ksbkrew Posted July 27, 2008 Share Posted July 27, 2008 Hello can anyone give me the A/F ratio that I need to have with a BPU car at 1.1 or 1.2b? I need the ratio that is safe for my car! (uk spec) Thank you Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted July 27, 2008 Share Posted July 27, 2008 If you have no means of adjusting the AFR, ie piggyback ECU etc, then you will see AFRs of anything from 9.8 to 10.8, but the ideal is around 11.2. Quote Link to comment Share on other sites More sharing options...
ksbkrew Posted July 27, 2008 Author Share Posted July 27, 2008 ok so around 11.2 is a good value with 1.2b, no big risks of breaking an engine? Quote Link to comment Share on other sites More sharing options...
