Right, I have recently purchased a very cheap LS400 and it's exhibiting all the signs of a bad ECU.
Stuttering at full throttle, cluster isn't showing speed or rpm. Throwing a 31 code for the TPS.
Thing is, the guy I bought it off had the ECU 'repaired' and when I had it looked at by an electronics guy who apparently repairs these ECUs he said one of the chips was missing a leg but the capacitors had been replaced.
Guy repairs the broken leg on the chip. I put the ECU back in and I'm still getting all the symptoms. Still getting the TPS code.
The TPS is good, I checked the resistance. Before I go in search of a new ECU does anyone have anything else for me to check? Can the cluster being fucked cause any of this?
Where can I find a manual or pinout for the 89661-50160 ecu? I'm struggling to get the toyota manual in PDF the one listed as xf10-20 89-97 is actually a 2000 with a 3UZ so does me no bloody good.
Also finally any one got any info on ECU interchangeablity? The 89661-50160 is UK only and only for 1993 making it annoyingly rare.
Thanks in advance.
