Just did first logs, oh god what am I looking at?!
 

Well finally got a laptop to do logs/tune my MS with. Bought tunerstudio pro, worked quickly, went out and did logs.



Now what?



I'm pretty sure I'm running too rich. Car was tuned by UMS Tuning in Phx when previous owner had the car.


What file do I post?


Thanks guys :idea:

Log is attached now.

How do I adjust boost?

I assume you have your AFR targets set. If so skip the logging and use VE Analyze Live to take care of those AFR's then smooth them over by hand. This method worked much better for me than logging, analyzing, logging, and repeating.

No clue what any of that means. I am an absolute noob to tuning. I don't want to mess anything up changing stuff. (yet)


So I'm not sure what you mean by AFR targets set? I just want to have the car run good. It runs well now but last owner said it was VERY conservative tune, so Id like to get some more power out of it.

I don't have my tuning laptop on hand at the moment but if I remember correctly your AFR Target Table should be in the "More Settings" tab.

You'll want to set this table to give the computer something to shoot for. What wideband are you using? If it's the LC-1 it should be in Air/Fuel but the AEM may be in volts (in which case you'll want to search the boards for the thread that teaches you how to hack the file).

VE Analyze Live is a great feature in TS that will correct your VE tables as you drive. It will get them close but it's not perfect. However it honestly sounds like you need to do some more reading. If you're unfamiliar with AFR targets you're not quite ready to tune your own car.

Doesn't look too bad at first glance. Your AFRs are mid to low 12s in boost. Could be a little richer for safety's sake but if there's no knock you should be ok because it's not boosting extremely high. Your idle AFRs are somewhat lean. Does it lope or have a subtle miss at idle? If so you may have to richen it up some.

Also add a spark angle trace to your log. It seems like it has a lot of advance in boost, you may want to trim that back some to be safe. 26-27% is kind of risky in boost unless your running race gas. Of course every car is different so wait for some other opinions other than mine. I'm still learning myself.

Plus I'm hungry, tired and horny and it's probably throwing me off a little.:giggle:

The table in the lower right is my afr targets in MLV. You set these values in MT or TS under "More Settings" in either volts or afr depending on how you have your shit configured. I've played with my settings since this screen shot and also switched to TS (VE analyze live) but just figured I'd throw it up

**EDIT - D.Dutton took the words right out of my mouth, lol

My AFR gauge goes down to low tens under boost/WOT... I was under the impression it was running too rich, not lean. I am using the LC1 btw

Cspence is right about that being the AFR targets but DO NOT change them in Megalogviewer. I did this once by accident and it corrupted my msq leading to a reflash of the unit.

Make sure you change them in either MT or TS

Your log says otherwise, do your gauge and MS AFRs match? If not you may have to change some settings somewhere. I wouldn't get too excited about boosting until your settings are correct. Small steps, my friend, small steps.

Seemed like it, but not sure on that.

How do i save my MSQ to my computer, etc? So I can back my tune up...

Connect to your MS and file save as...

So how do I adjust my boost?

Does it make sense my boost adjusts accorinf to the heat?



Max boost I ever see is 10 psi, id like to put it up to 11-12

Make sure everything else is right first, then worry about your boost. It doesn't matter how much boost you make if your motor is melted into a cast iron ingot.

Make a list of things you're curious about then search the threads that relate to them. Make sure you understand what your seeing and what your tuning before getting too crazy.

SMALL STEPS!

According to the last owner this tune is "SUPER CONSERVATIVE"


It also smells rich when running, and I get LOTS of back firing...


So I'm not starting from scratch, I just want to figure out how good the tune is, etc

is it bad I let TunerStudio auto detect the firmware when I started the new project?

Conservative usually means a rich ve table and low spark advance under boost. Both of which are done to prevent knock.

And no, I recommend letting TS Auto Detect.

This stuff is so much more complicated than any of the stuff I work on for the Air Force...


and I work on some overcomplicated stuff in the AF.... lol
