Whats the best HRC ECU for stock 07?

[OONKS]

Im trying to figure out which HRC ECU is best for a stock CBR1KRR7(JSB, WSB, etc). Who do I need to talk to to get one and the components for it(harness, software, etc).

Thanks in advance!

Before you ask those questions you should ask..

What are you doing when you get the "magical" ecu?

Hopefully not planning on leaving it stock..the whole point of an hrc ecu is so it can accommodate the performance parts put on the machine so that it can be ran to its max potential. An ECU alone won't improve anything that'll benefit you from a stock bike..$.02

Im looking to start working towards building the engine up and that would be an incentive for myself to do so. A little bit at a time.

I got ya, but yea it's not gonna matter just having an ecu

Getting a ECU before you do the mods you plan on doing is pointless because each ECU is designed for specific mods. Atleast have a garunteed plan before buying a ecu, so you can gather parts then install all at once. With my mods I need the SBK ECU, which unfortanetly for me is nearly impossible to find for an 04. I know the SBK is for my build, i couldnt tell you specifically what the others are designed for but i know if you use the search button, you will find out the info you need because that is how i found out about the ECU's. Plenty of threads on them

To answer the direct question that was asked: HRC Basic Racer ECU.

The Basic Racer ECU is not fully adjustable (such as the HRC SBK,JSB, and JSB-E ECUs) but has a richer fuel map for lower RPMs over the Stock unit since it does not have any emissions settings in it. Redline is also raised to 13k which is 750 RPM over the stock 06-07 ECU. This ECU is pretty close to that of the OEM unit yet with more 'kick'.

Would also be a good idea to upgrade the intake valve springs as the 'slightly' higher RPM might cause a valve to float. More of an issue with the JSB and SBK unit though (13.5K, 13.75K)

You can utilize the stock wiring harness yet will have to make a few modifications as the HRC ECUs do not recognize the clutch sensor nor the kick-stand sensor (etc).

Guy has to start somewhere; not everyone has the budget nor desire for a performance monster.
