A cheap one here if you are quick: Dynojet PowerCommander PC III for Honda CBR 1000RR 08 with O2 eliminator | eBay (its not mine!)
yea mate i got it, probably be jan by the time i get it (from Slovenia) I thought the PC3's were just plug and play? and dont need any additional stuff? (at least the gsxr's were) but this is the first honda i've owned
the pc3's only control the 1 st bank of injecters,the blade has a secondry set aswell,so need the ign. module to control them.
The pc5 can't interact with upper injectors either without an ign module either but both of them can still be used quite successfully without the addition of the ign module especially road bikes where the secondary/upper injectors are rarely in use! Only the Bazzaz system can interact with upper injectors out the box. Oh an Suzuki use a similar lower & upper injection setup!
Thought as much ... What are the upper injectors actually used for then on these bikes? Why eight injectors?
They add in extra fuel when the bike hits around and above 10k rpm. Dynojet say very little benefit is gained from adjusting the fuelling on upper injectors on stock motors but can be of big benefit if a lot of internal engine mods have been carried out.
I tell a lie, I mistook the mentioned ign module for the secondary fuel module (SFM)! The SFM allows connection to and adjustment of upper injectors. The ign module allows connection and addition of dynojects quickshifter, the ign module also allows adjustments to be made to the bikes electronic ignition timing. Both are optional units!
I would rather go down another route and go for a seperate HM quickshifter unit than dynojet's quickshifter if I am honest. And you would also need to buy two aditional modules from dynojet to get the functionality you mention.
Too many additional modules ... All you need is a power commander for tuning and a HRC quickshifter for any road bike and even that's good enough for track work. I'd only consider the ignition module and secondary fuel module if the engine was high tuned or a race bike.
i know,one of the reasons bazzaz are a better unit than the DJ (imo) just letting the op know more than anything else.
Never used the Bazzaz system but it does come with a lot of features that the dynojet system needs bolt On units to gain same or similar functionality and with the blade's and indeed most sportsbikes boot space at a premium even more so on blades equipped with the wonderful Honda abs system the single black box of tricks is appealing!
Jesus guys dont talk utter bollox. The clue on the title is Ignition module. Nothing to do with fuel. The ignition module allows adjustment on the IGNITION not the fuel. The main use of the ignition module is to allow the quickshifter to work above 10000 revs as without it you cant use the PC3 shifter due to the secondary throttles taking over the main fuelling at around 10k. Ignition mapping is very specialised and should only be altered on a dyno with someone who knows what they are doing. If you want to control the secondary throttles using a PC3 you will need to plug in a second PC3 to the secondary throttles AND get a lot of dyno time with a good tuner. The sensible option is the PCV withe SFM (Secondary Fuel Module) (another clue in the name) or a Bazzaz system. Both control primary and secondary throttles. Both offer the option of plugging in an autotune device and both allow different target AFR so you can get a reasonable good map at very reasonable price and change it as and when you like. The downside is you cant see the effect in numbers on a power printout.
The secondary injectors are used for two reasons. Due to the speed of air entering the engine at high RPM. And get more fuel in. Years ago 1000cc road bikes hit 10 - 11 k area. Now they are hitting 13 and 14k rpm. The lower injectors cope well at lower revs but higher revs the air fuel squirt isnt atomised as well. Imagine when you out your perfume on. If you squirt it too close its a squirt. Further away its a mist. Thats why the secondaries are used and set much higher up. It allows the mixture to atomise better (mist) and therefore allows better combustion as well as allowing more fuel to be fed to the engine.
Mr OCD - how are you finding things now in the smoothness stakes with the PCV? I saw somewhere that you've now done the ECU reset too - did that help?
