Setting-up the PCV-AT for mileage and cooling

You can insert offsets for different gears, e.g. +10 for 3rd gear, but I can't see an application of this for my needs. It would be nice to have the option of specifying where you want the offset, like in the cruise range. As it is you'd be getting +10 across the board, and that wouldn't be useful to me since I already have 60% TP and up configured for performance, so going richer there would be too rich. It you set it leaner in 5th and 6th gears you would run into the same problem of it being leaner than you want at WOT.

OTOH, an offset for head temperature might have some merit, but it too isn't selective, so you couldn't specify it only for the cruise range. You could set it to offset +10 or more for front head temp above, say, 290
 
Iclick, I notice some of your trim values are as high as 30%. Did you change the maximum enrichment & enleanment trim settings to a larger value than the default 20%, or will multiple runs add up trims cumulatively?
 
I-Click, thanks so much for taking the time to do this post.

Your write up is just what I needed today. I just completed installing the Autotune tonight. I started the bike and it is working, the trim values changed, and the AFR readings are varying as I would expect for both cylinders. I am going to run on the rich base map for a couple of days to get it right before accepting trims.
After the rich map is setup, I am going to use the leaner map for everyday.

I have the same question as MI Jim. I too noticed your values on your trim tables up to around 30 in some cells. What are your max settings for trim values?

Thanks again for the great post.
 
I'm now replying to my own reply, sort of like talking to myself.

Anyway, after a ride today I'm seeing one trim cell at -31, so the change made a small difference. I also put some AT target values for 1250 rpms @ 2-10% (same as for 1500 in that range), and my trims look normal, so they'll stay.
 
Is there somewhere in the PCV/Autotune software that verifies the map switch is working while Autotune is enabled? I hooked up a switch temporarily to the bike in the garage. I enabled the switch in the software but no matter what position it was in there was no indication that it was working. Do I have to test ride the bike in both positions and check for trims after each ride to see if it is working or is there a way to check in the garage. I ordered the HD acc. switch housing and switches but they wont be here till next week so I tried with a temporary sw.
Also, has anyone had very high negative trims in the 2% column from about 2000 RPM to 3250. If i accept trims after every other ride or so the trims in that area keep going further negative. The last time I looked it was at -32 and the bike ran like shit at slow speeds. My base map in that area was already at 0. I reinstalled the original base map 2 times and the same thing starts to happen. I called Power Commander and they said to put a 0 in that part of thr AFR map. Ive done that but have not had a chance to ride since then to see what happens.
Anyone else have this happen to them?
 
It is sometimes difficult to determine if the switch is working, and nothing in the software tells you except the reaction of the various gauges like AFR's and Fuel Adj. The problem is that it isn't practical to work the throttle more than about 2-3% while idling in neutral, so if there isn't any or much difference between the open- and closed-loop values you won't see enough change to tell you anything. Since 2% TP @ 1500 rpms is easy to reproduce in neutral, temporarily change your Target AFR to something like 14.8 at that spot. This is assuming your base map is rich enough to show a difference when you switch. If so, connect the bike to the computer and launch the PC software, then run the engine at that TP and RPM. After the O2 sensors warm-up (about 1 min.) and you see AFR's show up in the software, flip the switch and you should see a change in AFR's and Fuel Adj. gauges in the software.

Another way is to put a passenger on the back with the laptop computer and have him or her watch as you (or the passenger) switch back and forth. That way you can access most any RPM and TP within reason.



Yes, I'm getting that, but mostly at 2750 and 3000 rpms. Go back to my original post in this thread and look at my sample trim table, but keep in mind I'm using 14.2 in that range. I'm not seeing it getting leaner and leaner like you are, but I'm not accepting trims anymore since it works against what I'm describing here. I really don't think this RPM/TP area is anything that would affect the bike's operation, as I think you'd run into it only on decel. Where is the weakness felt?

Where I did have a problem was high negative numbers (-25 or greater) at 1250 RPM's @ 2-10% TP and it was causing it to feel weak right off-idle. Here it seemed to get leaner in time, so I changed these values to "0". That tells AT to run only the base map values there, and that fixed the problem. You can see this in the sample Target AFR table in the original post. Since all of these issues occur at low TP, I tend to attribute this to reversion where air backtracks to the O2 sensor and forces erroneous readings.

Be advised that if you do this the trims will still be there and the PCV will still use them. Thus, if it was too lean before it will stay that way after you add the zeros, as the trim values won't go away. You'll have to Clear or Accept Trims, which zeros the trim tables, and then change the Target AFR values to "0" in those locations.
 
My bike seems to surge at about 20 - 30 MPH. while riding through side streets if I keep the high trims that autotune wants. Other than that there is a big differance in the bike. It seems a lot quicker and runs better and better as the autotune tweaks it. I am going to start from scratch with the original map from Fuelmoto and add the map switch, but since Im recovering from minor surgery and the doctor said no riding for a while I have time to mess around in the garage. During my down time I was really thinking of some new cams.
 
Another great, no, phenominal, write up IClick. The entire post has been educational for me and when the new ride and Fuel Moto equipment arrives, one day, I'll be going directly to this post.

Everyday I read these excellent posts regarding the new high tech equipment and I thank God for the 'save' button!
 
Thanks, glad it helped. I was getting quite a few PM's and was repeating myself on related threads, so I felt a write-up was necessary even though I knew it wouldn't draw heavy general interest. This procedure works great for me and I felt the ideas needed to get out in the open and give me a link to refer to in the future.

I hope I get some feedback from others who've done this.
