I'm on my 3rd set of O2s in 1000km now since I installed the Saleen Series VI and JDM tune. Anybody have some suggestions as to what would cause this? I assume my EGT's are waaay too high, but the dyno doesn't show me leaning out or venturing into dangerous territory. I have an Innovate Wideband and cooked that one too. Also now on the 2nd sensor. I bought a heat sink to go with the second one. The first set of 02's I figured were cooked since I had 50k on them, but then 2nd set barely lasted another 1000k which was a mix of street driving and about 100k on the track. JDM suggested I check the trim. Haven't done that yet....any ideas?
