Here is my long promised thread for discussions and resources on how to tune your Indian motorcycles...TS111, TS116, Scouts 60 & 69, & FTR-1200. The main information I will be providing is through my Indian Roadmaster Blog, which I have turned into an Indian tuning related site only. Please read and reference that blog. If you have questions or comments please do it here so others will have the benefit of the Q&A. There are no dumb questions, so do not hesitate to post. Feel free to copy and paste from that blog here to clarify any questions you may have. I hope the blog will serve as a good reference for your tuning efforts, print it out and use it as a resourse.

The reference blog is here: My Indian Roadmaster Blog

This is a big effort and I am slowly rolling out the information. I will not be going over all the tables in a tune, but will hit on the most important. Please feel free to ask questions on the other tables and we will discuss in this thread. My goal is for you to be able to safely manipulate your tune and through logging of data, make your own corrections. I will be supplying the equations I have written in conjunction with our friend @cmoalem. I have modified these equations to take out the Wideband portion of the equations since this is to support non-commercial tuning. If there are any Python wizards here, please feel free to modify and better these equations and share with me and others.

Finally, I do not claim to be an expert. If I provide any information that is not correct, please post the correction or DM me. We are all here to learn as much as possible in the very short time we are given on the Earth....let's be kind to each other in this thread and perhaps we can demystify this thing called engine tuning.
@CraigB1960 is a gentleman's gentleman!!!

I have been tuning using the script file from Dyno Jet, should I continue tuning the with the script file from you blog or should I start over when I use your script file?
Mine is a lot better, tunes all three tables in one pass. There is no reason to start over, just start using mine.

Your tune will zero in quickly with my equation, your effort to date has not been a waste.

Thanks for the thread. Exactly what I needed. Finally, I do not claim to be an expert. Because we have very little time, we need to learn as much as possible. That's why I turned to https://edubirdie.com/write-my-thesis in order so I would write my thesis and save time for my discoveries.....let's be kind to each other in this thread, and perhaps we can demystify this thing called engine tuning.

I added more content this evening. I will be providing a second equation this weekend to correct for VE Table & Injector Compensation Factor - Front & Rear tables. The use of this equation is the same as the VE & IPW Comp Table equation. I rarely correct the ICF Tables anymore, usually leave them all 1.00's. However if you want to fine tune you engine, these tables are the ones to correct.

Added more content today, which wraps up tuning the fuel tables. Next post and video will deal with one of the most confusing tables, the Mass Flow Through the Throttle Body. I will discuss what it is and how to tune it using an equation I provide.

If you like these series, be sure to hit the like button on the video and subscribe. It will help drive other users to it that might want information on motorcycle tuning (or ATV as well).

@CraigB1960 i’m really enjoying reading through your blog and attempting to glean a fraction of the knowledge you are lying out for us. I really appreciate it and look forward to more updates. Since I already have 1 bike that is tuned, I’m simply looking at the software, stock and modified tunes, and noticing differences. Thanks again.

Well @CraigB1960 I finally got the courage up to try my hand at making a tune from my stock file last night after reading through your blog and watching some videos. I was really surprised this morning that the tune I modified, using your tutorial examples of course, runs so much smoother and no decel pop like the FM tune I had on it (which by the way was acquired after you left them).

I tried some datalogging this morning on the ride to work but when I got here the PV3 said it had disconnected from the bike. Not sure what that is about but I'll try to mount it on my handlebars on the way home and hopefully get some valuable log files.

I have a couple questions for you if you have the time:
  • I have a completely stock MY '16 TS111 engine, with my own diy intake, no cat, and Indian stage 1 pipes that I acquired used. So I don't have any Indian stage 1 card download or anything. Is this ok to start with or should I look at getting a stage 1 card then start over?
  • I thought I read or heard you say somewhere that there was something you did to a tune when the bike no longer had the catalytic converter in it. But I can't find that now, can you expound on this please?
Thanks in advance!

Should not have any issues with a 2016 disconnecting. Be sure that when you start your bike with the PV3 connected that once you power on the bike, do not start it until you see that the PV3 is displaying data on its display.

You do not need the stage 1 factory flash, it is a waste of money. However it is good to start off with the settings that it has. If you send me your STK file, I will send you the recommended starting DJT. Send it to me at indiantuning at gmail.

There are no special settings for CAT versus non-CAT.

BTW, congratulations! Tuning your bike is very easy and once you do it a couple of times it becomes addictive. You will find it to be a source of satisfaction when you start to notice the improvements you make.

I will get it sent to you this evening when I get back to my laptop. I'm very interested to see the tune I created compared to yours. Thank you

I loaded your tune this morning and it's running great so far. I tried taking some log files but I keep getting an 'error 201' code on the PV3. I think I may have an issue with a loose connection in my bike somewhere. Anyway it will let me log for 10-15 min then it cuts out. I hit the return key to get off of the error screen, then the circle again, and it says log stored. So at least I have something to work with anyway.

Is there a way to combine log files if I can only gather 10 min periods at a time?

You do not need to combine them, just load the logs files in Data Center. My videos show this. You can load in as many logs as you like, though the default is 16 IIRC.

Hello my fellow tuners, my name is Jake. I got my PV3 about a month ago, and have been tuning my 2018 Chief Dark Horse which I got in 2019. I live in Minnesota and ride as early and late in the year as weather permits me to. My bike has no performance upgrades, I've only added an external breather for crankcase vent, and a K&N air filter because it's economical, and before the breather, I was oiling my paper ones which I didn't like. OK, I guess you might say iridium plugs are a performance upgrade, which I installed whenever they were due to be replaced. Anyhow, my goal is to learn the tuning process, tune my bike to perfection, and maybe a Chieftain if I finally upgrade like I've been dreaming about. I have yet to reach 40+ mpg since owning my bike, and my tuning goal is to improve gas mileage and dial in the tune for my riding style. I really enjoy tinkering and thought buying the tuner was probably the best money spent as far as performance upgrades go. My tune has some mild changes to DBW, idle, and delay for fuel cut off, as well as raised limits beyond the bikes ability for speed. I've done good logs and one pass with the equation on this tune. I had a version of it that had 2 passes and some other changes including a more aggressive twist grip, but it ended up with some idle surging and I reverted to the version I knew and liked and started over with the logging. Looking forward to learning and sharing what I can here.

Thanks again. I haven’t been able to watch all of the videos yet in detail due to really poor internet here in the back woods of Mississippi.

Hey Craig - just logged my first ride this morning - seemed to go smoothly - I'll do another on the way home.
I've been studying your blog, and watching the videos - someday soon I'll be brave enough to open up the Powercore program, run your equation, and check out the VE and IPW tables - first I need a new PC. It seems my tower is not upgradeable. :ROFLMAO:
Having a hotrod background I'm very comfortable with carburetors and Vertex magnetos... without your instruction there's no way I'd be digging into this computer "stuff". Thanks again for all the time you're putting into this project - it's obvious you can do this in your sleep. From experience in my own field, I know it's sometimes difficult to break things down simply enough for those who haven't been at it for years.
