Uprev Tuning Info
 

OK, after a search, I have found nothing in the tune section about self tuning. I have the softwere installed and can change parameters. Am I the only person with the Uprev Tuner Software? I would like to start a ROM share thread; what works and what dosen't. Please shoot me a PM if you are self tuning.

I was just thinking the same thing. Just had the car tuned and wanted to learn how I can enhance it with street tuning and data logging. Maybe we can get some people here with some uprev tuning experience.

If you have the tuner Ver open your Rom editor and load your Rom. That what all you can change.

Sample of mine

OK, I uploaded a new tune today based on lean cruse/increased ignition timing. Results are very positive. 24.2 MPG before and 26.3 now. Indicated by onboard AVG fuel over a 100 mile city/hwy course. I will gather more data during the week and then post the ROM for referance.

Car runs just as before during accel, during lean cruse conditions the new map pulls fuel and adds timing.

Other changed made are
Removed top speed limit, I have no idea why but I did
Disabled codes to aft O2 sensors
Raised Redline to 7800 and the fuel cut restore points as well

Is there a table for the brake over ride switch, Switch that will not let the car rev past 2k with you foot on the brake( AUTO).

I did not see one but It could be the cruse control interlock. If that is the case, you could try the ETC to off. See below


"ETC on/off: This setting disables the torque management aspects of the electronic throttle control. Turning this setting off will have the effect of making the throttle linier. The ECU will try to run the throttle plate % at whatever the accelerator % is.
** ETC on/off tuning tips: Turning this setting off will also disable the cruise control. Most of the feedback about disabling this setting is that the throttle is far too touchy, even for race drivers. Chances are you will never turn it off, but it is there if you’d like to try."

You could disable the switch but if you hit the brakes (cruse on) your cruse control would add power "VERY BAD"

Someone with an auto should know the answer....

Thanx man I will have him try that also. have never used cruse control anyway. LOL

I can't post the ROM file because of size limits. Shiit me your email if you want my current ROm file.

:eek:

Just a quick comment -- those of you looking to self tune, do you know some good basics on tuning fuel injected cars in general?

If not -- start with this: Amazon.com: Engine Management: Advanced Tuning (9781932494426): Greg Banish: Books

Really, really good book that walks you through it, theory and application step by step.

That, plus the uprev guides will be invaluable.

Current tune

Map 1 has almost 500 miles of testing
Maps 2, 3 are still under development
Map 4 is the stock map for referance

Timing is +2 units on all maps

Fuel is 93
Alt is below 300 Ft
Air Temp is 75 to 95

Mods to car (engine)
Injen CAI
Gemini Exhaust
HFC Invidia

What differences are you seeing per map vs stock fuel mapping?

Stock is the #4 map. You can't look at the colors you have to look at the numbers.

Haha sorry, I should have worded my question more efficiently. With Maps 1,2, and 3 what performance differences are you seeing vs stock. I know you mentioned earlier better fuel consumption. Also have you noticed any differences in drivability?

I have not had access to a dyno or closed course yet to test preformance increase with the maps. But I can say that just smoothing the AF curves and bumping the timming up have made the car a much better for throttle response, Power delivery seems smoother as well. All measurement taken with *** dyno on real world driving.

MPG is up 1.5/.8 MPG Hwy/City with map 1.

Sweet. Ill plug your numbers in my tune tomorrow and test it out. I found a tune that changed the throttle map on here a few months ago and that allowed more throttle at low speeds (presumably 100% throttle). I can try to post it here as well if you want.

Yes Please. I can't beleave there is not more of this at this site. We need to contact an administrator to allow the ROM's to me posted.

Ok I'll see if I can't get it posted later tonight or early tomorrow.

Sorry it took a little while. Here is my throttle map. Credit however is given to wstar and I found this information in this thread:

You can copy this straight from here and paste it into a throttle table in UpRev:

From the butt dyno it seems that the car has a whole lot more umph at lower speeds. There isnt a real jarring jump when you fully press the throttle as it comes on very smoothly. IMO its much better that the stock throttle settings.

Thanks, FYI, fuel table 3 is showing 27MPG HWY, at 65-70 MPH with the cruse control locked. 2 way 100 mile course. Air temp is 78-97, and the RE-11's are much higher than stock due to larger size and compounds. Seems to take VVEL a few (50 miles) to learn.

With map 3 how does the car feel? Throttle response and power delivery. I havent had the chance to change it up yet for my self. Hopefully Ill get around to it tomorrow morning lol.

The map is smooth. My cruse control did drop off line tonight. I did not notice any change in power at the top end of the af MAP. Tuning for max power is just some controled runs on a dyno/closed course. The DD part of the MAP will require many days and miles of testing.

I beleave all the dyno tunes are just max tunes and then smooth the transitions from the lean to the new max power AF's. Thats all you have time for unless you rent a dyno for a day.

I will have months of data and thousands of miles in my finished tune.

***Also added 2 more units of timing (4 total) accross the timing table along with fuel map 3 and the improved throttle map. All seems well 28 to 29 MPG cruse at 65-70 and still rocks when I get on it.***

Returt trip was 27 MPG, air temp was 20 degrees cooler.

You guys got me wondering about the ETC off function. I may do it while I am @ Zerolift. I think that will be either epic or epic fail for me. I think I can live without VDC, SRM, and Cruise (except I will be complaining on the drive to Baltimore and back).

In for results :tup:

All I have seen ETC off is bad. But you can try it.

I tried it and didn't notice much of a difference. I may just be crazy lol.

The map above from wstar is that his latest one. I'm making some changes in about a hour and was going to see what my maps looked like compared to his.

What idle rpm are you guys set at?

So everything went smooth Saturday, the car is a dfferent animal again? I actual started a thread on myg37 about the ECU's relean with a tune. We reflashed the car and made some small changes to TQ management, timing( Added) and fuel( took some way) but the car literal screws now off the line, Hit it few times over the weekend from a dig and you could actualy feel the car twist a bit, even the wife was like WHOA did we slid or something, LOL . Just seems so different now.. BTW the fans speed is AWESOME, U usually see 200 oil temps and 185 tranny temps, We adj the temp to 185 fans start to come on and I saw nothing above 185 oil and 165 Tranny. Idle not sure man sorry but looks like 950? If I remember right. 7SPD auto BTW

Usually 750 RPM idle.

I reset the cold temps to lower RPM's, reound 1100-900 I think, but 750 at 40c.

That would be amazing!

I want to do some data logging on my normal commute to check my tune. Can someone tell me what the are the most important parameters to log? When I load Cipher there is a long list and I am not sure which ones are the most important to track.

Although it's pretty risky, it'll be nice to be able to share throttle tables just to get back the snappy response of the 350Z. I don't care how much power the car make, which already pulls hard to redline. For daily driving, even the Xterra has more grunt.

IIRC, it's tuned for autos so I'm not sure what it'll do for 6MT.

Should work fine, haven't tried it personally but the throttle table is independent of the trans type, I know the stock tables look exactly the same so it recons that the tuned table would be the same. The Z33 throttle tables are identical between auto and manuals as well (stock and tuned)

Works fine in my MT6!!

O rly? :excited:
Were you able to achieve 100% throttle as well? When my car gets tuned, I'm definitely going to try to add in these tweaks. Can you set these throttle values to one of the maps? That way I can keep this stock table for rainy/winter driving, and switch to the next map. It'll be like having sport mode!

I can only imagine what this map + turbos is going to be like, but I'm all for improved low end response for daily driving.

Is the table based off the one dragonbreath posted? I'm several months away from tuning anyhow... need to switch over to external wastegates, 3" down pipes, and 3" exhaust first.
