Please help. I can't get my AFRs dial in correctly. I have 62mm Karman. Upgraded fuel injectors, pump, filter, reg. I have DCAI with xtreme filters. Can someone please tell me what to set my AEM regulatory gauge at. Right I'm at 60. AFRs are all over the board. Cruising range from 15.1-15.5. WOT is at 11.5. All these numbers are according to my AEM gauge which has a new sensor on it but is old. I don't know if the gauge is bad. I do have datalog I can share from Eurocharged program. Thanks.

 

Please research open loop and closed loop. In closed loop (cruising around town) your car will try to stay at stoich, which is 14.7. It should constantly bounce to just above and just below that amount. It won't just stay at 14.7.

Once you floor it and it goes into open loop, you should see 11's. Your 11.5 is good.

 

Thanks grip grip for help. I wish I could take a video of the gauge when driving but camera phone will not pick out lights the gauge. What do u recommend taking to dyno and mess with the pressure gauge there. I'm set at 60. Should I go higher or lower. I was told datalog from ob2 can't read AFRS

 

Do u know about datalogs. I could email you my logs and u can look at.
