Title: Lambda jump at idle 1.8t Post by: JeanAwt on August 30, 2024, 08:40:01 AM hi, I have the lambda value which jumps from 0.99 to 1 and the idle also at the same time. if I stay at idle for a long time it stabilizes at 1 then it starts again. I have 550cc injectors at 4bar ev14 0280158117. What variable should I save? should I correct my tvub or correct it in fkkvs? where should I start? of course no air leaks and joints ok.Thanks
Title: Re: Lambda jump at idle 1.8t Post by: JeanAwt on September 01, 2024, 12:11:11 AM no answers... so something is wrong with my question? so I will start by seeing if the ecu is trying to enrich or deplete
at this time... update it had nothing to do with fuel. I redid everything iop/irl, zwop and reflect the axes. put back stock the ufil/uof limitations. and now it runs wonderfully. I redid zwop with the wizard converter so since my axes changed I probably had a timing problem with zwop stock. I'm slowly learning from my mistakes... I like this forum for that if my questions are stupid...no answers and that forces me to read and search |
