hehe davidv. you can but i actually am using prices i've been quoted. i have a lot of interest in utec and i've asked around.

 

Sharif is charging $660 to tune the UTEC.

Respect
JET

 

Itll go down as people become more and more expierienced with it. 660 is probably for a FI tune. NA tune would be dramatically less.

 

"Then be my guest and purchase the UTEC and try having someone tune your car better and get 1 or 2 more rwhp out of it over a reflash."



Just for ur info chebosto, we tuned almost 9whp out of a EU on an NA Z, and from what I have been told the utec has some bugs but you should be able to match that with the utec

 

this is absolutely not the case whatsoever...and in fact, even on a flashed ecu, multiple maps still exist (I ahd a flashed ecu's and the multiple datalogs showing it differed based on how you rolled into the throttle)

The UTEC runs what you tell it to...all with being full in tune with temp compensation, as well as with the knock sensor.

The flash works great, don't get me wrong. The biggest issue with them is the simple fact that it needs to be done on the car IMHO...not something you want to do mailorder. The flash on my car netted 12 whp and 11 lbs feet. However, the UTEC bested that by an additional 12 peak and 9 ft lb gains, with gains up top close to 18 whp

 

Factory ECU limits throttle to i believe 70% at WOT.
Reflash opens it up all the way.

 

I heard 80%, but then heard later that it wasn't true; that it opens up all the way just fine.

 

I had the spec flash and my OBDII showed the TB at WOT was at 85% . I called TS and he said the 100% TB will not show up on the OBD . This was over a year ago and dont know if its true or he was BSing me . But I dont see why they would claim to be able to do it , if they couldnt

 

mine showed 89% as stock, and 89% after the flash. If the tps is doing it, the logger sees it

 

turboxs.com: "Typically, we charge $600."

alteredatmosphere.com: "dyno time / tuning costs $385
We typically spend at least two + hours when we setup/tune the UTEC for a NA 350Z/G35."

racemrc.com: I guess friendly race shop price

z1auto.com: ?

 

we dont quote tuning prices as every car is different- some play nicely, and some don't.

 

^+1 I was told the same. 1-3 hours, maybe more on a NA car

 

This might be a stupid question but is there anything a reflash provides that a utec wouldn't be able to provide?? Can a utec raise rev limiter?

 

As quoted by Z1 Performance:

yes it can on 03 and 04 models....soon to be able to control it on 05's with a future software update

 

is'nt this just all in voltage issue.. some cars i guess use a wider range of voltage say .45 to 4.5 volts to get the 0 percent and 100.. so for say our car just goes up to 4.2 volts for wot.. sure ecu knows its wot but on data logger might show 85 percent or something.. so yes whoever said that the car does not open up 100 percent stock is bs or well just don't know what they are talking about.

 

So if UTEC can replace all maps, then reflashs are a thing of the past?

 

So what can a reflash actually do that a utec cant? Im guessing it'll be pointless to get both, which was what i was planning to do. But if the relash doesn't offer any additional benefits then theres no point to get both now.

 

I would call your opinion a bit biased, as are mine for obvious reasons, however I will say there in nothing better than a custom tune on the car itself. Plus I am not comfortable with sending my ECU across the country in a box.But that is just me..Plus a Reflash does not store 5 seperate maps and offer data loging as well as free software upgrades and maps. The UTEC is far superior to a reflash in every way concievable..

 

As far as self adjustability, yes. Utec can't be beat. for $1800 in parts and tuning, you better get every you need. NA or FI...

For me and others who dont want the hassle of trying to finding an authorized tuner, a flash can do everything i want the car to do to while safely boosting up to 1 bar for 1/3rd the cost. I abuse the Z just as hard as anyone can imagine. and i'm fine with my reflash. I'm biased against the fact that the thread started claimed it as a Rip Off. and i highly disagree with that statement.

 

With all due respect to Cheston, a UTEC is not $1800.00 - it is that expensive when you add in the higher priced wideband tuner, which is not only a wideband meter, but also a datalogger (a feature the flash does not offer), and MAP capabilities (something the flash does not offer).

I do not think the flash is a ripoff at all - I had one in my car, and enjoyed it. But I do not think it is worthwhile to go back and forth via mailorder, unless you have the most basic of mods (intake, exhaust, no headers). I am a firm believer in having an ecu solution tuned FOR your car ON your car, and this is just something the flash cannot offer, as it is extremely cost prohibitive. The flash is widely used in other communities (Evo), as it is FAR more affordable, and there are tons of tuners offering it. For the Z community though, the UTEC will be the way to go
