Tuning Tips

PiDash by Pahls Performance is a RaspberryPi based digital dashboard display that runs TunerStudio. In additional to allowing you to customize your dash and gauges, you can also tune your engine straight from the dash using a keyboard and mouse, or in some models touchscreen capabilities. The PiDash requires minor wiring for a 12v power…

Greg Banish, Calibrated Success Idle tuning and control often seems to be an afterthought on some tuning projects. The devil’s work, it seems. Worse some try to do it too soon without nailing other important aspects of the calibration and get hellish results, only to curse the controller. Proper idle tuning and control can be…

Many engines from the 1990s and later already have enough sensors to fully support sequential fuel injection. But what if you’re converting an older carbureted engine to EFI, or want sequential injection on an engine with an early bank to bank EFI system? Sometimes, you may be able to get an easy bolt-on solution from…

The relay board has an onboard fuel pump relay that will work for smaller fuel pumps. The Walbro GSL392, for example, will work fine at normal fuel pressures. We used one like this on our Chevy Nova project. But if you’re running a bigger fuel pump like an A1000, we recommend avoiding running the current…

Things you shouldn’t power from the fuel pump relay

Posted on March 22, 2019

The fuel pump relay (or a second relay wired in parallel if you are worried about too much current) can be a handy source of power for other devices. The fuel pump relay can help isolate noise from coils and injectors from the main ECU power. And powering a wideband O2 sensor controller from the…

The MSPNP Gen 2 does not have as many analog inputs available as its big brother, the MS3Pro PNP. However, you can add an analog input with our jumper.1 kit if you are willing to give up the barometric pressure sensor or knock sensor input. No soldering is required. To carry out this modification, remove…
