LC1 CALCULATION

[TAQuickness]

I got my LC1 hooked up, and did my first pass at an auto tune. I don't think my numbers look right, so, I wanted to verify what the correct PID formula is for an out-of-the-box LC1.

My SAE Generic file came with:

(({EXT.AD1}-0.5)*3.3418)+7.35

I modified it and used:

(({EXT.AD1})*3.3418)+7.35

Which one is right?

[TAQuickness]

Just got a responce from Paul.

Looks like:

({EXT.AD1}*3)+7.35

is the right formula.

Are you sure formula is correct? I just hooked up my LC-1 last night. Logged data. AFR was 10.71 or something close. Just installed new AFR 205's, Comp Cam 228/232 114Lob, Long Tube Headers. Figured formula was wrong. Entered new formula as listed above, now I get error for PID "Wide Band AFR 1- LC-1" It says Expression is Not valid because of Unknown parameter EXT.AD1*3+7.35 at position 19. Any ideas?

Make sure you enclose PID names in expressions with curly braces like this: {EXT.AD1}
Otherwise EFILive won't know that it you mean it to be a PID name.

Checked and ensured I have the formula as written above. Yes, I used the wavy brackets, just could find them on key board when I was posting. I still have the same error message appear. Do I need to change both AD1 and AD2 for it work? I only have AD1 PID selected.

Attached is my sae_generic file.

I don't think his problem is with the cal, I believe it is with his LC1. We did a test and it doesn't appear to be getting any volts from a volt meter with a good ground and power. He is going to call innovate tomorrow.

I'm a little confused (black02ss) are you talking about me in your last post? I was just trying to verify the formula posted by TAQuickness is correct. I'm using the EFILive formula for the CALC.BEN_LC11. to autotune. Sounded like I needed to change my formula, I wasn't sure. My LC-1 appears to be working, my data seems correct. I've performed two basic in the garage autotunes (tests) so far. It seems to be working, but my knowledge level is low. Would another BEN instead of CALC.BEN_LC11 work better? Thank you.

Also LC-1's are a little touchy to hook up. I've posted on Innovate forum and was able to resolve "my" O2 heater calibration issue. Basically the grounds must be hooked up just right. If anyone needs help on that, let me know I've spent many hours to getting it right.

I don't understand why you want to create a new PID when it's a lot easier to reprogram the LC-1?? Set analog out so that .5~4.5v = 10~18AFR and use the TechEdge PID already in the program. Saves the worry of whether or not you have the formula and programming right.

I'm using v7.2.3. "CALC.BEN_LC11" is a selectable PID. I'm using "CALC.BEN_LC11", "CALC.AFR_LC11", and "EXT.AD1". Are they the best choices to use with my LC-1? Why would I need to reprogram my LC-1 if EFILive is already set up for it using the listed PID's? Thats my question in relation to the orignal posting. Do I need to change the PID formula from (({EXT.AD1}-0.5)*3.3418)+7.35 to ({EXT.AD1}*3)+7.35. My auto tune seems to be working, but I'm new and easily could be viewing the data incorrectly. Thank you for your help.
