MSD 2 Bar Map Sensor Running Wayy too Rich
 

first off.

92 celica 5sfe 2.2 turbo
stock fuel injectors 213cc and upgraded to 460cc

Alright, i talked to a few people about this subject of using an msd 2 bar map sensor. My problem was that i was just gettin wayy rich readings at idle and during acceleration ( too rich to even drive), with my new 460cc's being controlled by an SAFC II. Anyways, i heard from a few people that using a 2 bar would help lean out my a/f's throughout idle and all rpms. So i installed it today. Seems like nothing has changed. I tried wirinig it in differently with no change again.


First off does anyone know the wiring of of a stock 5sfe map sensor, and then one for the 2 bar MSD pt#2312?

( just so i know i wired it in correctly)

And secondly. Why arent my a/f's dropping after installing the 2 bar? should they be?

feeback is greatly appreciated (seriously)

Thanks

Dan.

monitoring a/fs with logworks program and Innovate wideband btw.

You can't just run a 2 bar map on an ECU that isn't for that application or isn't reprogrammed.

hmm. well burien toyota 5sfe kit includes it with a non modded ecu. and everyone on toyota nation and 6gc.net are running it. And it kinda makes sense, because the safc intercepts the signal before it hits the ecu anyways. But whatever, im still running hella rich and i dont think the 2 bar map install helped. anyone have ideas?

thinkin about just going 360cc injectrs.


But the thing is, a guy on 6gc.net with the same engine and exact engine management and injectors runs the 460's fine. sigh

iono

let me know if you have thoughts.

Are the stock injectors saturated or peak and hold? What type is the new ones?

Re: MSD 2 Bar Map Sensor Running Wayy too Rich
 

Wow, MAP sensor swap is going to jack timing around a lot. KS equipped engine? That might reel things in enough to be runnable but not at all ideal.

How much fuel are you taking out with your AFC?

run rich at 0 correction. about 13.2-13.7 ish. and when i try to even drop to -1% correction it idles wierd as hell. like goes from 1500-2000 in less than a second and keeps repeating. anyways let me know


im gonna check the ecu wiring diagrams again.

Thanks.
