akyakapotter Posted July 1, 2012 Posted July 1, 2012 (edited) Ok so I've been having a play with my AFR's have a wide band and rrfpr so it's all good I can see what's going on my question is i cant get it anywhere near 10's on boost all I seem to be getting is some where in the 12's it's curently sent at about 3.5bar of pressure on the rrfpr cheers nick Edited July 2, 2012 by akyakapotter Quote
Johnboy GT Posted July 2, 2012 Posted July 2, 2012 Is that not about right? Cant remember what Sam and thats discussion consisted of not long ago though?John Quote
akyakapotter Posted July 2, 2012 Author Posted July 2, 2012 Im sure I read that people are running 14 on idle and about. 10 - 11 on boost mine won't budge from 12 it may if I wind it down a bit more but then I'll be pushing 5bar of fuel pressure lol Quote
Flaminsam Posted July 2, 2012 Posted July 2, 2012 Hey yea it was discussed quite a lot on the topic of afr. Most people came to the conclusion that on idle it should be near 14.7 and on wide open throttle 12.2 or less was ideal. Preferably around 11-10 afr. That's what was decided any who. After a lot of research its not only afr that a tuner looks at. Its exhaust gas temp, ignition timing and alsorts. Best stick to 11-10 on full boost/wide open throttle for now. Quote
akyakapotter Posted July 2, 2012 Author Posted July 2, 2012 That's the thing can't get it down that far Quote
Flaminsam Posted July 2, 2012 Posted July 2, 2012 Hmm what rate is your rrfpr? Is it 1:1 or 1:2? Quote
