3 bar tune

He was looking for directions to pull the strategy code using the tuner so he can get tuned correctly.

Was he successful? I went to LMS for this, but would troubleshoot it this morning if help is still needed.

LMS already had my strategy code so I didn't need to pull it when I got the MyCal so I am no help with that.

Regarding the dying duck sound:  It makes the noise whether you have the BOVs vented to atmosphere or left hooked up to the recirc tube.  I tried it both ways and the noise was the same either way.  Anthony said it was due to higher boost but I am not so sure since we get it more after a low boost situation than high boost.  It does, however, seem to be related to a release of boost - however slight.  Maybe it is a result of boost at a lower RPM than the earlier tunes???

OK so this is my idea on the duck call sound.  Bear in mind I'm not using lms and have not heard this in person..

It actually makes more sense that it makes the noise at lower boost.  Your seeing more boost at lower rpm and the bov are only opening part way like they would with less boost.  You have a higher volume and pressure of air being vented through a partial opening.  So you get a new sound.  Kinda like a real animal call or music instrument.

 

[Brucelinc]

Panther, I think you are right on with that explanation!

Still waiting on LMS response at last word.  I've "shouted" him of your offer to help, may contact you via PM.  Thanks

This makes a lot of sense to me.

Think I may have figured it out for em. Haven't got another pm since I sent directions.

The learning curve seems to change as we learn some things with these ECO's.

Before 3 bar I would get a max of .5 degree of knock (timing pulled) ...now from a stop and brake boosting I get a steady 0, but when going wot from a roll it pulls 2 degrees...hmmm?

I have seen up to 2 degrees pulled but it was in a lugging condition - like accelerating from 1000 RPM in 6th gear manual mode.  I was actually trying to lug it to see how much, if any, timing it would pull.  I haven't seen the timing pull at WOT but I will try again from a slow roll and report back.

Appreciate the feedback. Didn't see what gear I was in when I pulled 2*. Really nice seeing a flat 0 from a stop though!

I got a 7 positive reading today so I'm paying close attention now. I tried to duplicate the reading and it seems that I need a slight uphill to load the car, need to be in 6th and I need to give as little throttle as possible. A little too much throttle and the knock retard starts going less positive. Even more throttle and the reading goes negative. WOT is no problem. I've got to bring the car to the dealership next week for the tranny eval so maybe I'll flash back to stock and see what kind of knock retard I pull with that. Might be interesting to try the 4+ again just to measure the knock retard reading with that tune as well.

 

[SHOnUup]

Haven't had a chance to test again, but yesterday I was trying soft pedal on e-way at 70 in 6th gear and would instantly get negative #'s. No hills, and still right on par with the 4++ tune without 3 bar. Think I'm gonna put just a few gauges on a screen in torque to help with lag time and go for a nice ride tomorrow.

 

[SHOnUup]

That 7 is in the scary range though.

If you flash back to stock you will see the same changes.  Moral... Don't lug.... Give enough throttle to get a downshift...  Safer.... And quicker.  The 3.5TT apparently was meant to accelerate fairly hard by design.

Just so you have an accurate visualization, my 7 reading was attained at highway speed on cruise. We are talking very slight uphill and minimum throttle. If you drive interstates and use cruise or drive as smoothly as cruise you could not avoid my experience.

I read here before that people were getting "knock" by light pedaling it on e-way at cruising speeds. So I've tried this many times and cannot get knock. About to coffee up and either go test driving or golfing.

Hill is the variable here I bet. Land yacht up hill protecting itself.

That gauge setup is sweet looking BTW Larry

 

[Brucelinc]

I am an idiot!  Somehow, my simple brain got the readings backwards...I was thinking negative meant knock detected and timing retarded.  I need to do some more testing and look for positive numbers.
