This is my setup in 90 si... b16a2, shaved head, port and polish stage 2, 3 angle valve job.. custom cam, racing clutch, obd1----- p72 ecu----...........

I adjust every thing... tps (4,5 volt), new wiring... i adjust the timing but because my head is shaved... i can't do the best timing.. i buy cam gear and it will be soon installed and it will help me for my timing...

i hear that the p72 will run more rich than a stock b16 ecu... is that true.. and can i play with the tps to adjust the the mixture... ..

sorry for my bad english... i speak french.....
