The closer to the port, the less likely you'll have reversion pulses from other cylinders getting back up there and giving you erroneous readings. But, closer to the port you are exposing the sensor to more heat and shock, which may shorten its lifespan. Pick your poison. :)

I've heard it mentioned that big overlap cams in certain situations can cause false lean readings as well due to scavenging events, which is a pretty interesting theory. EGT's are great in tandem with the lambda sensor.... they can tell you quite accurately what your combustion/power looks like. :)

Have been planning to do this all year, but now that i've switched to MWR wsbk filter i think i will be getting a couple O2 bungs welded on atleast Cylinder 3 & 4 so i can tune it a little better using the race ecu software. Just need to see what cylinders are the easiest to get at as i can only map cylinder 1&4 together and 2&3, so don't think there's a need to put 4 holes in the exhaust.

I have 2 lambda sensors i can link into my datalogger to get some good ontrack info.

This is really great info

One might think the "stock" fueling have some compensation on 1-4 and 2-3 for the stock short and long stacks, and running all short may throw this somewhat off and contribute to a difference between the pairs, but I`m just thinking out loud.
Have you done similar individual measurements with stock stacks setup?

I`m just in for the ride

Nice work.

We picked up huge gains on a 2012 recently done before the race season. Testing/tuning methodology was the same as yours - nothing crazy used, simply the WRT software tuning per cylinder, dyno and lots of time to create individual maps for each cylinder.

From his last tune (combined AFR across all four) it put down a typical and respectable 184-185 to the wheel. After observing, tinkering and finally getting down to business tuning per cylinder, he picked up 10 extra horses putting him in the mid 190s. All on pump gas mind you. We then did another tune for him, this time on race gas and yeah, bike is a monster. We had great results doing this on a ZX-6R as well.

Tuning per cylinder is something that is often overlooked because of the cost since we have to make pretty much four complete maps for each individual cylinder. But for race purposes where the difference between standing on the podium and off of it are a fraction of a second and any advantage you can get makes it worth the extra cost. Good job.

Actually all race ECUs can be tuned just like the stock ones,not with the Kawasaki Fi tool,but with Woolich software it can be tuned just like a stock ECU.

I'd be interested to know what the air fuel is for each cylinder on a stock or near stock setup between a few bikes to get an idea if they are end up being similar from the factory. Like if cylinder number 2 is lean and cylinder 4 is rich compared to the others etc
