Hey guys,
ive been planning on using the uncut 1uz harness from a 92 ls400 untill i saw an artical on lextreme.com written by the guru of 1uz swappage Phil bradshaw that states
"The 90-92 LS400/SC400 ECUs seem to be a problem child for some reason – these have 4 x two-row grey plugs and I have had about a 30% success rate with them so far. They all start and idle ok, but for some reason many won’t rev beyond about 2800 RPM. I do not know hwy this is – it makes no difference whether the loom was cut or intact, whether the auto trans is there or not. I wonder if the missing traction control is part of the problem, but it doesn’t affect any other ECU. "
is this just old info?
is there a cheap, if not free work around to solve this issue?
are any of you running a 90-92 ls400 ecu with a manual trans currently?
Im at the point where i need to decide what ecu to use and the crown ecu he reccomends is impossible to find in the states.... er... impossible or expensive... i forget what one....
