Hey guys I know I'm new to this forum so if I'm out of line please let me know. My name is mike I'm from huntsville al, live in va and in the navy. I'm 24 years old and have owned 3 rbs one r32 and drive nothing but Nissan s since I was 17. I have read this forum many times and decided to join for the sake you guys have your stuff together.I have searched this forum for my problem but couldnt find an exact solution. Hope you guys can help. I have a s13 stock neo 6 that has a huge ecu timing retardation problem. i tryed the knock sensor one mohm trick , didnt work. Hard timing is dead on cleaned the maf, plugs are gapped exact (32). Ngk laser platnium. the reason i know ecu .is pulling timing is when i advance the timing maxed out on the cas (counter clockwise) she runs better . When i set it to factory position(had it marked) it spits and spuuters wot. If i ease on the gas itll spitt a little bit ( 4 or 5) times . But will go to redline. Now, i had an extra cas that i cut the adjustment holes out so i could advance the timining beyond the factory settings. And it runs great, no sputter........ So thats why i concluded the ecu is retarding my timing. any ideas ? This is my 3rd rb and ive never seen this before. Thanks for all the help.
