As for the hardware, would you need something like this?

I have one of Scottie Sharpe's pieces, but I'm not going to use it. See here:

Sorry about the huge gap in updates. A couple of engineers on my team (at my day-job) quit in the last couple of months, so things have been super busy while we try to replace them.

As for the MAF kit, I have been making slow but steady progress. All the software is complete, although it still needs a lot of testing. I also built a hardware prototype to test the software with in the actual environment. I haven't forgotten about this by any means, but my day-job still puts food on the table so I can't go neglecting that either!

Still interested, and hopefully I can convince my (very soon to be) wife that putting a MAF on Betty will be worth the moolah, so I can be a lab rat on this when it's ready for testing.

The MAF should be reasonably easy to justify. Try telling her you want a fully built Metric Mechanic Rally M42 w/ options for a cool $11k!

Would having this piece of CNC'd awesomeness help?

I don't need it and it should really go to someone that can use it. I'll sell it for $150 or trade for an M42 COP kit.

At the moment I might not be able to make use of it. I am looking at using inexpensive off-the-shelf Bosch MAF sensor units & finding the simplest way possible to mate them to the airbox (or just put an open element filter on them).

Well, I have made a lot more progress on this. Software testing is almost done, and I have ironed out a LOT of bugs. This thing is starting to be really solid. I have been delayed by nuisances like having to tear my M42 down thanks to a dead timing chain idler sprocket, troubleshooting a bad ground on my wide-band O2 sensor setup and trying to convince my fiancee that she is at least as important as my car projects.

Anyway, I expect to be designing & ordering some debug PCBs in the next couple weeks so I can really iron the last details out. From there, it is just working out the converter's packaging & cabling. I know this has been a long time coming, but it should be well-worth the wait.

Any updates?

bmwman91 · « **Reply #68 on:** July 01, 2011, 03:39:23 PM »

Yup, I am working out the final elements of the PCB design and working out a deal with a contract manufacturer (in Canada) for assembly. I still need to source some cables with strain reliefs, but the bulk of the development work is done.

Now I’m doing MAF conversion on my M42 (E36)
I bought M52B28 MAF sensor and VAF-MAF converter from here

Hi , I am interested in the MAF conversion and would like to know if the completed units will be programmed with the stock M42 calibration . At the moment I am running a stock engine and needs to replace my AFM but not necessarily interested in tuning a MAF sensor. Also what is the projected cost per unit ?

Thanks
Fabian

I will send the units pre-programmed for whatever car they are to be used on.

Currently, I am looking at $200-$225 for the converter module & harness, depending on the connectors people want.

Great pricing

bmwman91 · « **Reply #73 on:** July 13, 2011, 06:23:18 PM »

Good to know. As someone that wanted a MAF conversion for YEARS, I know what seems reasonable & what doesn't. The two companies we all know of that make MAF conversion products have pretty steep price points. It always put me off. For the most part, I am trying to target the price of a rebuilt M42 AFM.

I want to make sure I am up front about the total cost though. The converter is $200-$220. The sensor & "making it fit" are not part of the package at the moment. A new MAF is like $120, and a lot less used. "Making it fit", at its basic level, will take a cone air filter.

So the big question is "When can I make a Purchase? "
