7mgte AEM Sequential injector wiring

[SupraMKIII-NO]

Hi!

First of all, sorry about my bad english skills (from Norway)

I have the RC1000 injectors and want to wire them up to my AEM EMS (supra mk3 -89). I want to wire them in as "sequential", how do i do this? Each injector has 2 wires, where should they go? I will think that one of the wires on each injector goes to the AEM, but where should the other wires go? Is it "constant power" and "trigger signal"? or is it "trigger signal" and "ground wire"??

Hope somebody can help me =)

on each injector 1 wire gets 12 volts the other gets the signal from the ecm. youll have to look at the aem pinout to see which avail. inj drivers you have and where theyre located.

On Toyota, 12V is constant, the PCM supplies the ground. As pointed out in post two. No comment on AEM strategy. I thought the AEM was plug and tune, and you plug it into the cars harness. Is that not correct?

V1 I thought you cant do sequential, they have 6 inputs for the ECU but they are bridge internally

sequential injection yes

its the ignition that is limited, but there are ways around it.

Yeah like buying proefi!

About this proefi.. how do we go about hooking this up as opposed to the aem? is it plug and play as well? I have been leaning toward the aem 1130 plug n play for mine but trying to see if its worth the 1800?!

I heard great things about the ProEfi, but since it is not plug and play, my shop wanted over $800 just to do the wiring. I went pnp AEM instead. About as pnp as you're going to get right now. Spend $65 on a dh61 ignitor and splice it's ten wires into your factory ignitor harness and you'll be able to calibrate for sequential ignition. Running it now myself. The AEM doesn't seem to have any issues except the annoying iacv control issues. Thinking of just capping it off at this point and adjusting the cold start injector settings for idle.

But that with resistor ?

Are the injectors high current? Aka low impedance? As is low resistance, and subsequently higher current to open.
