LPG Tuning
(OP)
I just converted my 86 chev 1/2 ton 350cid 4wd to liquid propane, 425 mixer, model E converter (no computer) I installed a 1 wire bosch O2 sensor, connected a digital volt meter and I can adjust the idle mixture to about .5v, but cruising down a flat road at 50-55mph It runs about .18 to .20v. Under excelleration voltage jumps up to .90v. From my research I understand that it should be at approximately .55v for optimum air:fuel ratio. Shouldn't the air:fuel voltage be aprox .50v at 50-55mph cruising speed? Seems to run really good, but being the perfectionist that I am, I really want it RIGHT. I would appreciate any information anyone has to offer.
