Stage 2 Sport -- Need Help

marv85 · 10-11-2011, 11:31 PM

Hi everyone,

I've installed Stage 2 Sport this weekend, but I don't feel the extra power!
The logs seem to prove that. Moreover logging showed 2 more worrying issues that I would like to know everyone's take on.

BTW I'm sure I have stage 2 installed (double checked, and AP shows that, and 29f4/5 codes are masked).

Looking at the data, peak boost was 13.25 PSI.

Other issues that worry me:
1) after 6000 rpm, Boost falls short of Requested boost. Does this mean my turbos are going south and can't hold boost? anyway to check?

2) Cylinder 5 timing shows a drop... what is the cause of this usually? could it be the spark plug?

Boost reporting past 5k RPM on the Cobb stage 2 beta maps is inaccurate. Disregard that.

Did you log only cylinders 1 and 5? Or did you log all six? Can you post a log of all six cylinders if available?

A single drop in one cylinder isn't a big deal. When you see multiple cylinders drop timing at the same time that's when you have something to worry about.

Is Boost reporting wrong even on stage1? I should log when on stage 1 to see if I see the same issue

Yes I did log all 6, I haven't posted those because all of the curves perfectly match (overlay) except Cylinder 5.

What's your take on Stage 2 performance? Shouldn't see more boost? I mean it's exactly similar to stage 1 (from peak boost at least)

No, the boost reporting is only wrong on stage 2 beta maps. A firmware release later will resolve the incorrect boost/load reporting.

But good, if you had a drop in only one cylinder, nothing to be worried about.

Good to hear, thanks for your input!

yeah but OP is still only seeing 13psi boost at low to mid rpms on stage 2? Is that normal?

enrita · 10-12-2011, 05:52 AM

seems you have throttle closure between 2800 - 3800 , that might explain the low boost on low rpm .

Yes but if you look at his req.boost its never over 13!!

themyst · 10-12-2011, 09:05 AM

Guys if he had a boost leak his wgdc wouldn't be at 30%. It's a boost reporting issue. When we stage2+ guys report 18 psi, it's below 5k rpm.

If the op wants a second opinion, email Cobb. There is nothing wrong with that log.

mithiral67 · 10-12-2011, 09:39 AM

Full uninstall, refresh of software on AP and reinstall.

marv85 · 10-12-2011, 10:42 AM

I wish I had another log of stage 2 sport to compare with, all logs are for stage 2+

I guess I'm going to email COBB.

and mithiral67's idea is not bad either, I should give it a try

marv85 · 10-12-2011, 10:43 AM

May be COBB can dial in here

+1000

Cobb says that's not needed but experience taught me differently.

Is it the extra power over stage 1 that you are not feeling?

That's correct, and assuming I have problems feeling :P shouldn't I see more boost? I mean I see the same with stage 1 Sport may be even less than stage 1.

Thanks!
