Want To Install A Piggy Back Ecu

[bosco]

I want to get the Greddy emanage ultimate piggy back for the v35 but dont know much about it.... Can anyone help? anygood dyno tuners? is the greddy any good?

Where are you located? There is only one tuner in Melbourne I know of that has managed the install on my VQ25det, Cihan (Etuner). Trent at Status should be able to help too.

Understand the Emanage ultimate will be fighting the factory ecu the whole way. What do you hope to adjust with it and what are your goals?

I am located in NSW. I current got cold air inatke, custom manifold, full xforce exhaust, skunk2 plenum spaces. I am just looking to get more power from the mod i got atm....any other ecu maybe that are not too expensive?

cheers

You could try cough... Cryodon Motorsport... cough (I know there are some out there that don't like their work) but I was quoted $1400 for a drive-in, drive-out deal of a Haltech Platinum Interceptor (the Piggy Back one), wiring loom and tune. Which seemed reasonable when I costed the other options.

They said they had done a couple of V's and were getting peak gains of 10-15rwkw and much better bottom-end and midrange. These were on stock cars and some with Cat back exhaust and Cold Air intakes.

I'm told by my mechanic that if you are thinking Forced Induction later on, go with the Haltech because it has enough functionality to handle the F.I. and the E-Manage doesn't, though others who have FI might have a different opinion but I'm just adding that incase it's part of your decision process.

If you go for the E-Manage (which I was going to do when a friend was parting out his car), just be mindful that the loom can be $300-$400 and most places want anything up to $600 for a tune (if they aren't selling you the whole package), so it can work out more expensive and with no warranty coverage.

If you do want to go with the E-Manage, I'd say you could also try Just Engine Management (J.E.M.) at Ingleburn (SW Sydney), they have done a few R33's with the E-Manage and the owners were happy.

Ultimate with a boost sensor will handle the FI no problems. I have heard differently with regards to the Haltech, heaps of problems. Definitely do not rush in, there isnt much in the way of experience with these ecu's and you don't want to be paying for the tuner's learning curve on the dyno.

Good to hear both sides of the options. I might have to do some more reading before I head down the Haltech path too then!

E-manage Ultimate has much better options list than Haltech Interceptor. (Side note: if your car supports phasing on inlet AND exhaust cam, Haltech Interceptor won't work). EMU is quite comprehensive, but like Scott mentioned you are effectively bound by factory ECU programming ... there are good and bad points to this fact however.

That said I am having trouble with my own EMU install, so if anyone can help (and sorry to hijack thread) ... my EMU is reading a constant +5v TPS (5.07V to be exact) at startup which is triggering anti-foul mode on the EMU and cutting fuel. So the car is cranking with spark (presumably) but isn't starting...I haven't had a lot of time to get into it but suspect either faulty harness or some sort of interference. I don't think it's a wiring issue, but could be wrong. EMU is running latest firmware and using supplied N13 harness. It has actually started a couple of times, but for the most part...no go. Not sure if anyone has had similar issues with their installs? I haven't tested the TPS voltage coming out of the ECU yet.

i got the haltech platinum interceptor piggyback installed and setup by crd for $1350. got 180kwatw with full exhaust(headers, cats etc) ztube, pop charger, unorthodox pulleys, plenum spacer. ive since fitted a truel dual and will be installing test pipes so hopefully should see 190kw with a new tune. Going to get matt from hitman to do the tune.

I just wanted the unichip originally but i was told by almost every workshop to go for the haltech.

You were definitely wise to avoid the Unichip. Although, has anyone here considered the Uprev Osiris? Seems like a lot of turbo kits in the US use this particular set up as there's no wiring to mess about with and you're no longer at the mercy of the maps determined by Nissan.

I looked into the uprev osiris over a year ago..

I emailed Richard (i think), and it was all good till i said it was a for a jdm V35 350gt...he said without knowing for sure if the ecu's are exactly the same as in the g35's, i might've run into issues when i attempted to reflash with their software so i didn't go for it in the end. He did say if i pulled part numbers he could cross reference but i don't speak japanese lol.

I then looked into emanage ultimate and was really keen on it..in the end i didn't use the emanage because my mech was flooded with work and i only wanted him to tune it plus didn't really want to introduce extra electronics feeding vital signals to the ecu.. not common but i've heard of a few cases of the piggyback failing.

Settled for a custom ecu reflash in the end but still not entirely happy...lost alot of low end (remove damn factory aggressive settings causing knock) but gained a fair bit top end...now the motor is peaky - great for spirited driving but car is not as strong a i'd like just poddling around.

Currently looking into open ecu and associated cables for the V or something similar..then my V will be the test guinea cop at my mech. If all goes well, after mine, the garage will start doing V/Z ecu tuning officially.

How much did u pay for the harness and emu

[Kam-80]

Around $1K for EMU + harness.

Trent told me a while ago that he has already installed and tuned a V35 with an eManage Ultimate successfully.

I see. So in which case, other than the cross-referencing, one way to check would be to try the Osiris Tuner version and extract the existing maps first to see if the Osiris is really capable.

On the other hand, another desperation tactic (though very expensive) would be to replace the ECU with the US version provided they're pin compatible and then go to town on it. Either that or go for a MoTeC M800.

I'm starting to think I shouldn't have sold my M800 last year...

Yeah that thought crossed my mind before lol...buying a used g35 ecu on American ebay (cheap as chips), send it to uprev for fiddling then get sent to Aus for install...but the pinouts may be different plus would they know how to tune for the fuel we have here ..

Like you said, one way to try is to buy the pro tuner/diy version, plug everything in and see if it works but if it doesn't...you're out ~1300 ausd last i checked.

Btw, the factory ecu in our cars are quite adaptive/dynamic, constantly changing the ignition timing, something to consider if you go piggyback. Not saying can't be done, just there's more consideration vs a performance car from the 90's in general.

[Touge Kyousou]

I checked the old email from Uprev. They need a ROM number, AKA the ecu part number. THey said it can't be located on the vehicle anywhere and it's obtained from the dealership parts department. "As long as they have the ROM for our vehicle patched, they should be able to help us"

[The Max]

Hmm. More homework for me then when the time comes.
