Hi guys,

I have placed a 1JZ vvti into my 91 Soarer. I am getting ECT error 89 and its driving me nuts.

Thanks to Wilbo have narrowed it down to

all conditions below are detected for 5 seconds or more
(a)no1 speed sensor. 9kmh or more
(b)mirror check of trc ecu input signal is abnormal
(c)trc ecu input signal does not inform to engine and ect ecu
(d)trc ecu input signal order is abnormal

Its not the speed sensor as it happens with car stationary (although probably will happen again when I do get the speed happening). Guessing its c and d as I can't use the tRC computer (not trc on my car).

Anybody know if its possible to fake being a TRC computer. PRobably just going to have to save for an aftermarket ecu....that can do auto and vvti.....ouch.

Justin.
