okay everyone, my bros got an ECU with a "Suzuka esprit" sticker on it, i have opened it up but i cant see if there is a chip or not because the upper board thingy has a screw with a knackered head. Anyone heard of the company? and anyway of telling it is chipped without taking out that upper board thingy?

 

Also have a HKS F-CON V piggyback ECU which was on my brothers old Zed but there is a sticker on it (from factory) with ECR33 (some japanese writing) RB25DET. Any ideas as to why it is there?

 

oh almost forgot at the side opposite where the wires go into the ecu is a little screw type thin which has japanese wrinting on it, you cant twist the screw two ways but it doesnt come out, can anybody tell me what this is?

The screw is for putting the ECU into diagnostics mode - causes light on dash to flash.

Not heard of Suzukz esprit, but there are loads of tuning houses in Japan, its almost certainly chipped - no other reason to put the sticker on it. Its always best to replace Japan chipped ECU's with a UK remap though as it will be most likely mapped for higher octane fuel than what we have available here.

 

Sounds looks like somebody has adapted a HKS F-CON Skyline R33 GTST version to work with a zed using a Z32 harness. Presumably purchased 2nd hand and then got the Z32 harness to make it work.

i heard of that before so thats probably right ^

thanks guys
