Does anyone know the MAF values from an SVT? Ive got my stock ecu dumped to a bin file and i want to switch to the SVT maf housing, have found the tables for it but not sure what the values are from the SVT.

Im trying to avoid running to sensors and housings and logging both and transfering the values if i can since im sure my values wont be 100% dead on and i would perfer to use fords preset values.

Also i dont have access to an SVT ecu to pull them my self.

I know this wont be exact but its a start :D

Just use the ZX3 you have and make your own from there , start the car and change them to whats needed to get the trims right , dont know why anyone uses the preset stuff anyway

I agree tom thats not a bad idea. I just wanted to know what ford used as a starting point so im not trying to re engineer the wheel.

Well i did the 70mm svt housing today...

I got it running but i used the wrong value for the conversion.

I thought it was 1.562 so i used that and it ran nice and smooth but found im runnung a little rich. Re did my math and it should have been 1.3611. Not a big deal ill wait till the next weekend to reflash it.

On a side note i disabled the egr, 2nd o2 and setup a 4k 2 step and those all worked mint!


What i did to get those values was get the area of a 60mm and 70mm and then worked out the difference. Origionally i tried for factor in the size of the sensor as well but realized after that wasnt needed and thats where i made my mistake.

Now you need to watch the STFT1 and see if they need some trimming

I think i might break out the wideband tomorrow and see just what i got done to it. I can feel there is less timing so i know i scaled it wrong. Ill put in the 1.3611 value tomorrow and log it with the wideband and see where im at.

Side note it runs alot better with egr turned off and my 2step might be a little high.

I wont mention what hardware of software im using for obvious reasons but im not sure i can check the STFT with it. I have to do everything by HEX and that kinda sucks.

Ok well i tuned ot again today, changed to 1.3611 multipler instead of 1.562.

Its better but still not right. I think i got my maf sacling incorrect. Its runs good and smooth but i think ive changed the scaling and its throwing my load off.

Does anyone have the maf values from 0-5v or a stock svt bin file so i can just pull them for now?
