...that is, perhaps the WB02 sensor end in the exhaust isn't working, even though you replaced it once. Are you certain it is connected properly and the Link is set to WB02?

It may be that the link is responding to the input received from the WB02.

The story is long, but I will shorten it a bit. I had a 91 Miata that I built using the framework from a 95. A 95 engine and wiring harness. I installed a FM turbo kit and drove it for several years with no problem. That car was involved in an accident three years ago, and totaled. So I bought a 91 Mariner Blue (which I wanted for along time), and stripped that car down and rebuilt it from the ground up. I incorporated all of the stuff from the totaled car, plus more upgrades into the new 91 chassis. The only thing that was not the same was the wiring harness. The 95 harness in the totaled car was somewhat incomplete, and I had a complete harness from a 94, so I used that one instead. After 4 months of building the car, I had it finished. It started and ran pretty good, except for a oil leak that I had to correct. I took it out for a drive to work on some tuning, and it developed a problem with the WB02 sensor. For some reason, the autotune feature was removing fuel from the map until it went completely lean, and would stall. It would do this while idling or driving. The WB02 I have is a AME non-gauge type, so I borrowed a Gauge type from my son and hooked it up to read the exhaust gasses while the non-gauge was used with the ECU. The gauge type mirrored the readout on the keypad, and I assumed that the WB02 had gone bad. I purchased a new WB02, complete with controller, and installed it. At first it appeared to resolve the problem, but did not. The ECU kept removing fuel from the map. I then thought that something was wrong with the ECU. I had a problem with it a while back where something got burnt on the circuit board, and had it fixed by Flyin Miata. So I removed it, and there seemed to be a new problem with a capacitor on the board. I found a local shop to fix it for me, and re-installed it, but that did not change anything. The chip in it was not the latest chip, so for fun, I wrote FM and got them to burn me a new chip with the last software revision on it. That did not change anything. I was able to find a used Link for a 94-95, that was in good condition, with no repairs, and installed it in place of the one I had, that did not change anything. I then thought, well maybe it's the wiring harness, since that is really the only thing that was not used from the first car. But it is suppose to be the same as the early 95. I know that it is not "Exactly" the same, because I went over the complete harness before installing it and I could see some obvious differences in, but the the ECU, it should not have mattered. So I am not sure if I should go ahead and remove the 94 harness and re-install the 95 that I know worked? Can you think of something that I am overlooking? I am hoping that it is something simple that I just can't put my finger on. I was hoping that someone with your expertise may be able to see something that I cannot. Thank you for taking the time to read about my problem, and I hope you can shed some light on this perplexing problem.
