Secondary Air Injection Removal

Want to do this, but do love the poppin & banging on over-run !!!!

 

Now you just need some 'saucy pipes'

 

Hi Steve,
Have you had to do a re-map ?
My Bonnie is a 2012 and I am dying to remove the SAI but I have heard varying opinions post removal.
Bike runs perfect and does 'pop' on deceleration but nothing that really annoys me, I just don't want to risk losing any performance.

 

Hi Mick, there are two ways of doing the AI removal in terms of the electrical side. You can do what Steve did, buy an emulator plug that sends a message to the ECU that "all is well"; or you can use TuneECU to turn off the AI within the std. map. So not really re-mapping as such, just a tiny modification.

Both of these options are only there to ensure there are no EML lights - once the solenoid has been disconnected and the plumbing removed the AI system is no longer in place to operate.

If you need more info about Bonneville AI removal, just ask OK?

 

Another option is to remove everything except the electrical pump you can leave this in place still connected
It's what I've done after watching delboys garage on YouTube

 

You're right of course DG, but it means that the solenoid (not actually a pump, more of a valve) is still opening and shutting, so you get a clicking sound, especially on tickover. Not a big deal, but irritating for some pernickety gits, like me

 

I may be over thinking about this mod because I don't fully understand the ECU.
I looked at the removal kit from Greece which has the emulator included and my thoughts were what happens if something went wrong with that little electrical gizmo ?
Thinking that Greece is not particularly well known for its electronic prowess ?
Delboy leaves part of the SAI on to fool the ECU
Forchetto on Triumph Rat solders in a resistor (much the same result as the Greek kit)
If I just wanted to remove the SAI and left the silencers and everything else as standard, would I need to re-map?
3 Options:
1) Remove and fit the Greek kit
2) Remove as Delboy leaving the pump in situ.
3) Remove and solder in a resistor

 

Can't hear clicking on my bike because I have cocktail shakers and can't hear myself think

 

4th option is the way to go , remove all and use tuneecu to switch the sai sensor off in the ecu. This is the cheapest option No costs, I used sump plugs from a Subaru to plug up the head where the air injectors sat.

Mick find someone local who has tuneecu to do the map switching off sai option, I'd do it for you for free ... But shipping your Bike to Perth WA might be the limiting factor ?

 

I've removed the AI, and have a K&N filter and Tec Tracker exhaust, baffle in. I haven't had it remapped yet, but it runs very well, and seems a bit smoother and more responsive. I did the Delboy removal and left the solenoid. I might get it remapped but can't make my mind up if I want to chop the baffle about a bit. Sounds nice with the baffle, but probably too loud for 6:30am starts with it out. I've done a few plug checks and it looks fine.

 

WHAT D'YA SAY ?

 

Hi Capt
When you say remove all, does that include the Lambda sensors or just the SAI ?
Is the TuneEcu reasonably easy to use ?

 

The Lambda sensors are completely separate from the AI System.

 

If you remove the sensors you will have to remap due to different fueling. It's easy to do on Tuneecu, if you can nav the forum it's no harder, nice easy dashboard to use. Also you can check the throttle body balance, mine was unbalanced from the factory which meant a small vibration at medium revs!

Get rid of the snorkel and baffle in the air box and fit a bell mouth intake with a free flow air filter and the combo is adding BHP as well as better running.

 

Hi Mick, I removed the following :- snorkel,std air filter for K&N, baffle in air box,opened top and bottom of air box, ported cylinder head, big bore kit, oxygen sensors in exhaust headers, all AIS (hoses,valve body) did dyno tune and adjust fuel tables and switched off sensors using tuneecu. Bike runs fine, making in the region of 75/80hp.

 

I took my ai out on my thruxton and still get a slight Burbley popping on deceleration
