The 5th Gen Piggyback/Tuning Thread
Spoke with RT TUNING in Lansdale, PA yesterday and they told me that the greddy emanage units are glitchy and all the guys they have come in there with them are unsatisfied with results on those. He also said that the software is wierd to work with. He said emanage blue was discontinued because of problems and emanage ultimate is not any better...said people have burned up ignition coils with them. The guy recommended the AEM FIC universal unit $370....he said that works on all cars and they have used it successfully and everyone they have used it on was happy....he also said software is really easy to work with. He told me that to advance timing correctly I would need a stand alone AEM universal unit....$1800!! HELL NAW!! But he told me that the power gains from advancing timing wont be worth the extra $1000 + dollars...he said advancing timing does not really give you THAT much more power and adjusting fuel curve is what is going to smooth the power curve out and give the car a safe ride. He also said with an AEM stand alone unit will not pass inspection because no longer OBDII....but with FIC controller it will. I will just get AEM FIC and use that and when I get done post my dyno chart on here so you guys can see the numbers........waiting on cattman catback(he need more orders)....then I can put everything on and get a BEFORE (with mods untuned) and after(mods with tune) dyno. Guy was very informative on the phone...he is the "Nissan" expert there, he said he has tuned Maximas, 350z's, and G35s.
Why not just read on this forum, in this thread, and in the AM forums what people have done on here with your same car?
I'm sure he's knowledgeable and all that, but the people on here have first hand knowledge on the subject.
There have been some successful candidates that have used the EMU without any problems. Others have fried coils.
The EMB has also been used successfully and it also has been proven to advance timing and not burn up coils. Although the advancing timing interface on it is bit more tedious than the EMU.
Then there is the ultra crude AFC timing method. (Add mucho fuel, either via larger injectors &/or added fuel pressure, remove fuel to add a large voltage correction via said AFC) and this indirectly adds timing.
Then there is the UTEC. This is probably the best option right now, albeit sans a few quirks when cold for a slight misfire. One of the most powerful Maximas on here uses it. It adds timing, and can alter fuel maps (along with raise the rev limiter).
Couple the aforementioned UTEC with a healthy set of bolt-ons and a Greddy V-manage for good measure, and you're cooking with Crisco.
Just an FYI, there are many threads on these subjects.
If these types of posts keep up, this will become a closed sticky and then whoever wants to ask a question, or post some useful items, they can PM me or someone else from the staff and it will then be served on a case by case basis. From the very first post:

If the UTEC was such a great unit.....why Turbo XS discontinue it? Everyone on here seems to have had great experiences with it, except misfires when its cold......other than that I haven't read anything negative. What the heck??
It's a good option for US, but not the general tuning community (Z33, etc.) Their ECU's are more advanced so newer technology has made it easier for them (company's) to make better products.
But, UTEC is gold for us step children of the ECU people.

. Its diffrent between the 5th gen and 5.5 gen...Theres 01-00 diagram kicken around here somewere , took me a while to find it aswell .
yeh...and their dam near impossible to find! Finally got the money to buy one and can't get it....
Yes, they are but alot of places have them sitting in warehouses somewhere. Like NMex said...the 350z guys have alot more options as far as tuning goes....but these are GOLDEN for the Maximas. Surratt does the wiring harness to make it plug and play too. I bought mine brand new off ebay.....preferred to have mine like that rather than buy used from someone and you don't know what condition its in. They are definitely still around....you just have to look for them.

I don't know the part number go to turbo XS website and perhaps it will tell you there. You can always just do a google search on Turbo XS UTEC for 350z...alot of information about the UTEC is on this forum as well...try and do some searches on this forum as well. I don't think you really need a part number....

OK...I was reading through DECKOUT's VQ35DE N/A build forum.....and him and Aaron said that the UTEC doesn't keep the fuel ratios? Aaron said after a month or so he has to go and retune it on the street? W T H??? Has anoyone else had this problem with the UTEC? I know sparks has one....anyone else notice that after sometime its changing fuel maps on its own?
I didn't know that. I seen deckout and Aaron both complaining about it and I read about some people on the 350z forum that had the same issue of it just losing fuel maps after some time. I hope I don't have that problem. I plan on doing a similar engine build like Deck...pistons, connecting rods, cams, spring/retainer kit, injectors, 3" MAF...along with headers, catback, spacers, BOP, intake all the typical bolt ons as well.....and meth injection to run more timing.

I am a noob when it comes to ECU tuning. I read through alot of this thread (not all) and it seems like the more I read, the more confused I get.
I have a '03 6MT and right now I just have Cattman headers and NWP spacers. In the future I may do a few more basic bolt-ons (BOP, SRI, 3" exhaust & fastcat) but nothing more extreme than that.
I was leaning towards the EMU until I read about fried coils (I want nothing to do with that) I have limited funds and the EMU would've been at the VERY tip of my budget.
What tuner would you recommend to be used with Innovative LC-1 WB? (that's the one I'm looking at getting)
Another thing I should mention is that I will not personally be messing with any of the settings. Once I have a shop dyno-tune it, I will not be touching it, as I know almost nothing when it comes to tuning.

Max $700 on tuner, $200 WB
http://www.amazon.com/Innovate-Motor.../dp/B000CO7TXK Is this the right one?

Dyno was a Superflow WinDyn V2.7 with atmospheric(read weather conditions) compensation. 2002 Max w/auto. Only have bolt ons, no actual tuning. Looking for a way to post the dyno........
AFR starts and holds at 14.8 until about 75 mph and then dips to about 13 at 85 mph then eases down to about 11.5-12.0 by the time I hit 125 mph. Third gear pull.........

Custom tuning > off the shelf. I can't quantify it, but the theory behind dialing in each specific application exactly makes the most sense.

Technosquare does not do flashes for these cars anymore, from what I've seen. However, lots of people used to piggyback the TS flashes with an SAFC for fine tuning.

How do you know you're running rich? Better get a WB before you go changing settings, or get on a dyno.
