Fuel mileage effects from ECU flash, Airbox modification, PCV with Autotune?

[mister704]

Hello all,

I have a few questions regarding the fueling effects after installing a MWR power up air filter kit,  power commander with autotune and ecu flash.

I have 2012 1100 Evo, which I know some already have stated the tank is small and mileage is about 100 miles before the gas light comes on. 

How is the mileage affected after doing the performance updates? I was already getting the ecu flashed because of the lean popping but I have the ability to get a power commander with auto tune for a really good price.

I am still in the break-in period on the bike (780 miles) so I can't really install the items yet but I want to know the affects on the fuel mileage after these upgrades.

If you have ecu flash, air box modification and power commander or just some good information,  I'm all ears.

All help is appreciated.

Alot depends on the mapping parameters.
My Hyper has a PCV and optimisers. Others run a reflash and dont need the optimisers with their PCV.
Your mapping is everything. Some use the autotune option you are considering which appears to work well from most reports.
My Hyper is tuned for economy at 25% and less throttle and 4000 and under rpm, but for maximum power above those settings. The AFR ratio ranges from about 13.6-13.8 for economy and smooth cruising down to a rich 12.5 at WOT and peak rpm for max power.
So cranking the throttle makes economy plummet, but my Hypers little 12.5 litre tank can provide about 125 range if Im easy hwy cruising. Having that "dual layered" map of above and below your hwy cruising speeds is quite useful.

I have noticed that tuned bikes often improve fuel economy when cruising due to more torque at those speeds while being able to empty the tank quickly when asking for power.
Much of this depends on how skilled the tuner is and how much time and effort has been put into the mapping. A good baseline for AFR parameters is a good start. I have not played with the Autotune devices but others here have who can better advise you. There is detailed discussion in the Official Closed Loop ECU Mods thread.

125 on a hyper?

125 on a hyper? 

Perhaps that's kilometers? 

[koko64]

Thats 200kms per tank, but you have to remember how careful and law abiding one has to be on Victorian highways . That economy is usually when I'm grand touring with the GLW , so I'm extra careful safety wise. That is short shifting, riding the torque curve, etc. Hard canyon riding may bring it down to 90 to 100 miles a tank.

Perhaps that's kilometers? 

I'm sure under the right conditions...

I have an MWR power up kit with an autotune as well. Depends on fueling but if you keep the cruise range at a slightly higher AFR you'll keep around the same range.

When I'm literally riding it like its stolen (trackdays and extreme hooligan runs in the mountains) I get 90 before the light comes on

If i'm putting around the city, I get around 115. And mixed (but aggressive) use around 100 miles before the light comes on.

I generally don't go below 13.0 on my AFR tables and 13.2 down low. Use the "K.I.S.S" autotune table posted in the forum and you'll be around what's noted above.

Sounds good. Did you find a significant performance improvement?

This may sound weird but I have no idea.

I bought my 1100 EVO in November 2014 for a smoking deal from a 3rd party. One of the caveats was that it had 7450 miles on it. By the time I rode it home the maintenance "wrench" was already on.

I took the savings and put it straight into the bike. I literally rode it home, stripped the bike completely down to do all the work on it at once.

Exhaust, ecu flash, mwr power up kit, ohlins shock, new springs, power commander V, autotune unit, turn signals, valves, belts, exhaust servo motor, etc.

So I dont really know the difference in performance. What I can tell you is that I'm going thru my valves in the next month and I will be removing the MWR kit completely. I have a replacement airbox that I intend to install that will get rid of the mod.

It runs great at high RPMs but even with the autotune and a motowheels ecu flash, the bike doesnt run as smooth as I would have hoped on the low rpm end. I think the bike just sucks in a lot of air off throttle and leans out in unexpected ways.

When you install the MWR Kit, you literaly cut out some resonance chambers on the airbox. There's probably a darn good reason for having them that is beyond my knowledge.

Worst case scenario, is if I am dissappointed with the lack of the MWR kit, I will just cut the new airbox again and install it.

Good info. I am not even going with the PCV anymore as I discussed with Motowheels exactly what I wanted and the gentle said they have all necessary to complete just through the rexxer flash. So I am hoping that is all I need.

 My 09' 1100S with 14T front sprocket ran perfectly with Honda like smoothness. I added a full termignoni exhaust with the baffles out, and it ran like crap!

 I added a power commander with a custom Dyno tuned map and now the bikes is once again a beast. The fuel mileage went from 125-135 miles per tank to about 100 miles per tank now. Most of the improvement was in the 3000-6000rpm range, extra fuel added made the bike smooth at low speeds and it starts much easier now.

Then don't run the mwr kit. And guess who did my flash.. Motowheels. I drove down there myself and got it done in person.

Ah man please don't tell me this. I really hoped that the ecu flash would work. After reading and talking with them, it sounded like theyou do a custom mapping. They said they get new maps in often and have the ability to tune it a lot better now.

Arrgghhhh....I was planning on selling this power commander.

Did you run a PCV Optimizer for down low or a reflash?

 Yes, the newer kits come with the o2 optimizer in the box.

Here in California the EPA laws became much stricter in 2013. It is difficult to find anyone who will build a map on any bike except an obvious track only bike now.

 I'm currently installing a full termignoni exhaust on my 1198. I had to order it out of state. I had to send the original ecm to the dealer for them to re flash with the full termignoni system map. The salesman states that the map will be like a custom map, straight from termignoni and unaltered by Ducati in any way! I'll find out in a day or so when I finish the install and have the tips reset.
