GFX Dave's DarknessMobile in the parking lot @ Naperville Central H.S.

 

I'm assuming that he was attending Ribfest, but then again..........

The question is how did he get to part there???

OK, read that. But I do not have nor have ever had the infamous 'studder.' That I have the 5EAT means I don't relate to the shifting anomalies. In fact, at this point in my tuning, my car works great under all conditions.

 

As far as the ECU abandoning OL/CL with 0 delays....

 

However, now that another evil doorway in ST has been cracked it means I will have to investigate.

My car does as well, I guess we both should get a cookie

I did not have the infamous stutter; I was talking about the transition constantly into OL. I don't know why you would want the car to run in OL at all times other than cruise or decellaration.

Good point.

 

-I ordered the Tactrix (been meaning to do that).

-Ordered the M-300 for ST

 

FWIW I talked to Jarrad at PDX and he said they were changing all of their LM1s for whatever company does the M-300 becasue of timing errors and a few other problems they were having. They M-300 seems to be widely recommended.

Not according to this article:

which just proves that it is impossible to get definitive answers to some of these questions.

The original thread RC posted discusses why I made the switch away from 0.

Boxer - I offered to help

Forgive me, but when I said that the heater needs to be powered I meant that the sensor has to be functioning; you will damage it in a few hours if you leave it in place and not "hooked up"

If you mount your sensor in an improper location you will have problems; that applies to almost every part on the car.

The metric thing did throw me off

If it were my car I would figure out what was happening and fix it.

That's sounds about right

Something is very wrong, that much we know for sure. Have you altered the dynamic advance table? Note that the Dynamic advance is falling through 3rd gear, maybe you should test your thermocouple The most obvious cause is that the charge is being heated too much.

thanks

 

Why not just change it to log in Standard units? Makes life a lot easier

How's that math go?

Those logs are in metric units with bar for relative pressure?

Whatever is going on there is a real problem - negative dynamic advance is NEVER a good ting, your car must feel like it falls on its face. It would be good to see actual timing.

Thermocouple probe.

Why didn't you say so It would be nice to see the date from that thermocouple.

The open source tuning people are funny - Street Tuner works perfectly fine and it logs just fine too

Now on to your problem. I would check your OL delay. I would bet that it is set too high so that after you shift you are going back into closed loop and because the delay is too long, real knock is occurring. Don't set it too short or it will cause other problems. I used 100 across the board and that has worked out fine. I posted about this a while back. Even though no one listens to me you might find this useful

I disagree that the only cause is overheating the air (I know the air is hot, but there must be something else), and here is why:

 

- It is cool (60deg) when I am doing these runs, and I make sure to cool down the IC before I do a logging run.

- It is only at 17.5psi.

- It happens like a light-switch, it goes from dynamic advance in third, to dynamic retard in fourth gear, always during the shift, and it only takes .2 seconds....

 

I guess I should turn down the boost and see if it happens at say, 15psi.

 

thanks for the discussion

The air that comes out of the turbo after being compressed is not quite as cool, that's what the intercooler is there to deal with. Also, only logging during ideal conditions is a great way to end up with a map that doesn't work very well.

Your load is being calculated differently than the rest of us - it does not take a very large turbo to get calculated loads over 3.

Right or left side...

He needs the right side (passenger's side, turbo side).

Whoever gets the lower ET can't post for a week?

I think you have that backwards.

Even? Your highly engineered system vs. his shade tree POS hacked together mess?
