O2 temp manipulator vs O2 sensor maniupulator - Ducati.ms

My bike pretty much stalls every time I cold start it. I was thinking Id get some fatducs but I just went to go out for a ride and its around 50F and the bike started up and ran at a higher rpm and never acted like it was gonna stall. The bike also ran better below 3k and was able to put around 2k no problem. Which do you think would be a better fix. A temp manipulator or AFR manipulator. Thanks

If the problem you are trying to fix is your stated cold start stalling, neither option you mention is going to properly address whatever your problem is. You have something else going on. Regardless of the closed loop lean running issues, these bikes should start cold and warm up fine without stalling if everything is working right. I left my house this AM at 29 degrees and rode right off with no problem just like usual. 50 degrees, must be nice.

I know it wont fix just that problem but it also runs like shit below 3k if its semi warm. I have had a dealer look at the stalling issue before and they figured the TPS needed to be reset and it was and I guess it fixed it for a short period. The problem is the dealers are far away(100+ miles). I just found it interesting how much better it ran when it was "cold" outside

This will be my second winter with a set of fatducs installed, and while the bike runs well in warmer temps with the devices, it does seem to run a bit smoother when it is cooler.

YMMV

Is it your perception that it runs better in all respects (warm weather or cold) with the fatducs over stock? In other words, are there any penalties to the fatducs, or are they equal or superior to stock in all respects?

My bike ran like crap when I first got it, and it definitely runs better with the fatducs. In hot weather I may get a small 3k stumble once in a while, when the weather cools down, the bike runs just about flawlessly. Overall, I just don't consider fueling an issue with the bike anymore.

Lucky I guess.

Yes

No

Better in all respects, but then again, I am running both.

Yeah, yeah, I know, ... it's not supposed to work, ... but it does.

For me the temp manipulator from shiftt tec was just a waste of money.
Ran with and without fatducs and have settled on fatducs as the best option so far (short of dyno tuning)
Temp manipulator caused a huge hesitation on quick throttle.

I have mivv decat with miv muffler and noise baffle.
