Oh the ....
I feel your pain as here even lowering springs are a pita
to make legal.. But I always appreciated the overthe pond freedomyou had.
ME should be reseting the reflash counter and make no "trace" on the ECU..
I understand about the maskings, but the checksums.. How can they know what checksum is original?? Every HW version of the ecu and every sw version will have adiferent one.. That is just for the RX-8 upwards of 100 of them.
Each time an ECU is written to the ChSum has to be correct or thr ECU will refuse the code (unless the ME or Versa can bypass checksum test)
Anyhow wishing you luck

For conversational sake, lets say over the 8 years we got the Rx8 in the United States ('04 - '11 model years), that we got 64 "original" checksums (could be less, could be more. Just using for example purposes)
That would average to 8 checksums per model year. Remember that California has its own emissions restrictions separate from the other 49 states. So 4 were California and 4 were the other 49 states.
Now factor that each year we had the automatic and manual transmission options, meaning that 6 becomes 2 checksums for auto and 2 checksums for manual.
So for my 2005 model, manual transmission, the CARB will be checking my PCM for a value in one of its checksum's to be one of only TWO numbers... considering that even the smallest change can create a different checksum, that doesn't leave really any room for variances from the factory PCM programming. Heck, when ME dumps the PCM at first setup before flashing that PCM dump right back into it, just the fact that it did stuff to be able to get access into the PCM could result in checksums that CARB is looking for being effected, even if a non-emissions related adjustment was made. CARB is going after tunes, and they are generalizing to be just about any thing that has been changed.

Not a big deal, sometimes the car will sit for weeks until I get the time or motivation to wrench on it. I enjoy working on it....to a point, at this time though I have definitely spent far more time underneath it than driving it by a vast margin. I've purchased Brettus' manifold and will be going down the same path as you, and am fairly local, so was curious as to what progress was made, and whom you'd be using to fabricate piping.

That's ambitious, I hope it works out. Glad the emissions visit worked out, so glad I don't have to get my car checked here.

So in my case yes, the car DID pass the CARB emissions test. Car had a MAZDASPEED intake with the CARB sticker attached to it to meet requirements. Coils were stock, OEM cat converter and OEM header as well. So our cars will pass in California if you just flash the car back to the original ecu dump that mazdaedit creates and you have the required emissions components installed to the car as required by California law.

also meant to suggest this controller setup to you a while back; it’s specifically designed for NA cars converted to FI that still use the factory non-FI ecu
