Reflashing an ECU can void warranties, reduce the vehicle’s reliability, and cause a whole variety of undesirable consequences.
The ECU is a safety-critical system in a car. There are several important points to be aware of when using Nisprog: Open source ecu tuning serial#
These are the “Generic dumb serial adaptors” described in the freediag docs.
Connectivity: a simple USB-OBD adapter is required. Open source ecu tuning code#
OS: Linux and Windows are known to work Nisprog is based on freediag source code which is cross-platform and should run on most Linux/UNIX flavors. Unfortunately CAN-only ECUs are not currently supported. K line wired to the OBD-II connector pin 7. SH7055 or SH7058, 0.18um microcontrollers (the most common types). The basic reflashing kernel will support gasoline ECUs with: Fast ROM dump (tested up to 5.4 kB/s typical speed is ~100 B/s without a kernel). The basic kernel is an implementation of an ISO14230-compliant protocol with extensions. Reset the ECU: the new firmware will now be executed, and the kernel will be completely removed. Send the reflash commands and new firmware data to the kernel. From this point on, the kernel runs from RAM and effectively takes control of the whole ECU. Send the first stage data payload: this is the “kernel”, a simple program that will receive commands and data for the reflash. Recently, the necessary commands have been reverse-engineered revealing the required steps: The process is carried out entirely over the OBD-II “K Line” serial communications link through an undocumented set of manufacturer-defined extensions to the standard ISO14230 protocol. This project supports ECUs that use the OBD-II “K line” signal for diagnostics communications. Most gasoline Nissan / Infiniti ECUs from ~ 2002 onwards share very similar ECU hardware, based on SuperH microcontrollers manufactured by Renesas (previously Hitachi). If the ROM size is 1024K then you use the 7058 kernel.Ĭars Tuned on ROMRaider / Nisprog 5.5 Gen Maxima Tuned by AdminTuning VQ35 Bolt Ons Shaquille Jenkins 5.5 Gen Maxima Gen2 VQ35DE Trevon Walters 4thgen Maxima Hits 11.77 (All Motor) Gen2 VQ35DE Which ECUs Will This Work On?

Since you’re modifying the ROM yourself, there’s no vendor lock-in and you are free to do what you need and want. The average tune costs roughly $600+ these days. For all you hardcore Nissan/Infiniti enthusiasts, there is finally an open-source solution that allows you to modify and flash ECUs! With a $10 VAG-KKL cable, you can basically flash your own ECU and tune it your to personal comfortable without breaking your wallet.
