As most of you know I own a ep91 starlet with a 4e-fte (ep82 gt starlet) motor sitting inside of it. Anyways I am running the stock 4efte computer in the car and the whole wiring harness was a custom job (ep82 matched to ep91).
To the point I always thought high boost was 6psi and once motor put it had it checked and was running 6psi. But now i found out the proper settings and high is meant to be 9.5psi, so my car has always been runing on low! might explain a few things...
Anyways, how can i make a switch of my own (think leftovers from harness have been destroyed) to get the car running high boost and if possible switch between the high and low settings. Just keep in mind that the harness is ep82 matched to ep91 harness (half and half) and running stock 4efte computer...
thanks in advance people, hope someone can help so i can get the car going harder
