My fuel pack sucks, tried 5 different maps I still have increase 17 to 3 for cold stalling & the decell pop is horrible. The dealer wants $650 to put inn a tuner. I want to contact V&H & get my money back. I can't afford $225 to through it away they need to step up & be responsible for there product! I never heard of fuel moto, will they stand behind their product? If they can't tune out the decell pop will they take it back?
What bike and what cams? Did they have your cams map?
My 09 96 runs very hot as well, even having a very good tune not 300 degrees, but it had approached it before in the summer.
I put on an oil bud cooler and that knocked down the temp @ least 35 degrees.
It is the biggest and most expensive oil cooler on the market but it does what it is purported to do.
My local dealer says that the new-er bikes run hot and that 300 is not out of the norm.
I feel that this is not so though and will do everything to keep the heat down.
Was that your only issue with the Rev Perf, was that the heat could not be turned down?
Initially that was my only problem...but after calling a few times and they would not discuss what to do to fix it---it was just send it back and we will make some adjustments....it's a locked box and you can't do anything to it without them.
And to address the auto tune question.......the "auto tune" function is only as good as the parameters the computer is trying to hit...with a TTS you have the option of going in to adjust the map and the computer will try to make the eng run within those settings..the EMS is doing the same thing only Revolutiuon performance locks the ECM and they are the only ones that can tell the ECM what settings to follow.
You are correct..mostly......even the EMS must use baseline settings for the readings it is trying to achieve. I had to send my ECM back 3 times and to me the bike is still not running the way it should.....They are dealing mostly with AFR and trying to set it up for good fuel mileage--which is not a bad thing, however when the bike is running lean enough that I can feel the difference in heat--that's not good. Sent it back a few time for them to adjust the AFR baseline and still not happy. My last bike with the TTS didn't run this hot--and it was the same model and motor. At least with the TTS, if I want to change something I can connect my laptop, with the EMS if something is not right the ECM needs to be sent back to them to adjust. What's the big mystery??? Couldn't the customer have access as well--Even if they claim he will never need it?? The part that bothered me was the lack of info...you would tell them what you feel and they say "send it back and we will make some adjustments"--how many times will I need to do this?
The canned map that is being supplied with the TTS is made from a dyno session with my motor/cam/air cleaner/ exhaust combo and if it's anywhere near as close as the last time I did this, I won't even need to tweak it. The EMS is basically using the same parameters for all bikes and the system is trying to reach those parameters no matter what your setup happens to be. Nice in theory, but it didn't really work for me. Some people are happy with it and that's great......
First negative experience I've seen in my searches on the rev.performance ems.

I have spoken to some other people who have removed the system as well......for some reason it does not seem to be getting written about......it just quietly comes off and something else replaces it.
Every tuner has/had it's issues it seems.
There's negative reviews on the majority of them on this site.
However I've heard more much more good than bad about the EMS.
Rev Perf. will do what ever it is they have to make it work right, including buying your particular cams, installing them and getting the right base map for your configuration. I don't think too many other's will do that.
There is a guy on this site that they did exactly that for actually.

That's interesting since the product as advertised is supposed to "learn" what the bike needs and should be able to compensate for cam replacement. As far as I knew, the only thing you could not do is change displacement or injectors.
I have had my Fuel Pak now for 40,000 miles. Never had an issue. My bike runs cool, gets around 36/40 per gallon consistently, my spark plugs burn clean with no signs of any issues. So, for some of us, the Fuel Pak works just fine. Some call it a patch others like it....so, there ya go.
I had a Fuel Pak on my '07 RK. It worked very well with my SE intake and Samson slip-ons. IMHO, a fuel pak works well for someone like me. I just want to set it, forget it and ride as much as I can. If you like to tinker, there are much better products.
I believe that all tuners need to have a base map though to work off of..
I saw a video on youtube from rev. perf. and they do claim that the only time you would ever need to send the ecm in to get recalibrated a second time is if you go over 20% displacement or change injector's. I think i'm still going to use it but I'm gonna wait till I do my build then send the ecm in to get recalibrated. It just seem's so simple and I'm not very good with computer's,guess i'm afraid to mess with the thundermax.
As for the v&h fuelpack I had one on my 07 nightster that I traded in on the RK,nightster had v&h sideshot's and a doherty power pacc air cleaner and that thing ripped and sounded awesome no decel pop or anything.
Sound's like the bike's with tbw are having the trouble.
