The air pump, technically, IS pushing quite a bit of air into the exhaust - as its supposed to, at the newly installed cats. Is that what you mean?

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"

2 required for a v8 at $110 each

Thanks for the suggestion - if they are non-related to other engine parameters - that is essentially the same thing to raising the fuel pressure in SOME ways - other ways they may actually help. With that sort of cost and larger injectors, I may as well go straight to megasquirt.

I read their page. I don't see where my situation is listed - they don't just want people randomly making appointments if there is no specific referee-mandated situation like engine swap, etc.

NOT a good idea. The O2 sensor would see this extra air as a "lean" condition and fatten it up even more.
Brendan, perhaps you should go back to stock injectors if you don't already have them in. It could be that higher capacity injectors are still injecting too much fuel at low RPM's even at a minimal pulse width.

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.

Everytime a comment is made against E85, you go off the handle. WTF?

yes , I thought that the car was an airpump delete for some reason....

Right now, and even before the cats, it had an airpump. As far as I know it is pushing air. Thanks.

It passed! Done and done. I think several things were learned here, but I believe that one, unfortunately, is that the previous smog guy was.... Playing me.
I'll
Scan this test asap and you can see the CO that went to 0.0.
A small decrease in fuel pressure settings causes a cat-installed car to go from 1.6% CO to 0.0%? Not so much.
I'll try and scan it tonight.
It seems like the situation is that I could have passed with no cat if the visual was not an issue and I turned down the FP a bit more.

I called the place you suggested, but they did not recognize the name of the guy Neil. So I was in "Korea/Vietnam" town (Kearny) today and went to one of the well-rates smog places there. It was in, out, and passed in 20 minutes.

This is the newest scan, and its a pass! As you can see the previous high CO are now non-existent. I do not believe such a small change in fuel pressure could have made such a large difference and I do believe that I have been played a bit by the previous guy. I don't know why or how. It could have been me getting somewhat upset at him for his foolish rigidness for the air-box top.

With that in mind, I'd be more interested in the effects on the alloy of the block than the fuel lines necessarily. Especially since the Nikasil alloys seem to be very particular anyway. Less gas mileage and replacing fuel lines, I can get over. If my block cracks in another 30,000 miles because there's less lubrication from fuel due to the alcohol content, that's a lot more expensive.

I'm not exactly clear on what you are particularly referring to when you are talking about the cracking of a block. Are you speaking of the reduced lubricity of the fuel? There is some reduction in the "slipperiness" off the fuel in terms of sliding metals like the fuel pump internals, and this is obviously something to watch closely. The 15% actual gasoline usually takes any reduction and makes it irrelevant. At the engine side of the equation there is no such concern as the normal
Lubrication system easily takes care of this. "fuel in the oil"
Is a concern for everyone, and technically speaking, it would evaporate from the oil even easier than regular fuel because if it's evaporation pressure.
The engines actually using the fuel propey report cooler engine temps. This would obviously make the oil not sheer and break down as quickly as an engine running hotter.

Nikasil? In a 928?
What did you do - swap in a flat-6?
I seem to recall this being hashed out many times before. The 928 blocks (like their baby brother 944 blocks) are Reynolds 390 High Silicon Aluminum Alloy, also known as AluSil. There is no Nikasil in the block.
