i have i believe 20 or more failed sensors on my dyno
many fail on full lean others fail on stoich other on full rich
with 15 dead on and not even moving at all probably the tinywb failed

Yeah, so pulled out the tiny, swapped in the narrow, configured it and it runs and shows mixture. Thank god i wired for both.

Another knowh problem confirmed - fuel pump is dying, i think ( intermitent lean spikes and running leaaan after warm up) ve map shoudnt be that fucked up, guess the pressure drops or i'm tuning on half of it. It shouldn't need 103 ve at 30kpa to barely get 15:1 at 14:7 target? Or 130ve at 4000 at atmo to barelly get 18:1 at a 12:5 target.

Fuel pump- swaped the dead one for e36 one (e36 and e46 1.6sohc to 3.2m3 had the same one 170kw capable). Hmmm lean spikes disappeared, what could have been the couse???

O2- wired some 3wire i had laying around- ok ecu is seeing something... Intermitently (was in an unknown state) aaaand it died. Bought a new bosch narrowband, wired that in, at last its tunable....ish, now needs some time put in.

Also anyone else experienced noisy vss? Even when parked signal is jumping sometimes just 0-20km sometimes 0-50km :/

Aaand i've been sold a dying o2 , should have guessed that someting is not right when i saw the box had been opened, and the sensor had way too much antiseize on the threads. Thank god for the return policy.

Wooo, 4 wire o2 works, datalogging is a god sent. Also used one of 1.6 miata tune from tune view as a base, better than not having anything at all, ignition maps were close. VE maps waay off, but the function of AFR and AFR Delta helpped alot.

Yay it has a base'ish map.

Hard start issue. Fouls plugs. fires every 4 th cycle during start if youre lucky starts....

Diagnosed it down to trigger pattern, dont know how it worked at all, but it did.

The problem is i defined the trigger as "miata" whitch is 4-2 wheels, mine is 4-1 (almost halfmoon).

Decoder coding gurus, would copy'ing the trigger pattern in the decoders.ino firmware before compiling and rename'ing it in defs to 323 4-1 and change'ing the angles in the def to match 4-1 be enough or other parts of the code rely on the 4-"2" part?

Or would it be dual wheel with primary wheel being 2?

I dunno about decoder coding gurus, but that looks like it might work with dual wheel.

Just rewatch'ed Decoder coding video for the second time made it all clear ish. Would love for the noisymime to chime in to clear up the filtering part of the code. I would love to just copy the mx5 part of the code and modify the angles for the single tooth. That video explains why it was such a hard start, it had only 180 out of 720 of chance and the filtering code might have been fucking up when it saw the secong tdc trigger couse the cam trigger is almost 180.

+1 to @jonbill, that distributor wheel is perfect for Dual Wheel set 2/1 at crank speed. Lots of engines running well on that simple setup, and no need to complicate things or write anything. :mrgreen: I did a Mazda 323 1.6 setup with that same distributor. Easy. Go for it!
