I know the v.e debate goes on forever both ways on the l67 platform. I have had this car for about 4 years on e85 and have not really had a kr problem. last year i installed new stainless valves and fixed valve sealing problems and it pulls better than it ever has. my question is i sometimes get a randon kr spike under sudden throttle stabs. spike looks like a shark tooth so i question if its real or not. have we learned if the v.e table is totally useless at this point? the research i found suggest that some o.s do and some don't. for shits and giggles i tried to bump up the v.e table by 20 -30 % and failed the map and try to start the car but it wouldn't start or run unless the maf was controlling the fuel. i dont have a scan yet but can try to get one. i do notice it more when the a.c is on2001 monte carlo.l67 e85 new build daily #4 3 deg removed after base afr correction.hpt
