Ehybrid:
Vehicle Make: Mitsubishi
Model: Space Wagon / Space Star / Carisma (1998-2003)
Trouble Symptoms: Misfiring, Loss of power, Damaged/burnt coils, No start.
Cause: Most common failure is getting burnt coils. No start may be due to water flooding or bridged wires in the car.
Resolution: If it has been determined by a competent auto tech that the ECU (brainbox) is faulty, the options available are:
1. Change engine, brainbox, and modify wiring (re-wire): this is the most expensive solution and seems to be the most common option given to the car owners by auto techs.

2. Change brainbox, immo box, and key: this is a cheaper option recommended also. The ECU, immo box and key set for you model may not be readily available but patience and diligent search has paid of for some.

3. Buy a replacement brainbox with same part number and match ECU to car: this was shied away from because the immobilizers of these cars could not be synced with a used ECU from another car. Syncing of these model years is actually possible.

4. Repair the defective brainbox: within the brainbox, there are transistor drivers for the coils. These drivers get shorted when the coil goes bad for any reason. Once shorted, replacement of the initially bad coil is of no use as the faulty drivers will burn/damage the new coils. A competent electronics tech with some auto wiring knowledge can identify and replace these drivers in the brainbox. After the driver replacement, simply plug in your brainbox and enjoy...no immo syncing is required for this option.

NOTE: For options 2-4 above, ensure the defective coils are replaced with good ones, else, they will damage the repaired or replacement brainbox.

Here are some pictures of these class of ECUs

Good evening guys. Please I need help with my car. I drive a Peugeot 206. Since this January, 2024. My car have been misfiring, loss of power while driving like throttling to get power but the car will lose power instantly, but once you turn off and turn on the engine, it will regain power again and speed up. This experience can be very frustrating. I took it to my mechanic cum technician who chorused that the fault is fuel pump. I bought same n changed fault persisted. Brought the car back and he said is nozzle. I bought nozzle and changed, yet same problem. He later advised me to change my brainbox with BSI which he tagged at 100k.

Any suggestions on what might be the really issue. Thanks

Please nairalanders help me. My Corolla 2007 started having issue with the gear after changing the gear, the mechanic noticed the car smoking and advise we change or ring the engine . After ringing the engine, the car stopped working properly and then stopped coming up. I was advised to change the brainbox which I did but the car has still refused to come up. Please help me. The rewire guys are just telling me stories and I am totally confused.
