Alright, so I've decided to replicate what youtuber ThunderHead289 is doing to his Ford 302 with a lawnmower carb and an 02 sensor based electronic fuel ratio balancer that actuates a vacuum leak.
In order to do this I needed access to the ignition timing of my civic because it's the first year to run electronic ignition, I decided to go with Speeduino for this with the hope that it can also handle the fuel ratio balancing based on the output of a AEM wideband UEGO O2 controller by actuating a servo attached to a butterfly valve that sits upstream of the carb inlet (formerly the EGR port)on the AEM intake pipe, a bit like a choke but it would be used to lean out the mixture from the carb or to sit wide open when in normal EFI mode.
I'm also hoping I can turn off the electronic injection in software while the carb is set to run.
Ordered:
Assembled 0.4.3c with VR conditioner, DVR8825, Mega.
AEM 30-0300 X-Series Wideband UEGO AFR Sensor Controller Gauge.
Parts on hand:
AEM intake pipe with K&N filter
Ford Escort Throttle body butterfly valve that fits K&N filter, (will need 3D printed flange to pipe adapter, will need way to mount servo motor to position sensor mount).
A couple servo motors from 3D printers.
Tiny Briggs & Stratton carb about the size of a bobba straw.
Parts to order:
46psi to 2.5psi pressure regulator
Adapter fittings needed to split the fuel line from Honda and go to regulator.
Shut off valve for carb, electronic control would be sweet.
12+1 crankshaft wheel, not sure where to order this
Either a OBD2C compatible Speeduino pinout to ECU adapter or a dead/used ECU to rip apart.
Let me know if there are other bits I might need. Yes I'm aware this is stupid, I'ma do it anyway.
My goal is ecomodding with the option to easily switch to EFI when power is needed. The car is a bit of a junker but I got it to start and it seems to run fine, 5speed, 2 door coupe body. I like to go down to the creek so I'm also fitting 215/70r16 offroad tires under a 2in lift. Lol
