ChampCar Tech Desk

Official channel for ChampCar technical questions, interpretations, and VPI requests.

Before you submit a ticket

The Tech Desk is for rules clarifications and technical questions. It is not a post race tech line, a place to protest results, or a place to fish for how other teams built their cars.

Most questions can be answered by reviewing the current BCCR Rulebook. Please read the applicable section before submitting a ticket.

If your question is already covered clearly in the BCCR, your ticket may simply be answered with a reference to the rulebook section.

VPI request checklist

For all Vehicle Performance Index (VPI) requests you must include:

  • Year, make, model, and trim level
  • Engine size and engine horsepower
  • Drive type: FWD, RWD, AWD, or 4x4
  • Transmission type: automatic or manual
  • Car weight and all factory options that affect performance
  • A link to the vehicle on automobile-catalog.com or another site with full specifications if it is not listed there

Requests that do not include all required info and research will be denied without review.

2023-02-25 - Timing wheel, ECU & Sensors

Q:
We have an MS3 Pro PnP ECU. We had to install a 36-2 timing wheel to replace the OEM 4 tooth timing wheel. The reason for the timing wheel is that it increases resolution over the OEM wheel and allows the ECU to better see what the engine is doing.

We are viewing the timing wheel as part of the ECU system. This would indicate no penalty points.
What view does CC take on a non-OEM timing wheel?

A:
ECU & sensors are free so the trigger wheel is included..
