So the previous owner of my '05 S3 did a partial SAI delete - it is no longer functional, but the solenoid valve is still floating around under the seat. I figured I'd just unplug and remove it, which of course caused a Service Engine light immediately upon startup. I don't like that, so I grudgingly put it back in under the seat, but can one of you guys tell me the solution?

Do I just need to jumper the solenoid lead to defeat the circuitry, or is there an ECU reset that needs to be done?

To remove the solenoid and NOT get a CEL (check engine light), you need a non-SAI tune in the ECU.

I think I remember someone using a jumper circuit and having problems.

I had the dealer put the TORS tune in last week - would that not do the trick?
kartstar, the TORS tune here would be SAI equipped. Don't know if you can ask for an Aussie tune or not, but I believe if you can get your dealer to load the Aussie TORS tune, it would be non-SAI equipped. I know very little if anything, so don't take my word fer it. :violent1: ;D

You will need Tuneboy or a AUS or UK TORS tune if you want to remove the SAI solenoid.

Or you could simply leave it in place - ziptied out of the way.

The bike runs fine, and definitely stronger mid- and upper-range. He test-rode it after the retune, as well. My dealer here in Asheville really seems to have their stuff together - I trust them so far.

Devi - I'm just a little anal. I want that sucker gone! And think of the few grams I can drop...

I will call and ask him if he's got access to the TORS tune without SAI. Otherwise, I guess I'll start looking for a TuneBoy I can rent for a few beers...any takers? Beautiful Asheville NC...local knowledge of some sweet cop-free backroads...74 degrees tomorrow...

kartstar, if you can git yer hands on a tuneboy, that's what you want to do. I could tell a very nice difference in the midrange after I loaded a tune. ;) ;D I would be more than happy to help ya out since I'm so close, but I borrowed one myself. ;) ;D

The basic 20088 dyno tune will make more difference than the silencers and TORS tune.

If you can swing buying a cable or borrowing one and getting a key, I highly recommend it. The midrange will come alive. And it allows for further performance mods.

I would send you my cable to borrow, but I am hoping to need it soon - when I get the engine back together.

I've got a TuneBoy and am only about 50 miles south of Asheville. I have one of Devi's tunes loaded and am loving it. However, you will have to buy a TuneBoy key for your ECU. Each ECU has a serial number and TuneBoy needs a key to make any tune mods. Check out the TuneBoy site, IIRC an additional key is $199 AU. We would have to hook you up twice. Once to get your ECU serial number and email it to TuneBoy and a second time after they email the key to actually load a map. They typically send the key within 24 hours which is pretty good considering the time difference.

APtech77,
Yes, it works with the newer ECUs, but I do not know if the better tunes that have been developed on the dyno will work for the later ECU. There seem to be some differences.

You can replace the solenoid with a resistor if you want to get rid of it. It works okay on mine. As I recall, it's 20-25 ohms. There's some threads either here or on triumphrat. I used jumbo sized (5 watts or bigger) Radio Shack ones.

Funny- I just got off the phone with the service mgr at Myers Ducati/Triumph in Asheville. He says he has a non-SAI tune he can load, and will do it for me when I take it in for the 6000 mile service. He's also willing to piecemeal the service ie I'll do the oil/filter change, check plugs, etc while he'll just charge me to balance throttles/check for DTC's - stuff I can't do. Oh- and he VOLUNTEERED to do the brake piston warranty work while it's in...

The more I work with this dealer, the better I like them!

dr_gallup, I appreciate the offer, and I may in the future take you up - I just can't drop the $2C right now. I have a kart race in April and a moto track day in May I'll need tires for!

Good to hear that Meyers is taking care of you. I've been wondering about them since they are the second closest dealer to me. The local shop is a useless as t!ts on a bull. I'll have to stop by Meyers some time & check them out.

Don't use resistors to bypass the solenoid. Its more trouble than its worth and its a lot cleaner and will make you happier in the head if you just get a non-SAI tune downloaded.

Just curious, how did they go about their 'partial' SAI removal? Did they use block-off plates or just tape off the airbox?

Don't have a real good answer for that - pulling the tank off for the first time in my ownership tomorrow...I'll probably make some block-off plates, because I doubt it's been done properly. Old owner seemed more interested in aesthetics than proper mechanical operation!
