Hello everyone! Sorry I'm late but i might be able to shed some light on this topic!
I'm building a Onevia, having owned my Silvia for a while, and a 4door R32 as well (hense why I'm a member here!) As time passed, i thought the old natro Silvia needed a rebuild, and when I sold the R32 I also got a 180SX donor car as a part of the deal. The car was written off, but the front end was good, so the panels and black-top SR20DET /gearbox /ecu and loom etc, was all intact. The car was only in the country for two weeks before being hit by the Kia, so nothing had changed from when it came into the country to when it got to me.
Having been stripping it apart, i found a switch hidden in among the wiring at the back of the dash. Having traced the wires back to the ECU i found this;
I'm a parts interpreter, and i've seen ecu's before - standard and aftermarket, but not one with a switch hanging out the side of it hahaha. Once the motor goes in, I'll take it to by brother in law's work and plonk it on the dyno, maybe we'll find out if it's rev/speed cut removal or something else
Dont mean to hijack, just stoked to find out i'm not the only one scratching thier head hahahha
