The bastard at my usual Smog place has decided to commit customer service suicide and simply not help me. First it was the airbox, then it was a gentlemanly request by me to re-re-test today. Nope.
Okay. I've brought 8 cars to this twit and if he feels that not enough to help me for one additional 5 dollar retest, then thats fine. I will find someone else and everyone I have advised to go to this guy will get the message to go elsewhere as well.
Next up will be my visit to a smog referee - as I think there is something fishy from the start.

I will post the new smog failure. Way smaller numbers on everything but the CO

Here is the most recent smog test. At this point, I had 100% E85 in the fuel tank, and had upped the base fuel pressure in an attempt to remedy what is perceived as simply CRAP running at lower RPMS. The stumble still persists, from 2500 to 3000rpm, and the fuel pressure was set at 50psi base pressure.
So with this test, you can see that the catalytic converters do a great job with everything but what is obviously a massive over-fueling (emissions wise) at the lower RPMS -
WHICH I THOUGH would have been remedied by the 02 sensor loop. I thought the higher pressure would make the computer see more fuel (which would help WOT) but then in the 02 loop, it would reduce the pulse width of the injectors. Maybe it simply cannot reduce that enough when the pressure is this high. I'm at a loss really.

This is obviously too much fuel at 15mph and 1800 rpm. But would the 02 loop not reduce the fueling at this point? That number for CO is supposed to be less than 1% with a cat.
I hate the LH system - I really Really do. On the later cars its completely ridiculous how unreliable it is, and overall, it is so utterly temperamental with its unobtainium wire maf, and its finicky temperature inputs.
In response to this, I turned down the Fuel pressure as I said, and will have to retest - on petrol if I have to. I cannot wait until I can use an aftermarket ECU so that I can see and control these parameters.

We deal with the emissions test folks a lot, 2-5 times a week, most of these guys are about two steps away from asking if you want fries with that, and I have found that a five-ten dollar tip goes a very long way once they get to know you.
I tip them every time, fail of pass, they still had time in it.
This guy might not have been making anything off of a retest, just a thought.
PS, awesome what you are doing with your car BTW.![Cheers](https://rennlist.com/forums/images/smilies/beerchug.gif)

I am. But thanks for taking the opportunity for a dig dip**** - I've seen your game before. The fuel is not the issue - as anyone with reading comprehension can see - even with massive overfueling the HC and NO numbers are below average - symbolizing a very clean burning fuel.
CO is the resultant compound that comes from ANYTHING that burns. Wood stove, kerosene engines, diesel, etc. You burn more, you get more of it. I'm doing something wrong here, and part of the issue is that I cannot manipulate the ECU at this time. E85 has been proven to be a very clean burning fuel that has vast opportunities for high-power and high-hp-small-cc engines.

Thanks for your comments Blown. Honestly I didn't think to be tipping him. It didn't even cross my mind, and I did not know this was... normal. At this point, I have to start a new relationship with another smog guy. There IS a 5 dollar retest. I took that retest and failed with this most recent sheet I posted. I went back with lowered fuel pressure and said "Is there any chance we can try this again? I'd really appreciate that"
Nope. Full price. I have been a customer for over 5 years - brought numerous cars - never once failed (well, a S2000 failed with a straight pipe) - so its not like I have abused the retest process.
He wouldn't budge. No interest in helping a semi-long time customer. I bend over backwards for people that spend money with me and from which I pay my bills - and I expect that of others. Maybe I should rethink that later part?

Why not return the fuel pressure to stock, drain the tank, refill with gasoline and try again. Doesn't CA red flag a car if it fails too often?

what would happen if you used an air pump and ran air into the exhaust way up stream from test site on the pipe....would this allow co to change to co2....and thereby lower the co level?

Have you seen the flexfuel interceptors ?
rather than mucking about with fuel pressures and injector sizes which will mess with atomisation and efficiency. These things are supposed to add to the factory ecu duty cycle to compensate for the fuel change.
I just did an ebay search for "EV1 E85"
http://cgi.ebay.com/ebaymotors/E85-C...item25652f4517
2 required for a v8 at $110 each

I can't see anything good coming from a visit to the smog referee. Some know smog issues really well, but can be capricious in accepting or failing a car.
Tipping on a smog test isn't something I've ever seen. I've heard of outright bribes, but not tip sized ones.

So it does work, but I screwed around with the FP too much I guess.
