Removed Posted January 15, 2006 Share Posted January 15, 2006 ... I've been doing a bit of reading on this, basically a stand-alone managemnt system? If I understand correctly, you'll have decent gains on N/A and if/when you go FI you'll already have a very good management system..... question is.... is it going to work on our UK cars? Anyone?

Removed Posted January 15, 2006 Author Share Posted January 15, 2006 hmmm just found some interesting info on the UTEC gains on a N/A car on my350z.com...... think this is going to be my next performance mod (if it works on our car and find someone in this country who knows what to do with it) http://my350z.com/forum/showthread.php?t=161922 Quote Link to comment Share on other sites More sharing options...
Guest prescience Posted January 15, 2006 Share Posted January 15, 2006 As you've no doubt discovered from your reading (as I have) the UTEC is the next generation in EMS for 350z. It is still works with the stock ECU in place but effectively is in complete control of the engine fuel, timing etc. Other than that, one major difference to other piggy-backs (there are a few differences) is the ability to set timing directly. Other piggy-backs set a timing offset, so you're guessing what timing advance the stock ECU is applying in a given situation. This seems to me a major improvement. However, as we all know, in the past when a modification (e.g. higher flow exhaust, better designed plenum etc) has been made there is often a temporary improvement in performance but evidence to suggest that somehow the stock ECU learns the mod. and dials the improvement out - at least at top-end revs; there still seems evidence that mid-range gains are retained. With the UTEC, there is the real potential that the improvement from the modification can not only be retained long-term but be optimised. Questions remain, which will become clearer over time no doubt. For example how does the UTEC respond when we put 95 RON fuel in. It has a knock sensor and we can only assume it works in the same way as the stock ECU by reducing timing advance during knock - but does it do this progressively or with a fixed offset (strongly suspect the former). We need to be assured that the UTEC has the same safety criteria inherent in its design to ensure safe and reliable operation. The most major point is as you have raised above is the need to get a tuner competent to tune it. This does not exist at present AFAIK in the UK and no doubt it is a specialist skill. You're trusting your tuner to do as good a job in getting your car to run safely as Nissan R&D did. One consolation is that I believe a variant (earlier and simpler by all accounts) of the UTEC is in regular use on Scoobys - so that may be one tuning avenue. IMHO until the tuning question is resolved, spending probably about £1k on this is questionable. Although longer-term, that may change.

Removed Posted January 15, 2006 Author Share Posted January 15, 2006 valid points, and also the tuner point, possibly current Subaru tuners might be willing/able to work on the Z UTEC? The unit does seem to be doing a great job, for both modded N/A and F?I cars! Quote Link to comment Share on other sites More sharing options...
Z1 Performance Posted January 15, 2006 Share Posted January 15, 2006 The Z UTEC works similarly in many aspects to the WRX one provided yo are tuning via MAF. For you forced induction people, tuning is done with the MAP sensor option - frankly any competant tuner who is used to standalone mapping via MOTEC, GEMS, AEM EMS, Electromotive, etc will have no issues programming it at all. Like any other system, it takes a bit of time to learn the ins and outs, but it is very user friendly, and its combination of on board datalogging and integration with a wideband 02 via the Tuner or Tuner Pro makes it a great combo Quote Link to comment Share on other sites More sharing options...
Guest prescience Posted January 15, 2006 Share Posted January 15, 2006 How easy is the install - compared to say SplitSec with Vortech.? Does it come with a ready-fit harness? Can it be shipped with one of the maps pre-tuned (safe) for Vortech S/C? Another great feature I heard about is valet mode - to stop these Nissan boys thrashing the nuts off it when its in for service Great input BTW Quote Link to comment Share on other sites More sharing options...
Z1 Performance Posted January 15, 2006 Share Posted January 15, 2006 How easy is the install...well, let's see First, yes it is plug and play. No wiring, splicing, soldering of any kind. But, it is a very very very tight fit...takes a bit of careful manuevering to get it back into the car. Quote Link to comment Share on other sites More sharing options...
Removed Posted January 16, 2006 Author Share Posted January 16, 2006 Adam, this is (I hope) the chapter on our UK manual where the ECM (as they call it, not ecu, I suppose it's the same) is analysed in detail, I'm sure you'll be able to find out if it has the same pinout diagram as the US one (for compatibility with the UTEC). It's over 6MB though, I'll have to email it to you as it wont seem to upload it Quote Link to comment Share on other sites More sharing options...
Guest prescience Posted January 16, 2006 Share Posted January 16, 2006 Here is the answer to my question on knock-handling courtesy of info. on ForgedInternals.com. Basically, the UTEC detects knock and you can set the threshold at which ignition retard is applied, how much is applied and when it is 'unapplied'. Full control therefore Knock Control- This feature allows you to help keep your motor in one piece. The UTEC contains default knock thresholds but can be adjusted at 1000 rpm increments up to 9000 rpm. It also contains a Knock Count threshold that allows you to define how many counts of knock before the UTEC will respond with a Knock Retard Step. The Knock Retard Step is the amount of ignition timing that will be pulled per knock count to a defined Knock Maximum Retard. Knock Maximum Retard relates to the maximum degrees of timing the UTEC will retard per knock event. When a knock count is registered the UTEC will hold the retard for a set number of crank cycles this is called Knock Retard Duration. The UTEC also has the ability to apply a global Knock Correction to the entire map once a knock event is evident. This will help ensure that you keep your high compression monster together. All of these features are the UTEC’s safety net. They should be used pro-active not as a reactive measure. Quote Link to comment Share on other sites More sharing options...
StephenG Posted January 16, 2006 Share Posted January 16, 2006 From my old Celica days, you lost quite a lot of 'European only' ECU stuff when you swapped over a replacement ECU; to wit, the immobilizer, climate control, and some other in-car electrics. Any danger of that happening here? I know it's an 'advanced' level piggy back, but would there be any ECU stuff that would cease to work with this unit?

Removed Posted January 16, 2006 Author Share Posted January 16, 2006 this is not a replacement ECU. It's in effect an EMU, that leaves the ECU do the "trvial" everyday work Quote Link to comment Share on other sites More sharing options...

StephenG Posted January 17, 2006 Share Posted January 17, 2006 hence my slowly growing interest... seriously though, the Apexi PowerFC unit (which I don't believe exists for our engine) was a very impressive piece of kit, and I'd like to see similar for the Z.

I will let you have ECU pinouts soon. Anyone you would recommend to install and tune your UTEC then in the United Kingdom??? Thanks again Jermaine! PS surely I've seen you posting on 350z-tech.com?
