Hi adam. thanks for the quick reply. will heed your advice and look for another wideband. quick question though , this wideband / narrowband thing , can the car run safe withouth it ? ..i mean granted the shop really tuned this since they have target lambda table...i mean how does the ecu calculate fuel ...are there other sensors it will base it from ? sorry noob question since all my cars have lambda readings. thanks. again

Hi i have no tuning knowledge so i'm attaching the tune file the shop has on my car , hoping any expert here can check if they have the parameters correct. I'm using a monsoon ecu. 1jz vvti / gt35 single on 12 psi. / 760cc injectors / Tial wastegate set 1 bar / headers / 3 inch straight pipe / stock ignition coils on bkre7 ..producing 350whp. the car idles / runs smoothly , as it has been dyno-tuned ( i wasnt present but i have the runfile pics. ). my concern is that the wideband AFR attached now to my car is reading 12.5 idle / cruising ...10.9 WOT ...but shop told me it really is 14.7 with the dyno egt sniffer and my wideband is not reading right. is there a way to check if everything is ok with the attached tune file ? ..thank you so much. eb1.pclr
