It works!
Always amazed

Thanks Lance and Matt for all of your help!

Received my MAP sensor today and I am ready to begin installation on the 3.57 board. I pulled up the 3.57 board schematic and did not find anything labeled Proto area.

How do I identify the proto area?

Thanks for your help

Thanks Lance!
I assumed the 3.0 instructions were close to correct for the 3.57 but did not find specific instruction as you provided...

I found this statement in the 3.57 information that appears to be relevant to this application
"The prototype area has not been implemented on the V3.57 board ...

I am running a 3.57 with V2.891, 4.3 vortec multiport, wideband 02, edis 6 in a 85 4runner that I take to the Rockies every year to run high mountain trails.
Can I install a MPX4250 Baro sensor and run realtime Baro correction on the 3.57 board ?
If so how is that done ?

Thanks for the help!

nice work. :yeah!:

i saw your original post when you found your manifold, and was hoping you would see this through. looks like a very nice install.

Thanks TM,
I went with the LC-1 wideband 02 as well so I think this swap is going to be sweet, Its not really even close to tuned and it already ...

I fired it up today. '98 4.3 vortec with a mercruiser multiport intake, edis 6 running the MSII 3.57 / v 2.8 with the relay box swapped into a '85 4runner.

My brain Hurts ...

Thanks Charles, thats very helpful information.
I am thinking an open IAT in the cold air intake stream makes sense, just from the nature of the design the advantage for rapid adjustment would be worthwhile.
I installed the VR sensor and had an early visit from Santa today!

I got my harmonic balancer with the universal 7 1/4" trigger wheel back from the local machine shop yesterday. Very good work its almost "press fit" tight, but can be worked on by hand. I am thinking of using some loctite sleeve retainer #640 to hold it in place.
BTW, the machinist is megasquirting ...

:roll:
This is the bosch sensor - combination map and iat with 4 pin terminal. I have looked all over the web for the connector pigtail for it without any luck. I found info on the sensor that suggests it was used on '02-'04 LG3 4.3 v6's as well as the marine intake.
I can use the 3 pin map sensor ...

I suspect that's a MAP sensor on there - IAT sensors are pretty small and have only two wires on them.

Thanks for the help Matt !

MegaSquirt will control EDIS with out MJL or MJLjr.
One thing to keep in mind when converting to EDIS ign. is you still need the distributor shaft to drive the oil pump.
I belive Accel or MSD makes an oil pump drive for the chev V8 I dont know if the 4.3 V6 is the same,
or you could cut down a ...

This would probably have a stepper IAC valve, and as such I'd use a Megasquirt-II. Although that definitely isn't a swap you see everyday, it should be pretty straightforward from a wiring standpoint.

"Roger that "IAC valve,
I was leaning toward the Megasquirt -II , will it control the EDIS or ...

I am doing a '00 4.3 vortec / 700R4 swap into my '85 4runner- removing the 22re, I found this MPI intake for 4.3 vortec mercruiser (cheap) and could not resist. (24 lb. injectors, TPS, an odd looking vacuum operated fuel regulator and ...
