Title: 90mm S4 MAF housing scaling Post by: carsey on May 17, 2020, 09:33:38 AM Hi all
Got a 90mm MAF housing here I need to scale into my 018H ECU for a big turbo setup. Does anyone know what ECU code the 90mm housings come off or the software versions? I do remember knowing some S4's had a 85mm housing so dont want to get the wrong one Cheers Title: Re: 90mm S4 MAF housing scaling Post by: Stoti on May 25, 2020, 02:56:29 PM u have to calculate it rough .
