Ren Hoek Posted April 26 Report Share Posted April 26 Hi, I am currently running a Vipec plugin ecu in my 1996 V1 wrx sti. I have run this ecu in the car over 10 years and all works good. My question relates to the stock dash. I am wanting to remove the stock dash but notice that when the wiring connector at the rear of the dash (the one closest to the right hand door) is unplugged from the dash, the engine begins to misfire at idle. Any advice on what causes this and best way to remove the dash and have no miss? It’s like the ecu is not happy with something, like a missing input. thankyou.

Adamw Posted April 26 Report Share Posted April 26 There should be no dependence on the dash being present. The only 2 connections to the dash are tacho from ecu to dash, and speed signal from dash to ecu. Neither should cause a misfire. I would suggest doing a short PC log with the engine running and unplug the dash so we can see what else changes in the ecu when you do that.
