Will getting the pathfinder throttle body wit a jim wolf ecu be enuf to feel a oticeable difference. If I am getting a pathfinder throttle body should I order my jim wolf ecu wit timing very advanced to get the most out if it.

 

You'll feel a difference in throttle response with a larger TB, but overall power gain from a Pathfinder TB on a NA 3.0 is going to be marginal at best, unless you do other things to significantly increase the airflow (i.e. cams, high rev limit, or VQ35 swap).

 

I just trapped 101 basically with the 00VI and only 4th gen TB and that's with 7000 rpm limiter. Plus the recent dyno from Joe showing a mid-range loss and I'm not convinced PF TB is the way to go on a 3.0.

I have one but been debating whether to put it on or not...

 

let us know the outcome when you do.

 

You would be a lot better off spending the $500 on a MEVI, 00VI, or swapping in the DE-K than spending it on a JWT or TS ECU. With the MEVI or 00VI, it'll scream on the top end. The DE-K will give you better power on all parts of the powerband.

I wouldn't worry much about the ECU and TB. There was someone that had a MEVI, stock ECU, and stock TB that got 205whp.

 

Thanks alot foo. Once again u save the day wit ur knowledge. One more thing, how will the 3.5 conv and pathfinder tb reactmwit jwt or ts?

 

Those dyno results are VERY questionable. His numbers are higher than any other maxima, ever, with those mods. I'd take those numbers with a grain of salt. By NO means is that typical.

 

Who owns the dyno?

 

I'm not sure, why?

 

If you do the 3.5 swap, it would be a lot cheaper to convert the egas TB to cable driven. The mallfinder TB is hard to find and if you do find it, expect to pay $100-$200. Go look at my sticky. There's some pictures and directions on how to convert the E-gas to cable driven.

An ECU upgrade will net you much better gains on a 3.5 swap than with a 3.0L. ECU upgrade on a 3.0L without a VI would net you 5whp or less. On the 3.5, you're prolly looking at around 10whp, maybe 15. If you do that, have them advance the hell out of the timing and do a 7200rpm rev limit. Alternatively, you could get a E-manage Ultimate and do the same thing, plus a few more things.

 

I agree that those numbers may be a little high. I can't remember the exact details of it, but my larger point is that a ECU and TB upgrade won't net you much power on the 3.0L. Especially if you don't have a MEVI or 00VI.

 

This is what a MEVI or 00VI in combination with a JWT ECU will get you....



After 5000rpm, the stock intake manifold gets

 

Improper assumption again. The gains from an ECU on a 3.0 have been compared to the gains from an aftermarket y-pipe. Like +12 HP/+12 TQ. That's with stock intake manifold. Where do you get this stuff from? Just wondering...

 

No. An ECU will net you substantial gains, VI or not. I agree with the PF TB though. Pretty useless on an n/a 3.0 IMO.

 

I seriously doubt that you would get 12hp/12tq throughout the powerband with a stock 3.0L. Please show a dyno where this is the case. I could believe 12hp with a 7200rpm limiter with a 00vi.

Another thing you have to take into consideration is the mods are less than the sum of their parts. Using ricer math, you could say

12hp ECU upgrade
20hp Y-pipe
10hp intake
25hp 00VI
10hp catback
10hp UDP
____

77hp + 190hp = 277hp. No need to get a 3.5!!! But that simply isn't the case. Your dyno numbers for the above mods would be around 200whp/200wtq which would equal about 240hp. I think the only mods that are really worth a d*mn are the 00VI and a y-pipe. Those two mods alone should net you 190whp-195whp.

 

Ricer math ... ..
I've seen dynos add 8hp/12tq JWT on a 3.0L.


BTW There's also no dyno with 10-15whp from advanced timing w/ 3.5L either

 

The 3.5 heads allow you to advance the hell out of the timing, a lot more than with the 3.0 heads. I think Tilley may have upgraded the ECU, but I don't think anyone else has. The 3.5swap in a 4th gen will make less power than a 3.5L in a 5.5gen or in a Altima 3.5. This is because the timing in the 5.5gen ECU is more advanced than with the 4th gen ECU.

 

You search. I've seen many dynos over the past 2 years or so i've been on this site.

You're preaching to the choir. Like i've said, many people have compared the gains from and ECU to the gains from a y-pipe. Very noticeable. Perhaps not 12 WHP like i said, but 8 WHP/ 12 WTQ like NmexMAX have certainly been gained, dyno proven many times.
An upgraded ECU is worth it, period.

 

It's worth it much more than a PF TB.

And besides better throttle response, the TB isn't really worth it, and the relation between TB and timing is minimal at best.

of all my mods, I/Y/E/MEVI, my ECU was the most noticeable, and it adds no loud wail such as an intake, or drone such as an exhaust, so instead of placebo, it was ACTUALLY noticed.

 

Here is about 8 whp peak increase just by changing the ecu. The increase in the midrange is more like 20 whp. Obviously no MEVI or 00VI.

However, this is with a dramatic increase in timing.

 

Thank you for that chart. This is one of the MANY that show that an aftermarket ECU is worthwhile, stock IM manifold or not.

 

My jwt ecu gives me 0% HP as proven on a dyno with back to back runs with and without.

 

That is not typical. Perhaps they didn't change the timing or a/f maps. This is what i'd call an anomaly.

 

That's what I was going to suggest.. perhaps they bumped the rev limit and forgot to change the timing and fuel maps...

 

So what I am gettin from this is you can still use the jwt or tecnosquare with the 7200 rev limiter for the 3.5 to 4th gen conv but just ask them to advance the hell out of ur timing. And if you do decide to take this route, add the 00vi and pF tb you should be seeing at least 240-250 whp? Or a little less?

 

Why doesn't anyone do that? Surely there's someone around you 4.5g fellas has a JWT or TS ...

It's hard to throw a guess at whp when no variables are known (i.e added whp w/ timing advance w/ JWT/TS advance tuning etc)

 

There's no dyno evidence yet that says that the 00VI is superior to the stock 2k2 IM. It's all speculation so far.

 

Why do you keep calling it a Mallfinder TB?

 

Housemoms.

If 5.5 gens and 3.5 Altimas can get like 10whp from an ECU, surely us 4.5 gens can get quite a bit more, since we start lower for the timing chart, especially with all the crap I've done to my car.

 

Goodluck wit that. Maybe u can get technosquare or jwt develop a special timing advance for you 4.5 guys. I will be there soon hopefully.
