In order to dispel all confusion....

A look up table, compliments of donour and myself...but mainly donour.

 

Holy schmoly am I running rich! Hey Dustin, where can we download comlog6 (is that correct?)

Thanks for the update, and now back to tuning........

 

i think thats the commslog they were talking about earlier. and i'd like to know where it is too..

EDIT: DONOUR do you have a beta of pyXede ready that will log AFR and Knock for us, so we can forget about this XMap high-speed logging bug

 

Check the secret web link. I just downloaded commslog from there.

 

I just downloaded commslog into my Xmap3, will the high speed data logging automatically work now or do I need to do something else?

 

Dustin, does the smart fuel table need to be recalibrated? Because between 6-8k it's shooting for 10.0 afr according to that chart. Wouldn't that be a bit low? Or should the analog output on the LC-1 be reprogrammed? Thanks.. just a little confused here...

 

I'd just run commslog6.exe, don't even open XMap. It has its own standalone interface.

 

I guess this thread to "dispel all confusion" didnt work out all that well


Rushin, the point of this table is just a reference so that when you datalog AN1 you know what that value corresponds to. Dont go messing with the smart thresholds or LC-1 calibration, you're likely to mess things up further.

 

The SMART fuel table does not need to be recalibrated. It is just fine the way it is since the "zero line" was set based upon the AFR targets displayed on my dyno's wideband (the one I use for custom tuning). The actual AFR numbers are meaningless for the most part. Just shoot for the "zero line" on the SMART fuel table and let the xede do the rest.

There's nothing magical about that table. It's just calculated from the numbers in the LC-1 manual. Where V is AN1 reading (percent of 5v):

AFR = (22.39-7.35)*V + 7.35

That's all she wrote folks. I generated the table simply by writing a program to calculate that on all the possible volt reading in AN1 (there are only 256 total). As I told dustin, you don't need a table if you can remember that ^^^ formula. The table that shiv posted a while ago was taken from the wrong place. It's perfectly correct, just not for our LC-1.

This is what I am wondering about. How do we know where this 'zero line' is, and how far away from it we are?

Do you mean that the AFR numbers in the smart fuel table are meaningless, not the ones datalogged right?

 

Yes, please explain what the "zero line" is, please remember that we are just looking at numbers, this is a language to you, one that you are now fluent in. We need a translation book!

 

I'm not sure what you mean by "actual afr numbers"

My regular fuel table is shooting for 11.1. When I enable smart fuel I can see it adding more fuel, and according to the formula or the table, its "zero line" at 6k is shooting for 10:1. Should we be running 10:1 afr in that range or is smart fuel not calibrated correctly?

 

I echo your sentiment. I see two cases.

1) The LC-1 is calibrated correctly (the way Innovate intended) and the signal represents actual AFR values. The current Xede firmware may not inpret them that way, but that's what they are.

2) The LC-1 (edit : ) signal range is a narrower band because of calibration. This doesn't matter since the Xede isn't inpreting the signal as true AFR anyway,.

Case 2 doesn't seem possible since the analog out is calibrated by innovate, not vishnu. You can see it's exact calibration in the LM Programmer. That's where you got the numbers for your formula.. right?

EDIT: oh.. do you mean that vishnu had their lc-1 recalibrated?
