Tuning Questions

[bejjutsu]

Hi All,

There is a lot of talk about Uprev Tuning on the forum, as well as some other methods of tuning.
The official Uprev site is a little light on details, as are most of the threads.

*Most* of us have the 06 M35X, so if you're familiar with this, it would be helpful to offer up the following:

1. What does it do, what should it cost?

2. What are the benefits (performance, MPG above 20 combined, etc)?

3. What are the drawbacks (decreased engine life, lower MPG, voiding a warranty, increased maintenance costs, etc)* *these are pure conjecture

Thanks

1. What does it do, what should it cost?

Cost: Seymore4 is going to be your best bet price wise
What it does: alters fuel mapping and throttle angle primarily. Ignition timing, shift firmness are two of the "big" other values that can be altered.

2. What are the benefits (performance, MPG above 20 combined, etc)?

"Instant" response from throttle. Better drivability due to better fuel mapping. Multiple maps (5) -- I use performance, economy, stock, anti theft, and valet

3. What are the drawbacks (decreased engine life, lower MPG, voiding a warranty, increased maintenance costs, etc)* *these are pure conjecture

Zero, and I mean absolutely zero.


You need to do this especially if you have any mods. You would mod a suit if you lost some weight or grew a bit right? Same with the engine's computer.

+1 on everything Dean said, then here's my own little bit:

There is nothing on the market that can compare with Uprev for an M.

Uprev is an ecu reflash that allows us to completely reprogram how the ecu runs the car. It is 100% non-invasive (no cutting wires, etc) and you access it with uprev's proprietary USB-OBD2 cable. It is also completely reversible and you can remove it whenever you want, returning the car to completely stock condition.

It allows us to:
1) reprogram the electronic throttle to eliminate the throttle restriction
2) fully tune the fuel targets and delivery to optimize power and efficiency
3) program 5 maps independently that you switch between using the cruise control buttons--handy for anti-theft and valet maps

4) permanently disable any CEL that come on from exhaust mods --HFC, test pipes, or headers
5) adjust ignition timing, although this is an over hyped feature that rarely does any good on stock engines
6) adjust the torque management tables for firmer shifts
etc etc etc

Provided its properly tuned, there are absolutely no downsides. Your engine will be running better with less stress on the internal components so it should last longer and run stronger over its life.

I know a bit about this, shoot me a PM if you want to try it out

I'm UpRev'ed and had no idea about number 4 lol. Good to know. That means I can pass inspections for ever now (they don't do a tailpipe sniffer - they just plug into OBDII here in NY). lol.

These guys are dead on with the UpRev. If you have any modifications what so ever to your car, you need to look at getting a tune, period. We dyno tuned our G35 with very minor bolt-ons and the difference was night and day. You can see for yourself here:Reality of A Dyno Tune. We are also a UpRev Dealer, so if you have any more questions ask away.

subcribed! - seymore4, i will contact you as soon as i'm done with my maintenance chores on the car

Make sure you do spark plugs, VQ's like to eat them up And if you're going to be tuning it one step colder, NGK LFR6AIX-11 are great

Thanks all, for the the posts. MUCH appreciated.

Here's a bonehead question that may be of help to others unfamiliar with tuning: What if you switch the map to "under 30MPH" while on the highway? I assume there are protections for that?

Seymore- thanks for your PM. I'll get back to you tomorrow late AM. Thanks!

[RED_DET]

You would have to go through a sequence in order to switch the maps. If that happened, it would be no accident.

Your car would simply bog down and coast/ engine brake till you reached 30mph... at which point it would come back to life. Won't blow up your engine or anything, but you may need to change your underwear afterwards You can always disengage it by switching back to a map that is not limited to 30mph

You would have to go through a sequence in order to switch the maps. If that happened, it would be no accident.

Its actually quite easy to do if you're not paying attention. Considering most people don't switch maps daily and the sequence you have to press with the cruise control buttons is kind of awkward at first. I could see someone attempting to switch into an economy map on the freeway and mistaking the order of their maps quite easily. Not to mention the fact that Uprev has had some trouble getting the cruise control light on the dash to blink and confirm which map you're on with some of the M roms

[RED_DET]

Why not just stop the car, switch to the map you want and carry on.... ?

I have an 07 M35X. I know there is a harder time finding dynos that are for all wheel drive. I am curious though, What do you charge for a Dyno and UpRev ? Also, what do you think about the motordyne thing (I cant remember the name of it. It is said to increase power throughout the power band)

Are you thinking about a plenum spacer? Several companies make them, and yes its pretty much the best mod for a VQ35DE.

Dyno tuning will range from $550-800 depending on the shop and region, that includes the Osiris license and dyno time, but not the uprev cable. Especially since you're AWD and most uprev protuners only have 2WD dynos I would recommend picking up the cable and getting it done via etunes (you datalog and have updates sent via email), you can get that including tuning for as low as $450, and the tune will be 95% as good. Also you own the cable so you can reflash back to stock and use it on a different vehicle, sell it used, etc. later on.

The motordyne product you speak of is probably the plenum spacer. The 5/16" basic plenum spacer is used on our G35 and it will add 10hp over stock. There are multiple dyno's out there that show those increases. Probably the best bang for your buck at this point.

Unfortunately we don't have access to an AWD dyno, but for price comparison, the cost is $175/hr for RWD dyno tuning, which is needed for the UpRev Osiris Tuner. On average an UpRev Dyno tune will take 2 hours. The license fee for the Osiris Tuner is $300 plus the dyno tune. If you want a Tuner cable, then we can work something out on the price. The UpRev Osiris Standard doesn't require any dyno tuning. Your are emailed a E-tune based on your modifications and the cost of E-tunes is $50 each time. The Osiris Standard cable is $450 shipped. If you are interested in a cable, contact via PM and we will work out something.

Im from Milwaukee Wisconsin I have a 2008 Infiniti g35 with typhoon intakes for mods going to do the cats next but after I wanna get it tuned don't know where to go? I wanna do the osiris tune so if anyone know please help me thanks

Go to Uprev's site and find a tuner near you. They have a list.

Also, you're posting in the wrong section. This is the Infiniti M section, not the Infiniti G section.

This isn't exactly an M specific topic..
