OK guys here is the news...I've hooked up the igniton harness with no problems. Each one of the signal wires going to the coils has had a 1W 3.3V Zener diode placed in series...REVERSED BIASED. Basically this means that any signal from the e-manage below 3.3V will not be able to go to the coils...meaning that there is NO idle current load on them. This also means that the 5V signal from the e-manage is actually 1.7V...much closer to the factory signal voltage (Zeners work by allowing only a voltage flow over what they are rated as....therfore 5v - 3.3v = 1.7v)

I've noticed no ill effects on the auto shifting...in fact it's improved for me as the CAS is now set back to it's factory position, with only the problem RPM points retarded.

I hope that for some of you this is good news.

Sounds fantastic to me!

More kilowatts in th making!

Forgot to mention that the check engine light comes on when the harness is wired in, this is due to the ECU self-check on start-up. This can be eliminated by getting the GReddy e-manage ignition signal adaptor…as far as I know this is only applicable to the R34 and WGNC34.

This however doesn’t interfere with the performance of the car, just is annoying to see it on the whole time.

Another thing guys....the e-manage 100% allows the timing to be advanced...I know this has been a source of discussion as to how it does it....it just does :P

At Idle advancing 10 degrees there is a noticable change in pitch from the engine, retard 10 degrees and it reverts back to normal. Proving the "psychic" abilites of the e-manage to predict the timing and therefore advance it actually works!!!

It's actually most likely as someone suggested...running the timing a cylinder out and reordering it in the correct firing sequence....to mimic and advanced state.

Hi Dan, what does "with only the problem RPM points retarded" mean?

SK...my car is an N/A with a turbo bolted on....problem RPM points just reffered to the factory ECU...where the timing is a bit too agressive under boost. It's the odd RPM point through the MAP that needs to be retarded a tad.

A little off topic but I remember reading in a magazine that Apexi are now making power fcs for auto chasers, so they must have come up with the know how to control the shifts.

Toyota shift logic is not the same as Nissans, not as good either :)

Additional bit of news...those who connect the ignition harness and find the engine check light stays on (R34 and WGNC34) The supplimental harness from Greddy works and prevents the light falsely turning on.

Wonder if that works on the R33 series 2 as well. I get the engine check light too now I have the ignition harness connected.

On another note I tried one of the new GReddy E-manage knock sensor adaptors the other day on my RB25......it didn't work. Just throws a knock sensor fault :rofl:

From trust's website.

GReddy e-manage Ignition signalAdapter 1  

The occasion where in vehicle (ER34 ・ WGNC34 and the like) of neostraight 6 the ignition harness of e-manage is installed, the factthat the check lamp of vehicle side lights up is preventedAdapterThe 。which is  

Each ignition signal input of e-manage (ECU side) to the line and theground the 。which wires  

To 6CH the 。which corresponds  

CODE: 15900906  

Price including tax: 1,890 tax removal price: 1,800  

mambastu....funny stuff I bought one of those knock harnesses too! Yeah it makes the timing retard more than ever...must just be the way the nissan ECU works.

The check engine light one is good though, I don't have that annoying orange thing glaring at me anymore :rofl:

It probably would work on the SII as it uses the same coil-packs.....

Thinking of getting emanage and Profec e-01 boost controller for my r32, how does this compare with a powerfc with hand controller and boost kit? The emanage with all options and the profece-01 work out to be cheaper than the special r32 gtst powerfc, with boost solenoid and handcontroller.

Hi xRHETTx, Emanage is an interceptor, it takes signals from the sensors and bends them, so the standard ECU still runs the engine. A Power FC (FC = Full Computer) replaces the standard ECU completely. There is no comparison, you will NEVER be able to do with an Emanage what you can with a Power FC.

For an R32 you really should look at tuning your standard computer. A simple rewritable chip upgrade will give you everything the Emanage will, plus a bit more. The Power FC is another couple of steps up of course.

So it really depends on your power target and what upgrades you intend to do.

Hope that helps :)

Hey all...

Im needing some help with the E-manage...

im looking to see if anyone has some fuel maps that they could share or dissuss with me...

its for a Rb20det engine...its not in a skyline but i thought this would be the best place to ask for a helping hand..

Thanks

Remapping the original ECU is probably the best option. PM or e-mail me if you need further details...

Hi Guys i have just bought the emanage for my r32 gts-t with the ignition and fuel looms, but in the box with the main unit there is a small resistor and a connector in a seprate bag, now i have looked through the manuals but cannot find were this is to be used, i have the e-manage in the and the car runs, but i dont want to go to far without finding what this is for?, any help is good?.

Thanks

Nathan

Look on page 46 (Section 19) :D

It is for some mazda motors.

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
