Autotune

Has anyone notice Autotune attempts to wrongly tune the fueling. Mine seems to muck up the part throttle above 4000 rpm to the point of an over lean mixture which causes a lag.

At one point it tried to make the fuel cell trim -54 but the AFR reading while riding was 18.

As a result ive turn some of the autotune off.

a good dyno operator will do a much better job vs an auto tune. Ive seen lots of messed up maps from an auto.

Your problem is that you said you are going to tune for 18.0 afr. That's absolutely crazy.

The autotune works perfectly. You are going to have to lower the afr to at least 13.5. It isn't working and has a -53 because you are trying to run way too lean.

And someone sent you a map to use and would be perfect, but you refused to use it.

The leanest my map goes is 14.7 at tickover, then at then moves out to 13 at the richest. I did say i would get the AFR 15-16 on cruse but I would only do that if i had dual maps. One for fun and one long distance/motorways etc when you ride sensibly. The bike with a lean spot in was no good at all but was a good trail.

I know you sent a good map, thanks, which works fine above the 4000 rpm. However, at low revs, below 3500, it made my bike just wanted to go. I've found that with a slightly leaner mixture the bike is more ride-able/controller-able. Your map at lower revs seemed too rich ( whole map 12.5-13.2 AFR buy my gauge) but quick.

My auto tune weakened the mixture where the AFR cells were around the 13.9-13.3 area at 6-7000 on part throttle. I just wondered if anyone else had that issues and a possible cause. Is it due to not enough gas flow. The AFR gauge seemed to be showing the correct reading as to what was happening but the auto tune trim map still wanted to weaken the mixtures.

I did try the figures from your map to try to sort out the issue but the bike still wanted it richer.

All trail and error i know.

Bullstarz, you've got stock headers on your bike and I think jpowell has aftermarket headers. If that's the case, of course his AT map wont work on your bike

I am a bit confused. You say my map worked very good for you and at lower rpms just wanted to "go". Not sure what that means, but in short, these bikes CRAVE fuel.

They were built to run on the rich side as they are 12.2 to 1 compression. The bike will never run right in the afr range you want.

.
When i mean "go", it was hard to keep it slow. On slow corners it lacked control, it either wanted to stall/slow or take off. I found a less rich mixture has allowed the bike to get that sweet spot where it didnt change speed.

Well actually, the maps are all over the place on the bottom end. Sometimes at say 2000 rpm it will subtract fuel and then at 2200 it will add fuel. Overall at lower rpm it removes fuel. Midrange it adds a lot. Top end is good at 0

To the crave fuel statement. I had to take a ton of fuel out of my bike when I put the muzzy ti pipe on it. It was way rich at 1800 to about 2600. I had to add fuel at around 2900 to 3200 and from there on up it was rich.

As I said above, they are terribly rich from the factory at the low end, lean in the midrange, and almost perfect at the top.

If you are using Autotune, the ONLY thing you should edit is the AFR tables and leave the adjustments to the Autotune. Never, ever, ever adjust or add AFR settings to the 0 throttle column. It will load up like crazy.

And contrary what you read, the Autotune will make adjustments if you ride 2 miles down the road and back. It is very quick.

these bikes like 13.2 to 13.5 across the range of rpm...the trim values you see are not gospel especially if theres a huge hike in cell but not in others you ignore it as it effects the cells around it ..
ps sharing maps ..every bike fuels differently due so many variables ...the point of auto tune is the ability to hit target afr for power/economy.but you have to feel the effects of by seat of your butt,or when your trims have hardly changed .ps set auto tune to say start tuning after ten mins of riding .so engines up to temperature .
