gexgexgexgex Posted July 25, 2005 Share Posted July 25, 2005 my LOVES to run at 10.6 afr at idle, off idle at max power it is fine for right now between 11.5 and 12.0. i have changed the fuel on the VE table down to 1 at all the idle settings and it does not help. is this caused b/c i am running 450cc injectors. i have tryed my fuel presser from 15 all the was to 40 and it does not matter. i have a stock l28et engine just changed the ecu, to mega squirt and spark extra. any help would be nice. also does any one have the same injectors as i do and are using megasquirt and spark extra. because most of the maps i find are not for extra code.

Guest bastaad525 Posted July 25, 2005 Share Posted July 25, 2005 dunno how related this is, but thought I'd mention it. My bone stock L28ET with stock injectors and EFI seems to love to idle really rich as well. When I was tuning at the dyno, my air/fuel was at like high 12:1, and I thought that was too rich so I tried leaning it out, but as I did the idle started to get rough very rapidly. By mid 13:1 it seemed to really be struggling to stay running. Odd... I always thought idle was supposed to be at around stoich? Quote Link to comment Share on other sites More sharing options...
Phyxius Posted July 25, 2005 Share Posted July 25, 2005 my idle runs around 15:1 just fine... Quote Link to comment Share on other sites More sharing options...
mobythevan Posted July 25, 2005 Share Posted July 25, 2005 mine is around 13.5 at idle. I have 450cc injectors and I can lean it out however much I want at idle. Not sure what you are seeing Quote Link to comment Share on other sites More sharing options...
Afshin Posted July 27, 2005 Share Posted July 27, 2005 mine idles best at about13:1. idles poorly at 14:1 Quote Link to comment Share on other sites More sharing options...
mario_82_ZXT Posted July 27, 2005 Share Posted July 27, 2005 Are you using a WBO2 setup? If not, then don't look at those numbers, as they are way off. Mine likes it rich too, and it measures differently depending how I have ran the car or how warmed-up it is. Mario Quote Link to comment Share on other sites More sharing options...

TimZ Posted July 29, 2005 Share Posted July 29, 2005 Not sure what your current settings are, but you might consider running less timing at idle, and opening up your idle air bypass (throttle stop, needle valve, etc) to let more air in. Decreasing the initial timing will bring the idle speed down, opening up the bypass brings it back up and leans out the mixture in the process.
