2015 air box mod / ivans flash

So I am thinking I am going to pull my ECM this weekend to send it to Ivan. While I do this I was thinking of doing an air box mod and new filter since he asks on his order sheet, figure its a good time to do it. Unfortunately I haven't ever looked at the air box or filter, or the ECM. So I am looking for a little assistance on ECM removal for one. For two what exactly is the air box mod people are doing on the 4th gens, anyone here done one and had good results? It's kinda hard to find a definitive answer, seems some just drill holes but I can't see where, little lost on this one. I am seeing BMC is a good air filter over a K&N anyone had experience with this? If its a huge pain in the *** I won't touch the air filter or box but if it's pretty simple and has good results I'll bite.

Talk to Ivan, I think he'll send you instructions for all of that.

Ivan does send instructions. If you would like to see a pic of what the airbox looks like after mod I have one posted in my build thread.

The 2016 Z1000 Project

It is the pic of me holding the black airbox. You can see 3 (I think 7/8") holes drilled on either side.

Thanks bear, If its just a couple drilled holes and no shaving of baffles or something then its pretty simple so why not.

I did mine as well. I think the gains are int he ecu, not sure how much the airbox mod really helps.

Well... At its most basic if it's getting more air in... Then he's got to put more fuel in...

I did mine because of the ecu reflash.

I dotnt knwo if its as big of a deal with the newer machines, but on our 2010-2013 bikes, the ecu reflash turned it into a new bike.

With that being said, if Ivan had to ld me I needed to paint the tank pink, I would have have done so. He knows the bike so well that following his specific instructions is not going to lead you down the wrong path.

I left my box stock and just went with the K&N air filter. I seen a comparison of a few air filters, and they all seemed pretty close to giving the same performance. I was able to get the K&N for $45 vs like the $80 or $90 for BCM? I'm yet to install it or the block off plates, but I imagine it will be just fine. To get to the airfilter, you gotta remove the gas tank and the airbox will be right there. Remove i think 6ish screws and the top comes off and you got the air filter in direct sight.

Well I still have the O2s I assume it is functional and that is where the ECU gets its readings to make the necessary fuel adjustments just like a car when putting in a Cold air intake, they can adjust themselves up to a certain point. I imagine the map is more of a setting it up to get the right a/f ratio at the right rpms. I could be wrong I never messed with bikes with computers.
