From the automotive side,The heaters are used to bring the up the 02s to temp quicker and therefore closed loop operation to meet emissions standards can be achieved quicker.Once the exhaust heats up and is able to keep the 02 at operating temps the heaters turn off (in stages on some vehicles)and only come back on if the 02 switching slows down.

Most cars now days have a goal set of about 30 seconds to reach closed loop operation.

I have been turning mine on and off for years now.. just trying to understand...

I know they still work because i turned them back on for a map i have been running and tweaking for several thousand miles and picked up about 4 miles per gallon on my last 3 tanks full... So your statement on fuel range was a proven for me, i was a bit skeptical.
The throttle response seems more sensitive or quicker with them on, but still with this map it is very smooth with no hunting or flat spots.
One thing i did notice was my fan kicking in a bit more and actually going to 5 bars while still moving all be it in 1st gear on a cool day, which it didn't seem to do the 02s off.

I am running the stock map for my bike with changes to the F/L Switch, ignition and 3% more fuel on the F map down low, and no secondary butterflies. My last MPGs check i was at 44.5 with dirt wheel setup and 17 - 45 sprockets.
So if i would put on the street wheels with the 42 tooth and ride tarmac i bet i could see another 2 to 4 MPGs.

I am pretty friggin happy with how this bike runs, so Thanks to the TuneECU guys and everyone who has offered up there knowledge info and findings.
Hey Dusty, is this map posted somewhere? I'd love to check it out. Also, for what year?

The map i made is for my 07... Dual arkaprovic with DB killers in, stock air no pre filter, no secondary flies and full ectomies.
It isn't far from stock, biggest changes are the F/L switch and ignition.

This map was made by seatopants... no dyno... still a work in progress, but the best map I've had on this bike yet.. PM me with an email add. and you can take a look at it, if you load it its at your own risk!

Looking at getting this multi function gauge and wideband hooked up this winter to get a better handle on things, and possibly a data logger later.

Mapping info please

Map question???

Can you use any (year wise) 990 FI map on my 2012?? I see several maps but show different years.

I have a 2012 990 with Sporting Wood airfilter, Leo slip-ons (Dual), SAS removed, Canister removed.

Thanks inmates...,

Smitty

The 2007-2008 bikes have a different head and some other differences so don't use those. Anything 2009 and up will work on your bike.

Hi guys,

I just receveid today my data cable from Powercell.

My situation is that I use my bike as a daily commuter 16 weeks each semester, from february to june and august to november, the rest of the time I want to ride off road.

I need a map with a good fuel consumption feature, Currently she´s is doing 48 km (30 mi) per gallon in highway and 43 km max (27 mi) in city.

When I purchased it, she did 60km (38 mi) per gallon but I had to took to to an authorized service due to a misconfiguration of TPS or stepper motor.

I am getting poor and poor because I ride (1250+ mi) 2000+ km per month and I know she can do more mileage.

Thanks for the help

I've been searching a ton and can't find anything definitive - I'm hoping folks can help fill me in!

So I'm doing a canisterectomy on my 07 990 adv and also have and am very familiar with tuneecu.

I've unchecked SAI and EPC. I've simply unplugged both the SAS pump at the back of the airbox and the evap pump at the front.

I'm seeing a purge valve open circuit error code.

So I'd hoped and it had been suggested in various threads that resistors wouldn't be needed if using tuneecu.

Is anyone actually running w/ canisterectomy and sas removed, no resistors, and no error codes?

Also, the 'SAI' in tuneecu - does this refer to the air injection into the exhaust or to the evap into the intake manifold?

Loaded my first map, along with a bunch other stuff. SAS, canister, air filter, new map.. And like magic.. The beast RUNS!!!

I did turn off the SAS, but also added 2 22K resistors. No FI light on my ride....

No resistors needed fuel injected 990's when you uncheck "SAI" in Tune ECU. Unchecking "SAI" tells the bike's ECU to ignore the SAS pump and canister pump.

The resistor thing is for poeple who don't have Tune ECU and can't tell the ECU to ignore the SAS pump and canister pump.

If you see an error code after unchecking "SAI" then it's something else going on.

I have a 2012 990 Adv R. I have removed both the SAS pump and canister pump. In Tune ECU I unchecked "SAI". I have no FI lights and the bike runs great.

I have not checked for error codes in Tune ECU but even if there is one I'm not seeing or feeling any issues when riding the bike.

You DID clear the codes, right? It's not a real-time system; you've gotta clear the code after you uncheck SAI and load themap.

Yeah I cleared the codes but the purge valve code kept popping up. Then when I plugged the pump back in the code went away.

Hmm so is this an '07-08 FI thing? Sounds like The Griz's 2012 doesn't have any issues once SAI is disabled.

Seems a little fishy - any ideas as to why I would see the code despite having the SAI unchecked in TuneECU? FWIW I have the SAS pump unplugged and no error code there, only the evap seems to give me an issue...

I've just plugged the pump back in (no hoses attached) for now - I could put a resister across it but it sure would be nice to fix in TuneECU for sure

I already had the 22K resistors made up, and was not planning on remapping. After deciding on a airfilter change and other mods, I was to the point where a mapping change was a must. I just left them in place, but have un-check SAI in TuneEcu.

Ok, staying with the obvious here and no slight intended.

Did you reload the map after unchecking SAI? Gotta do that...

I had a similar issue on my 2007. For some reason checking off sai in tune ecu would only allow the system to ignore the sas purge valve and not the evap canister purge valve. I ended up putting the resistor in the canister valve and all is well. I'm not sure if it's a 2007-2008 thing or not, but I know the electronics for the injection system are different between these years.
