MEGASQUIRT INJECTOR DRIVER

However, you can't really compare the throttle of an EFI throttle body to the throttles of a carb. The other parts could be left on the board if you are not going to use the DB37 pins for the injectors. You can remove the remaining flyback components if you wish. If you have an adjustable fuel pressure regulator FPR , set the pressure with the fuel pump running, but the engine not running - that's your base fuel pressure it is referenced to atmospheric pressure. An ideal idle duration is around 2. The result is little or no accel enrich when the engine needs it most.

You can remove the remaining flyback components if you wish. I took the car for a short ride around the block and the engine was still rich until I believe I was nearly back home The AFR would sit about Number of Injectors Horsepower 1.

Megasquirt Fuel & Injector Managment - Miata Turbo Forum - Boost cars, acquire cats.

Most injector systems will use one or more fuel rails. This is the schematic for the FlyBack board: Often the engine will run with lower values, but will not have enough voltage to re-start.

Your engine will need a certain amount of fuel to run correctly at idle when fully warmed up. Tunerstudio will not remember your thermistor setting; however the megasquirt will.

My idle is a little rough though at rpm at stoich. The V3 main board has the flyback circuit built in. The accepted conversion factor between these depends somewhat on fuel density, which changes with formulation i.

What symptoms could arise from that?

Peak&Hold Injector Driver Board for Megasquirt

The board slides in the first slot in the case. The wire going into it is about 14 gauge, so it should be capable of handling megasqyirt full current of the fuel pump. However, do not install injectors with a much larger flow capacity than you need.

You need to find out why. Here are two TBI injectors. Mark the case and drill the holes.

If you have an adjustable fuel pressure regulator FPRset the pressure with the fuel pump running, but the engine not running - that's your base fuel pressure it is referenced to atmospheric pressure.

Niehoff has individual injector connectors under part number connector and sealing boot.

To save a bit of calculation, you can enter your engine's estimated brake horsepower at the flywheel and the total number of injectors in the form below and press the "Compute Flowrate" button.

This shows how to connect the board. The following is a guide as to whether you need to use resistors or the flyback board:. Internally, megasquuirt pockets are contoured to accept the bottom sealing O-ring of a standard injector.

The thread discussing the board can be found here. I am using cc rx7 turbo injectors with the purple top. The current BOM is here.

ID1000 data for Megasquirt from Injector Dynamics

This can be avoided by using resistors in series with the injectors, and disabling the pulse width modulation PWM. Be careful not to 'pinch' any of the connecting wires between the two halves of the case megqsquirt you reassemble.

If you are doing such an installation leave these unpopulated. If you were to megasqiirt off' the manifold vacuum port on the fuel pressure regulator, you are reducing the dynamic range of the injectors. It was at a pretty constant.

These are available from most aftermarket speed parts suppliers, such as Summit Racing or Jegs. Low impedance injectors generally below 3 ohms require some form of current limiting.

I have onjector required fuel set at 5. It has the same features and components as the V1.
