you are a little rich in your WOT on your mafcomp.
also most people suggest to add or subtract timing and fuel from the direct access tables, not the slider tables. it still works but it's better practice to use the direct access tables.
how much boost are you currently running?
 
Duly noted. Im aiming for 11.5 afr in wot is that okay? 20 psi.[DOUBLEPOST=1417369905][/DOUBLEPOST]Hey quick quesption. Before I mess with DE tables should I zero or adjustments on the sliders first or play of them as well?

sliders ADD or subtract on top of your DA tables.
zero out those sliders and do it all from the DA tables.
11.5a/f 20+psi WOT is alright 93+ pump gas. watch those EGT's though or you could meltdown if your careless. don\t go above 1650f-1700f and you should be fine.
how much boost are you running?
 
There are so many wrongs here, LOL....

Your MAF calibration is drastically off. You are adding a LOT of airflow/fuel that you shouldn't be with your MAFComp sliders. Then you are subtracting a lot of fuel with your fuel sliders. You are also playing with fuel and timing sliders which is kinda half-ass.

First we calibrate the MAF - You say you are running 20psi but your ECU thinks you are running nearly 30psi. You need to subtract 21% on your MAFComp sliders @1900 Hz. Basically you want to be at 7.8 @ 1900 Hz all the way to 3600 Hz. Anything under 1900 Hz you want to blend to match your mid range sliders (~500 Hz). Once you get your BoostEst to match actual boost @ 5500 RPMs do not touch the sliders anymore(besides idle).

Next we calibrate the injectors - Zero your fuel sliders to start. After that make your pull(with newly calibrated MAF) and check to see how close your actual AFR and AFRatioEst are. If you are lean then add fuel back in with your Global Fuel setting. If you are rich then subtract fuel.

Finally we fix the idle - At idle check your AirFlowPerRev and make sure its ~.25. If not then you need to either add or subtract airflow at the given Hz signal. Once you are calibrated you then watch your STFT and CombinedFT. If rich then subtract injector deadtime and if lean you add deadtime.

Do some or all of these things and report back with a datalog or two.
 
Okay so don't go DA route?

Thanks for the helpful tip. See it was my first "half ass" tune.. I guess. But I had slmeone look at it and was told it was good. I'll go your route instead.

Thank you very much!:thumb: will have one up tomorrow after work.
Bryan[DOUBLEPOST=1417529709][/DOUBLEPOST]Hey did you find that i needed to subtract 21% by using this equation?

(Actual boost + 14.7) / (boost est + 14.7) -1?

Just trying to get this tuning finured out finally. And reassure myself

Yes, that is the formula to calibrate your MAF.

And yes you do want to use the DA tables and not the sliders. Sometimes sliders can be useful for some quick changes on the fly(where you do not want to shut the car off, etc) but anything permanent should be set through the DA tables.
