Intune MAF voltage

turbonova · Post by **turbonova** » Tue Jun 16, 2015 3:13 pm

maybe I am missing something obvious but I am having an issue getting MAF voltage to show on the intune screen. What are the steps to make it show? I can get MAF in G/sec

what vehicle?

lots of EECs dont even have a MAF V PID....

03-04 Cobra?

Ryak1z6 tune

I can get Maf counts or G/sec but PID show MAF volts but does not show that way.

So, Mach1?

I would imagine its similar to the 4V cobras:

Well, the reason you can't find it is because Ford never put it in there for you on certain Cobra calibrations. So, if you are using a Predator to datalog and would like to know where you are in the maf curve when tuning you will have to do it another way. The easiest way I have found is to log the parameter called "Maf", sometimes it is found in the acceleration wot or the fuel section, just depends what revision you are running. This parameter will display maf in units of grams per second. From there I convert it to pounds per minute which is the values displayed in CMR. This will aid you in knowing where you need to adjust the maf curve. As well, looking to the left of that will give you the maf volts you are at and help to show if you are hitting the 5 volt limit.

To Convert g/s to lb/min multiply the g/s value by 0.132277

using Intune. Yes shows it as an available pid but I can only see grams/sec or counts but not voltage as tagged. Ok that will get me going fine.

according to that the grams/sec are 750 my lbs per would be 99 at an idle. that isn't right. but what the intune is reporting.

looking at the data on the intune or in DV?
can you post the log?

Thanks

looking at intune. Have not been able to connect to dataviewer. Maybe 2 decimal places need to be there?

try just opening the file in DV to see if the data looks correct.

This still isn't working correctly. Could it be reporting raw AD numbers in the Intune? definitely no grams/sec, lbs/hr, lbs/min the number that it spits out is way too large to convert to any of those. This is something pretty basic needed to tune the MAF curve. Pretty disappointed in the Intune so far. I cannot get the Dataviewer to connect to it, can't get the Maf voltage to display correctly. 3rd time the car has been to my shop and on the dyno, for something pretty basic that should be easy.

what versionof DV?
If not 3.3.0.15, please update it here:
