P73
I have a p73 ecu and wanted to know if it would be a good upgrade for my 99 SI p2t. I have h/i/e and pulleys cam gears and ctr cams and springs. DOes it have better fuel maps and ignition? Is it a desent ecu? I have a harness and I have pluged it in and it has 5700 vtec 8600 red line it is out of a 98 itr and I am not sure if it is us or jdm.
