How to find out if your car is tuned?
 

This may be a very odd question but when i bought my Z i bought it from an auction and i didnt meet or talk to the previous owner.. i have never driven any other Z. My Z has quite a few mods and from what i think is with these mods you would need a tune.. My question is, is there a way to find out if my car is tuned or not?

You could try to change maps if it's using uprev. Press and hold cruise control button while flicking up or down on accel/res

hmmm ok now how would i know if maps are changing also.. my cruise control doesnt work. the cruise light comes on in dash but does not hold the speed so if my cruise control doesnt work would this still affect trying to go through maps???

From another thread.

How does map switching work?
Using the Cruise Control Buttons...
-Hold the set/coast toggle down
-Press "Cancel" once for map 1, twice for map 2, etc...
-Then release the set/coast toggle.
-When you release the toggle, the cruise "SET" light on the dash will blink once for map 1, twice for map 2, etc...

Does it work the same way with EcuTek or is that still just a one map system? I forget where they are with that software A) cuz I don't have it and B) because they made a bunch of promises up front and took forever to start delivering:rofl2:

Tried it on mine and it did nothing and my cruise control works fine! I'm not tuned, but just wanted to see how it works.

hmm thank you! ill definitely give this a try.

Hold cruise control cancel button down for a second and the tach needle will jump to 1000 rpm for map 1, 2000 rpm for map 2, etc., showing you the map that is currently being used. You can then use the accel/coast switch to toggle between maps. I've got four maps with EcuTek at the moment, plus valet mode.

UpRev and EcuTek are the most popular tuning options so one of the methods given above should work.

Another, more complicated, way to tell is to look at some of the tables that tuners change from factory settings. If you see some non-OEM numbers, you have a tune.

If all else fails, contact UpRev and EcuTek. IIRC, the tune is paired to the unique ECU in the car and they may have records.

Edit: Or go to a smog check place. They can usually tell if the ECU has been changed and exhaust gases will probably be out of spec.

Ok so i gave this a try and it worked. The cruise light blinked once all the way 5 so this means my car is uprev tuned??

your cruise light didn't blink at all?? mine did so if yours didnt im guessing mine is tuned..

I assume so because mine did nothing at all and i tried it about 5 times.

The best way to know it is to search what the majority of tuner shop set their Valet Map or Security Map to...

MAP4 ? RPM bounces back and Forth above 3K RPM etc.
MAP5 ? Car will not start.

Done! Problem solved!
Some car like mine does not show any blinking light at all when I switch map. That is the reason why Seymore4 designed my MAP2 as valet. I was not sure if I was switching maps back then, so I would check MAP2 -valet to make sure I am changing it.

BTW, eventhough I have Uprev, I could still use my cruise control and it's full features.

i will be putting my Z on the road tomorrow so ill be able to play around with the maps, that way i can figure out what is what. also i believe there is something wrong with my clockspring i explained what was going on with my cruise control to a friend that works at a local shop and he thinks there could be somthing wrong with the clockspring.

your cruise control does not work because the tuner turned off ur ETC(electronic throttle control) due to this the actual cruse control cannot set ur throttle by map, cuz its OFF. Although ur probably asking "well if its OFF how do i still press gas and drive?" well the ETC turns off the map not the actual throttle, the throttle it self is now 0-100% depends on how far u press where be4 it was nurfed like -100 to 34,000(-1-92%) as an example.

also the maps r unknown example:

map1 might be regular driving
map2 racing
map3 valet rpm topped @3k rpm
map4 does not start car, could be a map as a secondary anti-theft
map5 stock


these r just speculations, but ppl do this.

So I've been meaning to check this on my car for awhile and finally did today when I got home, in neutral in the garage. Bought the car last december. I tried the ecuteck instructions first, nothing. Then the uprev instructions and it blinks back. Cruise control blinks back how many times I clicked cancel so I'm assuming I'm tuned with uprev. Cruise control has worked fine. Now I'm worried because I don't know what map I was in and don't want to put it into a map that might hurt something. Do I have anything to worry about? From researching it looks like the most common maping is:

1: Tuned Map for 91 Octane
2: Tuned Map for Higher Octane
3: Valet
4: Anti-Theft
5: Factory Maps

Is there a way to verify if this is my setup? What else should I know? Also I bought the car in Florida and brought it to utah, would the tune not be as good now? I've been very happy with the power and performance of the car, hope I don't f that up now lol. Thoughts?

Every tuner is different on how they set the maps up. My tuner can tune for power and gas mileage in the same map so he only tunes one performance map, a valet map and then always leave map 5 as the stock map. That's for NA tunes.

FI is completely different

Did you try every Maps? Did one of the 5Maps bounces back and forth at 3K rpm? Try reving the RPM past 3K on every Map and see if at least one will do it.(Valet)
Then as you test each Map, see if you"ll come across with no start(Anti-theft)

If still not convinced, meet one of our members (there is got to be at least one)
that is closer to you with Uprev cable. Hooked it up to your PC and OBD2 and see! :happydance:

Thank you... I tried 1,2,3 and visually verified that it blinked back. Then I got nervous and turned it off. I can go out and check through all 5. Can I hurt anything by being in a race map without higher than 91 octane? I'm excited it's tuned but would love to know which maps are what. If I called uprev with my Vin could they tell me?

How to find out if your car is tuned?
 

If the cable used is a standard cable then you can't open the rom editor and see what the maps are. Also if the tune is locked then you won't be able to see anything either.

The only thing you can check is the rpms. If the rpms were set higher than stock then you should notice a difference between the stock map and the tuned map. Most tuners use map 5 as the stock map. Check idle rpms with that one and then cycle the other maps. To be extra save run the stock map until you can get it to a professional.

The best way would be to find a local UpRev tuner and have them look.

Okay so i went back to the garage...2 is valet, 5 is anti theft...not sure on 1, 3, 4. 4 seems to make the car more aggressive. I just reved in neutral and the engine seemed to flex more and have more power. Reved to 4-5k. Guessing I shouldn't drive to find out on those 3? I have no idea which map I've been driving on lol

Maps 1,3,4 all idle at 600 or so rpms. No difference in neutral moving between maps. Closest tuner is probably in slc a few hours north. Now I'm nervous to drive her lol

You could buy an UpRev cable, remove the tune file and when you get a chance to get to a tuner have him tune it for your location, local octane and mods. You won't lose the license. It'll just return you to the stock tune.

Base idle RPM is universal setting. All Map will be the same idle RPM.
The good thing is you only have 3 Maps to worry about. :tup:
I would definitely check it with the Uprev pro tuner closer to you to check how these Maps were tuned. Car should be not a problem to drive, just do not red line it . I would not trust the tune 99% as of now since we do not have any idea how they tuned it or what parameters changed. Normal driving should be fine at all on those 3 Maps. Avoid WOT(flooring the pedal) we are not sure yet if AIr/fuel ratio is dialed in on WOT run.

BTW, buy a lottery since how often you get free Uprev license? =)

As Jwick mentioned, you can also buy an Uprev cable and flash the car back to stock, your Uprev license will pair to your cable. I can ask my tuner to give you a back to stock file. Regardless of tune file being locked by your tuner, I believe flashing back to stock will overide everything. When you are ready to see a Pro Uprev Tuner, just bring your cable (w/ Uprev license paired) and he can take a look at your MAPs or create one (pay for dyno hours)

Or

Buy a cable, flash it back to stock and Use Seymore4 to Etune your car. You have to email him your data log.

Right now we do not know your ECu serial number. You have to call Infiniti parts dept. to get that. They will ask for your Cars VIN#


Write down your ECU serial number since tuner needs that to get you s base ROM and back to stock map.

Are you saying the the idle setting is independent of map and if the idle is changed its outside the individual maps and they will all be the same regardless of its set to 500 or 1200?

The idle setting is Universal , just like the ETC 0ff for Electronic Throttle Control.
Once you set the base idle at certain RPM, all MAPs will have the same. I have a tuner version and I had that idle RPM change more than a couple of times. I still prefer 775RPM.

I appreciate the response thank you. I wish I knew what map I was in before today. It drove fine through redline. how much would a cable cost me?

PM seymore4 and see if he can get you one. He is an active member here. He also does Etuning.

That's good info. Was not aware of that

Check UpRevs site but if I recall its $225

so in order to put my cruise control on i would have to go to a pro tuner and have them mess with it?

Im in the same situation you are in.

I would be very concerned. Florida has 93 octane and it's at sea level. You're at altitude on 91. You've got to be running lean. Go make a pull on a dyno and see what the sniffer says your AFR is.

The higher the altitude the lower octane required. I'm at over 5300ft and 91 should be fine here. I will get it to a dyno soon though and see what each Map looks like a determine if I need a re-tune

Funny cause we have the same car. Talked to uprev today and they said either buy a cable from them with a map or go to a pro tuner...license is there so only dyno time/tune would be an expense. pretty cool. I haven't driven again yet as the weather is bad today and tomorrow. I think I'll try the 3 Maps and see if I can tell any diference. What are you going to do?

Altitude has less air. Cars pop rich up here.

Yup we're about the same altitude... it was 75 degrees today and now it's snowing outside right now ha ha. Good times

I was thinking of calling a local uprev pro tuner and see what he suggested. I was thinking of getting the cable and just have them dyno/re tune. i live in Massachusetts and i bought the car from an auction in Dallas Texas. Your lucky you could figure out what 2 of your maps were, i don't have a valet or an anti theft map... so im kinda screwed.

So you have 5 maps but no valet or ani-theft? That sucks. Did you just guess and keep driving? Notice any difference? I haven't driven mine yet. If you are going to a tuner you won't need the cable. Save the money. Guy at uprev said put it in map 1 if you dont know cause thats usually the tuned map and its better than guessing and getting an aggresive map instead. It will be two weeks before I can get to a tuner here as its 3 hours north but I'll let you know what I find out and if I re-tune or not.

it does, i have been driving on map 1 and the car runs fine, like normal i guess. i have yet to call a local tuner.. and the closest one to me is an hour an half away.
