Termignoni Exhaust - Justification

[stopintime]

It'll justify the money spent money every time you ride the bike afterwards...trust me .

If you ride your bike 30,000 miles, the price tag for a continous smile on your face is $ 0.05/mile.

WORTH IT

Someone around here correctly stated "Termis sound like God having an orgasm, pets burst into flame, men weep, women's clothes fly off...etc."

A little help here?

That was Spidey who said it, and me that quoted him in my signature. 

One thing to keep in mind about the DP chip though, is that a second hand one could very well be useless to a potential buyer.  You need to check and make sure that any second hand chips had not been "installed" onto someone's bike while using the red key (if you have a bike with red key).  If the red key was used, then the chip has been married to not only the gauge cluster of that bike, but also the code in those keys. 

[sbrguy]

if you like the termi sound, nothing else will do for you.

others like the sound of other exhausts so they get that.  it is all a matter of taste and finances.  simple as that.

do what you are comfortable with and makes you personally happy.

The ECU will still work if not coded with the red key? That would be a bonus if I ever wanted to sell the bike with the stock pipes and sell the Termis separate.

if you want it, and got the $$, then just get it! cause if the $$ aint going to the exhaust, it's gonna go somewhere else. that's just how i look at it.

Right.  You are good to go regarding separating them, or selling the pipes (or chip for that matter) later on as long as the chip is not coded/associated with the bike's red key.  And of course, this only applies to bikes that do have red keys, but the S?R bikes all did I believe.

My S2R SHOULD have a red key but the PO lost it. I got a pretty good deal so I bought it anyway. I was hoping I wouldn't need it for the Termi kit. Sweet!

Can anybody justify spending $1500 for a Carbon Fiber Termignoni exhaust system...i know it includes a new ECU...is that where the majority of the cost is going? Why are they sooooo expensive...Is it the carbon fiber?

Why hell yea! A Termi kit is the best thing since sliced bread? hot and cold running sex? You name it!

And that ECU is worth its' weight in gold, by the way.

why is that? can you get your dyno tuner to custom map the ecu? i thought it was just a single remap,
im not sure how anyone can make a single remap that would be best on EVERYONEs bike, it just doesnt make sense!

seems one of those boxes where you can custom set the AFR at X different throttle positions would be the best thing in the long run


I know i must be wrong, but why?

The kicker in this equation is that you need the DP ecu to be able to run a PCIII or what-have-you.  You cannot use a power commander with the stock ecu.

My bike has the full termi kit and I run it from 400 ft. elev. to 6000 ft. and the bike fuels flawlessly.  I believe it's a little rich if I had the equipment to test it, but the bike is so smooth around town and just hauls arse! 

The ECU is a must have item to satisfy the fueling equation - just pissing against the wind without it.

I haven't done TOO much research, but I understood the exact oposite.  I was under the impression that the wiring supplied with the PCIII was designed to simply bypass the ecu all together so that it could be removed and taken back to stock more easily.  Someone with more knowledge add in here, but what all does the ecu control?  Ignition inhibitor, ignition timing (+/-), air to fuel ratio, O2 sensor, so on.  The PCIII if properly mapped should control all of this with the exception of the inhibitor.  Again, I'm just going on what I remember from my research last year and I don't know how the inhibitor is supposed to remain active, so somone else chime in.

not bypass, just pick up the signal, alter it, and then dump it back to where it was going in the first place. the ecu doesnt even know anything out of the ordinary is happening


most of the afr cards work the same way, and its totally possible (and hopeful) that the DP ecu is more complex


but most of them (or at least the crappy ones) are incredibly simple.

-you wire the box in line with the fuel control, the box picks up the signal, and amplifies it. On my car (with aftermarket induction) its a small box with a dial, and the dial controls the amplification

its simply a variable resistor, anyone in electronics could make one for a few dollars imsure

the more complex ones allow you to designate the ratio (or amplification, or resistance, whatever you wish to call it) at different throttle positions. hence the need for an electronic box, instead of the variable resistor.

if the computer knows how much you are twisting the throttle, and how much fuel its supposed to add
its simply not possible that you cant alter the afr with the stock ecu. unless the ecu bundles multiple signals in a single wire, which afaik is impossible as well. to add a PC or whatever, to an already custom mapped ecu is redundant. or rather, you are paying to have it custom mapped, and then remapping it yourself, so youre double charging your wallet for the same effect

just waiting for someone who knows the inner workings to slap me and tell me how im oversimplifying it, and why

As far as I can tell, you're completely right. The only thing I have to add or change is that sometimes, depending on mods, you do have to remap the bike with a pcIII.

The dp ecu comes already "custom mapped" or the carbon pipes + open airbox / high performance filter.  But if you change any of that (Pods, velocity stacks, different pipes) the map that you have on won't be the best one for your particular system, hence the need for a PCIII and a further custom map.

exactly EM, which is why i think its a total rip to pay for something thats only useful in one configuration!
better to get a pc  and have a dyno guy remap it everytime you change something fundamental about the bike

but of course everyone in the thread is correct, you DO have to do SOMETHING to change the afr once u start messing with airflow
