Hi there, i have a 93 vr4 with pte 550s and a chromed ecu. Ive been trying to get my mid fuel trims within range and had a few questions:
Upon research, i found everyone stating the pte 550s do not flow what is advertised and is usually a lot less.
I began my flash with the normal 550 scaling and latency info from pte posted in this forum. My mid trims were pegged rich (-12.5%) front and rear. I scaled them up to 575 and it has brought them up and usually settle around -7% on front and rear with the banks always within 2% of each other.
Should i keep scaling up or should i start looking for another problem? I have the stock fuel pump and pressure regulator with the fuel pump resistor bypassed.
Any insight would be wonderful!!
Thanks!
