i bought a USED haltech E6K from a forum member a while back. i recently installed NEW injector clips onto the harness. when i un LOOMED the injector side of the harness i found this.


injec 1 went to the lite blue wire (injec 1)
injec 2 went to the blue/red wire (injec 2 )
injec 3 AND 4 BOTH went to GRN/red wire (injec 3)

red/grn +13.8 volts split between all 4 injectors

why did he do it this way and did i just save my motor?
the MAP i have is setup as followed (offline)
aux. in function diasbled
aux. out function ign toggle
injec 1 disabled
injec 2 disabled
injec 3 disabled
injec 4 disabled


im gonna guess and say the injec enable while the haltech is either plugged in the laptop ir see's 12 volts? cause the car ran this way the end of last summer??
even the wires were this way for the injectors?
could someone set me straight??

EDIT****
dont i need to use the DIG OUT 1 somewhere since its a 87 TII FC??

I think E6k's fire both trailing injectors at the same time regardless of other settings,

can someone else comment.


If this is the case then perhaps the #4 injector driver is bad, either way a single driver can handle 2 low imp injectors.

All injectors always share the same pos.

 

huh, i didnt know that?
so it IS allright then?
settings i posted are fine also?
i figured the inj need ot be enabled.

 

The correct wiring on K's and X's is as follows:

Inj1 to Front Primary (bottom)
Inj2 to Rear Primary (bottom)
Inj3 to Front Secondary (top)
Inj4 to Rear Secondary (top)

Fuel setup is Staging, and the ECU fires Inj1-2 all the time and Inj3-4 come on after a certain load point.

Slo's comment could be a possibility, test with a noid light on Inj4 to see if its firing.

If you use low impedance injectors always remember to set your Injector Current to 8A.

 

The E6k only does batchfire right, no sequential?

Correct me if I'm wrong, but doesn't it batchfire on a rotary by alternating 1 and 2 exept that the staged injectors are fired every time, so the staged injectors are effectivly multipoint.

 

No, the K and X when configured for Rotary mode only do a multipoint styled strategy, when set to stagging, 1 and 2 fire together at the same time, then when 3 and 4 come in, they all fire together.

With the E8 and E11, you get the benefit of sequential as well as staging, where 1 and 2 fire alternatively, and then when 3 and 4 come on its a 1 2 3 4 deal.

 

which begs the question, why not just have 2 injector channels 1 for primary one for secondary. The others could be configured as additional injectors if needed.

 

If the secondaries are both high impedence, then it'll all still work.

I agree with the suspicion that INJ4 is dead.

they will be firing a set of ford 1680's (secindaries).

 

im the guy he bought the e6k from
*disclaimer* im not a haltech expert or even a novice tuner.
this might help you understand why that is the way it is

i bought that e6k brand new from aus. i originally ordered it with a 6 injector harness custom made for my set up. at that time i was running 2 850 primarys, 2x1600 secondaries, and another 2x1600 tertiary's. (sp?) they sent me the injector harness complete ready to plug and play. i wired the car myself and it started fine on the first atempt. at no time was there any crossed wires, shorted this, or blown that.

after a few months of trying to get a smooth transition between the 850 primarys and 4x1600 secondaries (near impossible) i decided that i wanted to disable 2 of the 1600 secondaries. i asked ppl on the haltech yahoo group if i could just unplug 2 of the secondaries and drive it that way. most ppl said that i should rewire the injector harness to a 4 injector set-up.

now i'll admit that i'm a novice when it comes to electrical stuff, so i called my haltech guy in aus that had originally made the custom 6 injector harness and i asked him "how do i make this into a standard 4 injector harness" he e mailed me a color diagram showing me what to do and i followed that. after modifying the harness the car ran flawlessly with better, smoother staging.

the ecu was never shorted or damaged, i can assure you that there is nothing wrong with inj 4 in that ecu.

what i suspect happened is this.
the haltech guy in aus used inj 1 & 2 for the primarys (as usual)
he then used inj 3 for BOTH secondary 1600's
and inj 4 for BOTH tertiary 1600's

the only 6 injector harness haltech makes is for a v6 engine wich wont work on a 2 rotor the way i needed it to. this guy custom made me the harness the only way it could run all those injectors properly.

either he sent me incorrect diagrams for rewiring the harness, or i didnt follow them correctly, but either way. i know that IT WILL WORK wired the way it is as ted stated, and i can assure you the wireing is not that way to compensate for a dead inj 4.

rewire it if you like, or just buy a standard 4 injector harness from them.

hope that helps clear some of this up. let me know when you get the car running.

 

is this for the e6k also? i have high impendence primaries and low impendence secondaries, where do i change this setting?

 

im running an E6K

thank you for clearing this up. like stated, i am not bashing or second guessing your wiring work....we all know how much work and $ it takes to make a reliable HP rotary. i was only covering my grounds and second guessing my OWN work. i will prob. just go ahead and wire injec 4 to my other clip to avoid confuse for myself and tuner.
again, thanks SO much for the clear descriptive reply and help. i will def. let you know when its running. my ETA will be next weekend. *HOPEFULLY* if things go well with the rest of the install....

 

no problem, i know you werent bashing, im just trying to be helpful

 

I know this is a blast from the past . But didn't want to make a new thread yet for no reason . I'm running a e6k 6.34 with low imp 850/1600 combo . the way I'm wired up is a driver for each injector . I'm trying to solve a rich problem at idle and want to make sure everything is setup right .
