FAQ

What is the difference between the PST and PS-AA sensors for MAP measurement?

The PS-AA measures pressure only and outputs a single ratiometric analog signal. The PST sensors (PST-1, PST-3, PST-4) measure both pressure and temperature from the same port, outputting two simultaneous ratiometric signals — one per parameter. Use PS-AA when your ECU has a separate temperature sensor for the same circuit; use PST when you want to reduce sensor count and plumbing complexity.

Which Bosch lambda sensor is compatible with my wideband controller?

The LSU 4.9 (SKU 0258017025) is the standard wideband sensor used by Bosch CJ125/CJ135 chips and virtually all ECU-integrated wideband controllers (Link ECU, Emtron, ECUmaster, AiM). The LSU ADV and Mini-LSU 4.9 variants are not currently stocked — contact us if you need those. For full LSU 4.9 connector pinout and calibration data, see the LSU 4.9 product page.

What is the difference between the DF11S and Mini HA-P speed sensors?

The DF11S is a current-loop (4–20 mA) passive sensor — it cannot be wired directly to a digital input on a standalone ECU without a signal converter. It is designed for the Bosch ABS M5 modulator and works natively with Bosch Motorsport displays and data loggers. The Mini HA-P is an active Hall-effect sensor outputting a digital 5 V square wave directly readable by any ECU digital input. Use Mini HA-P for crankshaft, camshaft, or wheel speed inputs where a standalone ECU is the receiver; use DF11S for Bosch ABS systems or with Bosch Motorsport data acquisition hardware.

Which IMU should I choose — MM5.10 or MM7.10?

The MM7.10 measures 6 axes: 3-axis linear acceleration plus 3-axis angular rate (roll, pitch, yaw). The MM5.10 measures 5 axes: 3-axis linear plus roll and pitch only — no yaw rate channel. If your ABS, traction control, or data analysis requires yaw rate (most active vehicle dynamics systems do), the MM7.10 is the correct choice. The MM5.10 suits applications where yaw is derived from other sensors or is not required.
