Interest Thread for Triple dog GT GAS tuner

[DaCoupe]

I don't know why but 20hp seems a little too optimistic lol

well considering the 3.5 gets 35 hp, half of that is 17.5, and the 2.5 would probably get atleast more than half so 20 hp seems like a good number

What is going to cause this hp increase?

20 hp would be huge, i doubt that is possible.

This is great, but will we actually see power gains? Will this work as the ECU tune from Technosquare or Greddy Emanage for the 3rd gen's?

I guess my question is, WILL IT ACTUALLY DO SOMETHING? IIRC someone tested the power pup and it did nothing to his 3.5SE?

How can this work for all Altima's from 02-09, the ODB port changed in 05-06 and its completely different for 07-09..

Hrmmm....

I don;t think there is a WOT limiter on our engines, it was for Torque Managment on the Titan IIRC.

it doesn't work for the altimas before 05. only for 05-09. check the PDF in the OP post.

there is a wot limiter. it's been verified. before our only option for that was the BLITZ Throttle Controller but that thing costed as much as this and only did that.

[Dexion]

I thought it was actually verified that there was NO WOT throttle restrictions (past a certain RPM of course) Someone has a Consult III and recorded the voltage of the throttle switch and it was constant, it never had a change.

The 3rd gen's have a throttle restriction and thats well known. If you mean the throttle closes by itself on you after 6600 RPM then thats different, that is there to protect the engine. Instead of bouncing off the rev limiter the car kindly takes your foot off the accelerator pedal

[LinkNuc]

I also am pretty sure that the WOT limiter that the bully dog removes is ONLY on the Titan, I don't think the 4th gen Alti's have such a thing...or should I say the same thing as the Titan.

yeah I mean this lol

SO is this ever going to release or is the gas pup all we get?

[deebo422]

I'm definetly interested!!!! In for a GB!

Any updates on this???

Deebo, go here http://forums.altimas.org/zero...m-est and look at the new price for the tuner. You missed out on the $307 price from yesterday, but they are still having the "30 off" promo that mcheddadi originally posted about and it's $317. BUT it ends TODAY!! 7/7 @ 6pm est. So if you are even thinking about this, I'd get it now if i was you.

Also, in that thread, Robert(maybe you can convince him to let you get it for the 10% off, seems like a good enough guy to let you do it ) from truckaddons.com, is trying to get us a definite date on when bullydog will release this product and it's suppose to be in a week or so.

[deebo422]

Damnnn I missed that nice offer!!! So they aren't out yet? So basically if i buy i would be pre-ordering......

You are correct sir. But I think it's going to be worth it

[Sentientbydesign]

Hola Peeps. I thought I'd chime in like the guys from Stillen did with a few "thoughts" to ponder.

First of all, I am extremely leary of the 35 whp claims. It's possible that the Titan was detuned from the factory for a reason (fuel economy, emissions...etc). I can almost guarantee that the 2.5 and 3.5 won't see 35 hp.

5-10 is realistic. 15 would probably be tops.

As for dynoing a CVT... The most accurate way to get numbers off of the CVT would be to monitor the "gear ratios" through the run - I'm sure the ECU or TCM monitors this, just not sure how to extract the data. Taking that data and recomputing the HP based on the corresponding TQ for that RPM would give accurate HP numbers.

It's very likely, however, that the HP graph would be extremely wavy as the CVT logic adjusts for the TQ load on the transmission.

Furthermore, many CVT owners would probably not be happy seeing their max whp because the CVT logic seems more deeply rooted in fuel economy than in performance.

What does that all mean? It means that there is a way to pull accurate HP numbers, but if the CVT modifies the gear ratios at a different rate on one dyno run from another, you won't be able to compare specific gains across the RPM band.

Would be nice if Nissan put out a "Test Tune" for the CVT controller (TCM) that allowed for specific steps or to hold a ratio through the RPM band.

Also, my independent "tests" on my last car (96 I30) yielded that WOT at low RPMS was slower than partial throttle, then WOT at high RPMs. This may seem counter-intuitive to some, and to other it may make complete sense. In any event, if the throttle has a low RPM limiter, it can probably be tuned for better acceleration, but we shouldn't confuse that with WOT at low RPMs.

[Sentientbydesign]

One more thing...

Comparing VQs is just a joke. And NO, I'm not trying to offend anyone...

I was talking to a car sales person the other day about the VQ30DE in the older Maximas/I30s and he made some very true statements. Those engines were diehard.

The VQ35DE and VQ35HR with their different variants may be in the same family of engines, but they aren't all comparable. I very much doubt that the VQ35DE (Rev-up) in my G35 will last the 280k miles that the VQ30DE in my I30 did (car is still running to my knowledge).

So we have the following:VQ35DE FWD (which always seems detuned or has different internals)VQ35DE RWD - Higher tuning in most situations or different internals which explains the HP number variations since 2002.VQ35DE Rev-up- Beefed up internals, more agressive tune, variable exhaust timing, higher redline.VQ35HR - Even more beefed up internals, better intake/exhaust timing, even higher redline, symetrical intake design.

[Dexion]

Alot of power can be gained from just leaning out the fuel mixture a bit since the stock ECU makes it rich if you add boltons to the car.

Since this VQ's power does not fall off raising the rev limiter to at least 7100 RPM's would be plenty to take advantage of the sweet spot in our power bands.

The VQ35DE's in the 2007 and up Altima's have newer parts as well. For one the heads are directly from the VQ35HR in the 350z (07-08)

I personally wouldn't raise my redline unless I knew that my internals could handle it

As for leaning out the A/F...I did a dyno run last year with only a K&N intake and plenum spacer and I was hitting dangerously lean areas (16:1 and higher). You can usually balance out the intake and exhaust mods to bring the AFR closer to ideal without tuning.

The VQ's power doesn't fall off? Really? All of the dynos I've seen have the peak 500-1000 RPMs before redline...

[rich2342]

Maybe you should look again. They climb up to redline then level off..

[Sentientbydesign]

Interesting. That's the first I've seen a VQ do that. Must be the factory detuning hehehe. Maybe the Triple dog will help...

[1125Altima3.5]

Rather than using a dyno, wouldn't it be a more direct (and possibly useful) to measure the CVT's wheel HP using an accelerometer? (you can buy a program for the iphone for $13)

I tend not to trust the dynos that much because there's so much variation in measured WHP between different makes/models of dynos. The accelerometer does introduce the driver factor, but given enough responses (and detail about mods) we should be able to get an idea of the max potential of the car. Physics don't lie!

If the 3rd GEN VQ35DE can handle it. I am sure that the 4th gen VQ's can handle it as well.

Technosquare safely raised the redline from 6600RPM to 7100RPM in their ECU reflash product and nobody has ever had problems from it.

Not a bad idea, but the accelerometer option has it's own flaws to contend with:

> Weight/Mass variances will cause different numbers to come up.

> Flaws in the accelerometer design can magnify greatly. I'm not sure why Apple would spend so much time and money on getting accurate acceleration when the purpose of that feature wasn't to accurately measure your car acceleration.

> No SAE correction factors. This means that ambient air temperature and relative humidity are not going to be taken account for between runs.

> Tire type...

> Oh and hopefully, all those who try this method are smart enough to keep it on the track. Using various streets is not only dangerous, but also inaccurate as the slope of the street will make a difference in acceleration numbers.

You would think so...

I was reading a thread in the g forum here were the engine was blown. He was modded with advanced timing and had had the crank position sensor replaced quite a few times. After that they blamed the mods and it was attributed to the advanced timing.

[1125Altima3.5]

There would definitely be a lot of variance between different cars, but overall I think the cheapo iPhone + Car Temp Sensor + weather.com humidity is preferable. I say that because the instrumentation is standardized, and more importantly cheap/easy to use. That means more people could get numbers on their cars.

I'd guess at least 40-50 people on here have almost identical setups (I/E) so we could probably get a much more reliable data set than the 4-5 dyno runs posted on the forums.

And definitely keep it off the street...

Thats fine, I have no plans of advancing my timing, just raising the rev limiter and tweaking the A/F ratio a little is enough.
