Comparison pics between Arduino Mega 2560 and Arduino Mega Pro. These controllers can operate your car! The first pic illustrates a...

Hard to imagine that the Spark Gap X4 ECU has most of the features of an OEM ECU. Technology has been busy. Edit: The size is so much...

Had trouble getting the Arduino MEGA Pro connected to the Speedy Loader and Tuner Studio. Tried different cables, looked for comm/USB...

Going to be off line for a bit, will check the forums as I always do, but won't be posting. Have other projects that need to be...

Dave0430 is correct in where the MAP connection has to be. To use a sensor in the plenum area, it would have to be a mass air flow...

The MAP has to be connected to the engine side of the throttle plate to get manifold vacuum. The plenum is on the wrong side of it and...

Tapping into the air plenum would not be my preference primarily because the plenum is too far from the engine cylinders to provide a...

Next discussion item is the manifold absolute pressure (MAP) sensor. Do you really need this, yes. It is the backbone of an EFI system...

Spark Units, aka Coil Drivers (CD) and coils are my next discussion items. Coil driver9s) are required because the OEM wasted spark...

Taking this installation piece by piece. The next component to discuss is the crankshaft trigger wheel and sensor. A recommended...

Time to put the fuel issue to the side and look at the EFI ignition only installation, and we’ll start with the carbureted 1200 GW...

Good morning Dan. The short answer is the fuel pump does not use a pressure switch, and pressure is regulated by a fuel pressure...

Good morning Dave. Thank you for commenting; however, the information I have provided is from the Electrical Troubleshooting manual...

Side trip - new ECU microprocessor is an Arduino Mega 2560. There have been some technology developments. Have been looking at a...

Let’s take a. side trip and discuss the issue Safety, personal and equipment. Not going to spend a lot of time on this because a...
