Yeah, I'm using (or trying to use) exactly what you described above. You do not have to use the O2 sensor they provide, but one additional wire will have to be hooked up. The instructions say that for best performance, to add thier o2 sensor in addition to the factory one. So I did. I had a bung put in the downpipe. So far, it's a piece of crap. My gauge bounces around constantly, from one extreme to the other, and the little red light is on constantly. Greddy's awesome instructions never address what a red light that stays constantly on means (not blinking, they address that).KReddy05 said:
Ryan23 said:I think Greddy probably sums it up best, " Do not use the Greddy A/F gauge for tuning!" It's right there in the manual. I had one in a previous car, it was not accurate and could not be calibrated to match my dyno's wideband consistently. The problem is that the sensor gets saturated very easy and with the narrow operating range it has, should not be used. Don't be too cheap when tuning your car. Cheap EGT, Boost, temp, fine. A/F, nope. There is a good reason that the Greddy unit is $250~$300 and an FJO (with display) will run you close to a grand.
