Hmmm... Interesting. So that will change the values in the main fueling?

Doesn't that affect the cold start stuff too??

In your experience how is that quick tune thing where you hit the actual AFR vs the target and it just updates your fuel cell?

The quick-tune looks pretty cool.
I have seen some videos on YouTube demonstrating it, and it seems to work pretty well.

The nice thing is the software is doing it, not the firmware. So if you try it, and don't like the results, you don't have to save it.

(I'd make a copy of your map first anyway)


From what I've seen, you turn it on, and then spend like 3-5 seconds in each load site on the map.
it then changes the fuel value to match target AFR.

It's way easier on a load control dyno when you can just lock it to a fixed rpm and just vary load with the gas pedal. I had to tweak the tolerances a bit to use it effectively while free reving.

I have seen those videos before, what I was talking about is quick trim. I called it the wrong thing.



I was wondering what people thought of this. I would imagine it would be dependant on how accurate your Wideband was.
I can see from that little demonstration how crucial it is to be right though. from 14.5 to 14.7 afr was .3% of fuel. It wouldn't take much to be off by a mile.

I played with that a bit. You're using that to tune fuel from your data logs. Used mostly for the high boost areas of the fuel map when you don't want to hold 7000 rpm and 30 psi while you wait for quick tune to tune the cell. I don't see any use for it in the areas of the map where it's safe to quick tune or tune manually.

Oh 10-4 makes sense.

I want to swap out the Bosch sensor if my gauge and the link don't match any more.

Either there is some serious lag time or my sensor **** out on me

it will auto add / remove based on AFR target map, works pretty damn accurate !

that's pretty cool.

What is your guys' experience with Bosch sensors (AEM wideband) and going bad?
What my in car gauge and my computer says are different, by like .8 afr. Computer always says leaner. Kelly suggested to look at the grounding, it is grounded to all the other gauges and then to the chassis together ... "daisy chained" if you will


Finally - I had it idling at 1100 and it runs fine, but when I let off the throttle it just putters out. I have idle set at 1100 but it doesn't listen. Any insight?

All testing done with coolant at 95C or highee

Daisy chained grounds are a no no. Ground all common devices at a single point. If you want your gauge to read as close as possible to the ecu you should ground both at the same point or close to it.

For idle I'm assuming your open loop idle control, if so the idle rpm table does nothing for you. You need to adjust the idle base position table as necessary.

Use the config tab more. It has pop up help on anything you click on.

10-4. That makes sense. Never really considered that before, my logic at the time was that grounding to the battery would be the best place to do it.

I have a wire that was going over that direction anyways from my serial line so it will be a 5 min swap to solder that one over and ground to the place the ecu is grounded to.

When the car first starts up and the sensor is warming up, the sensor and computer match. After a while is when the variation starts. Ill do some more.checking tomorrow.

I will also do some checking on the open loop vs closed... I was looking at that base position table and it said that it was for a stepper motor setup only; which I am.not using so I didn't consider messing with it

Lastly -

I was trying to data log some.of this stuff and it says that my MAP sensor has NO DATA, along with a few other sensors. Do I have to use a different pin or something? I'm getting fed up with being ignorant ... I don't like being in the dark like I am now. Gah.

ECU logging or PC logging?

If you use ecu logging it automatically logs every parameter. With PC logging you have to define what you want to log. If you don't have data for a parameter it's because you didn't add it to the list.

Okay thanks. You're up early! Part of the 12 hour maintenance shift?

I thought I set it up but must not have done it right.

Thanks, it is going.to be a mission today.

Yup, shutdown is ramping up and I'm gonna miss the Superbowl because of it. Doubletime makes it slightly more bearable.

Yeah big money from 7-12s. I had a job this spring where we worked 7-12s for 44 days. On average the guys made 1.43 times their normal.pay rate lol

Bored.

Tested to see if the knock block works or if I just had a Ricer LED in my dash. Thankfully it worked. I forgot my laptop at work otherwise I would have played with the gain on it to figure out what is best setting. Anton - if you're reading this, did the setting you used for gain work okay? Cause I haven't played with that at all, Just changed the frequency for the stock knock sensor

I might earn myself some Volk money if the OT is right. Tax returns, crazy OT, and my profit sharing will all be paying out in the next month or two so at a minimum I'm gonna get Dom to finish my 2.34L long rod motor for me then plan on getting that in the car.
