Nothing like that on the maps I have ..............screen shot it.
You are overthinking the process IMO.

Circled in blue. This is on my stock unmodified map.

I was more or less curious if someone knew the reasoning behind this section of the fuel map as it stuck out to me.

Interesting .... that lean spot isn't on JDM tunes . But I see it on the US and EU maps

Right? Perhaps it was for emissions reasons/numbers.

Alright well I have been playing around a bit more. I tried a similar map to what Brettus had previously posted, except I followed Kane's advice to lean out to 12.1afr. This actually made a huge difference in how smooth first and second gear was. The car was much less jerky.

Otherwise I have gotten within 3% of my afrs across all the ranges. For the Higher RPM ranges it is very beneficial to do multiple tuning runs and adjustments on the same day and on the same flat road.

I had some trouble for a while where I had a linear error in the second injector band. Then the error was about halved in the tertiary injector band. In the end I had reduced the secondary+tertiary injector scaling from 475.93 by 8.2% to 436.96. This leaves me running 0-3% rich instead of 5-8% lean at high rpm

Something that may be screwing with me in the top end is that I had opened up the APV ports slightly and port matched the valves. I played with the VE map to test a few things and bumping up the higher rpm section after 6250rpm(APV opens) appears to have had a positive effect afr error wise. I remember a few threads/people saying to avoid touching the VE map though, I will look around again for why.

I am actually going to work through my Clean black body Rx8. Already have mazdaedit setup for it. Perhaps I should have gotten versatune to be able to compare, but I already had the dongle setup for mazdaedit. Inevitably though I will be looking to have a rew block built and begin a swap thread. Its renesis would likely be kept as a backup engine for the Red rx8, or perhaps rebuilt for a turbo renesis.

Other than tuning as I was looking into the gauge cluster issues earlier in the thread I came across something interesting.

It appears these guys are creating an aftermarket gauge that fits the Rx8. Not sure, but they may be marketing towards LS swappers, although there may be a good market for all Rx8 owners. I sent a message asking about a few things like including an oil temp gauge instead of battery voltage, and changing the color scheme to red for night vision benefits/matching the rx8 red dash.
This may solve issues like:

1. Aftermarket gauge clutter on dash
2. the Rx8 dummy oil pressure and coolant temp gauges
3. the inaccurate by design tachometer (Rx8 tach reads high by 500rpm when the engine is at 8500rpm displaying as 9000rpm on the stock tach)
4. The lack of an oil temp gauge

I will be keeping an eye and see what they respond back with. Perhaps I will end up making a thread for it.
