I tried the link from Throckmorton, but it didn't give me a listing immediately. But then I put in "Altima Sedan" and "engine control module" in the search boxes, and I found 11 units listed. When I changed the "sedan" to "coupe" (CL32) I found 14 units listed. Didn't compare, but there are clearly some differences. Manual trans, CVT, fed, and Cal seem to be the factors that require changes.

I think I have it correct now. Then again, I might not!

Nissan lists 3 ECM’s for the 2007-2009 Sedan 3.5
Nissan lists 7 ECM’s for the 2008-2009 Coupe 3.5

The part numbers for the 3.5 Sedan:
L32009 2007+ SE3.5
L32010 2007+ MT
L32011 2007+ SL3.5

The part numbers for the 3.5 Coupe:
CL32002 2007-08 CVT
CL32003 2007-08 MT
CL32008 2008-09 CVT (AIRRF) 50 state emission
CL32009 2008 MT
CL32010 2008-09 CVT
CL32011 2008-09 MT
CL32015 2008-09 California Emissions

The ‘shared’ units are 009, 010, and 011. So, 7 different ECM’s cover the 3.5 Coupe and Sedan.

No wonder aftermarket tuner manufactures have problems getting every application to work properly.

Thats just what the tach says, the ECU reports a different number.

So you think the tack is off by 300RPM's????

but looks like the ecm for the CVT coupe is the same as the MT Sedans

Well so far I am not having any success for the Bullydog tuner.
I got the update from the engineer's today for my car and I was able to download the tune to my ECU.

I set the tune to Premium
Rev limiter to 7100 (you can't set it any higher btw just like a technosquare reflash. So I'm guessing Nissan knows this motor can take 7100 RPM)
After thats all done I tested her.

Doesn't feel any faster than before, rev limiter still will not go higher than 6700RPM.

So I'm kinda disappointed so far. GL to you guys tho guess I'll call tech support.

sorry dex, hope it will work for you and others.

That is disappointing. Are any of the supplied model and engine numbers correct and vice versa the tune they provided if there are multiple models?

Could they have given you a tune for a different model # that wouldn't work for you're specific application?

What is their response to zero result?

So I guess were just hopeing you got a wrong tune or somthing? I really hope this thing isnt a waste of money. Mine should be here tomorrow or monday. I will be doing a Dyno ASAP to see if this really works.

 

[Dexion]

Ok I have two videos one I just took.
Obviously the rev limiter modification doesn't work I'm not sure if the premium tune and the +2 timing advance added power. It might have... but a dyno will prove it once and for all.

I dunno, what do you guys think. Same? I wish I had some headers, lol.

Incredible

17 pages thread and still nobody can just bluntly state that the bullydog is just a scam

I guess that's because it is NOT a scam. Some people have their heads poked deep where the sun never shines, and they have no knowledge of aftermarket ECUs and reprogrammed ECUs, but others who have looked around have seen that there are some gains to be had from things like the BullyDog, and Osiris, and the Technosquare reflash. For some cars/engines, the reprogramming is relatively simple, and the popularity of the car means that there are good ECU mods available quickly. (the 350Z, the Camaro, etc) There hasn't been that much interest in performance enhancements for the Altima, so vendors are slow to develop things.

 

[eddie_obie]

Well by head is realy stuck-up my 15 years experience with MegaSquirt, Microtech, GIAC, WolfEMS...

As for Technosquare i really respect them so i can take them out of the conversation, Osiris i have no experience...

Bulydog, Superchips, JET.... waste of money

Dont call it a waste of money untill someone dynos it and gets no gain. Mine is suppose to come today, give me sometime and I will have some dyno results, you guys know me Ill have them up fast, I do hope someone does it before me so I know what to expect.

No problem!! hope you prove me wrong...and i will gladly be wned:

PS. $468 for only having the advantage of advancing the timing is rather expensive

Here is the problem that I have with dyno testing. Testing is done at WOT, correct? Let’s play nice and look into our crystal ball and give Bully Dog the benefit of the doubt, and say that BD finally got every Altima application working as advertised. Some will say that this is wishful thinking, but follow my logic on this one.

What if the BD tuner gave real world performance gains in the 2500-4500 rpm range, under less than full throttle? The dynamometer would not show this gain over the stock set up, would it?

Or, lets say that with the BD set for maximum performance, the dyno showed that at 6900 rpm, the Altima 3.5 produced 5 more horsepower , give or take a couple of horses.

What I am saying is that maybe the butt dyno would be more accurate in this case. You would feel more of a gain in the midrange in everyday driving, unless everyday you drive balls to the wall and flat out. You just could not prove it by dyno testing.

All of this is just my proselytizing, and is pure speculation, which is quite frankly what I do best.

But it could happen, couldn’t it?

 

[white6spd]

K. Well I will do another test when I get it. My buddies 04 TL 6-spd is faster then me right now. He has CAI STS cat back j pipe test pipe pre cat deletes light weight pulley throttle body and intake manifold spacer. But I use 2 beat him with my mods b4 he did the pre cat delete mod. So if I beat him after the bd then I know there was a gain. I will let ya know how it goes

you got a great point, but stillwill it be fair to pay $500 for 5HP..maybe 5WHP

 

[missouriguy1973]

Nothing is going to beat a good datalogged custom tune...and right now there's nothing out there like that for the Altima, and I really don't foresee anything like that either...It's just not a platform that is lucrative for someone to sit down and create a custom performance tuning system to work with it...There's the base with the Z because it's actually a sports car and there's a huge performance group behind that car to push for products like that...The Altima being a 4 door family car, not so much...

Sure there'll be these types of gadgets that may boost fuel and timing globally through the whole RPM band, but they won't make the car perform at peak potential like a custom tune would...

 

[jkgultimate]

Just get a standalone ECU and your set. Get everything tuned on a dyno lol.

Stand alone ECU? The Nissan Factory Service manual has over 1500 pages in the Engine Control System chapter alone.

I could be wrong, but I don't think it is quite that simple. Looks more like rocket surgery to me.

This reminds me of the first used car I bought from a neighbor when I was about 19 years old. With the old neighbor standing beside me, I was looking at the inline 6 cylinder, and wondering what was making a strange noise from deep within the engine.

His reply to me was simple, and to the point: "Lotta sh*t happening in there son."

I guess that same analogy applies to the ECM. Lotta sh*t happening.
