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.

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?

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.

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.
