ECU Flashing

So I’m getting a slip on and k&n air filter this weekend installed in my 2019 ZX6r. I already have a FTECU tuner on it running the unrestricted tune. Question is how do I tune it for the new exhaust and filter? I don’t think it will be 100% necessary to have a tune but I think it will run a little lean and I want to smooth it all out. Do any of you know of a map I can just download and install or do I have to sit there and play with it and basically make my own map? Any help would be great.

Hello j.bird4

The best option it to get a wideband lambda and make some measurements during WOT pull and some mid range throttle in and out actions. Basing on those AFR result, it should not be a tricky thing to adjust your map. I would strongly recommend not to use "ready tuned map" - in most cases they're quite crappy.

I have never hear of a wideband lamda. I’ll have to google that one. But that you for the info.

Ok I just googled it. I see it’s a gauge. So does it go in place of the O2 sensor? Do I ride with it on? Again I’ll have to google how to use it but your seem knowledgeable. Thanks again.

I forgot when you talk about Woolich what product are you referring to? I was just thinking of getting something like this.

I didn’t see anything like that on woolich website. Tell me again if this is the wrong product. Sorry to keep asking so many questions. I know tuning can be as simple or as hard as you make it. I’m just trying to learn the basics.

That would work too. log-box-mitsubishi-zeitronix-zt-3-wideband-package.you plug in a laptop to read the data.

Hi. They run extra rich anyway to compensate for when people add filters and exhaust and so they dont go pop when you try push that little motor to 300kph. Unless a full race motor has been built only really the timing needs to be adjusted as the ecu reads a/f ratios and adjust accordingly within its range.
