ITG filter install, education needed

Just got my ITG filter installed (and remapped to the 20310.hex, thanks to TuneECU and you guys!) - definitely sounds a bit more aggressive, which is awesome. Haven't taken her out yet, plan to do the 12 minute tune first to see the best gains immediately.

Quick question, and I apologize for not doing as much research as I maybe should have, but I'm getting a little bit of backfire after revving hard and backing off the throttle. It doesn't happen often enough to be a huge concern (or so I believe). Is this normal for Birds, or special to 1700s, or Birds with TORs? It was a little more pronounced with the filter, so I don't think that's the issue. Anyway, just asking the powers that be, wanted to double check and make sure everything is running as it should.

Thanks in advance, gents. It's always a pleasure being here.

I have been at 1600, then 1600 and tors and filter, then 1600/tors and filter and air duct removed, then all of those scenarios as a 1700, then with a custom map, etc etc etc. it goes on and on. What i found is that popping seems to happen more with some setups than others, and even changes depending on the adaption amd weather, etc. In other words, mine has popped badly to almost not at all and everything in between. Sometimes changing with bothing having been touched. So yes, it's normal on this bike. As stock you think it doesn't, but it does. It's just that the stock pipes make the popping so low you can't barely hear it, and when you do it sounds like something other than popping.

In short, you will always have it to some degree. after the 12 minute tune you may or may not have less, maybe even more. i've learned that popping is always going to be there to some degree with this bike. Mine recently was popping less than normal after switching back to 20310 from a custom map, but then after 12 minute tune it popped more. so i reset the adaption so it should be like it was when it was popping less, yet there was no change. No rhyme or reason.....just gotta live with it at times, and at other times not. thats the nature of the Tbird.

Oh, it doesn't bother me at all, I don't mind it, I'm just making sure I'm not hurting the damn thing.

As usual, Daz, you're a well of knowledge, thanks.

No, it won't hurt it at all. It's not only normal from my knowledge, but triumph themselves acknowledged it in an article by citing how it pops and trying to make it sound like thats a cool thing. I guess they were just trying to make people think it's cool before they started complaining about it. It's 100% normal tho. You CAN get it to pop less at times like i said depending on the state of tune, but it's hard to keep it there since the bike is always adapting, not to mention being messed with by us tinkerers who can't seem to leave well enough alone.

Hey guys. My check engine light came on while I was test riding it, came back, hooked it up, and got -

p0413 - secondary air injection short circuit to ground or open circuit.

Not sure what I could have done wrong. Thoughts?

1st thing to do is erase the error code and see if it stays off. If not, what was the last thing you did? If it was to load the map, redo that. If it was the 12 minute tune, redo that. It may have just been a glitch. Sounds like a glitch that should go away with erasing the code tho. Did you do anything physical to it.

Also, come to think of it, since the plug for the tuneecu cable is under the side cover where the SAI solenoid also is, check the plug to the solenoid. You may well have knocked that off and that would certainly throw that very code. In fact, check this first.....seems like the likely reason since you were in there

When the ignition is on and the engine isn't going, it refreshes the error code. When I start it up, it disappears for a minute or two then shows up again. Checked all my wiring, nothing seems to be out of order, even though I'm not sure which wire it is. They all seem in place.

Erasing the error code, redownloading the map, and then re-12ing it.

The error code will not go off until you either erase it with tuneecu, or you go thru X number of startup/ride cycles. that usually means a few days of riding. Just turning on the ignition shouldn't do anything. the light is normally on when the engine is not running.

i would erase it with tuneecu and see if it goes back on or not. If so, then redownload the map which will also reset the adaption, tho i would also do a adaption rest in tune ecu after the map. They say loading a map should reset it, but there are things i have read that suggest this may not happen. So i would do this..

1-erase code with tuneecu then see if it comes back. If it does.....

2-load map and reset adaption in tuneecu. If still no joy....

3-12MT

if after that and you are sure the plug on the solenoid isn't knocked off, the only other thing i can think of is to unplug it then plug it back in. If the contacts in the plug are contaminated that should at least temporarily fix it. then erase the error code again and see if it stays off. If it does i would get some contact cleaner and shoot some in the plug so it doesn't happen again.

this is seriously starting to piss me off.
putting off the 12 because it's hot out and i don't feel like sitting through 20some minutes of heat, but anyway -

resetting the adaption doesn't work. moved the ecu back to 20363 and got a clean diag. i'm not sure which wire it is precisely, but, like i said, i checked all of them in that compartment.

grrr. on 20363 it says i don't have SAI, which makes sense. is there something that i'm somehow missing here - 2011 storm with TORs short silencers and ITG filter. going to keep fiddling with it.
