What I plead is this....my income is around 10K/yr. I cannot afford to screw around with cars that don't stay running or have a gas cap in the shape of a turban. I look at things this way: the cost of both items is equal to 12 gallons of gasoline. If my ECU should go open loop 12 gallons of gasoline is a laugh-a-minute. I would use the needle dropper D100 and drizzle drop-by-drop enough D100 to stalagmite it's way down that'll pin onto the board. Your option of course is to meet the deliverman and sooner or later you might get a "rebuilt" ECU that doesn't catch fire.
