164 24v stock ECU & ? other AFM

[CorseChris]

Didn't think we where trying to design an ECU Barry, just wondering if the hot wire AFM could be adapted for use with a flapper type ECU. Aftermarket systems are many and varied of course, and a different topic entirely. The text on that website implies certain hot wire AFMs output an analogue voltage, but either way, if we can get the output characterisitics for both types in question, then a converter isn't that tough a job. Personally, I've no interest other than helping out, as my car runs and aftermarket system in Alpha/n, with MAP coming along as soon as I install the blower. MAP sensor is alrady installed in fact. The ECU I chose offers boost control in each gear, launch control, flat shifting, etc etc etc. Most of which I probably won't ever use. Our profiles (Jimmystratos & mine) don't indicate we are UK based, so I don't see us opting for a US product anyway, as support over here might be a bit lacking. Thanks for the thought though

I do not know what the montronc is but the L-jet has the map in the AFM
it is not a pot. it has a bunch of LASER trimed resistors that are selected one at a time as the flap moves.

but I have to say reworking and pigybacks systems cost more or as much as a new programable ECU. I would only go that way if you need the OEM for smog inspection or somthing. I guess there is somthing for plug 'n' play if you can not work with wires.

Chris,

Do you have model numbers for the two types of AFM??

[jimmystratos]

Do you know what the numbers you are looking for look like? If you see what I mean?

[CorseChris]

Usual Bosch-type part numbers. 0-1234-5678-9 sort of style. Vague hope that I might be able to track down the specifications for them.

This is a 1994 24v auto ECUhttp://http://www.doctors.net.uk/Doc...x?docid=507954

Ideally need the AFM/MAF numbers Chris...but I'll see if I can find any info from the ECU-end. I do have some car data CDs that might help.

[jimmystratos]

Bosch flapper AFM for 164: 0-280-203-026

[jimmystratos]

And the 156 2.5 Bosch part is 0-280-218-054

[CorseChris]

OK Chris. I'll see if I can find out the specs for those. Meantime, anyone who happens to have this info, please feel free to yell!!
