noraa tan Posted July 19, 2019 Report Share Posted July 19, 2019 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 Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 20, 2019 Report Share Posted July 20, 2019 No one will be able to tell you much from a map alone. You will need to get another wideband on there that you trust. Quote Link to comment Share on other sites More sharing options...

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 Quote Link to comment Share on other sites More sharing options...
