My personal thoughts on the Adaptronic: I have been reading about it since 2012. It has its benefits and if there weren't other things I would like to spend that kind of money on then I would likely pick one up. But the AP has worked well for me so far and I would need it anyway for emissions, no? So... Plus it is one more layer on the onion that already makes me cry at times. I've got nothing against it by any means. Just no compelling reason in my situation at this time to drop the cash on one. But I am watching others experience with a touch of envy

Set closed loop exit to 500 rpm .... no more closed loop .
Not great for fuel economy but good for high load consistency . I ran mine like that for a few months but eventually decided i liked the fuel economy , plus if your system is good , it's not necessary.

Ok, I was waiting for some magic checkbox I hadn't discovered

I though you had a method to disable LTFT only vs disabling closed loop entirely.

It's a good strategy for tuning, easier than disconnecting the front O2 sensor

Agreed! Sorry if I gave the wrong impression. I've used the strategy myself. I just went down the rat hole of thinking there was a magic "Disable LTFT" option I had missed

re: Adaptronic

Yes, if they would incorporate the CEL defeat strategy it would then be the true RX8 solution IMO.

Update on the AR3932 plugs I installed back in January. I have been getting a few occasional misfires so I checked the plugs last night. They were pretty well worn so I replaced them. Much better They lasted 6 months running 10psi boost. Started out gapped at 0.025" and ended up worn to about 0.040". Not sure how many miles it has been, but unless there is bad weather this is my daily driver. At $3.99/ea I don't mind changing them a couple times a year.

Ya, that's what seems to have happened to the guy on the rx7 forum that I posted about awhile back in the spark plug thread:

https://www.rx8club.com/series-i-maj...2/#post4658452

I'm going to keep closer watch on this set...

Car is still running great. Always tinkering. I think the AR3932 plugs were too cold. Switched to NGK 5255 all around. Used an extra washer on the trailing (Team need not chime in ). Running 12psi now. Considering WI before I go any higher.

Couple of 2'nd gear graphs. I'd do 3'rd gear but afraid they'd get pulled down for street racing, JK!





Got a fairly deep scratch in my door so I'm learning to paint.

Nice numbers slash. I'll be back home in about 2 weeks to get my turbo rebuilt and hopefully everythign will be running right before I have to come back to work in 6 weeks. It'll be nice to bump it up above 6 psi.

After I popped the motor last year I promised myself 10psi max for awhile. Well, I've crossed back over that line. I figure it's only a matter of time at this point...

I have a hose from the LIM hooked up to a snorkel into my ears. Based on free diving experience I can tell how much pressure there is by my ears popping. Then I type really fast when I take logs.

Kidding I'm not logging boost. That boost graph is actually load. A trick Fazda showed me. You can pick any column for boost or AFR in VD.
