Thundermax help
I’ve been using the Thundermax with zero issues for about a year now. All the base tunes are super rich and I’ve made adjustments accordingly to get my bike to run like stock while cruising and a nice little bump in power when I call for it. Last night I opened the software to make some changes and it auto downloaded the newest update for the software. I made my changes, plugged into my bike, and it uploaded a completely stock basetune with no corrections! I’ve been working for hours trying to figure it out and none of the copy/past hot keys actually upload to the bike. If I manually correct all the target afr points they upload... but get this, it still doesn’t change the targeted afr. Anyone else having problems with this system or have a suggestion to try? As of now I did a manual lock to target 13.8afr no matter what. Best I can do at the moment. It’s a 2011 dyna fxdf fatbob.

Man I don't know what to tell ya here.
I was screwing around with the TM software to edit a tune and I don't know how anyone tunes that ECU on a dyno. It seems the software and whole system is designed to literally be plug in and forget.
I tried to have a look at a timing map for an old engine and all it was it random graphs. No numbers or edit points. Sure you can move them up and down but otherwise, what the hell was I looking at...
Needless to say I shut it down and pulled up a PV map then copied that to my SERTP.
I dunno if that helps at all! You might have to use your saved edited tune as the base tune now instead of the canned tune the software installed.

that's the thing, my tune is still based off of one of the base tunes the system comes pre-loaded with. which is what was already on the bike as well. I made some corrections to idle afr as well as closed throttle deceleration on multiple rpm graphs. but when I wrote it to the ecu they all reverted back to the original base tune. I messed with it all day today and managed to manually change all the target points back to where I had them while being connected to the bike, wrote it to the ecu again and they stayed. where it shows yellow dots for what they used to be on the graph and blue dots (or red if im hooked to the ecu) of where I moved them to. but when I monitor the data, its still auto correcting to the old targets of the yellow marks on the graphs. yeah the system took me a while to figure out as well being the graphs don't look like any other tuning software ive seen. but it equates to the same information and ive had no problems tuning the bike. the autotune function only adjusts injector ms to adjust the actual afr to what you have selected in the target afr graphs. but even though my target will be at lets say 14.2 at said rpm and throttle percentage I can see its still trying to auto tune to the 13.0 from the base tune. im gonna ride it to work in the morning and see if my work laptop still has the older version and my tune on it. as of now I have locked afr to 13.8 to make it rideable.

before the update I could change targeted afr and watch it work toward those targets with each automap. now no matter what I do it targeting 12.8 idle, 13.5 cruising, and 13-12.5 at wot. basically getting under 20mpg now instead of 50 like I was getting

When you by a Tmax, it don't have any map loaded.
When making changes to a existing map you need to download the map from the unit, make you edits and upload it back. During this process you should save the map when first downloaded make you changes, save again under new name (incrementing a number on the file name), then upload the map.

As I stated, I’ve been using the system for about a year now with zero issues. I’ve made changes to my map plenty of times. I had the exact same map pulled up on my laptop that was already uploaded into the ecu, I made my changes, and wrote it to the ecu again. It wiped out all my changes and loaded a stock base map. The hotkeys off copying on graph and pasting it to another no longer update to the ecu. Only works if you manually change each data point on each graph. Even after doing so, once all those data points have been adjusted and successfully written to the ecu where it shows hem as red dots vs the basetune as yellow dots, it still targets the yellow dots of the basetune for the afr vs what I’ve corrected it to

I used my laptop at work with the previous version of he software. Everything works normally. Thundermax asked me to delete the software bundle and re download it from their site saying something may have went wrong downloading the update. I will do so tomorrow evening and let you know. As for now, thankfully the older version was still on my other laptop and I was able to get my bike back to running good
