I really sucked at physics and didn't take chemistry, but this means that double the air pressure means double the volume thus fuel can simply double if the same afr was desired?

Which is supported by the fact that as you go from 100kpa to 200kpa on a map it is more than double because of the desire to be richer at 200kpa than 100kpa.

Log all your starts. Junior could use that info to tweak your map.

I will do that. I tried a different approach this morning before leaving for work. I was way too rich but I did get a log in that I can send out.

Still running pretty darn rough for the few seconds it was running though.

What are your AFRs during warmup?

My car felt happy with AFRs between 12 and 13 during warmup. Sub 10 may be too rich.

If you don't feel comfortable or confident with the changes you need to make I'd wait for backup.

I'd rather be rich and lean out that's not to o tough. Ill drop back some fuel and see if it improves . I still plan on sending junior a log to look for suggestions anyways.

Saw the new motor for the Fozzy in action today at the auto show.

2.0, 250hp, Low mount Turbo, direct injection, and dual AVCS (from the look of it), Pretty cool looking. It was a Honeywell Turbo with a .60 AR. I couldn't see if it was a twin scroll or a T3 flange.

I couldn't tell if it was the actual drive or just for the model motor but the timing chain was interesting, and also that they used rocker arms vs buckets.

Can't get this running. I played with fuel quite a bit tonight and thought I had AFRs right at some point. Guess I will have to look at timing. Something I know nothing about.
Just want to trailer it to P & L and be done with it.

That's what your wideband is for. Add or subtract fuel as necessary.

What base map are you starting with?

Fuel I had right in the thirteens and it would run rough then die. It was a combination of the base map that was included and looking at Antons map to check out fuel.

"Subaru V10 top board plug in" is the name of the map I've been modifying.

I'm sure that you know that Anton's running ID1k injectors correct? You've compensated for the difference in your injectors as well as base fuel pressures?

Somehow summit racing is going to get me my fuel line stuff to go from my ethanol sensor to surge tank. I needed a couple 90s and about 10" of -6 line. I ordered Thursday at 6pm. I will have it by saturday with the normal shipping. Gotta love it.

I'm also going to hook up the knock block this weekend. That shouldn't be too bad. I'm currently making myself a pin out diagram so I dont have to keep coming to check computer when I am working on it. Like I said, not that bad, just have to heat the garage up and do it.

The thing I'm not that thrilled about is my ethanol sensor. I plan on pulling voltage and ground from the fuel pump, because that is relay controlled and works well. The thing I dont know what in the hell to do is wiring in the damn output. I haven't looked into it that much, but it is slightly embarrassing.

I dont know which digital input is worth sacrificing for it. Was thinking the Air Conditioning request, but that is a useful button for a switch or something in the future... but I do have the cruise switch too I guess. Looking for some input for Anton / Kelly / Dominic on this one

According to what my newly hooked up Ethanol sensor is reading, I have 2.8% ethanol in the tank right now. It has been sitting for a while, I'd estimate that this tank of gas is 2-3 weeks old. I need to get a few gallons to throw into it to see what she does then.

I'm guessing it 93 octane in the tank right now and not E85?

Correct. I just measured it with a multimeter. Not hooked into the computer yet

Does your sensor have a 0-5V out? How did you read it with a meter?

Well it spits out the signal.to go to ecu. I just put the neg on the battery terminal since it is wired directly through it. Fused of course.

In other news. I think I bought a big enough filter. Barely fit



Sorry for quality ... phone picture and upload.

aiming to get my knock block and IAT sensor wired in tonight yet, but tough to say if it will get done, I have to go over to parents to sing happy bday to my dad so depending how out of hand we get ... might not work on it tonight. MAF wires are the ones dangling there, I haven't snipped them off yet. Starting to come together!

Kelly - Do you have any idea about the Ethanol sensor question i asked?

You're not using the cruise switches anyway unless you're using them for map switching.

Okay thanks - I will be using a flex map so to speak so I won't need any map switching I hope.

The real concern I had was about which auxiliary output to hook it to for 5v. Like I posted above I don't know what 5v auxiliary outputs can be sacrificed. Is a GP output configurable to be 5V all the time?

Its not a 5V output, there is a 5V bus used to power sensors and such. I have +5V, +8V, and +12V pins on my ECU but mine is the universal one.

Any 5V switched source would work if you can find one.
