i have recently been trying to get my car back on the road and having been setting the tune with nistune. i have my idle set great and it will idle all day at 14.4 where i set it. now i am having the ecu target 11:1 at WOT on the fuel map with a smooth transition all the way up. problem is when i get into a cruise situation the car will sweep from 10:1 to 14.7ish:1 staying at the rich side way longer. it will get leaner if i give it a bit of gas maybe up to the low 12's. also when i go WOT it will go down to 11:1 then go up to 13.7:1 at WOT!!! i let off there i didnt want it to get any higher that was bad enough. no matter how much correction i make i cant get the ECU to compensate for these 2 problems. maybe my VQ map is set up wrong, or maybe my o2 sensor is causing this? i have 4000 mile rebuilt motor stock rods forged pistons tomei mls headgasket, FMIC, tubular bottom mount mani, 2860rs .64ar, 800cc deatschwerks, nismo fpr set to stock pressure, isis blast pipes, and nistune with the tuner license. maybe you gusy have some insight on this?!?!?!? i am new to tuning and my buddy who is very competent on rom raider with subies is helping me. any constructive thoughts?
