Well I plugged my PV into my bike.
Theres no map for my combo in the pre-configured DynoJet maps.
The custom tunes have one slot populated but it isn't labeled as my configuration.
It reads "switchback" something or other.
Everybody else have that?

Did you buy your PV from Fuel Moto?

Bike is a 2002 softail.
I'm running the autotune wideband pro kit. I've done several autotune sessions, and I've got all of my changes down to less than 1%. im confident I've gotten my fuel tables dialed.
When riding and watching the gauges while logging I've noticed a few things.
When commanding 14.5 ratio, my afr never goes below 15.
I set the fuel table to 13 across the board, which I think is where autotune pro sets them at. I ran about a 20 minute log. City driving and I got on the interstate. I opened log file with excel, sorted by rpm, split groups in 1000 rpm increments, and averaged what the actual afr was for each cylinder.
In all rpm groupings for both cylinders I was averaging about 12.85 when commanding 13. Pretty good in my opinion. I'd rather be on the rich side.
I did the same thing with the normal fuel table which is set to 14.5 and my averages for all rpm ranges was over 15.25. Some ranges up to 15.8 on varying cyclinders. The rear was consistently the leaner of the two.
Any ideas on this? Could this be O2 sensor error? How can I get this right?

What is it that you are trying to do, or what problem are you now trying to solve? Are you looking to set the AFR across the board? I would strongly suggest you set your cruise range, anything from 30-60KPa and anything from 750-3Krpm at the 14.6 level. otherwise you'll just be loading up the cylinders with rich mixture when it doesn't need it, running the risk of running way to rich for a lot of riding time (if this is a street bike?) and fouling plugs.
Most of my 107" build from Fuel Moto runs in the 13.8 to 13.2 range and it is only at WOT that it drops to 12.8, also, what is your Closed Loop Bias set at? MIne is 700 across the board.

Looking for some help on decel pop
Need some help with Decel popping. Some background, my bike is a 2010 SG running a arlen ness Beveled Inverted Air Cleaner with a 2011 stock exhaust with the baffles removed. running a power vision.
I'm struggling to remove the decel popping which happens between 1st and second.
I have a fuel moto map. FM (Jamie) who has been great with help on maps but still have no luck removing the popping. I have checked all the gaskets and have no leaks which I can tell. So I took the last map which FM created and have run 6 auto tunes on it with a little better results. So can anyone take a look at the base map and the last auto tune to see what is changed maybe recommend some changes to help with this problem?

Thanks guys.

What have you got for engine mods on this bike that you you're running Autotune Pro? I assume you mean you have the Dynojet Autotune Pro kit with the wide band sensors?
What is it that you are trying to do, or what problem are you now trying to solve? Are you looking to set the AFR across the board? I would strongly suggest you set your cruise range, anything from 30-60KPa and anything from 750-3Krpm at the 14.6 level. otherwise you'll just be loading up the cylinders with rich mixture when it doesn't need it, running the risk of running way to rich for a lot of riding time (if this is a street bike?) and fouling plugs.

I'm using the fuel table fmoto sent me. 14.5 afr in cruise area, O2 sensors are reporting over 15. I set the cruise aree to 14.2 now I'm getting 14.5.
Thanks for your reply

Exactly. I do not have a switchback.
Ive got a Street Bob with Arlen Ness & Bassani Mega Power.
I did get it from Fuel Moto (mapped by Jamie) and specified my mods.
I called them to inquire and they said they've got lots of "cross tunes" that work on many bikes and not to sweat it.
Said it shouldn't be a problem.
Appreciate the response.

No, you have a bike from the Dyna family. (Street bob, wide glide, fat bob, low rider, street bob. And switchback)
The tunes are the same.
For the big twins, you have the touring line, dyna, and softails.
Don't sweat it.

I run my idle / cruise AFR at 13.8, which suits me better on a town bike. 13.8 is not gassy by any means, but it is also not Prius-economical like running closed loop 14.6. Main thing for me is keeping ET's down in town, 13.8 works much better at least from reviewing my data logs. I only suffer on MPG when I get heavy-handed.
But, I could not get the ECM to accurately hit any open loop AFR's unless my VE's are somewhat accurate for engine and parts combo. I tried DJ's canned map and even one their lead dyno tech sent me, which was also nothing more than a canned map. These were all way too lean on the VE's. Fortunately a good member here gave me some direction and assisted with correct tune files, and I have since further educated myself on how the Delphi system works.
