bogging under boost? Crap!
 

I just became the owner of a sweet 90 miata. For the first few months it would run just fine. Then after a while it would buck occasionally right before i got into boost. Then gradually it would buck more and more before entering boost. But now it would bog and misfire when entering boost. But if im not in boost it would run just fine. I dont know what the heck is going on or what to do about it. Since I didnt do any of the mods or installs I have very little idea how the system works. So if theres anyone out there that has run into this problem. Please help!!

The setup: NA, manual trans, 1.6L, greddy turbo, Intercooler, BOV, eManage blue with autotune.

It also has a zeitronix wideband meter that doesnt work right. When i start the car it reads 14.7 then gradually goes all the way to 21max.

There you go.

Unless your eManage is autotuning from another O2 sensor, then you've got to get this one working.
