Hello all,
I'm looking to add a standalone ECU to a standard 1993 Mercedes W124 220E with the M111.960 engine. This engine has a MAF sensor and I wondering what my options are in terms of ECUs to use MAF over MAP.
The way I see it I have the following options:
- Use an ECU that can utilise the MAF
- Retrofit a MAP sensor
- Undertake some software trickery on the ECU to read the MAF
Thanks in advance.
hi,
almost all modern ecu will have MAF and MAP.
if i where you to make it simple, i'll switch to MAP, 2min job [=
You can use the MAF but honestly what is the point?
Just use the MAP unless you want a more complex load calculation.
I often see factory ECUs which switch from the MAF at an RPM point to the MAP. They do it from emissions.
With the 960 do you even need a MAP? You could run it Alpha N
Off topic, haven't worked on an M111 in years. I had an apprentice that did an exhaust gasket and dropped a bolt in to the inlet next to it. put me off them lol
I've used MAF on Link ECU. Once in a while you run across an application where it makes sense to do so.
That said, as the others mentioned switching to a speed density model is certainly the more common path when installing a standalone ECU, and there's likely a reasonable way you can fit a MAP sensor to that engine.
