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

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

Look on page 46 (Section 19) :D

It is for some mazda motors.

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.

      Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.

      Jacks that fit under GTR lips that can reach the subframe?

      My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though.

      Duncan's V37.......race car?

      By Duncan · Posted

      Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno

      Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
