Here’s an update on some of the work that has been going on lately. We’ve been quite busy with lots of new development, and will be posting more frequent blog updates in the near future.
Bosch TMAP sensor input to a stock ECU
We’ve managed to get accurate MAP readings into a stock ECU, streamed back live over the diagnostics port! This is a 3-bar Bosch sensor connected to a 10-bit analog input on a stock ECU, capable of reading of Manifold Absolute Pressure and Air Intake Temperature. This setup is accurate to ~0.3 kilopascals, and we’ve verified it stays accurate under vacuum and 2-bar of pressure.
These readings reflect what is observed by the local weather station and are typically within 0.5kpa.
