Re: EEC-IV AFR at open loop

The eec will calculate how much fuel is needed based on the current air going in (MAF or VE table) and what the desired AFR is (open loop table). It will be accurate only once the fuel is dialed in.

Re: EECIV and F3 evaluate tune on chip

Since you already have a Burn 2 and adapter to read the F3, there is nothing to gain getting a jaybird. Get the QH so you can start logging.

Re: hot restart

There could be other reasons too. Did it happen right after installing the quarterhorse? Could be other fueling problems, spark, etc.

Does it start if after you first try, and then push pedal to the floor (clears flood condition)?

Re: My ramblings about LED headlight conversions

Notice in the side-by-side of the LED and Halogen. Even the Halogen has some scatter directly above the center. It does, but with much less intensity. Notice the small hot spot right above the very intense center. Then compare how wide and bright that spot is with the LED. You need that spot pointi...

You have a lot of light bleeding above the horizontal cut off. Any light of intensity should be readjusted below the center line of the headlights or you will be irritating on coming drivers if you live in a fairly populated area. Even that scattered light up higher doesn't look like 'much'. But it ...

The curve is a function of how much air the sensor read vs the actual air. A larger tube makes it 'read' less for a give flow. You could try the opposite. If you reduce the sensor's opening to read less air, you're get the same thing...

If your datalog payload has TAR (throttle angle rate), you can log that if not already and you'll see what parts of the table to concentrate on.

Re: Back to basics (for me!). So once Lambse matches the WB..... Then.....?

Yeah, once you got LAMBSEs matching WB, then your fuel dialing is done and you move to tuning. Assuming your WOT LAMBSE also match the WB, then you'd go into the Base OL Fuel table. In there is where you set your desired AFR when you go into open loop which includes WOT.

The PW goes to near nothing as the MAF dropped to near nothing. But also, 3 samples (.2sec) later it looks like your took you're foot off of it as the TP dropped. And depending how the data captured, it's possible it all happened at the same time. So what if you log again, but keep your foot into it...

Re: kg/hr for healthy 5.0

Ditto. IMHO, since you took 10% off the curve, the curve was probably good as it was. I'd put it back to original and take 10% fuel out of it (make high slope 10% larger and see where it gets you. Maybe low slope too as with large injectors, a good portion of the pulse may come from it's contribution.

Good point. Fuel, cid and a some others should be scaled the same amount if that is what he meant. Which is probably why it doesn't match the stock curves. Though seems hardly required for a lightning maf as it fits into the eec's max range. "I wonder if the low pulse width along with different vacu...

Re: kg/hr for healthy 5.0

Like Lead says, it's not the efficiency. What is happening, even though the MAFV's are the same at different rpm's, the result is that the injector pulsewidth HAVE to be different. Think about it, same MAF means same amount of air. If you have the same amount of air, what else do you need? Same amou...

Sounds like a ok number if you didn't butcher the curve too much. It is a meter after all.

Should only need tweeking if your airpath makes it misread. Looks li...

Cool. Though 1.5 would also be too high with 83's if trying to get into closed loop. Probably wouldn't be able to switch lean.

Re: Calibrated maf sensor to 42 injectors

Most simplest explanation is the MAF has it's output voltage 'scaled' by the same proportion as the new injectors are to the old ones. To scale correctly, is done by application as it needs to know what the original MAF was and original injectors were. Then you can drop both in and get by without a ...

No pain at all. It's the whole reason for this forum. To ask and learn. The beginning goal is to figure what those voltages are for the maf. The curves get you close.
