Hi Adamw, Thank you for your response. I have confirmed that the issue is likely caused by the MSD coil. I have attached log before replacement below. The signal for the driven wheels comes from the factory sensor, provided by the speed sensor on the gearbox. The signal for the non-driven wheels is extracted through a frequency reduction circuit from the ABS rear wheel sensor and then supplied to the ECU, so it is not subject to interference. I once saw in the factory manual troubleshooting section that if the factory speedometer behaves abnormally, it is recommended to check whether non-standard resistance spark plugs are used. Therefore, I speculate that the speed signal from the original car may be affected by the ignition system. Additionally, after replacing the MSD K20 Coils, this issue occurred immediately, and it returns to normal when reverting to the original factory coils. Thank you.

Hello everyone, I have swapped my ignition coil from the stock coils to MSD K20 coils, my engine model is Mitsubishi 4G engine, but I still keep the ignition system as a waste spark instead of COP. However, my driving wheel signal is noisy while WOT after the upgrade. I believe it was caused by the MSD coils because, if I swap the MSD coils with my stock coil, the speed signal becomes normal. You could find the log as attached. Can anyone guide me on how to solve this problem? Could I add something to filter the noise from the MSD coils? Thank you.

Hi All. I have pinout questions about the EVO4-8 plugin ECU. Here may some typo in the manual from Link website. For the EThrottle ver1.5. I can see AUX4 at the Expansion Connector1(page 12) and DI10 at pin46 (Page25), but if you use the help function in the PCLink Engine Management software, it shows DI10 at Expansion connector 1 and the there's empty pin at pin46. Which one is correct? This situation also happen at the ver1.3 Page10 in the manual from Link website, DI10 at Expansion Connector1,but in page22, DI10 also in pin46.
