What is this o2 issue you speak of? Also has Charlie disabled the postcat o2 sensor so that if I were running a decat the ce light won't come on?
The tune currently in the ECU is for a stock '07 Exige S. If you run a decat, or headers, or smaller pulley, or something radically non-stock, CharlieX will have to tweak things for you and you need to work that out with him.
The issue I was having was that the O2 sensors on the emissions check would not clear. I ended up replacing both of the O2 sensors at about the same time I got the new stock ECU. Everything cleared out and the issue went away so
what the problem was. I'm just happy to be driving the car again.
The o2 sensors issue may have been related to an aftermarket exhaust in which the main tube broke internally and all the glass pack stuffing plugged up the system. With restricted exhaust flow out, the sensors may have gotten loaded up / killed off. Again,
After fixing the exhaust, and resetting the CEL the O2 sensors would not clear. The car ran with no problems until I spun a bearing while on track. At that point I retired the car from track duty but have kept it as a Friday driver.
I'm trying to be upfront about what I know and what I don't know. All of the above is chronicled in painful detail in the Engine Forums over the past 12-16 months. Run a search or flip through and look for my posts.
Bottom line, the tune and the ECU will run a stock '07 Exige S just fine.
I am selling the ECU and tune because now that I have the car in drivable condition and it will pass emissions, I don't want to f- with it. I have a turbo Miata to fling about the track with wild abandon and I can walk away from that car with it burning to the ground and be out way less $$$ than my Lotus.
If you are local to Houston, TX and want to try before you buy, send me a PM as we can make arrangements to make it happen.
