Is MS jiving with the reading of your wbo2?

the fuel map showing 255 suggests the MS thinks you are incredibly lean and keeps trying to add fuel to compensate. 255 is the upper limit value.

Yes the two gauges (wb/ ts) agree.

Until TS makes corrections, it is super lean. I listen closely for detonation and am not pushing the engine too hard.

so unless you're running the 255 value the car actually runs lean? I'd say you got a major issue with fuel pump or injectors then, or at least how you have MS controlling them, based on that.

a properly running car will have maybe a 50 point spread between idle and highest fuel ve value. maybe

Correct, If I use "normal" numbers, under 100 it goes super lean. It requires numbers in the 80's just to idle at 14.0 afr. Stock injectors and pump, all works great on stock ecu. So I have assume it is something I have all screwy in the settings.

correct.
or even possibly an exhaust leak pre-wbo2 totally screwing your afr reading

Exhaust is sealed tight..

Is your req_fuel set correctly?

iTrader: (76)

shouldn't it be somewhere in the 12 range?

....even still though, 255 is almost triple what it should normally be

I think mine was 11.4 on stock injectors.

Sounds like that WUE is the issue. IIRC on MS WUE of 100% would be considered 0% by any sane and logical person, and numbers below 100% would be negative numbers. So if your WUE is 20% at normal running temp then its pulling 80% of the fuel, which is why autotune is maxing out the VE table. Copy and past the VE table from the basemap back into the tune and fix the WUE.

If everything else in the tune was setup correctly the injectors would have gone static well before reaching 255 on the VE table.

Req fuel calculator seams pretty straight forward.

Have you run the WUE analyzer?

ryansmoneypit

iTrader: (6)

Not this time. Should the engine always be on warm up enrichment? On the base map settings, it cuts off at about 175 which is less that full operating temp, so I ASSUMED it was for Warm Up Enrichment, not run this all the time enrichment.

im assuming you setup your map to go to 0% at 175°F and not 100%?

ryansmoneypit

iTrader: (6)

Correct.

I'll go home tonight and re do the fuel map and wue map and report back.

You're effectively telling the MS to remove 100% of fuel away from your total fueling and then you're autotuning and the MS is all like: holy **** this moron is making his car go so lean, lets try to help him from blowing it up since he couldnt' be bothered to use any of the great basemaps out there that would get this car 80% of the way to perfection at key-on.

18psi

hahahaha and there it is, Leafy was actually right


and now I'm curious what in the world made you look at the WUE, go "hmmmmmm, lets go ahead and completely alter it drastically" without trying to 1st figure out why it was the way it was in the 1st place.

oh well you live you learn.

protip: when learning to tune, baby steps are the only steps you should take. if you're altering something more than 10% at a time, you should thoroughly question your method

I think this is one of those time when you need to leavve your car alone and go back and reread the basics of tuning a car. Go through the MS guides and really pay close attention. Try not to be in such a hurry and keep from skipping around. When I first started tuning I would get really impatient too and it only caused me to use more time and get frustrated. After you read all of it read it again then start from scratch with the correct firmware and base map.
