I keep hearing about obscure shops flashing ECUs, and how that adds HPs to the bike. What's the difference between a flashed unit and a fuel delivery module, like PCV and Bazza? Can you have both?

Not much info on cbr's with flashed ECU's OTF,have only seen one thread on this.

it was expensive ($500 IIRC)

Most seem to go with the HRC ECU.

An HRC unit is the best way to go. It is always adjustable. A flashed ECU rewrites the parameters and to change you have to flash it again.

Most top racers will use them together. Here is why in short.

A fuel control unit only allows you to add or lessen fuel delivered to the engine.

A flash or kit ecu allows you to change many many more things. timing, secondary throttle plate maps, small oem functions like butterfly valves can be eliminated and the list can go on depending on the bike model.

To get the most out of your engine you need both units. For the street rider a fuel control unit is plenty.

But....in my opinion, bang for the buck is ecu mod (flash only). Your throttle response, hp gains and bike smoothness are all improved.
You can send it to someone who knows what your bike needs and boom plug and play. I even wrote my pcv map onto my zx6r ecu.

I say flash only as an hrc kit ecu plus wiring is prob almost $1000.Plus the cost of having someone program it to what you need. I am new to honda but this was a cost for my zx6r. I figure it would be roughly the same

This is a very very short answer. I don't want to type for an hour. haha
Hope it helps you in your decision.

What bothers me is how can a small shop possibly know all the correct parameters you mentioned for a cbr600rr, let alone the multitude of bike engines and modifications out there?

But I do see the difference now, I guess it can be said that PCV and Bazza are only a subset of the ECU modifications.

Small shops will not know how to set an ECU. It is really done by highly experienced tuners. Properly done it is always done on a dyno with days of trials.

A small shop with an adequate tuner can map a fuel controller.

The only hope that anyone with little experience tuning bikes would have at doing an ecu is that they have been around for so long in the 7-15 generation that there is a wealth of knowledge out there and they may be able to get in the vicinity of what should be done.

So let me ask you, where did you have your ECU done? Did you flash it yourself?

Search OTF there is /was a thread on this.

IIRC......not many owners have done this ,and I only heard about this one co. that has gone to the effort of getting into the code.

Reflash was $500!

Isn't there a smart O2 you can put on your bike that will do this? I thought I read that somewhere, i'm suspicious if it would work though.

On my Kawi I had a guy i know do it but it is not 100% correct.

On my Honda it was done by The tuner for Honda Canad's race team.

For a good base try ECU unleashed. They can get you great improvements but it won't be an exact flash.
