Describe the build, get the I/O tally, shortlist the ECU, plan the pins. Free, in-browser, nothing stored.

The planner runs entirely in your browser. Nothing you type is sent anywhere, and nothing is saved between visits — export or print your sheet before you close the tab. If a pin looks wrong for your ECU, tell us which one; the profiles are transcribed from manufacturer manuals and corrections are welcome.

Always verify against the manufacturer’s manual and your tuner before wiring.
