my 5sfte is running rich at idle. I have to take out 30% of fuel with my safc in order to get the 13-14.7 ish a/f ratio.
set up: 255 lph pump 440cc injectors everything else is stock What could be causing the problem???? could having the engine retared to much at idle be the cause of the ecu not being able to adjust to a rich mixture????? This post has been edited by urbandork: May 15, 2006 - 12:15 AM |

but anyways. do u think i should go with the 3sgte map sensor or new injectors. i know for a fact that the new injectors will help me run leaner. My experience with a 2 bar map sensor has given me doubts on it effectiveness of leaning a/f's. u wanna let me borrow yours manny? lol. j/k. but i really wanna see what happens if i put a 3sgte map on before i buy one for a $50-100 because i just bought a brand new msd 2 bar lol and it yeilded no effect. But again i dont even know if its wired in correctly?!  Anyways.. what do u guys think i should do? anyone live in washington that has a 3sgte map sensor?  someone that would let me plug their map sensor in for a sec? lol.. but kinda seirously. i'll drive somewhere. Thanks.

Thanks. DAn You should not "tune" by changing injector sizes. If you are running rich, you need to lean out the a/f ratio some other way, i.e. ems or piggy back. -------------------- QUOTE(lagos @ Jul 10, 2006 - 1:55 PM) [snapback]454118[/snapback] i know your trying to do the right thing for your motor, but this is one of those times where you should just trust the guys who have had their swaps for a while and have done a ton of research into this. |
