Tunes for K&Ns + Reband

[Pedro]

you have connected as per instructions, crank sensor ,earth to battery , you can read tune in ecu. you can do test etc.fan. fuel pump etc.

Yes, I have it connected as per the instructions, I've done the tests, seems fine.
1 thing I noticed was that there is now a delay between the sweep of the tacho and the fuel pump activation (I think it's the fuel pump). If I remember right they both happened at the same time when turning on the ignition. Now it's 5 seconds or so.
I can read the map with TuneECU no problem.

I have a car battery hooked up to the battery terminals, 11.7v. It does not drop when the start button is pressed and it goes click...

Pulling whats left of my hair out..

That 5 sec delay doesn't seem to happen all the time, now it's back to being at the same time.

I would disconnect the PCV to chech the tune. And back track all your connections.
And reconnect and try again

Woo hoo... I did this for the second time. Looks like the Crank sensor connector has a bad connection, Taped it up and all is good.. Looks like the CBF is staying at home this weekend. Now all I have to do is find all the nuts and bolts.
Thanks for all the help lads.

well done Haggis! I look forward to admiring your handy work on Sat. Be good to see how runs against a stocker

Thanks mate. Doesn't look so hot at the moment, tomorrow I'll be doing the bearclaw chop. also the metal cover for the pillion foot rest thingy doesnt fit now that I've fitted the Reband. I'll need to cut that down a bit too.

I'll have to take it for a ride tomorrow and see how the tune holds up.

Good work mate

Now that the bike is running I've been thinking about the TuneECU and PCV setup. Please correct me if I'm wrong.

1. TuneECU hex map - Reprograms the fuel/air ratios plus other bits and bobs, for a given configuration. In my case these should be optimised for Exhaust and filters.

2. PCV reinterprets the TuneECU programmed instructions from the signals from the module and these instructions are sent to the injectors.

It seems that there is some doubling up going on. Should I be using 1 of these options instead of both? I received a tune from Hanso which I would like to use rather than have it superseded by a one-size-fits-all PCV tune.

Correct but it is tune done one another bike in possibly different conditions so it is a close to your needs safe tune
2. PCV reinterprets the TuneECU programmed instructions from the signals from the module and these instructions are sent to the injectors.
correct but it needs to be set up on a dyno to make it accurate unless you use a Auto Tune which will trim the TuneECU tune's fueling up or down to suit your bike

So no it is not doubling up if done correctly, either get it dynoed or get an Auto Tune and either create your own or use my AFR map

The power commander snatches the signals sent to the injectors by the stock ECU and modifies them, it will not and does not change the stock system. Tuneboy and tune ecu are a reflash tool, which re-write the stock ECU. The tune Mitzy had put in by Fred is from the same set up on another bike, which I sent to Fred to use as a base.This was to save him time, a) because he is doing it for bugger all due to the make a wish foundation link. b) because he is a friend of mine and we help each other... Auto tune is useful , but has it's shortcomings. I am not going into that here. I can put a tune from one bike to another, with all the same mods and the bike will run ok, mostly. I guess around 92-95 % , if I retune that same bike it will run perfectly. A tune dragged from one bike to another is never spot on. Some people don't care or even know. You know the guy who you are reluctant to lend your mower to? We all have a friend like that, he can stuff anything you lend him, he will say," yeah mate do this , my bike runs great!! " In the quest to save money many bikes do not run all that well. I ( and I am sure some others) make a reasonable proportion of my living fixing "cheap dynotunes" and home tune efforts. All I am suggesting by this post is that you guys need to be careful your $25000 motorcycle is not compromised in the processes you are using. All bikes differ a little in the engine, as well as the many electrical sensors and components feeding input to the ECU, these differences make an individual thing of the machine. Have fun guys
