Hello folks , wasnt sure where to post this so any moderator can move it if i've made it in the wrong section.
I'm currently running a Wizard of Nos nitrous system (UK brand) and I also have a FJO racing controll unit named Maximxer , the controll unit is awesome and i love the extra safety it provides but i've ran into a problem I've set the lowest AFR to 0.6 volt before the unit cuts the nitrous and fuel and this hasnt been a problem earlier cause i've only fired the nitrous on 5'th gear and on 3500+ rpm.
After a couple of runs i decided to see how it would run on 3'rd anf 4'th gear but then unit just keept shutting down as soon as I hit full throttle.
I decided to buy a narrowband AFR guage from autometer so see what was happening while driving and injecting the nitrous , and it looks like a chrismas tree while accelerating going from lean to rich a couple of times each second
It's only stable when the ecu hits the closed loop setting.
So my question is is there anyway to alter or change the singal comming from the lamda to maybe give me an avarage value or do i need something else? cause right now I cant use the nitrous untill the system hits the closed loop.
Any advice or input would be much appriciated.
