MSD 2 bar map sensor., leaner a/f's? Options

[penguininatux]

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.

Innovate wideband btw.

Oh and for Manny (pressure2) if you're lookin at this. or someone else with a similar to setup as us, if you could remove the 2 bar while idling (just the plug) and see if you're a/fs get really rich. that would help to determine if the 2 bar map actually makes a difference in A/F's

Thanks again to anyone who has the time to help!

i dont have a wideband.
i only tune on the dyno.

What sensor number are you useing on your safc for the input and output. Since you changed to the 2 bar.

[presure2]

nate, you should be using 1 in 1 out.

I have a 7afe and ive been running 3 in and 3 out. Ran it like this before i did anything to the car and it worked fine. Should i just stay 3 in with a gm or msd 2 bar?

[penguininatux]

sensor 1 in 1 out. like pressure said. and still pressure. even if you didnt use a wideband its still the same readings. I know im running rich. now tell me why !! I think im going with the 360 injectors.. unless someone knows whats up with my setup.

you will be rich down low, under 3000rpm, theres just no getting away frmo that.
you should easily be able to tune it to 11:1 or so with the SAFC after 3000rpm.

something isnt right with the setup. i'd tune to 11:1 if i could. It drops to 9:1 and below if i give any throttle and almsot dies. Does anyone know the pinout on the 5sfe map sensor.

Thanks.

oh and pressure. u have the 360cc's u used to use?

i never used 360s.
i started with 315cc injectors.

again dude, the only thing i can think of is that the fuel injectors you are using are faulty. get new injectors pronto.

[penguininatux]

what a/fs do u get at idle manny? with the 460cc's and u said like -10% correction. that doesnt make sense that i have the same injectors and even at -50% are running too rich to even drive.
