kenny.
kenny.
When you get your new ecu running, we'd love to hear how it goes!

Yeppers... the JWT ecu upgrade requires an 88-89 n/a ecu & some different re-wiring than the 84-86 Z31T swap.

Well, I supplied them an '88 turbo ecu, thats why I have to do a wiring harness to ecu upgrade and a downpipe bung hole upgrade.
I can assure you that I will post the results of a killer plug and play, no hassel no drama, [I hope] upgrade of my car.
I hope you find the source of your problems.

yeah i don't no WTf. I was driving it after i swaped in the speedo from Shady, And it died, and wouldn't start. Just like one of them wires were disconnected from the ecu again. Then when it did start, and i was uping the rpm to move it, it died. So i don't no, smells hella rich again, and won't go anywhere, it did this 5 times. Oh and then after it didn't idle anymore. So next jy trip, i'm getting a new Maf, chts, and some parts for the s30...Hopefully it'll work when i'm in cali, before the swap.

I hope you figure it out.

yeah, were brothers....you have a problem! no why cause we have stupid problems, man that **** sucks, i think it has something to do with my spark plugs/ wires or distributor. something electrical. after i swap out the manifold, cause it has something to do with vacuum problems, then it should be fixed...

hey guys. so I am getting ready to do the Z31 swap, and I am getting the wiring ready to go and have a few questions... first go is the MAF... in the tutorial is shows that the wiring changes are:
Now, I see how all of the colored wires run in, but wires #2 and #4 are confusing me... all they say are "b" wires, and after matching up the colored wires I am left with a black wire with a blue stripe on it and then a thick gray wire, which when stripped shows a black covered wire wrapped in aluminum wiring...
which of these 2 wires goes where?
should help greatly with the swap since it isn't too clear...
CONNECTING THE MAF:
Cut the wires to the AFM a few inches back from the clip
Take clip and wire from MAF then:
1) Connect MAF Position A/wire 30 y/g to 30 y/b wire from z harness
2) Connect MAF Position B/wire 31 b to 31 y/r wire from z harness
3) Connect MAF Position C/wire black to body ground
4) Connect MAF Position D/wire 26 b to 26 b wire from z harness
5) Connect MAF Position E/wire 27/35 b/w to any ignition activated + powered wire (pin 27 and 35 are + ignition wires on the same circuit, they are b/w (black with white strip) and can be tapped into from either b/w wire going to the 2 V.C.M solenoids that are located under the AFM bracket
6) Connect MAF Position F/wire 12 r/w (for cleaning cycle) to 33 y/l wire from z harness

haha no I was being serious.... the tutorial was talking about 3 different black wires and I had no clue which was which.... but by taking the boot off I can see that they go in order down the harness... didn't even think to take it off...

hmm, i can probably borrow one, but i haven't got one myself...i got an idea, if i can get all the ****, done swaping the .et motor in the 240z. Then when msa comes up you can come down, and help with it...Then sport your zx and the z at msa...That'd be badd...I know this is off topic, but what all is needed for the turbo swap into the z. Like driveshaft is what i'm worried about?

I knew that would be a bitch....the car comes with a 4 speed but i'll probably just keep it for extra....damn and this megasquirt instructions are hella confusing, damn i'm going to need some help....Well Nismo i'll give you a rolling shell for help with installing this here megasquirt.
