settling in with lc1 & DFA
got the lc1 to feed its signal to the b1s2 O2 sensor but needed to pipe it thru a 5M resistor to keep the P0420 code away(s1 & s2 have identical signal), knocking the signal down, couldn't see the diff on a meter, fluctuates big time. Seeing some good numbers on fuel flow idle noticeable lower at times. can get numbers no higher than the best posted without o2 and the dfa map enhancer still. absolutely must need MAF controller, planning to add some resistors to the ECT & IAT. Fuelsavers freq MAFe doesn't work on GM freq based maf, still looking. I think I am low on HHO output ~1lpm on 3l v6, needs 2. planning a fuel heater, darn Buick has 2 lines=2 heaters. Be nice to do some water injection. Have some weird moments on warmup, AFR climbs ~20+, fuel flow climbs +20%, MAP climbs even though an enhanced signal, idling rough. gonna build another wetcell, sure aint dropping another 2-300.
found another make of freq MAFe, magnumtuning.com, checking it out.
my personnal log on the Buick
Wow, was running my old O2 sensor heater to kill the P0135 light I got with the LC1 doing the narrow band sensor duties, must've got wet, shorted out or something. finally figured out I needed to just run a 10ohm resistance. So I took a cue from http://www.searcypress.com/fuelcell/index.html which advocate running the HHO thru a coil. I compromised on a 18ohm coil. works, ECU/PCM likes it, mileage at 15% increase. Also need to wear a tinfoil hat when driving:rolleyes: gph is at lowest ever on idle!!! .32 this AM and ECU just starting to settle in its new error free environment.
