sooner, more timing at lower rpms, and top-speed limiter removed.
Add in secondary throttle plate fueling and opening rate for a Gen2.
It's only in the last couple of years that some shops are adding base tunes for air/fuel for specific full exhaust(based on their shop's dyno-tunes of the same).
Before, air/fuel for an exhaust was rarely added by mail, as most shops, Gen1's eapecially, were still tuning air/fuel through Power Commanders, and Ecu flashes were left to the above mentioned changes.

My bike was dyno tuned through the Bazzaz....

However since getting a flash done via mail, the bike is quite different....it's definitely more aggressive.

It's the timing under 6k and the stp fueling and opening rate on a Gen2, vs just the air/fuel tuned on the dyno.
Just timing on the Gen1, or the timing and stp's on the Gen2 make a big difference alone.
 
From everything I've read about it....all removing it does is stop the pops and bangs....it adds no hp and I've never read about it making anything smoother.

Some just do the marble mod and leave it in place.
I am glad that this topic came up because I have a question to ask.As per my understanding a pair valve is a device which pumps in additional fresh air in the exhaust so that any fuel left unburnt after combustion can be ignited and hence that pops and bangs.Then that exhaust gases passes through the o2 sensor and that reading by the o2 sensor is sent to ECU based upon which the ECU does all the necessary minor changes in air fuel mixture.
If it works like that then the o2 sensor is not sending the ACTUAL reading of what is happening inside the combustion chamber.If an engine is running LEAN or RICH the pair valve will pump in fresh air to the exhaust gases hence changing the ACTUAL parameters and this altered gases will then be sensed by o2 sensor.Now based upon this ALTERED reading whatever changes the ECU makes in A/F mixture the engine will still run LEAN or RICH.
If we block pair valve so that no EXTRA fresh air mixes with the gases coming out directly from the combustion chamber and then these gases pass through o2 sensor will the ECU not get the correct picture of what is happening inside combustion chamber and if it does then will not the ECU make the actual changes that is been needed.In this case chances are that few bikes MAY run smoother or few MAY gain 1-2 BHP but it will be beneficial in some way.
Please clear my doubt because even I want to block the pair valve .Thanks

Depending on who flashes your ECU, the O2 sensor gets shut off......mine was shut off through Moore Mafia's tune....

The only time the air goes into the system is on decel so this doesn't affect your AFR when making power.

The dollar store mod for eliminating the pair is the 'marble mod" which leaves the pair intact....and there have been a lot of bikes with this mod over the years with zero issues.

Other than eliminating the pops and bangs and I suppose saving a little weight there are no power benefits of removing the pair system.

Thank you for the reply.
 
I must say the "canned flash" done by Moore Mafia seems to be spot on, the bike pulls hard at all rpms also idles and runs perfectly.

I sent the ECU there because they do so many Hayabusas that I figure they have them down to a science by now.

The turn around time even for me way up here in the north was quick....

The only thing I can complain about is they didn't include a free Moore Mafia sticker....it would have kind of been nice to get one to stick on my tool box.

As long as you're happy that's what's important to me. I will say the exception doesn't make it true, but it is nice that your bike is running smooth!

Most people send things in blindy when someone has a large following and it appears they do so many, though. I won't say that's a great metric to base someone's quality, I'd look for customer reviews/testimonies of returning/needing remapping.
