My 350z DE (auto) is Fbo and has Jwt 272 cams.
After tuning (rs enthalpy) my car made 276whp and only 225wtq on a dynojet. I made more torque before the cams! The car is extremely sluggish between 1000-5,000rpm and the general lack of torque is very noticeable. Feels decent and pulls pretty good after 5,000.
Before cams, car ran a 13.78@100, after cams, now the best the car has ran is a 14.2@102

Anyway, my question is, I’m trying to diagnose what could be causing the disappointing power/torque, and one thing that was brought to my attention was cam timing… personally I don’t have knowledge on this subject, but if anyone does and could help, it would be appreciated. I’ll link a pdf of my most recent data log and to show my cam info/timing #’s and %’s.

If you know about what the cam timing and cam related data should look like, could you tell me if mine is where it should be or if it’s not tuned in properly? And if this is/could be causing my lack of torque.

Linked PDF is my data log 2nd gear wot 2500-redline, cam info should be on the far right of the PDF.

Also, I can post my dyno sheet If that helps too…

 

Why did you start another thread?

 

Thought I should post my question pertaining to the tuning side of it in the tuning thread section. And I didn’t want to annoy y’all with continuous follow up questions once we moved from intake manifold questions to tuning questions to cam timing questions lol.
And to get more opinions and info on the cam timing from the data log.
Should I have just kept on in that thread and asked about the data log more in that thread?

 

estimated torque delivery it looks up the bfs and engine rpm and figures out the torque in NM as an estimation for shift pressure, if its auto trans its a necessity to scale it out, trans won't shift properly, and you will have all kinds of problems with torque,
going by you're bfs I'm gathering you tuned by maf not k fuel, what did you set your idle targets at? on my 272 cams I set mine to idle at 900 rpm, what I would do is from bfs 9 and up set the timing to 0 and first dial in the fuel and do some pulls and add in the timing

 

I’m not sure on the tuning side of things, I’m not doing the tuning myself, I’m actually between tuners right now, switching to a new tuner. But what I was trying to get an opinion on was, from my data log I linked how does my cam timing and other parameters look to you? And could that be what’s causing my general lack of torque? Could it be the tune based on what you see in the log? Or if not, maybe something else.

 

personally I can't tell just looking at the log, without cross referencing the maps, and viewing more logs, like idle and cruising, and wot,
when I log I include
afr corr b1 b2
maf mg/s
maf volts
afr target

only thing that you can do is find a good tuner,
