The Project Pad

Made it down to get fresh fuel and back.

Seems like my known 440cc tune from when I parked it 18 mos ago is way rich at idle. Not sure why I'd have more fuel today, I may have been on the summer E85 back in March of 2013.

So I have an interesting theory, I think my fuel line was bleeding pressure for a while.

The only things that have changed since I stopped daily driving the care are:

1. I reattached the fuel line to the barb on the pump (backflow valve) with a clamp
2. I got E85 from a different station

Now my idle cell wants ~40% of the old value (~25 vs. 55) to be "happy" with the idle screw cranked open, I cannot think of many reasons that I would have basically "gained" fuel at idle.

I am picking up a new 17014 tonight so I can try to sort out the issue with my WBO2 and get things running correctly.

has fuel pressure gone up because of a bad fpr or a pinched return line?
my zeitronix is dead atm . I just got a 17014 for iirc 39 shipped
what wb are you using?
before mine died it was reading richer than actual.

I'll examine the returns, good thought.

VEMS has a wideband on board, I've always used the 17014. I have another thread about how it seems to be an issue with the heat function.

Tired of messing with it, need a snow car, will have an MTX-L WB tomorrow, should pass emissions once I know what lambda is. I'll deal with the onboard sensor in the spring.

Woohoo finally legal again, just in time for some snow starting Sunday!

Sooo... vids are forthcoming, right?
