Bikes, Hints'n'Tips > Fazer 1000/FZ1 corner
Gen 2 mods??
Penguin-dog:
So I now own an 06 FZ1. Yay me!! Now as far as I am aware, and will soon get time to delve in amongst it all to confirm, the bike appears to be standard apart from a remus end can ( I believe cat removed)and black screen!!
Ive allready noticed the on/throttle snatch amongst a few other things.
But I am wondering weather the mods I've been reading about ie for the Air-box chopping and smaller butterfly valves etc. Are they all absolutly proven to help, as i have seen a few opinions to the contrary?? And can you do all or only some without the need for a power commander?
Tia.
Dudeofrude:
To be honest anything more than the exhaust change and you'll need to start looking at a power commander. Even then all it will do is ensure the air to fuel ratio is good and help smooth the power out a little.
As for the on/off throttle response, the only way to fix that is an ecu reflash. You have the 2006 model which has the famously jerky throttle response :-( they greatly improved it in the 2007 onwards models.
A reflash will set you back around £350 but from all accounts your bike will run perfect from then on.
You could try and find an Ivans fuel cut eliminator but again the reviews of them seem to vary.
If you do decide to go down the tuning route then obviously the more mods you do the better. So the lars airbox mod is great (and free), the secondary flies can be either removed or cable tied open (again free) and the decat (If not already done) can be drilled and smashed out.... for free
Race downpipes are about the costliest part and they aren't completely necessary but will add an extra few bhp
So not an expensive do and when you factor in the price of a power commander plus dyno runs then the ecu flash seems like a much better deal.

Why is this so expensive and why cant it be done with a laptop..? or failing that cant a 2007 ECU be sourced from the eBay / part-finder for less than that..?

It technically could be done with a laptop and the right software but you'd be stabbing in the dark without the dyno runs to give you the right feedback. It'd be like doing a custom power commander map yourself.... but a lot more dangerous for the bike.
It's more than just fixing the on/off fuel problem; the ecu controls everything so you can find tune every aspect of the bikes running.
Remove gear limiters, fine tune fuelling (without a pc3 or pc5), advance the timing, lower the fan temp etc
There's a lot to it and it's done wrong it can completely destroy your engine.
As for fitting a later ecu, a few people fitted the 2010 as that apparently has the best Yamaha map on it; I think it doesn't help the fuel problem but not as much as a custom flash would.
I also don't know how it works with regard to the immobilizer etc because I may be wrong but I think your key is coded to the ecu?

where would the gains be if you just drilled and smashed the cat out ?
