Hardware table tracing is a function that allows you to keep track of which areas of memory the ECU processor is accessing. In other words, you can observe the coordinates in the maps of interest, according to which the ECU is working at a particular moment in time. To accomplish this, this function is supported in TunerPRO RT.
In this article we will talk about tuning ECUs Motronic (Bosch), GM, DSM (Mitsubishi), Jetronic, etc.: BMW, Audi, Volkswagen, Volvo, Chevrolet and not only, with external EPROM memory: 27c128, 27c256, 27c512, 27f512, etc. This is a relatively outdated ECU cars 80-90-ies. Many tuners will say that the ECU data is not "chipable” or setting up ECU data is very difficult, and the best solution is to install a "sports" control unit such as MegaSquirt, Vems, AEM, Haltech, etc., but due to the hardware primitiveness, fortunately, there are currently ways for these cars to fully configure online. For this purpose, there are memory emulators that allow you to detect the memory chip with the ability to change the memory dump (ECU firmware) in real time using special software for editing calibrations. The advantages of setting up a standard control unit, as opposed to installing an external one, are: maintaining a standard diagnostic system; no need to replace or rework standard wiring; no need to replace or supplement sensors; no need to coordinate on-board control units with the engine ECU.
The implementation of a new revision of real-time emulators CobraRTP R4 + has begun!
This revision of all versions of the CobraRTP emulators has significant improvements in comparison with previous versions, namely:
- Complete absence of additional power sources (batteries).
Starting with revision R4.0, all versions of CobraRTP emulators have a more advanced memory type (NVRAM). Of course, this significantly increases the level of reliability and practicality of the device.
- The outdated 8-bit AVR processor has been replaced by a modern, much more powerful 32-bit ARM processor, with the transition to which some performance and compatibility issues with individual ECUs have been resolved.
- Reduced dimensions of the printed circuit board, due to the use of a smaller overall element base and also due to the absence of a battery.
This is a powerful feature that allows you to track data in real time without the need for third-party equipment.
With this function you can observe the working cell on the calibration card (table) in real time, i.e. you can see where from the table the ECU reads the parameters at real time.
This greatly speeds up the tuning process and brings clarity to the ECU tuning process.
Also, with the help of this function, the level of self-learning is increased, and a person who is not an expert in this field can quickly understand the basic principles of setting.
