MAF installation on e24

[KC Ron Carter]

Here is a MAF from Split Second

The controller is in the glove box, and is indexed to allow me to play with settings and get back to smooth running.

Here is the Ford 65mm MAF and it is made in JAPAN.

If this engine was shiny enough to reflect,
you would see me smiling while taking the pictures.
Cause I really like the output of the MAF.

Six hours, DIY, including the indicator and can switch back to AFM in 2 minutes, Two screw clamps on MAF, two quick electrical connectors and the OE connector is tie rapped back out of the way.

OE is
3430cc M30
Motronic
DME II
92x86, 8.0:1
185bhp/5400rpm
214lb.ft/4000rpm


I own a dyno so here is the output at the wheels.

HP loss in transmission and differential 25%
So 222 HP at shaft is the result.


I am using the J C. chip also, a 3.71 ratio, with 265 Getrag.

The sweet spot of the m30 is now at 2200rpm where it was at 2800rpm.

That is the point where the rumble of the exhaust resonates in frequency with the intake. On the unmodified it is only seen on the cold mornings when the fuel system adds a little more fuel and the cold air is giving it's all.

I really like it.

My Cartech RRFR installed and test in advance of the M102 12 psi turbo.

I hope to sneak up on a few Stangs and Meros on the Dyno.

that's FREGGIN SWEET!
congrats on the install...i'm looking to do a MAF conversion on my car
but a kit runs about 600 bucks...what did u end up paying?

and how long to tune the air/fuel? i mean did u need the dyno to tune
it or can i just do it on an open road?

followed the instructions

Following the instructions,
"Six hours, DIY, including the indicator and can switch back to AFM in 2 minutes,"

I used the Split Second settings and they were right on.

I have made changes and played but he suggested settings were right on.

The cost for the MAF kit was .9 k in dollars.

I have done no tunning yet since the final product is a ways off.

I should be in the 4 to 5 hundred HP range when completed.

Here is my Metric Mechanic Head prepared for the M102 BMW Turbo from a 1986 745i.
