E30 Zone

Just wondering if the AFM can be removed for better airflow. Thanks Chris

no but if you use Mega squirt you can run car alpha N good results to be had ....
Go to www.fastbimmer.co.uk and ring Ant @ A-Tech

In reality it can be removed for a MAF or MAP or even Alpha-n on the original motronic.

I´m working on a few solutions.

Just wondering if you could run a similar setup to an s14 with a carbon manifold, for a similar sound out of an m20?

Sure you can.

So do you have to run throttle bodies then?

Miller MAF is a very simple and effective option. It is a direct replacement for the AFM, is designed for an E30 and wires into the existing loom. I run one on my E30 and it works a treat.

You are only replacing the air flow sensor, not modifying any of the intake system, whether it be the phlemum, throttle body/bodies, etc... In theory, if you have a AFM, you can replace it with a suitable MAF.

Just be aware, the benefits of replacing the AFM with a MAF, or deleting the AFM with a MAP or stand-alone like Alpha N are not great on a standard car unless your AFM is cactus.

Another big thumbs up for Miller here.

Good product, good support = good experience.

No not at all.

You can run your standard intake system.

fully variable auto TPS + std idle/wot and a remap of the stock motronic AFM voltage tables should be all thats required.

some tweaking of the accel enrich possibly, or MAF/MAP

all are possible but quite time consuming.

so would putting the miller maf conversion on my alpina 2.7 be a good mod???

honestly a very cheap piggyback and a TPS/MAF/MAP can do the same for less

so is this miller maf just plug in and play then?

Pretty much ~ except for about 4 wires and a touch of solder.

nice one buddy, il give that a try!

you can convert to use either a certain part numbered volvo MAF or hyundai MAF with motronic. there was a guy that set both up on his 325i in the states and made suitable maps tuned with a wideband. the volvo MAF requires 2 points on a 173 ecu to be bridged with a peice of wire but can support up to something like 300bhp whereas the hyundai unit will only support up to around 230bhp if memmory serves.

i have both maps saved on my laptop along with the map editing software but i havent found either MAF sensor yet and ive sort of put the MAF conversion onto the back burner as of late because i firstly need one of the MAF's and secondly need a chip burner, chips and wideband to monitor everything.

Interesting thread, be keeping my eye on this for my 2.8 conversion

Dose this maf convertion add more bhp? If so roughly how much ?
