Miata Turbo Forum - Boost cars, acquire cats.

I have a '96 turbo Miata that has been spiking lean under load. The higher the load, the more it will pull fuel. Also the hotter the car gets, the less load it takes for the car to pull fuel/spike lean. The car is currently on MS2 running new RX-8 injectors. EGR is blocked off and charcoal canister removed. It also had the same problem when the car was completely stock, stock injectors/ECU/n/a etc. So it is most likely NOT injector/ECU related. This only happens when it is 90°+ outside and and driven somewhat spiritedly. Looking at the datalogs, I have yet to see anything weird going on with the MS, it seems to be doing what it should given the conditions it sees. Pulsewidth is matching MAP etc. Also, after analyzing a composite datalog, I have determined that both the crank and cam sensors are function properly. Any thoughts and help would be greatly appreciated.https://www.miataturbo.net/attachmen...ine=1467298713
