I have been trying to find a guide or list of what everything means on the SCT Live Link software. Does anyone know of something like this? I already looked all over the SCT site and could not find ****.

I have no idea if this will help you and you may have already seen it but it's a PDF of the user manuel (but if you have the tuner I assume you have this)


Edit: I just read through some of that and it was not helpful..... sorry

 

You mean all of the abbreviations?

 

sort of terms you should know near as I can tell... what specific abbrev's r u strggln w/

 

I am talking about the LiveLink software that you use with any sct flasher so you can read variables on the vehicle when its running.

I know what many of them are, but some of them I have no idea what they stand for or what there readings mean.

 

it means

 

well.. ask and I will help you out. If you're talking about stft and ltft those are short term and long term fuel trims, which give an idea of how the ECU is handling the fueling duties. I'd recommend reading the SCT Advantage users guide as that has most of the detail defined.

 

I know what those means, there are just many little things I want to understand better. Like how in the hell would I known to divide my maf by 205 to get the correct readings lol.

I just have the software no manuals or anything. Got a link on this or is it hidden on the SCT site for me to find?

 

if you download advantage 3 then you should have the manual as part of it. If not, I'll have to dig mine up.

With MAF readings and O2 sensor readings the multiplier/divisor numbers are normalizing factors and this goes back to my first post... you need to spend some serious time learning about Ford ECU's to make much of this understandable. Alternately phrased, you wouldn't know to divide by 205 because SCT doesn't figure you'll know what it means anyway unless you're using the Advantage software as well (which does the actual tune programming) and using Live Link to datalog for tuning purposes. In which case, you'd have the Advantage 3 manual which tells you all about that crap.

Now then some minor explanation of the why with normalizer factors: If your maf is reading say 1 volt, then the ECU reads that as a certain number of "counts" after some minor interpretation: The ECU will take the voltage reading and use a mathematical formula to determine the number of counts. Each "count" is actually representative of a certain mass of air (by weight no less... ever try to weigh air).

The O2's are the same way... the ECU reads Lambda which is a fancy way of saying an un-normalized O2 sensor output from the sensor, applies a formula and ends up with the real A:F ratio.

I'd try calling SCT and getting the manual for Advantage which will teach you most of what you need to know. After that... well it's still sorta a guessing game in some cases.

 

I'm so glad that there are actually people who understand this stuff.....

Mechanics are all my way, but get into ECU crap and I'm taking a break.

 

There is a forum over at SCT, you won't have access to the PRP section but most of the rest of it is quite handy. Don't expect too much from the folks over there. They're not very helpful. Searching and browsing are the most helpful. IIRC Richard Holdener did a series of articles about Ford EEC IV tuning for MMFF.

 

I heard they have a forum but I cant find it. Whats the link for that red? thanks.
