And to feed the beast

I'm impressed. Do you order the MS ECU with the right connector for the harness or do you have to use some sort of daughterboard/motherbaord adapter, programming, mapping, or some other sparky term I'm not familiar with to ensure all the pins on the connector go to the right components on the MS ECU?

 

[Devil Frog]

there are MS DIY PNP kits available with the same connector for many common ECUs

There is a main board that is common for all the MS DIY PNP kits, and then an adapter board that makes it PNP for your particular harness. I got the kit for the 52 Pin Nippon Denso ECU, there were instructions to build it to run a 5MGE and 3SGE, but not a 3FE. I had to map the appropriate signals to the respective pins using this diagram from the 3FE FSM:

This was the mapping

see, what I am doing with the wiring harness is the same as doing this.

Oh man, us sparkys really love this crap.....glad I ain't doing all this work though!

Fuel tank is ready to go

Tub is off frame

Supra injectors are in, and the rail has been converted to AN-06 for compatibility with the Aeromotive fuel system.

 

[cruisermatt]

Could one use supra injectors with no other mods? How much of a difference is there?

You need a programable ECU for any injectors other than the OEM speced

Got it thanks. About to send mine to RC to be rebuilt, was just curious about other ways to polish these tractors

Injectors alone will not get you increased performance. You need to increase air flow AND fuel flow somewhat proportionately. Have you done anything to increase airflow? There are lots of options, cams, displacement (2F bottom end), port and polish, forced induction, desmog. The factory EFI system should be able to support a modest increase maybe 15-20%.

I got the tank in, but it is not a nice secure fit, pretty much rides in the skid plate. Evaluating options for snugging it up.

 

[Devil Frog]

Somewhat of a rolling chassis

Some progress from my body and paint guy:

 

[Devil Frog]

Clutch and tranny installed

 

[Devil Frog]

My implementation of Jstncse's air elocker conversion

 

[jstncse]

Too cool, I love the operation of that valve
