MPPS v18

Bogdan — Mon, 07 Sep 2026 09:17:06 +0000

MPPS v18 (Multi-Performance Tuning Suite) is a standalone ECU (Engine Control Unit) read and write interface for chiptuning, designed for automotive technicians and remapping enthusiasts. The tool allows reading and writing flash memory / EEPROM directly through the OBD2 diagnostic connector.

Key Features and Technical Specifications

Automatic Checksum Calculation: Includes automatic checksum calculation for supported engine computers (such as Bosch, Marelli, Delco, Siemens), preventing ECU lockout during writing.
Tricore & Boot Mode Support: Allows working in Tricore Boot Mode (for microprocessors TC1762, TC1766, TC1796 etc.), useful when rewriting through the OBD2 port is blocked or unavailable.
Automatic ECU Detection: Automatically identifies the computer type and processor model upon connection.
Extended Compatibility: Covers a wide range of petrol and diesel vehicles, especially European brands (VAG Group – VW, Audi, Seat, Skoda, as well as BMW, Opel, Fiat, Alfa Romeo).

Main Uses

Chiptuning & Remapping (Stage 1 / Stage 2): Reading the original file from the ECU, modifying engine maps and writing optimized software back to the computer.
Special Software Modifications: Cancelling or modifying error codes (DTC), DPF, EGR or Immo Off for motorsport-oriented vehicles.

System and Hardware Requirements

Housing and Connectivity: OBD2 cable on one end and USB connector for laptop on the other.
Operating System: Works optimally on Windows 7 (32/64 bit) or Windows 10. Manual driver installation from Device Manager is recommended and temporary antivirus deactivation during installation is suggested.

Writing Caution: During the reading or writing process on the vehicle, battery voltage must be stable (connecting a quality rectifier is recommended). A voltage drop during writing can permanently damage the engine control unit (ECU).

Rev Counter Signal Converter

marius — Tue, 07 Jul 2026 15:55:21 +0000

After a change of engine (Engine SWAP) or dashboard clocks (cluster) on your car, you may notice a different rev range (RPM) on the rev counter.
This control box allows you to solve the problem very simply, just by selecting some switches (check the table in the photo).
As can be seen in the second photo of this ad, our control box has 4 small switches inside. You just have to choose the desired positions of the switches, depending on the application you need.
For example: if you originally had a car with a 4-cylinder engine and installed an 8-cylinder engine, you will have 2000 rpm displayed on the rev counter when the engine is running at 1000 rpm. Our control box will solve this problem!
This control box is very easy to install. You only need to connect 4 wires, as explained in the instructions included in this sale.

ZF 8HP CANTCU Display – 1.5 inch

marius — Tue, 07 Jul 2026 15:54:09 +0000

8HP Display Description
1.5” OLED display for the BMW 8HP transmission. The display connects to the CAN wires and reads the data stream from the transmission controller (and from the ECU in some cases). The display is programmable for CAN addresses and speeds.
These are configured for CANTCU at 500kbit. All of these settings can be changed by you after installation, if needed. If you’re not sure of the CAN speed, it is typically 500kbit for BMW ECU-based builds and most aftermarket ECUs.
Please note that this item is a simple display meant to be integrated into the dash, etc. If you need to mount it in a 52mm gauge pod or on the dash, you will need a bezel, which we sell separately.
