Already done that test to some extent ...... two days of pretty much constant driving around . Fuel trim at end of that was close to zero ... so ...............the tune will hold .

What you are referring to is no different to the S1 . It took us S1 guys a while to figure it out as well .... BTW

The S2 ECU is able to self-learn and modify some values, so wanted to see if Brettus was aware of that or not.

It's happened to my friend's S2 during the turbo project with Mazdaedit editing the maps.

Not sure if the S1 ECU will do the same as I have no experience with it.

My S2 is fully tuned and all of my logs are now exactly as they have been 6+ months ago when we finalized my tune. From the MAF scale to the trims to the AFRs that I experienced on day 1.

I'd love to see more information about how minus the fuel trims which are stored in volatile memory, the ECU has modifiable persistent storage to hold dynamically calculated maps. That is what you are implying

Let me ask you again, 9k, what's more important to you, having a bigger e-peen than me or finding out more info regarding S2 turbos?

Same here. I know a bit about this project being thrown around.

One key point that has been missed. It is the shops first attempt at MAF / flash tuning.

I respect the tuner and believe he'll make the transition, eventually. That S2 was well over 200 pulls last I checked in on it.

There was also the matter of a thunderstorm and major power surge mid flash that hasn't been mentioned.

Kane offered assistance at one point (indirectly) but I'm not sure if that ever actually happened.

I hate to bump up this thread, but while searching for a different part on t3h Googles (I need a new AUX port ), I stumbled across this: Turblown Top Mount Rx-8 Turbo System - Turblown Engineering

Towards the bottom:

2009+ S2 Rx-8s require a more complicated ECU which currently requires wiring into the OEM harness. It does retain all OEM functions( No check engine lights, fully functioning dash, etc). Two ID2000 secondary injectors are also recommended.
I don't know if I'd want to gamble that much on something that isn't proven. Plus, I've read some bad things mentioned about this company in the past, and I don't know if the negative stuff still applies today, so I was hoping some of you might chime in on this.

There are better tunining options now, mazda edit and one other I can't recall at the moment (I believe Paimon has the other one) so there is no need to wire anything into anything else. I can't say much about the kit as I don't have one.

There are better tuning options and any of the S1 kits can be made to work on an S2, someone just has to take the plunge. Turblown is and always be shady and the product they ship out is sub par, the same people are running it. My buddy with a year old Turblown top mount kit has a cracked manifold and his local fabricator (found after his fiasco of buying the kit from Turdblown) told him it would crack when he saw it a year ago.

Thanks.

I have a buddy that actually customizes turbo kits at his own shop. He's worked on RX-7s before, but never RX-8s.

I might have to have a talk with him, since the S2 ECM isn't a bank vault anymore.

Yeah the manifold is the hardest part. You can run a Greddy kit or buy a PTP (stout performance now) kit. Those would be the two that I would pick since the fitment and customization would be minimal. The main fitment issue will the with the S2 oil pan setup and the turbo manifold.
