TTS Mastertune Information

That large block in red are the original settings for closed loop. They may start at 750 RPM's and go through 4500 RPM's.. from 30 to 80 kpa for your map.

Yes I understand they're still in closed loop, but ...
My question is, in the new map after click "Set to Original", most of the cells are still at 14.6, so they're running in closed loop. I was expecting most of the cells to be open loop after tuning is performed, is this not the case? If not, then what's changing for those cells (well, for the engine operation points that the cells represent, as controlled by the map file)?

I wantd to establish that you were actually in the original setting for your AFR and not still in the 14.6 across the board for VTuning. Tough to tell from here.
Why would you expect the cells to be in open loop after VTuning? You set it back to the "original" AFR table and the original table is mostly closed loop. . If you want to run in open loop you must manually change each cell. This will defeat the ECM's effect on your map by eliminating the feedback data from the 02 sensors.
VTune only changes the VE tables for the front and rear cylinders. You can view your changes in the VE tables by selecting Compare edits to original in the Table Comparison menu.

I like that I have these tools that let me visualize my bike's operation, now I just have to understand how best to take advantage of it. Thanks for your help.

EFI Upgrade
Hi Guys
I live in Thailand but at the moment I am in Algeria working. I just purchased a 2004 Night Train and it is being delivered while I am at work. It has a stock EFI and I want to purchase the TTS Mastertune as to be honest I don't fancy a Thai mechanic messing with my ride. I believe the '04 EFI does not have O2 sensors and therefore cannot make use of the V Tune. What does it take to upgrade to a later model EFI and fit the sensors to be able to use the closed loop for tuning. Sorry if this has been asked before but the thread is too big to go through all of it. I would like to stay with stock Harley parts and am not trying to create a racing bike just one I can maintain myself.
Cheers, Tony

I believe you can buy a kit from Doc, or some other outfit. The kit has the O2 sensors and cable harness, perhaps bungs to weld into the pipes. You will likely need a later model ECU. If no one chimes in with more info, I'll take a look at my archives when I get back to the house, but that won't be till tomorrow.

I personally have never used this, but some on this forum have and have had good results. If you do a bit of reading up on this you will find that you can make your own sensors and log data that can be applied to tools such as the PC or the SERT maps. This may save you from modifying your bike too much:

Why can't a guy simply buy the stock 02 sensors, wire them up to the ECM and use the sampling tubes for VTune runs with the TTS without having to purchase a TSII with WEGO? Once complete he can remove the sampling tubes and sensors then set his closed loop AFR cells one click richer to open loop... bam... good to go

1-352-404-6999 but they aren't in right now... must be Friday the 13th or sumpting. Tell him to send a cup of coffee to Thailand, that will get a good laugh out of him.
