I haven't been following the 15hp and ECU Update threads, but say nothing similar has been brought up. Is this possible?

I had my MAF replaced and ECU updated per the TSB - and before i even put in the BG44k i already noticed that the car was running much better. Better and stronger pulls throughout the rpm range, it just feels like i've gained quite a bit of power somewhere.

Could the ECU update mentioned in the TSB be the key to the missing 15hp? (Or a part thereof).

Did anyone who had the ECU update done go for a dyno and had a non-updated ECU dyno to compare it with?

Just curious.

 

130 views and no one has anything to say?

 

i would respond but i have no clue

 

I had that tsb done and i did not feel any power increace, it just felt like my engine got smoother.... BG44k is a different story, that stuff is nice

 

Is what possible? WTH are you trying to say?

 

It is possible. But I doubt that is the real culprit.

 

The whole 15HP thing sounds like something Nissan leaked to try to pacify people.

 

What?

The 15 HP conspiricy is that our engine is rated at 255hp/246 tq by Nissan, and sold/marketed/advertised/pushed speciffically as a 255 hp car. We really have the same engine as the Altima and the Pathfinder (245hp/265tq). In all reality, it should be the missing 10 HP conspiricy, but at the origins of the conspiricy, most thought that our engine produced only 240 hp...

The TSB for the Hesitation/Lack of Power does not restore the missing conspiricy theory 10-15 HP, but it might actually give you some power that you were losing due to crappy MAF sensors and a bad ECU program from the factory...

The TS ECU, on the other hand, will probably be able to give you back the original lost HP and then some (more like 15-20 to the wheels).

 

I definately felt more hp in the butt dyno when I had my MAF/ECU upgrade done. I wonder if anymore tweeking is available.....hmmmmm

 

Yes...you can advance your car's timing...

 

IMO, that 15hp issue is part of a larger VQ35DE conspiracy. Like the fact that the 6sp G35S is almost as quick/fast as the G35C 6sp which is alleged to have 20hp more.

 

I think Nissan does it for marketing. A guy on G35driver.com recently dynoed his G35S 6mt and he came out with 238 RWHP. Considering drivetrain loss that puts him right around the 280 mark. It's all fine an dandy to bench race with all the numbers put out by Nissan but real dyno numbers is where is it at. Has anybody dynoed their car to get some wheel horsepower numbers?

I understand the whole 15 missing HP theory and it's origin. What I was saying was that the rumor that the TSB would give you your 15 missing HP is bunk, and would likely be a rumor started by some Nissan dealership somewhere trying to mislead and pacify people to keep them "happy".

 

So there really has been a rumor that the TSB (ECU Update) gives you back the 15hp?

I just figured i *may* have gotten some sort of bump in HP since the Max has been performing quite well since i had the MAF replaced and the ECU updated. And i'm not the one to usually stake a claim as strong as that.

 

I don't know if you'd call it a rumor or not, but I have seem intermittent chatter on here about it every now and then.

 

Have you done this? I asked dealership and they said some bull$hit that it couldn't be done.

 

Yes it can be done. Many have had it done, all by Nissan Techs. If you do a search you'll find a ton of info.

 

I'm trying another dealership tomorrow so I'll try again.

It used to be that dealerships would do it, but i guess it became quite rampant since most dealerships here in Houston would tell you they won't do it anymore.

 

I don't know about advancing the timing on your 2000, but I know how to advance the timing on the '02-'03 Maximas...

 

look i know wheel weights can affect a dyno, am i right?

do you guys think Nissan used the GXE 16" wheels from the 2k2/2k3 to get this number?

 

pls tell me how? before you did this were u getting a lot of pinging noise from the engine, sounds like you put super cheap gas in your tank.

 

the only way to adavance timing on 00 and 01 (and i'm assuming 02 and 03) is to have them hook up the machine at the dealer and crank it up using their diagnostic thing. sorry, can't remember the name of the machine right now. you can go +3 without any other changes (18 degrees btdc), after that you need to manually adjust some stuff to get it to stay (idle air volume learning thingy).

 

I'm very interested in how to advance / retard the timing. Please tell us how. Thanks.
