How to choose an emulator and what is the difference between different versions?
If you have BMW, Audi, GM, Nissan, Volvo, VW, etc. (i.e. Bosch, Siemens, etc.), then you MotronicRT, which is offered in 2 versions - USB and Bluetooth.
If your PC does not have Bluetooth, then you can add to the order USB-Bluetooth adapter.
If you have a Honda / Acura, then CobraRTP v3.0 is available for you. Honda Edition respectively.
There is also a universal version CobraRTP Pro, which supports all of the above ECUs and combines all the functions.
What computer unit (ECU) are supported?
What are the features of this device?
In hardware, the emulator performs the same role in the ECU as the chip in which the ECU control program (firmware) is stored, but with the ability to change the data (firmware) in real time.
Based on this, the emulator will have the same set of tuning functions as the firmware editing application (TunerPRO, Crome, eCtune etc.). This is usually the ability to change the fuel injection (AFR), setting ignition, rev-limit, operating modes Vanos, etc.
Thus, the emulator allows you to unleash the potential of a regular engine control unit, and this can save you from installing third-party ECUs, such as MegaSquirt, Vems, AEM EMS, etc.
In simple terms, the above can be called "on the fly" chip tuning.
The advantage of setting up a control system with an emulator is minimal intervention in the electronic part of the system, as well as full operability of standard diagnostics.
For BMW owners: CobraRTP emulators do not combine the MAF emulator function, and do not provide an opportunity to connect MAP directly to the Motronic ECU! First of all, a memory emulator is a device that makes it possible to configure stock parameters (firmware of the engine control unit) online!
Theoretically, within the framework of hardware compatibility with the ECU, you can connect another DMRV, but this possibility is feasible if there is a possibility (table) to calibrate this sensor for a specific ECU.
Also, the device does not have the ability to switch to coils or the ability to connect incompatible sensors in normal mode.
Do I need to upgrade ECU for CobraRTP?
If you have a Honda OBD1 / OBD0, then you need to prepare an ECU for installing external memory (for a chip), and also prepare a Datalog connector (CN2). How is this done you can see here. This is necessary to obtain the possibility of tuning the computer.
Upgrade and installation in Siemens MS40.1, see here: go ...
For Motronic control units (Bosch), DSM, etc. revisions are not needed. All you have to do is remove the stock chip and install CobraRTP instead
Is the emulator suitable for turbo engines or after installing turbocharger?
From the above - this device has no direct connection with the configuration of the engine, including the turbocharger and its electronic part (valves, sensors, etc.). First of all, it is a device
which makes it possible to adjust the stock parameters (block firmware
engine control) online.
Naturally, after installing the turbocharger, it is necessary to adjust the control system (ECU), and this is the fuel supply, ignition, operating modes, etc. for which the emulator is intended.
Therefore, this question is incorrect, although it is asked quite often.
Is it possible to write ROM to the chip after using CobraRTP?
Yes, it is possible. The firmware is stored in the CobraRTP memory in the same form as in the chip.
Therefore, after tuning, you can simply write the final firmware to the chip using the EPROM programmer. You can get firmware in * .bin format from CobraRTP using CobraRTP Utility.
Is it possible to use the emulator all the time, or is it necessary to write the firmware to the chip after configuration?
Yes, you can constantly use (ride with the device) the emulator, as well as the chip, because firmware is stored in memory
For versions with a battery, the firmware is stored for about 5-6 years due to the discharge of the battery, for versions without a battery (revision r4 +) with NVRAM memory, the firmware is stored for at least 25 years without turning on.
What software (program) for tuning do I need?
For BMW, Audi, Opel, VW, etc. fits TunerPRO RT Is a universal editor of standard ECU firmware that works with various equipment, including ROM emulators.
To work with a specific ECU, you need a firmware (bin) and the corresponding map and table definition file (xdf). All this can be obtained on the off. site: http://www.tunerpro.net/downloadBinDefs.htm.
TunerPRO on russian http://energodar.net/blog.php?str=nexia/chip-tuning/tabl
Also TunerPRO partially in Russian you can download on our site.
For Nissan — Nistune и TunerPRO.
If you use any other editor, for example WinOLS, then using CobraRTP Utility You can quickly download CobraRTP firmware(ROM) online (RTP).
