Im nearly done with this intake swap. Deleted emissions parts and just kept everything simple. Only keeping the necessary things. Trying to avoid any issues beforehand, so when i start the truck, itll be good to go. Seeing others having issues with their MAF from 240 and seeing others say it needs to be grounded.... how exactly is that done?
When i peeled back the old tape around wires from the connector for truck MAF, i saw a bare wire strand wrapped around 2 of the 3 cables going to the MAF plug. Would that be the ground wire for the MAF? if anyone happens to have pics of their ground for the MAF, that would be awesome.

Or is the ground the black/white wire? if so, i just need to make sure that, that wire is connected to the right pin?

Are you using the 240 maf or a modified truck maf? I'll post up the wiring as soon as I know what you're workin with.

I’m using 240 maf

Also, for the air regulator. Where/how did you wire it up for KOER power? Does one wire go to power and other to ground? 2 wires for the plug.

I found the same bare wire and just left it alone, and I just hooked up both of the aac wires into the fuel pump relay wiring, seems to idle fine.
I cant seem to get the pos out of limp mode though.... no vacuum leaks, added a ground to the maf, bought a new maf, and tried both the truck ecu and the 240 ecu

im guessing it has to be in the wiring of the maf but ive tried both ways (black to white) and (black to black, white to white)

Does it matter if the ecu is off a auto 240 swapping it to a manual d21?

No, most people run the auto one due to the lack of rev limiter. I've been running an auto ecu for 3 yrs with no issues.

OK I’m new here so go easy please I have a 1987D 21 with a carb z24I I recently picked up a 1995 ka24etruck block with the 240 intake swap. After reading all of the wiring and what not I become incredibly concerned about my ability to finish something like that and the patients involved. I’d like to get my truck up and running ASAP. My question is can I convert the KA 24e to carbureted with the 240 cam get it installed and revisit this later when I have the time,parts,patience to finish it ?

It will be easier just to do the 240 swap than the carb conversion on the ka. It's not that hard to do. Mainly moving stuff around. The 240 maf wiring swaps 2 wires from the way the truck is wired.

Will this work for an automatic D21? Would one need to get the ECU from an auto 240sx?

Sure it would work, just need the auto throttle cable bracket for transmission kickdown cable. It will run with either ecu.
