[QUOTE="seech, post: 420377, member: 4572"] I acieved mine by having a lighter right foot. :-) Actually I did not know the ECU was faulty until I started to have problems. The 1J felt underpowered, lots of black smoke under boost, uneven idle, slight misfire, etc. Basically signs that it was running rich. Fuel consumption gradually got worse from around 350km per 50 liters to 300km. Thought it was MAP sensor but upon further investigation there was a short on the ECU board. My mechanic sourced for a used one and on the first test drive it was much, much more powerful. No more smoke also and much improved fuel consumption. So far on easy driving in town can get around 400 mm per 50 liters which is about the same as my old M50B20. Good stuff. [/QUOTE]
