So this weened I was working quite a bit and have a bit of idle time in between calls and different tasks so I figured I'll work on the cruiser a bit since I haven't lately.......yes I can't leave well enough alone.
My LX is 97 and was working great. Back in the days I advanced my timing to 8 and it was wonderful even with regular fuel. Fast forward to a few months back I advanced it to 10 degrees and still great but I figure I'll put in premium fuel just in case, it's not my DD.
So yesterday I was thinking, if regular fuel is fine at 8 degree then premium fuel should be fine pass 10 degrees......that's where the story started. I got my trust paper clip and timing light and set base timing to 12ish. Drove around and all is well with no ping or anything, talked to NLXTACY and he thought I have lost my marbles, timing is way too advanced and can hurt the engine. I told him I don't hear ping but he wasn't sure if I can tell from scangauge that the ECU is retarding the timing. So i decided to drive to his place and pick him up so he can help me listen to the ping. I have him, me, 400lbs of tires and wheels and flooring up this 10% hill next to his house. All was well and the cruise climbs with no issues. At the very top of the hill I think I felt a bit lost of power but it was at the very end so couldn't tell.
Happy as a clam I went home but though I should check timing again and see and the time is WAY below 0! guess the knock sensor did work and it did retard the timing. Disconnect the batter for 10 minutes and same thing! I thought if I put in the paper clip I should get my old timing back!
This is where I think I killed my ECU:
puzzled by the super low timing even after battery disconnect I thought maybe the paper clip isn't making good contact. So I unplug the paper clip and try to put it back in and wiggle a little so it gets good contact............and then I saw a spark and engine instantly died.
After looking at the digram the Te1 is right next to B+!!!!!!!! Why is that there!!!!!
after check all the fuses and relays I think my ECU is dead!
Here is where I need your help:
Is there anything else I can check besides fusiable link, relay, ECU A and ECU B?
If my ECU is dead my current ECU part number is 89661-60652, do I have to replace it with the same one or a 89661-60260 can also work?
thanks guys!
