Default How do YOU tune?

and i dont want to hear "take it to the tuner"

i have had a friend drive the car before while i was in the pass seat with the laptop and that seems to work decent. but its hard to find someone you trust enough to drive it at the same time that you have time to tune it.

so my question is how is everyone else tunning thier cars? i just upgraded to high res, and just threw in the MSPNP fuel map with my req fuel, and it needs tuned BAD, rich everywhere. just want to hear how others are doing it to get another perspective.

you drive & log for 10-15 mins varying the load and rpm combinations to cover the whole fuel map.
run log through VE analyzer in MLV.
accept new msq.

repeat.

i have never used the VE analyzer. looking into it now, thats some cool stuff. much easier that just looking through the logs and trying to tweek the map like i was doing.

When you talk about load, you make reference to what?

Engine load, 30 kpa is a low load situation 100 kpa is WOT when NA. He means put the engine under varying loads relative to RPM to hit as many cells as possible in the VE table. Then let MLV work it's magic.

I couldn't get my MLV to open. I guess I'm going to have to reinstall it.
I started from an idle touching the pedal and advancing to my brother driving me down the street chasing the green dot on Real time. It took 2 hrs to get a tune so I could drive it to work safely. As soon as you would let out of acceleration it would lean out. I'm lucky to have a Q & W still on the keyboard. LOL

Autotune is much simpler than MLV. You don't have to reload the MSQ all the time just drive the car and it tunes on the fly. Doesn't get any easier.

however it doesnt work nearly as well.


it's easy for me to drive to work and record a log. run it through MLV and flash it at lunch. It's usually good to go after a few sessions, when you get to the point where EGO is almost always 100% I turn MLV to hard, then very hard. I can also tell it to ignore anything under 35 kPa and 1800RPM.

Driving with autotune is a good starting off point to get you in a spot to start using MLV.

That's true. I have used MLV to adjust specific parts of a map, and I'll be using it to adjust throttle transitions and off idle conditions. For general tuning (cruise, part and full throttle) though, I like autotune.

MLV kicks autotunes *** at all tuning end of story. Autotune is incredibly incompetent and slow. MLV gets everything ***** on for me, like Scott said, close enough that EGO hardly has to do anything.

Autotune is far too slow for anything but cruise. Using it for any kind of acceleration is pretty much pointless.

Ditto. I do the same thing. Log the drive to work, run it through MLV, increase from normal, to hard, to very hard for subesquent tuning logs. Alt-L baby.

good tip. i forgot to mention that. I like to set my idle manually and don't let VEA modify after.

as someone said above, ALT-L Enter to start a log, then just ALT-L Esc to end it.

How do you do that?

I do the same thing all these guys said and it works great. Its easy to figure out and work with.

^ press on advanced settings in the VE analyzer and you can set bounds.

ve analyzer is your daddy. I prefer using that interface to tune tables.
