I am located outside of usa. Doing a l67 into a older car that runs, i think its referd to as a l27 gm 3.8 at the moment on delco ecu.
I will be running a gm 2 bar map sensor and can get most of the stuff running.
But i dont have a timing map to use ?
I know their is a lot of variables.
The car will be running 91 octane unleaded fuel.
Standard boost pulley.
Ive googled a heap and see people saying these engines can take up to 40 deg at low cruise speed etc etc.
But yeah not much else mentioned.
Dose anyone have a decent timing map that i could use that could get me going?
Any help will be appreciated
thanks
