I recently switched to EVOScan from Mitsulogger for the 3 bar map logging but, I'm trying to get EVOScan to log my LC-1.

For some reason the wideband request channel is only showing figures between 3.xxx to 5.xxx? It almost seems like it is reading in volts? I was able to confirm correct function via Logworks so I'm pretty certain its EVOScan.

I had doubled checked the fuel type as gasoline and even recalibrated it but, got nothing?

Suggestions?

 

you sure you have the correct com port selected? my lc-1 worked right off the bat with evoscan 2.5

ill check my evoscan next time i get a chance

 

Yeah, correct com port. I know it's communicating because I'm getting readings but there 5.xxx and below? I logged the LC-1 using Mitsulogger no problem.

All that needs to be done in EVOScan is to check the wideband request box, select the wideband and choose the com port than it should work, right? I also checked the AFR ratio box as well but, it has no effect either way. It just sits at 14.7?

Very frustrating.

 

In EvoScan the WB will only work when you are on the gas. So what Im saying is, if you do a test log with the car at idle it will stay at 14.7. Even if you rev a little it will still say 14.7. I think there is some kind of load threshold in Evo scan. This is how mine works. Hook it up and go do a pull.

 

Here is one of my Idle logs. It just sits at 14.7 even though I can see the AFRs going up and down on the guage.

 

AFRMAP is NOT the Wideband...

Look for column WideBandAF

 

Jesus, I have been tunning with that column. I was wondering why my AFRs were diffrent from the guage. Anyway I dont see the check box for the WB in Evo Scan. I got the right com port ect.

 

external wideband a/f ratio. That is the display name

 

This thread may have saved my motor...Thanks . Time to retune the whole darn car

 

Now Im having problems getting the WB to log. I have EvoScan 2.5.

From what I understand you need the KeySpan USB/Serial converter for the best results, and thats what Im using.

 

Damn, after reading what Turbo Kyle wrote earlier it looked like he had cleared my problem up but, now it seems we are both having the same problem.

The issue is this, the external wideband a/f ratio fluctuates anywhere from 5.xxx through 3.xxx??? I'm not using the KeySpan converter, I'm using a iConcepts but, it works with all my other loggers fine.

Is this the same issue your having Kyle?

 

My WB cell is dead in EvoScan. I dont know whats going on. However, I did add about 15% of fuel to my map to make sure its safe. I need to get this freakin WB working...I think its time to use the SEARCH button, LOL

 

Install Logworks on your machine, open up LM programmer and reset the LC1 calibration to Gas (14.7:1).
If you disconnect the serial/com connection to the PC while the LC1 is still powered up, it sometimes resets the calibration to custom.
This is what is giving you low numbers.

 

My LC1 feaks out when I plug/unplug the serial port when its powered up. It seems to work fine after I turn off the car and start it back up.

 

Never, Never pull the serial plug out of the LC1 when its powered up. It will loose calibration since you're shorting out the the connection when the plug is pulled out.

My LC1 works fine with evoscan 2.5, make sure that LC-1 (Direct Innovate serial protocol 2) is checked too (see wideband on the top menu)
