Bazzaz vs PC-V

[kerlyb]

I know these will be available soon for the RSV4. Yes I've heard all the comments on why the Aprilia Race ECU is the better option, but I want a custom map for my region and type of fuel.

Can anyone comment on which is better, based on your personal experience?

Bazzaz gets the nod from me. I have not used the Aprilia/Bazzaz yet, the beta kit just arrived yesterday so it may be a few weeks before I can post anything conclusive. We got the full monty kit for ours, Traction Control, quickshifter, o2 emulator, and more wires than the stock harness has I think. I will report back when I know more.

cant wait to hear more about the Bazzaz unit. The only issue I see is that there are several dynojet tuning centers but are any of these places going to be able to work with the bazzaz software or control unit?

Dyno Jet makes it easy for the average tuner to automatically generate a custom map quickly with their Tuning Link software (only works with Powercommanders).
But it is not always as good as it can be and requires manual fine tuning to get the best out of your motor.

That manual fine tuning ability is what separates the good tuners from the average tuners.

A good tuner can tune the Bazzaz or PCV.

If it's of any use, Bazzaz are ready to roll for the RSV4 now running traction, Q/S etc as Micah says in the UK for £699. Works at 500rpm intervals rather than PCv 250rpm so it's not so finely tuned but good enough.
PCv is still a way off for the V4 according to sources ...... as is Bike Interceptor

Also, Bazzaz can be used with other Q/S such as HM

I think I just saw that they are almost ready on the Austin Racing site.

I have been in contact with Dynojet for close to 2 years about the RSV4 PCV, still nothing firm at all from the USA Dynojet guys. I have a part number, but vaporware is basically what it is until I see a real unit in my hands.

Bazzaz is very intuitive to work with, the 500 rpm separation is actually a plus, there is no need for the PC style 250 rpm increments. Bazzaz stuff that I have used in the past kicks ass!

The "autotune" feature of the Dynojet dyno and PCIII/PCV is horrible in my experience...and I have a LOT of experience with it. Almost all the Japanese bikes and HD's I tune have already been "auto-tuned" and once the owners of said bikes decide that it still runs less well than they want they end up with me. With very short total lengths of exhaust plumbing used on any modern bike using straight lambda in a sweep test will result in very rich fueling off the bottom due to reversion in the pipe. There is one hell of a good reason the lambda probes in SBK exhausts systems are located on the header pipe, near the head. On the last Yoshi Suzuki I saw apart there were 4 small lambda sensor located about 5 inches from the head itself, just like a bigger version of where you would normally put EGT probes.

I have a Bazzaz unit sitting on a desk at the shop, it is real, not vapor.

Agree.

Anyone wanting a fuelling module now has to go Bazzaz with the added bonus of TC etc.

Dynojet are having problems with the motherboard and are months off.
Bike Interceptor CAN be made to work but has to be plumbed into the loom rather than Plug & Play. And that is only basic mapping without TC etc

I just looked over the Bazzaz stuff and it seems pretty basic. Would be very easy to make a competent tune and just about anyone familiar with how to tune a bike should be able to use it. No more difficult than the Dynojet stuff. I'd like to see a unit that can control timing, fuel trim measured by injector duty cycle, injector transition, and about double the resolution of what either has to offer. Along with data logging which is crucial IMO. Motec making a plug-in harness for our bikes yet? Still, with integrated TC and a QS, it's a pretty neat unit for little money and a not so steep learning curve.

Ordered mine from Austin this morning. I should be a bloody FX trader with all the calculations I've had to do over the past couple of months with our Aussie Peso.

I had very good experiences of running the Bazzaz units over the past couple of years on 08/09 Fireblades, the only issue was the quickshifter (hopefully now fixed by using an HM version) but the quality of connectors, feedback from my dyno guy etc was excellent and I hope, ride-by-wire notwithstanding, that I can get the RSV set up in a similar fashion.

There is some excellent information in the back issues of roadracingworld magazine on setting up the bazzaz TC parameters - will try to do a cut and paste.

Thank you

Does anyone know exactly how the Bazzaz unit will work with the "R", "S" and "T" modes? Will it be one "master" map that's active in all modes, and will torque still be limited as stock in "R" and "S" modes? What about throttle sensitivity, will it be unaffected, in other words dependant on the selected mode?

What about the QS function, is any other hardware required, or can it be used with the stock shifter or OEM rear set?

Do the TC function really work well without using a front wheel sensor?

Questions, questions.

Thanks very much Aussieracer!

I've got the file now, unfortunately it's in a form a bit different from what I expected; due to copyright, I can't post it here.

I'll be happy to email or pm it to anybody that needs it.

Sorry that I wasn't able to post it, but RRW takes their copyrighted stuff very seriously.
