Title: me3.8.3 1.8t tuning/logging Post by: sam on September 28, 2016, 03:14:27 AM hi
I have an audi 90 fitted with a 1.8t (aeb) running me3.8.3 ecu from a golf gti (agu). it was running with a t28 and bigger maf/injectors @1bar boost (mbc) etc and ran great with original file 275bhp/310ftlb according to rolling road. anyway I have moved onto a holset hx35 turbo, the engine will be getting built to withstand it and more revs. my question is does anybody tune this ecu for big turbos such as holsets/gt30 or do people change it for later me7.5? i'm happy to get the equipment together to log everything but don't know where to start on mapping side of things. thanks in advance sam Title: Re: me3.8.3 1.8t tuning/logging Post by: Jim_Coupe on October 02, 2016, 05:49:22 AM I think this ECU work very good for tuning.. I have tuned this with a GT35.. 1300cc E85.. 4" MAF.. But Me7.5 is better i think.. you have more options.. but.. m3.8.3 works for what i need the car to do..

A small tip since you are going to do it yourself be very very carefull with the maf as your fueling will mostly depend on that. Either replace and reconfigure(rescale) or go for an me7.5 swap.

I intend on letting someone who knows what they are doing to do the adjustments If im honest, and I was just looking to log to keep an eye on things. ill do some more digging.
