as the title says im curious to know what the correct afr is during anti-lag? i have searched but no results. idle is at 13.5/1 under boost is 11.5/1. i just want to make sure im not gonna mess anything.afr goes to 20/1 during anti-lag and it doesnt seem right to me so i have halted on that until i can get more info on this. should it read higher or lower due to the fact that its burning the fuel in the mani instead of the combustion chamber? thanks for any help guys.

I'm guessing this is combined with a 2step rev limiter? If so, the misfiring causes the WB to read VERY lean, usually pegging the gauge to the highest it will read. Just make sure your car is tuned well around this area during normal use, and ignore the wideband during the antilag/2step.

 

well antilag usually retards ignition a lot which in reality; timing doesnt affect afr all that much. but i dont think that youll see a constant number on the gauge anywho. depends on the program too.

oh and if your idle is 13.5 thats a little on the rich side. i idle at 15-15.5 or so.

 

thanks guys. thats what i was wondering. im running neptune tuned by servion. injectors are precision 1600s and want to ditch them and the aem driver and get a set of the injector dynamic 1000s. its on c-16 and when i switch injectors im gonna go e85, i just cant spend 14 dollars a gallon anymore.

 

ha thats my setup. ive got the id 1000's and e85. injectors are pretty gangster. and yea e85 is cheap. paid like 2.09 last time in my area. lol.

 

I know its off topic, but I just filled up the other day for $1.94. You can't go wrong with E85. Even with the reduction in gas mileage compared to Premium, it still costs less money per mile with E85

 

13.5:1 @idle isnt that bad especially for 1600 cc's. id bet that idle would get choppy if you went much leaner. my 880s didnt idle as smoothly at 14.5:1 as they do at 13.5:1.


also when i used to have antilag set up (neptune rtp for management) my wideband would also read lean.
