    G'day all. Now I am in the world of a FI bike I am looking for a good tune for better fuel economy and general reliability. My bike had a shop tune done on it but I was told to get a custom tune on a dyno by someone else. Trouble is for me the idea of revving my bike in forth gear from just over idle to hitting the rev limiter six or seven times on the dyno leaves me feeling a anxious. Btw I never ride my bike much over 3000 revs so would there be any real benefit in getting a custom tune. Oh yeah I was quoted $500 for this custom tune and starting to miss my old carby Evo a lot simpler to tune.

    Can it damage: yes, seen plenty of bikes and cars explode on dynos
    Is it worth it: no (IMO).  You may get a few HP, but unless you've done significant engine mods, you won't get that much more than an add on tuner.

    Good tune is not just WOT numbers, bike runs better, cooler stronger everywhere, tuned plenty of stock bikes for blokes that are still smiling, your bike, your call.

    most important, what you need is a good operator!!
    and tell him how you ride.  Problem is not many know how to tune, and a good operator will ask you how high you want yo limit the rev's at, if like you say you don't normally go past 3,000 , I would say, a good operator would set your rev limit at say 5,500. but on EFI a full custom map takes about all day to do. BUT when done right the bike will be beautiful to ride, needs to be experienced to believe !! It's not about numbers, but how quickly & smoothly your HP & TQ delivered. after all a rider who stays around 3,000 , not a racer.

    Sorry Chaser  i disagree. Its not about chasing those last few hp but smoothing out the curves and allowing the motor to acheive its best VE and AFR

    It's horses for courses.  In a high performance application, yes $500 would be well spent on a Dyno tune.  But in this instance where the guy says: "Btw I never ride my bike much over 3000 revs so would there be any real benefit in getting a custom tune".  I would say no.  I'd rather spend the $500 on a good flash tuner in that scenario.

    I think that the point trying to be made here is that with a dyno tune the bike is still going to be a lot more friendly to ride with a crisper throttle response and smoother than a simple flash tune. Now if you got a tuner with wideband 02 sensors ......

    Thundermax tuner. Best money you will ever spend. No dyno necessary. Auto tunes. Excellent.

    If a dyno tune kills your engine, it was probably going to grenade itself somewhere down the track anyway. If your engine is healthy, you'll be fine.

    I’ll echo the comments of others. A GOOD dyno tuner working on a stock or well put together bike will create great benefit with minimal risk. You’d be surprised at how much smoother a bike will run in the rev range you and most of us ride at all the time. As summer comes into play, it’s all the more important to have a good tune as without it bikes run very hot and under load are more inclined to ping at times. 

    I wouldn’t trust any tuner though as many spend minimal time and will simply give you a print out of the chart at wide open throttle. A proper tune will focus across all throttle positions and loads. And pretty simple to tell them you don’t want the bike revved above x rpm if that’s your concern. Hardly matters if your bike is perfectly tuned or not above 5,000rpm if you never ride there anyway. 

    I’m personally not a fan of replacing the Delphi ecu with a Thundermax as the Delphi unit works perfectly well and reliably. The Thundermax ecus  reportedly work well until they don’t work at all. Plenty more of them failing than the stock Delphi ecu. Flash tune the Delphi ecu I reckon

    Thanks for the replies so far. Yes I not really worried about trying to find as much HP as possible I just don't ride that hard. Fuel economy and reliability is my number one concern and I feel with my stage 1 on my 96 cube motor is enough to keep me happy. Anyway a lot to think about so far the shop tune seems ok just at times I think I might not be getting the best fuel economy but then again I am comparing my old Evo Heritage to my twin cam Heritage cheers.

    should get better mileage out of a properly tuned fuel injected bike

    Can you get a “good” tune for $500? 
    I thought they were more like $800 as they should take a while.

    Where I live I am three and half away from a major city. There is one shop with a dyno in my area and he quoted me that price.

    Well seems a good deal for a personal tune. As the guys have said, set the limit at 5,500 or given your ride style even 5,000rpm, no worries. 😎

    Well, I don't know about cost, as a lot of things effect what it will cost.
    Like if operator has a brand new Dyno, with expensive equipment. Like Type of sniffer they are using . ( to get AFR ) as the real accurate ones can have the sensors damaged if motor burning oil, so cost go up for the operator ( owner of Dyno ) & if operator owns the shop dyno is in, or if they lease it.
    For what you want, not that important what make or model dyno is, just as long as operator familiar with your software & can tune. I'd say for you 5,000 would be high enough to ask to have rev limited. but you sometimes need a few more rev's in emergency's.Also when they are tuned right, they respond quicker & smoother, so if you have to open it quick to get out the way or some other reason, you could find your rev's have gone up a lot quicker than normal & when you hit rev limit can feel like a brick wall ( mostly if in a lower gear )
