Using the Woolich Racing LogBox M v3 kit, I finally finished dialling in the AutoTune on my ZX-14R with the Yoshimura R-77 4-1 full system. To get it perfect, I had a professional shop laser-weld a new bung into the exhaust for the Wideband O2 sensor. It cost a few extra bucks, but the result is absolutely worth it.

The process does require some patience to learn the software functions, and you’ll need to put in some miles on the road to log the data if you don't have access to a dyno, but the end result is excellent. The engine feels much stronger with instant, punchy acceleration, runs cooler, and is silky smooth at low RPMs. The Woolich Racing system is truly top-tier!

The target AFR table is mystery #1. How did you choose your AFR numbers? Mystery #2 is an even bigger mystery: timing. Did you mess with timing at all?

Thanks, Rook.
For the target AFR table, I didn't start from scratch. I used a solid baseline map and adjusted the targets based on standard safe zones for the ZX-14R with a full exhaust. For the cruising and low-load areas (the vacuum columns on the left), I aimed for around 13.2 to 13.5 to keep it smooth and efficient. For high-load and Wide Open Throttle (WOT), I went with a safer, richer target of 12.8 to 13.0 to maximize power from the Yoshimura 4-1 while keeping engine temps under control.
As for timing—no, I haven't touched the ignition maps at all. The stock timing on these bikes is already quite advanced, and since AutoTune is purely for fueling, I wanted to get the AFR completely dialed in first. Fixing the fueling alone completely transformed how the bike pulls, so I didn't see a need to mess with timing for street use.

When I road tuned my Gen1 with Dynojet equipment, I went with 13 AFR throughout the entire table...mostly because I didn't know what else to do. I was told I would get a little better torque by tuning rich and best hp tuning lean. I had a map with various AFRs. I used that as my base map and just filled the target AFR table with 13. I didn't feel a day and night change from the base map as far as power was concerned. I did get the bike to accelerate smoothly at WOT from 2000 rpm in 6th gear. I just did that to see if it could be done and darned if it couldn't. The tuning also completely smoothed out the flies. There was an abrupt increase in power at 2500 rpm and again at 6000 rpm. My base map smoothed it out but the tuning eliminated it altogether.

I had (have) an ignition module on the bike too but never got around to messing with it. TREs were a popular mod for the Gen1. No timing restriction through locking the mapping to Neutral or 6th gear. IDK how much I'd play around with the timing beyond that. From what I understand, there is no readily available software that can be used to view the stock timing tables so tuning timing is all guesswork. I have a stock timing table for the Gen2 but who knows if it's authentic? If it is, how much would I play around with it?

I'm going with a flash first but after that, I'd like to try doing it myself again, this time with Woolich. Unfortunately, I won't be able to use my Moore flash as a base map. I was recently told by you or perhaps another member that if I open up the Woolly software on my Moore flash, that will wipe the whole ECU clean.
