2-Bros juice Box & Ken's O2 Modifier

[chopster]

On the "other" site Ken has mentioned that the Juice Box hooked up using the factory O2 sensor may not be doing much good. As i understand what Ken is saying, is as long as the factory O2 sensor is kept, the computer will eventually learn and correct the AFR back to 14.5-14.7 regardless of how rich the setting are on the JB. This will defeat what we are trying to do with the JB. If this is how the system is working, the JB that I just installed to assist in adding fuel & tuning was a complete waste of time and money.

I wonder if I should disconnect the factory O2 sensor and reinstall Ken's O2 modifer in line with the JB.

Doe anyone have any thought on this? Hopefully Ken can comment here for us and clear up any discrepancies.

Ken is a sharp guy but he is either not familiar with the TBR JB for the Spyder or :dontknow:

The JB hooks into the stock o2 sensor and modifies the signal. If it didn't it really wouldn't be much good would it?

April fools joke right? :shocked:

I too saw that post as Lamonster sent it to me. :roflblack:

Only problem with their logic was none of these people seemed to remember the Juice Box also intersepts the O2 signal and modfies it as well! :gaah:

Leave the O2 in place, as the program in the Juice Box also knows this and changes the input the computor sees from O2 not just the output to the injectors! :thumbup:

I posted "over there" that its connection into the O2 sensor harness is documented in the Spyder install guide.

Not clear to me if it's part of the JB harness where the JB actually sees the O2 signals or a and alone harness plug-in which woudl be in effect an O2 modifier.

Pete... leave the stock O2 sensor in for the TBR Juice Box. It's part of the program.

I saw the posts too. I don't think it was made clear that the Juice Box plugs into the O2 sensor - at least it wasn't clear to me how it hooks up.

My understanding is that you can basically get more fuel flowing either using something like the Juice Box or the Fuel Pressure mod which requires the race airflow setup.

I think you're two options basically are:

1. Race airflow, Fuel Pressure Mod & o2 mod.
2. Race airflow, Juicebox.

I believe it would be redundant to have both the fuel pressure mod and the Juice Box. Also if you had the o2 mod and the Juicebox.

I like the race aiflow, o2 mod and fuel pressure mod, but at the time they came out the Juice Box wasn't available - if it had been I might have leaned(pun intended) that way. It is nice not to have the big nasty OIL box - but damn is it LOUD with the race airflow! Working on that problem.

Bingo! :thumbup:

What does this O2 modifer does to the spyder and who needs it.

 

[bjt]

It replaces the O2 sensor and I believe it gives a static signal to engine's computer for the purpose of making the fuel mixture richer. Getting rid of the stock "lean running" condition of the engine can improve performance. This is only to be used if you get an aftermarket exhaust. The richer fuel mixture will damage the catalytic converter portion of the stock exhaust.

I have all three and now I have the juicer I see thatI don't need the O2 deleter, but I wasn't aware that I didn't need the fuel pressure modifier as well. Why can't I use both? I understand that the juicer electronically adjusts the pulse rate not the pressure. It adjusts the pulse rate by keeping the injector open longer to give more fuel. If you add more pressure you accomplish that with the same pulse rate, thus not having to go bigger injectors.

Yes put with more pressure you add more fuel everywhere all the time, even where you don't need it.

I changed to the Hindle so I should get one of these and if so where do I get one and how does it get hocked up to the Spyder. What happen when I go in for services, my 600 mile service is coming up in about June at the rate I am riding.

Well since I modified the fuel pressure regulator, I guess that I should drop it back down to teh stock pressure and go with the stock O2(sell the O2 delete) for best results then?

I ran with a Hindle for almost 3,000 miles and never had the O2 modifier. My wife is running with a Hindle and has for probably 9,000 miles and does not have the O2 modifier. Don't feel that you have to get it just because you have a Hindle or any other aftermarket exhaust.

Like tweeder posted, you get them at Evoluzione.net.

As far as what happens if you have this (or any other performance related mod) when you take your Spyder in for service, I guess that depends on your dealer's service department. Maybe you should contact them first to see what they say about doing things like this if its a concern to you.

 

[Just Doo Me]

Does anyone else feel a flat spot or hesitation in first gear? Before getting into second [sm5& Hindle] seems worse after turning from a stop and would the Juicebox address this?

Yeah- since you can't easily reverse the Fuel Pressure mod (would have to buy a new regulator) - you probably won't get much actual help from the Juice Box with your fuel pressure set higher. You'll probably get better MPG by lowering the pressure and using the Juice Box - because as Magic Man said - the fuel pressure mod adds more fuel ALL the time.

For those that have the hindle and notice that slight hesitation - the O2 mod does help that quite a bit. No big deal for service work - my dealer didn't even notice it was changed. It shouldn't cause any warranty problems - it's just sending a fake signal.

Juice box on the way, but from what I gather, it looks like it will do whatever needs to be done with fuel pressure, but will it help with my lean issue I am having? Another words, I must be in the 15.0 - 17.0 AFR because even with the O2 modifier I still gets lots of surging.
If this thing does not affect the AFR, how can I fix that?

What are you running for a pipe ?
What intake mods have you made?
