Hi guys,

This week I went to visit a motorcycle engine specialist with the aim to improve the performance of the bike working over the mapping.
I show him TUNEECU program and we made some trials over the dyno, I saw that is very slow to modify and adjust the mapping, point to point, with this program. This guy recomend me to install some kind of fuel tuning system (Dynojet, Bazzaz,..) if I want to go in the way to reach the optimum engine performance, with the advantadje that if some other changes are aplied to the bike, intake air box for example, then is easyer to remap.
Now I'm meditating what to do, to install this kind of unit and the map reajusting can cost me, minimum 600€ and I do not have so clear to reach a real improvement finaly. I have a great doubt with the balance € vs improvement.

My bike is the SUPERDUKE R 990 (2008) with akrapovic line and heads+BMC filter. The power result in dyno was 132cv.

My tendence is going to have the bike dedicate to the track.

I know that some of you have made a lot of trials and improvements installing powercomander or others in your bikes and I would like to know your opinión and if you have tried the results in a dyno (before and after the modifications).

I saw BAZZAZ have good prices. Has anybody tried it? WHat results have you reached?

Are you looking to do dyno mapping or on the road mapping? If on the road, Dynojet and Bazzaz both have this facility (although you'll need an additional box), which will map to your mods and riding style as you go.

Have you tried TuneECU yourself? Only asking as if you have, have a look and find a map that has similar mods to yourself, then download that map to your bike. It won't be an exact match/perfect fuelling for your bike, but will be pretty damn close, which will result in less dyno time if you think it needs finer tuning. This is all I've done with the mods up to now, I've had it running on maps from here for years and it's been fine for me.

I wouldn't expect much gain just because you fit PC or bazzaz, same results you get with tuneecu (find different garage, where guys simple know the software and how to use it), which is free. I think the most promising gain is behind proper air intake like motohooligan or CPR's rottweiler, I have a plan to get one of them as well (CPR, as there is no motohooligan anymore). Also feedback from users is very good (+/- 10% power/torque increase, but also make bike smoother).
Personally I would not go for PC3, if you want PC - buy PC5 with autotune modul, dyno it and then leave to autotune to do the rest.
I have PC3, but was already fitted together with dynojet QS when I purchased my bike.
I'm not sure that tuneecu is most difficult to tune the bike compared to Dynojest software. All what I know is that local specialist never mention to any of my friends that is hard to work with tuneecu when they visit him to tune bikes.

Wouldnt think you would get much more than 132HP anyway, not for a 600 euro spend. I did the same as Jambox and used TuneECU to upload a map from here with the same specs as my bike. Good improvement and 3 years trouble free.

the major difference between the Tune ECU and the dynojet software is the the dynojet power commander allows live mapping on the dyne, it is not necessary to download the map from the bike make an adjustment and then reapply the map - if your going to spend a lot of time doing dyno work then the ability to live map as you're making the runs is desirable if not then tune ECU will take a tiny bit longer to get the perfect tune installed but then you've saved on buying the PC?……alternatively buy a PC3 second hand? they don't usually go for more than £100….. My local dyno guy is more than happy to use either and even uses the two in combination on mine sometimes…...

Yesterday I was checking TUNEECU in dyno with the workshop guy. Trying to adjust the mixture AIR/GAS to the theorical perfect point. With the aim to see the reaction of the engine. We started from the map done for my bike configuration (from TUNEECU web).

We observe slow process between the map modification and the try in dyno if you take in account that you have to do the process for every throttle position (%) vs rpm. It seems a long time process.

I'm not completely sure, but in the case of dynojet or bazzaz, can be connected a module that can permit to do a kind of autotune in dyno. Then you can reduce the mapping time for example from 4 to 0.5 hours.
Then if you want, for example, to change the airbox one month later and you need to remap other time, you can win in remaping time.

My real cuestión is if after to do this kind of things realy the bike will improve its performance.

Talking about the airbox, until now I have not seen a real comparation between BMC or KLN filters with serial airbox vs CPR, motohooligan or DNA airboxes with dyno results between before and after with the same SUPERDUKE R. I'm not so confident about this airboxes until now.

Have you seen this kind of comparison?

In my opinion results are the same whatever you use. Depends on the tuner and the time you wish to spend.
Dynojet stuff is faster as the dynojet dyno/software basically loads it straight in the PCV or 3.
Use a calculator to see what the tuner charges you an hour and see if it is worthwhile buying a PCV.
Tip, do all your mods BEFORE dynotuning!

Another advantage of TuneECU is you can tune the 2nd flies and alter ignition timing. Like others have said you have to take into account what you would spend on a piece of hardware against the extra time it takes to Dyno using TuneECU. I would also buy a CPR if I were you.

solve all your issues in one go with this….Tom's a good lad and well known to the Crashfest crowd - he's just having a bit of a motorbike identity crisis at the moment!
