well i have scanned a couple logs with freescan and i found out that my MAF sensor readings are very low....at WOT i seem to be able to only pull around 170-205...a buddy with a 95Z has told me that even the restrictive stock airbox flows more than that at WOT....he said hes aroung 240+ at WOT...my intake is as restrictless as they come....2 filtercharged K&N;s..SLP CAI to descreened MAF to Trick flow elbow to airfoil.....why is my maf flowing such low numbers and what are my options....

 

at 5700 its only flowing 200......idle is fine 6-9

im really getting pissed about this...i dont know what to do though? any help/suggestions

I can email my logs if someone would like to look at them...u can see how much its flowing at what rpm...i wish i knew what good specs were for flow

 

valve float can cause it & so will any leaks before the MAF ie. intake manifold leaks, TB leaks, elbow ripped etc... or bad MAF.

 

everything is air tight..no leaks...

i have some Gumout Air intake and throttle body cleaner...can i use this to spray down the MAF sensor to clean it? Also can i buy a MAF screen at the dealership? Im almost at the point where im just gonna throw out my SLP CAI and get a AS&M CAI and z06 maf...200 at WOT is ridiculous as a stock box flows 240+...wtf

 

well cleaning might help but the screen won't, essentially you get smaller readings with the MAF screen from my experience of trying it on & off several times.

Find out if you can borrow a maf from someone.

Matt.

 

maybe i should just get a Z06 MAF...its 150$ and the entire thing is a direct replacement...the sensor is the same one as i have in there now..

since im flowing 180-200 at WOT isnt that a good thing b/c it would be leaning it out a bit? or is 180-200 at WOT something i should be worried about and is cosing me lots of HP and performance?

i would love it if injuneer (fred) or shoebox could look at my logs

 

its costing you lots of HP, small differences in the MAF readings make big differences on your A/F readings. Your readings would be way too lean IMO.

 

ok i cleaned the sensors with rubbing alcohol...took a couple logs and still no real difference...can someone please look at my csv excell files from freescan and tell me what you think..PLEASE...fred???...shoebox??? i can email you the files asap...i need a diagnosis

 

so your telling me that there is no one on this board who knows about scanning and specs and cant look at my excell file to give me their opinion?
