Hello.
I’m brand spanking new here, and looking for assistance.
I’m looking to build a semi-simple circuit/module that will combine the outputs of 2 Mass Air Flow sensors (MAFs) and average them for the ECU.
It’s for a simple electronic fuel management piggyback device.
Basics are:
Two MAFs, two turbos, common plenum, and fuel injectors with exactly twice the stock flow rating.
By splitting the MAF signal in half (effectively) the ECU cuts the injector duty cycle in half (so fuel flow matches what it should be for the given amount of air flow)
I Would also like to have an output adjustment (+/-20%) for tweaking.
I found this thread:
https://forum.allaboutcircuits.com/threads/averaging-two-0-5v-analog-signals.9620/
It starts out good, but gets overly complicated toward the end by addin other components.
I just want to alter the ECU inputs to get the desired result, like we’ve been doing for years.
I’m a fabricator, not an electrician, but I can read simple schematics and build circuit boards. I’ve built many turbo setups, and used a multitude of different methods to control the mixture (FMUs, rechipped ECUs, Apexi Super-AFCs, aftermarket ECUs, etc.) I feel the factory ECU is the best controller out there, it just needs fooled a bit (or byte! Lol)
Thanks in advance for any input!!
