I installed a PCV with Autotune on my 07 Ultra and started the tuning with a map provided by ICLICK and the Autotuner seems to be tuning way out of spec.

My bike now spits and spudders and backfires between 2000 and 3000 rpm. I will take screen shots of my current tables (when I get home tonight from work) after accepting the autotune settings a couple of times. Many of the values were maxed out (20%) each time I accepted the autotune settings. The values are now very very high for cylinder 1 and very negative for cylinder 2.

My 07 Ultra has Rinehart True Duals with Big City Thunder baffles and a SE A/C. Everything else is stock on the engine.

I started tuning with a base map provided by ICLICK:

PCV-1a.pvm: This is Fuel Moto's original map for stock cams and Jackpot
mufflers.

The following are screen shots of the base settings before I started tuning:

Cylinder 2 Table


HELP!!! What am I doing wrong? OR What could be wrong with my bike?

The map that I started with ran much better than what I have now. Why does the auto-tune seem to be de-tuning my bike?

Any help would be appreciated.

Thanks,

Scott

 

I'm sure iclick will be along shortly with some advice.
I have an 07 Ultra stage 1 using a PC111. My settings in the 0 to 20% throttle range up to 3000rpm are about 1/3 of yours. I'm thinking of lowering them further.
I had my bike dynoed be a very competent tuner and my numbers in those ranges were roughly half what you show. I decided to drop them for even better mileage and it runs fine.

 

my opinion is let the Auto Tune do its work. Set your target afr's and run, than accept trims.... then re-run and keep doing this for a while. Since the pop is only within 2000 and 3000 .... I would keep the recommended 20% settings (how much the PCV can adjust your afr)
After a while, you can change the 20% to say if wanted. FYI--- I think HD now has its new bikes able to adjust 25% on the fly.....

 

We'll need to see either the Trim tables before accepting trims or the Fuel Adj. tables afterward. Whatever is going on you should not be having any stumbling between 2000-3000 rpms, and although it is typical for trim values to be different between Cyl. 1 and 2, they shouldn't be radically so.

Before you accept trims, be sure that you save the original map to a unique filename so it won't be lost. I'll look forward to your screen shots tonight after you've accepted trims, as that might give us a clue what's going on.

When you connect the computer to the PCV and let AFR's settle after running the engine for a minute or so, are you seeing normal values? I would expect to see something in the 13-14 range while idling with this map. Vary the throttle up to 2000 rpms and take note of the AFR values shown, which also should be in this range for both cylinders. Report this info when you post later on tonight. Keep in mind that it'll be hard to emulate actual riding behavior by revving in neutral, as you'll likely not get higher than 2-3% TP this way. I just want to know if you're seeing normal AFR values while connected to the computer.

 

My money says its the True Duals, never could get the bike tuned even with the Zippers auto tune in my bike. Canned maps didn't work and neither did the Zipper ThunderMax. I was told after banging my head against the wall for several months that the True Duals mess with the scavenging and do not work well with the stock TC 96 cam. I switched to the FuelMoto setup PCIII and DynoTuned mufflers, haven't had a problem since. Strange a few of these threads are popping up now.

 

I gave Keith a call since Jamie is entertaining his kids at the Indy 500 this weekend. His advice is to double-check that the two AT modules are on the correct cylinder. Module 1 must be on the front cylinder and module 2 on the rear. If not in their proper places the trims can get out of whack and start multiplying out of control like the OP describes.

 

The map I gave Scott is an unaltered one from Fuel Moto, and we all know they tune with performance and cooling as the top priority. Thus, their maps are rich in the cruise range, much more-so than I like for everyday cruising. That's why I have the map switch installed and have the best of both worlds.

 

The same thing happened to me after I accepted trims a couple of times. I was expecting the trims to be going down, but they didn't. I was told the same thing, that my modules were reversed, but they aren't. When I installed the system, I relabeled the autotune modules with large enough writing so that I could see it. (yes, the labels got on the correct modules). I triple checked on installation, and again after my bike began running worse.

So... if it's not that the autotune modules are reversed, then what?

What is the proper procedure for accepting trims.

What is the difference between send map and advance/demote map?

what is send table/get table?


I put the original FM map back on my PC, but now I've changed cams and will change my fuel map to the one Keith sent me for SE204 cams. I just got the bike back together, and ran it around the block with my current map, to make sure everything is working properly.

 

Man, I wish I understood this!

Kroozeabout.

 

Try upgrading to v1.0.3.3 of the PC software, as the older version (1.0.3.2) has been giving some problems along these lines. If this doesn't work and the modules are on the correct cylinders we may need to wait for Jamie to return from the races before going further with this. I sent him an email and hope to hear back from him on Sunday.

You don't really need to accept trims, as AT will work the same either way. In fact, if you are rigging a map switch like I did you'll create a rich base map by using rich Target AFR's, then accept trims only once, which creates a rich base map. See my write-up for more on using the switch. Then after adjusting the Target AFR's to leaner values for closed-loop mode (mileage) you just let AT do its thing by letting it trim to the leaner targets.

After making changes to your tables in the computer, you'll hit "Send Map" to send it to the PCV, and that sends the entire map (all tables) that's loaded on your computer at the time. Of course you must be connected via USB to the PCV to use any of the Send/Get commands.

Advance/demote map takes it in and out of advanced mode. Advance mode allows tuning both cylinders separately and thus gives you two tables instead of just one. You can advance/demote all of the adjustable tables (Fuel, Ignition, and Target AFR) individually if you want, but I don't know why you'd want to. OTOH, demoting Target AFR's would work fine if all values are the same for both cylinders, which they usually are. If you demote the map it shows only one table per item, thus one table of settings works for both cylinders. All PCV maps from Fuel Moto are advanced, so you should never need to change this setting.

Send Table sends only the table showing on your screen to the PCV. If you Get Table it is getting that table from the PCV and putting it on your screen. I've never used Send/Get Table, but rather work on my map and use Send Map when finished. The PC software should automatically Get Map from the PCV when you launch the program unless this feature is turned off in the settings.
