Few more questions now that my car is running on MS
 

Ok so I finally got my ms3x mostly figured out. I am still having a bit of a problem with full throttle above 4000 rpm. Its like the car just falls on its face if I go full throttle anywhere above 4K rpm's. Any ideas? Log/ current tune attached

Log upload keeps failing ... Maybe it's too big?

Edit* - I will take a few short logs of the problem happening on lunch time today and post when I have them. I also just tried adding a little fuel to the entire VE and I will try to run veal and see if that changes anything... Can't drive it yet though because im the only one in the office right now and can't leave yet lol

Ok think I got it all now.

It seems like its almost a rev limiter... It only happens at 100% throttle, at/ over 4000 RPM's

95% throttle acts completely normal. I dont even think the extra 5% throttle even matters for the way the car runs... but I still don't want it to happen.

Are you boosted yet? Can't tell if you are from your sig.

Check your overboost protection, sounds like you're hitting it.

No boost yet... I stole the tune to use as a base from somewhere on the forum Lol... I will check that and see if it has that turned on

I don't think there's an on/off for it, just whether or not it's set too low. I doubt it's your problem, but I would at least make sure it's set to a few psi/over 100kPa.

log the event and the event only.

go recreate it. then press space bar after it happens. that will pinpoint when it happens, then we can look at the logs and see if the MS is actually doing something to cause the issue.


once thing i do notice is how lean you're getting at 100% wot and how your AFR table seems to be setup to lean it out...since EGO is dropping to 94% (effectively reducing your fuel output by 6%).

otherwise, the condition you mention: 100% tps and 4K is no showing up on your logs. it looks like youre lifting around 3700RPM.

Ok I will try again on my way home from work.. Does hitting space bar start the log? I had no idea I could do it that way lol

Make sure your launch control is off..

That took care of it!! Thanks!

I am still going to take some logs to check on what Brain said about being lean. Maybe I need to throw some more fuel at my VE table?

you dont think 15.0:1 at 99kPa at 4000RPM is lean?

I'm not saying that... But what would I do to correct it? change my target afr's? add more fuel to ve and let veal correct it? I'm still trying to figure out how this all works, bear with me :giggle:

ARR Table

So how much should I lower everything... Should I drop the whole table by a few #'s?

1.6 dyno'd at 125hp:

Look at the 100 row. When you go WOT from low rpm, you're going to shoot up to the 100kPa row, and then just sit there until you let off. So currently you're going to sit at 14.5afr until 5800rpm. I'd suggest trying 13.0 across the entire 100kPa row and auto tune for that. Set autotune to "easy" so it really dumps in enough fuel for a few pulls.

Wait is that a different chart than what I have? Mine looks way bigger?

It doesn't matter really.... should be simple to look at the two charts, fill in the blanks.

Ok I just changed the top from 12 to 13 for now and set autotune to easy... I'll see how it does on the way home tonight and make a log once I'm 1/2 way home.

Thanks for all the help guys!

Not the top, you don't use the top since you're NA. Take everything from 80-100 and subtract 1.5.

Ok thanks!

in the least, just copy the 125 kPa row and put it on the 100 Kpa row.
