Custom tuning confusion - help?

Hi all. Trying to get some clarity here so please forgive my stupid question.

I have a 2011 Storm with the TOR Shortys that it came with, running that tune. I've installed the wider mouth air intake cap and removed the CAT and it's popping like crazy (been running like this for months). Getting a little tired of the popping and I'm looking to get a custom tune, since I get the impression there's nothing available for my configuration.

I've contacted a dyno tuner and they're asking what they'll be using to upload a custom tune, if I have a Power Commander, etc.

When I had a Speed Triple I was just uploading tunes through TuneECU that I found on this board (hey, I'm not saying it was a GOOD idea, but it worked) through a OBD2 to USB cable connected to my ECU. Can we do the same thing on the TB?

Thanks

For a 2011 Storm, yes, you can use TuneECU to upload tunes. The LTs and Commanders are ECU locked so you can't load tunes to them. But you should be good to go. I've loaded a couple different tunes to my 2011 Storm that exact way.

Unless you know a dyno tuner who can use TuneECU to remap the fuel, you’ll only be able to use TuneECU to load someone else’s tune. All you’ve done is remove the cat which is causing the popping on decel at zero throttle. The TOR tune for the Storm should be reasonably close but you could have your dyno guy test the power and a/f.

If he’s a good tuner, the best you will do is a Power Commander (unless he has also used TuneECU). I had a 2012 and have a bunch of “custom” tunes that were floating around at the time. I’m not sure any of them could eliminate popping on decel at closed (0%) throttle. This would involve the L fuel tables if you look at the map in TuneECU. The stock L tables have a zero column to the left of the lowest MAP pressure. We tried adding fuel here in Rocket tunes but this didn’t work. You could play with it in TuneECU without much effort.

It’s easy to tune the popping out with a PCV. If you wanted to spend the money on one and install it, you could load a zero map (zero trims) and add 10-20% to the 0% throttle column. This gets rid of the popping. If you were lean or wanted more power, a dyno tuner could deal with that.

I see! Thanks for that...
What about Rexxer? It's a program one of the tuners around here uses for Triumphs.

I don’t know about this. The problem with remapping the Keihin ECU is that you can’t change the fuel in the ECU while the engine is running (I’m pretty sure). You have to run it on the dyno, see where it needs more or less fuel, turn the engine off, add or subtract fuel in the map, save the map, download it to the ECU, turn on the engine and see how it worked as far as power and a/f go. You have to do it in the L (map) and F (throttle) fuel tables at all of the load points. You also have to know the switch points between L and F, which you can see in TuneECU. You don’t want to turn off the L tables because manifold pressure is more sensitive to small changes in throttle opening at low throttle angle. Ask your Rexxer guy if he remaps the L tables, how long it would take, and how much $$.

PS: I see that Rexxer wants $130 for the OBD2 cable. I assume It’s USB. The Lonelec cable you use with TuneECU is about $25. Maybe there’s something special about Rexxer.

Another PS. In the 1700 map for TORs, it looks like it’s in closed loop, using the O2 sensor to lean it out, up to 4400 rpm at closed throttle. Since you have TuneECU and the cable, I would disable the O2 sensor in the tune. You should read the tune in the ECU to make sure it’s the TOR tune for the Storm.

What cat eliminator did you install? Make sure it's air tight and not leaking air around those connections.
