Canned tune--- Bully Dog tuner
 

Whats up!

I just wanted to ask Z owner's opinion on boxed tunes. I just purchased the triple bully dog gt tuner yesterday. I called and verified with bully it would work. Ive used one before on a 2009 Altima Coupe. I installed it after header, cat delete, cat back, intake, and stillen pulley. It made it run smoother. I just dont know how well it works with the Z, im asking just in case one of you guys have used it before and had good or bad results. The altima was smoother AFR 12.3- 13.5. They claim 10-15 hp ( up to 20 hp on premium tune- LOL.) I say 5- 10 whp). All I have done to the Z is test pipes. Im just looking to run low 13's in tue quater. Thanks in advance for any and all input.

370z is not on their application chart....... Now, I'm not too sure if they were assuming 350z and 370z are same cars or not.
I'd try to confirm that again with them.

Concentrating on a good 60 ft time would probably get you there as is. On average, a stock 370 should trap 103 mph. Test pipes should get you 1.5-2 mph. At 104-105 mph, you should be in the low 13s with a sub 2.0 60 ft.

I was one of their "beta-testers" signed up like 2 years ago and got an email a year later from them. Tested it for a few months last year and it was decent. Got rid of some of the drive-by-wire lag and it "felt" like it pulled a little harder. Also it was a decent device for monitoring things (could read A/F from OBD2). However they never asked me to get on a dyno or anything like that so not sure where they are getting their numbers from.

After having the device for a few weeks I sent them some feedback etc.. and never heard from them again. After installing the SC I don't really have a use for it in the Z, so its going to go in the Cube.. That 1.8L needs all the help it can get.

thanks
 

Thank you.
I got it yesterday, I got one of the guys to overnight it for free. I did everything step by step but it still didnt work it gave me an error code and told me to update or call bully. I called and they told me I had to wait till next wednesday for the new update. Ive seen some claims on the internet that the Z is good for 13.7 and some as fast as 13.3. I know how to drive decent, but Im no professional by any means. I just want 13.0-13.4. For example two weeks ago a buddy took his 2011 stang 5.0 to the track and pulled a couple 15's, 1- 14, and the 13.6 was his fastest. I cant vouche for his driving or how hard is to put the power down on a that car. But the car is way better than that according to specs. Now is the waiting game but. Ill let you guys know.

m4a1mustang on the forum also has the 5.0 Mustang and I believe he ran 12's at the track. I'm heading out to the drag strip for the first time this weekend (if it doesn't rain) and I'm hoping for low 13's as well with a stock 7AT.

I'm pure stock 2009 7at and on my first 1/4 mile I did 13.35 @ 105.6 mph, that's with a horrible 60 ft, try launching between 1400-1700 rpm, seems to work best

thanks i'll try it.
 

Ive launched my car only 2 times since I got 3 weeks ago. Both times at 1500 the first one was a heck of a launch the second it just fell on its face. I think i let the clutch out too fast. Im going to try it couple hundred higher and easy on the clutch. How much abuse can the stock clutch take though?

like to see a dyno pre and post install - even better some logs.....

I'm definitely interested in a tune that gets rid of the throttle lag, w/o tweaking the scaling on the throttle pedal. Does anyone know if the uprev tuners can do the same?

the stock clutch can take plenty of abuse. I had about 100+ track launches on mine when I pulled it out. And I usually launch at 4000 to 4500 rpm. and for what it's worth it had about 26k miles on it when i pulled it out.

I still have that stock clutch too, sitting in storage. Jnaut (who did the install of my 2010 clutch and jwt flywheel) said it looked still pretty good. and it also drove pretty well when i replaced it.

:iagree:

Is this any different from the Cobb Accessport that was available for the Z before they stopped making it? The hypertech pocket tuner also falls into this category too, I believe. Any thoughts on which is better/more effective?

Also, OP how does the car feel after using the bully dog? Have you noticed any difference?

Sounds exactly like the hypertech pocket tuner.

Honestly, unless you can actually change parameters (i.e., actually use it to tune!) it's not really worth it.

I see it on sale for as low as >$120. I fyou can get it for that low a price, it's probably not a bad deal for the money, but definitely not as good as a custom tune.

I finally got the bully dog tuner installed yesterday. From my personal experience the car pulls significantly harder specially from 2nd gear on up. The pedal can be adjusted to normal, economy, performance, or extreme. I put mine on extreme and it got rid of ALL the pedal lag Im relearning to drive the car by how much gas to give it in every gear change. The only thing I kinda dont like is under normal driving ( crusing) I need to through the gears alot quicker since it revs twice as fast. In a blink of an eye its already at 2300-2500 rpm. The timing can be advanced or retarded. I can also mess with the afr but I didnt. Because I know Nothing about tuning. With the performance tune installed according to the tuner which its getting its info from the ecm through the OBD connection under WOT it read between 11.9-12.1 in the afr. The timing was all over the place I dont know anything about timing. Also I dont know how accurate or reliable those number are. I wanted to take it to do some dyno pulls this Wednesday but im not going to be able to. I got my z impounded on sat night and a few tickets and that set be back a lot. : (... I wont be able to until next payday, 2 wks. yeah I talk to guys at bully dog and while i was on the phone he asked the tech and the tech said the increase for the z was 6% in hp and in torque it was 9- 10% increase at wheels. On the dyno he said. Hey those numbers arent bad, If they're true. I can only pass on the hp and tq numbers I was told. untill I get it to the dyno myself.

When you say it has different pedal settings, does it change the delay or how sensitive the pedal is to movement?

Yes, what it does it changes the sensitivity of the pedal. the car reacts faster to when you touch the pedal. To me it has no delay and more sensitive . Others would say, very little delay and more sensitive.

So what you're saying is that you'd be at 100% throttle before the pedal hits the floor?

pedal sensitivity
 

No not exactly. I dont know if you've ever noticed when lets say, you are in 3rd @ 30 mph and you decide to punch it, its not going to go very fast cause of the gear. Besides that when you hit the gas it literally takes a sencond process how much gas you just gave it. (lag ). I dont know where the change took place at the pedals voltage, just ecm, throttle bodies or all of it. It processes faster like on a pc going from a duo 2.0ghz to a quad 3.0 ghz processor. Lol. reacts faster to how much gas your giving it. It wont give it more acceleration than what you are asking at the pedal. But the process time it takes from when you hit the gas to when the car reacts is quicker. Thats all.

Cool, that's exactly what I wanted to know. Thanks!

So does this also take off rev limit, top speed, neutral rev? I called bully and they were less than helpful. The guy said it was for any car it would just read an error and need an update. So it it not specific to our cars or does it read/learn? He also said it was a downloaded program and not a live feed from the box. This is contrary to what I've heard before. Any thoughts?

When I had it, the rev limiter setting didn't seem to work, reported it to them and never got a response. Didn't get a chance to test the speed limiter...

I'm not concerned with speed, but more the throttle lag. I talked to them again and they informed me it's a generic tune. It's just a "Nissan" tune. I'm gonna avoid it. It looks great, but I doubt there are any performance gains...

Can someone confirm if the Uprev tunners can take care of the throttle lag issue??

I agree with you, I've called bully multiple times myself and some of the guys are real cocks. They have attitude and they tend to give a I dont give a rats @$$ attitude. But Ill answer couple of the your questions. It does not eliminate the neutral rev. It does allow you to change the top speed up to 180 mph. It also allows to change the red line. I have mine at 7850 I just did it for the heck of it Im not sure if it lets you go up any higher. Ill check on that. No its not specifically for nissan 370 it works for lots of other gas cars but when you select your vehicle it downloads the tune specifically for the Z and nothing else and marries your vin and verifies its a Z. When I got it I selected the car then updated. thats when it got the new files for the nissan. I dont know exactly what is live feed is but I think this one is like they said, its just a cheap tune that their nissan tech put together and you get whats there. You can change a few things and but they are also limited to how much you can change it. It does read your stock files and saves them to sd card and dowloads one of the tunes (whichever you chose). Im not trying to convince anyone although it might sound like. Ive had two and I can say it does change the vehicle it thinks it cleans up the table. now power gains I cant promise anything. I dont work for bully. Ill be going to the dyno next week and post pics and maybe a vid. So we all can find out if I just wasted couple hundred of dollars. Lol! Uprev i had never heard of it or know how it works Ive heard all kinds of good things and a few bad like everything else. Can uprev be completely removed for warranty purposes? Or is it like Trifecta we need to have the cable in order to remove it? Does it void warranty? I know nissan does with the bully dog. But it can be removed in matter of 3-5 minutes, but if nissan sits down for a for a few hours I know for a fact they will find that the computer was accesed without authorization. Easy removal and past experinces is what sold me thats it. Sorry for the long post.

You will not see 10-15 hp gains.

Bully Dog
 

Looking forward to your dyno results. By the way, what was the price?

Also, how would Nissan service dept. know that the stock settings were changed if the stock settings were reinstalled from the SD card?

I payed $300 bucks. if i get 5-8 hp out of it im more than happy. I dont really know how exactly Nissan woukd find out but if they dig into the the computer they will. I think the only reason they would dig into is if big repairs are needed- powertrain and I have history with Nissan with blowin up an 4k mile engine. Lol. My guess would be because the bully is not a nissan authorized tool. I guess and the computer takes note of it somehow saying it was accessed by tool # so and so. I dont know but bully even admited to it. Im going to try for wednesday $40, cause is dyno day. Here in okc its expensive 75 for two pulls anyother day.

OKC Z,

Do you have a 7AT? Does it smooth up the shift points so it's not grabbing for gears at low speeds? How's the throttle delay? These are the two things I'm concerned about. 5hp won't change my life.

No mine is manual tranny so no changes there. To ME personally throttle response was noticeably improved. As far the 5hp im just trying to be humble and keep my expectations low that way I wont be disappointed Too bad. Lol. You know what I mean?

here is the results, IMO im not very impressed.

Bone stock car I dyno at 256hp and 218 tq at Abel Racing in midwest city Oklahoma. I went back today this time the two mods I have done ar TS test pipes and the Bully dog Gt tuner. Before the guy ran it he said "what are we hoping for 260" I said 240 be good. We got 278.6. Here is a link to the video I took.

YouTube - 2009 Nissan 370Z Dyno

I'm guessing about 15 of that 22.6 hp gain was due to the test pipes.

The graph. How do some people here on forum get in the 270's with 0 mods? Nissan 370Z Forum - OKC Z's Album: OKC Monterey Blue Z - Picture

I will buy the programmer off you if you're not satisfied with it. I'm willing to give it a try!
