Actually, the cutoff is really good for oncoming traffic. I aligned them according to legal requirements.

There is a little embossed square in the center of each light portion on the front of the headlight housing. On my car this is 23 inches from the ground. The cutoff for the beam pattern must not be higher than 23 inches at 25 feet.

Little update... I attempted to "tune" today. Basically just fumbled with tuner studio, cursed alot at the serial to usb cord until everything connected with ms3basic, then freaked out some more.

The car was running pretty rich for a while, (11.5-11.8:1 wot at 7100rpm) and I just kept making small percent changes to Fuel VE Table until i got 12.9-13.0:1 wot at 7100rpm Feels stronger now, but who knows. I couldn't figure out how to find the virtual dyno software.

Then, I changed my vvt table from this...



To this...



And holy **** that made a huge difference in low end acceleration. I don't really understand how, but now the car can be on cruise control in 6th at 40mph. Accelerating requires much lower throttle inputs than before. Really staggering. I probably messed something up.

Why did you remove the 0's from the lowest load rows?

No idea, i just copied that table from someone who posted it in the vvt tuning thread.

Was I not supposed to change those 0's?

I was mostly wondering how it would affect things re:engine braking. I.e. if you step off the gas during cruise. That's a pretty low load and not really something you'd see out of vacuum, no?

I have no experience tuning VVT. I just thought that similar logic would apply to this as it does to spark advance.

Oh. Well, it already wasn't smooth, so maybe I wont notice. Otherwise, I can just take it back out? Having too much advance down low doesnt damage anything, does it?

You need a 0 before 1500 because anyway it doesn't work lower than that, and you can go up to 40 deg.
It really is best to tune it on a dyno though.

So, just to clarify, I can try values of up to 40 on that vvt table? I will take out values before 1500.

Also, is there some way to get ms3 basic to hold a specific afr? It doesn't follow the afr table, but I think thats because I adjust the Fuel VE table (which i dont really know what this does, V just told me to alter this when adjusting fuel for different altitudes, so that's what I've been using)

Should I be setting the afr table to the values I want to target, and not using fuel ve table? Can I set an afr hard limits at various rpms?

Is there a graph where I can mess with the altitude fuel correction? I vaguely remember seeing a curve that could be adjusted.

Sometimes the afrs keep climbing and other times (same altitude, and settings, just a different pull) they stay rock solid.

Don't the AFR's depend on where in the VE table you are when you do said pull?

dude you need to start reading up on ms tuning and don't touch your car until you actually know what you're doing. no offense of course, but you're seriously just pecking away and copy/pasting stuff into tables that you don't even have a shread of a clue of how they work or what they do. and that's how people blow stuff up and/or damage their engine

In the theme of what Vlad is saying, read up on "Incorporate AFR Target." If you don't have this on or if you turned this off, changing the AFR table won't change fueling at all.

The problem is that lots of settings interact, so you need to learn a fair amount about the whole picture to make constructive changes.

his car should have it on. I tuned it a year or more ago. it ran flawlessly here in Sacramento. his troubles are from taking it to 7000+ elevation and not making any adjustments

Update!

LOVE THE MANUAL STEERING!!!!

Turns out I had over 8 degrees of caster, so that was why my steering effort was extreme.

Just got an alignment today with regular (i was running extended length) ball joints, and my caster is now 4.5.

I'm actually surprised how light the steering is without ps.

Even parking lot stuff is very manageable now.

YAY!

Glad to hear it. Caster makes all the difference.
