M20B20 to MegaSquirt build

[garzon]

I was going to ask about the connector... Do you know any way to call that connector? Some hint I could use to find one.

Regarding the MAF, I found this one: SIEMENS 5WK9007 or 1730033, I think it is the same you have. Could you please confirm?

Thanks.

I use a 5WK9605 (BMW 13621432356) with a normal Bosch 3-pin connector.

Yep, thats the same one i'm using. Siemens 5WK9 007.

do you know if it will provide the same readings than the Siemens 5WK9 007? Seems easier to find this one you used at USA -I am getting the sensors from USA since here at Colombia they are way to expensive-.

Thanks a lot.

Probably not, but you need to calibrate it to your own situation anyways. The flow characteristics are different from build to build, so finetuning is needed.

Here are a number of basic functions:

I've used this connector for the 5Wk9 MAF, got them from the bmw dealer:
61131392224 p/n connector
61131376204 p/n terminal

Connector needed a little rework to fit, but doable.

Terminals from a old PC power supply do fit the terminal pins on the maf nicely, with these terminals and leads i did the first tests:

Thanks a lot!! I just found it really cheap.
