Hey so ive always been wondering what type of chip I have on my e30. The previous owner says I have a chip that requires 91 octane fuel. It made sense because my redline seemed abnormally high. So yesterday while installing a non-broken glovebox I decided to pop the ecu open and check it out. Looks stock to me? The guy worked at a tuning shop so is it possible to just flash the chip?
So after reinstalling it, i went for a test drive and all seemed well. But this morning on my 20 mile commute the car was acting retarded every 2-3 minutes of cruising at 65 mph the car would cut power and flash the check engine light super fast (less than half a second). Whats up? Did i mess it up? or the harness that attaches to it? Do i need a new dme? or could it be a fuel filter/pump/spark plug/wire issue?
