With the box leaking I was getting KNOOOCK in the midrange (like 5-7*) with a .88 lambda and 20*
Back down to 17*(ho hum
) and more fuel(back to .85).
I think I may just leave it. I want the damn thing to last, and the KDWs are not up to the task of any kind of real throttle mashing.
I should play more, but I will have to with the intake install, which I despise MAF calibrations.
Wish you were up here. I would hand you some monies, and we'd go for a ride, I am that ******* lazy :rofl:

Area helped me out with that ****!

there is a few things i wouldn't change that you did. hence the spiked boost, and peaky dyno numbers. cranking the lower dal cells that you have done cause this. not my personal fav to do.
also the cam timing itself. the tables i run have yet to cause an issue with PTV {piston to valve} why is that? nothing in the part throttle range has changed. if you're conservative with it, you will make more power across the board.
aside from this? good info for the new people to start off with. once they figure out how easy they are to tune, they will see the light.
also. SMOOTHNESS is the key. rapid jumps in the dal's, torque management, fuel, and timing are destined for issues and hair pulling

Before I figured it out I had a tune, with lots of this jumping that is being spoken of.
Spikey boost spiked
Car thought it was a Jehova's witness at times

I tried to see if I could "overboost" the stock turbo... turned off all over boost and underboost ****...
Jacked the DALS up to 360 the whole map from 3000 on up! Wanna talk about a ******' hard ass car to drive! LOLs I couldn't even shift from 1st to 2nd without it starting to spool to full boost!

Liked the write up. Hadn't had a chance to read it til now.
Now you should do a write up for logging everything, and what all the stuff means, for all the people that just learned how to tune from this, lol. We also need a good config written. I wish custom PIDS would transfer through the .cfg files.
Logging, IMO, is the most important part of the tuning process. It will let you know how far you can push the tune, or if your car is gonna blow up if you don't change something.

quick question, figured id ask here instead of making a new thread. im planning on getting tuned by a local guy. he says he can leave my stock tune on and tune only the comp mode. he says thats how he tuned his eclipse as well. i know vince can do on his software so question is, can you do that with hp tuners?

Yea, as far as I know that isn't possible with HPTuners.
I included a LNF.cfg file in my writeup. We still can't log the DI Fuel Pressure but that cfg has more then enough available to put this guide to work! And excellent idea on making a guide for logging and reading a log.

The Map kpa isnt showing up??
I made a cfg based on that one that takes the Baro sensor and subtracts it from the Map sensor, then converts to psi to show Boost in Psi Do you know how to change the chart settings? And write a command line like Im saying?
Youre both welcome

Ok, now for some reason, the way I wrote the line code, it locks up the program every time i open a log. This has been happening to me constantly since the last release of the beta came out. I don't understand, and it only flashes the warning up for a couple seconds, so I can read it all.

When you make the custom Boost in the chart settings one of the 4 or 5 things on the right is units, just set that to PSI. I believe thats all I did. Map-Baro then selected psi for the units
Just saw your edit, I have the Beta and I dont have any issues. Maybe try uninstalling everything and make sure all the folders are deleted, then do a fresh install?

OOOH BYT I love you man!!!! Lol. I have been working the boost PID forever, and just got it to work! Apparently, wha I was trying to do with the ""[SENS.30]-[PID.2340]"" was making it error out, because you can't run a SENS vs a PID... apparently. Now that i have the MAP minus BARO this way [PID.11]-[PID.2340] and it worked!!!

LOL!Glad you got it working! It took me a couple tries too
On a 22psi tune the car took .88 and 17-18* of timing.
Now with 25+ Im running .86-.87 with the same peak timing.

Yes, no homo, lol. Now... I still can't get it into PSI. What code line are you using? I know there is a way to put (PSI) in the code line to convert it, just can't finger it out.

Question for all of you guys running >15* timing peak - why do some people have no problem running 20* in the bottom right of the map, and some people say over 13* is just added stress on the rod bearings?
My solstice is currently at 13* peak timing on 0.87 lambda and only 20psi of boost, and i'm seeing peak VE airflow of 29 lbs/min. Will I really gain much on this engine by adding that much more timing when it's already running so great on conservative boost and timing? The only hardware mods are meth injection and a hahn intercooler...
