V2 AD1 voltage adjustments?

[Redline Motorsports]

I am having an issue with getting FS to read the correct output voltage from the WB. I had all this working a few weeks ago and it seems like since I have done a few updates something is screwed up. The voltage that FS is reporting is off almost 2 volts from what is being outputed by the WB.

Stumbled across the FS Control Panel with show some voltage calibrations but I am not sure if that is what's needed or not.

Trying to get a car tuned right now and this is pissing me off!

Need some ideas!

Thanks

If you are sure the voltages are being read incorrectly then the voltage calibration is what will be required...

I measured the output voltage coming out of the WB and going to AD1. Its different then what the PID for AD1 is showing.

After you calibrate the voltages for the FlashScan V2 the PID should match what is measured by volt meter.

Joe,

Do you really need an external voltage generator to calibrate this? What if you can't make your WB produce a solid 1v?? I read the link, which helped to understand what is happening.

Is this step for adjusting fine Mv differentials only? Is a 2+volt spread something else or is this the issue?

Thanks

Howard,

Yes, use the WB to output 1V... see the red parts in post #2 in the above link... showpost.php?p=43056&postcount=2

I believe the AD calibrate can handle a 2V spread.

Sanity check: make sure you're using the correct AFR calc pid.

Joe,

The oddest part of this is that I had all this worked out a few weeks back. I actual sat there with the voltmeter and observed the AFR's which I then made a spreadsheet for to double back the calc pid formula. Bottom line is not such much that the FS AFR is off (which by the way is off exactly by 10!) but the voltage being measure going into the FS is not what it is showing under the AD1 pid. This to me at this point is a issue with the way the V2 is handling it.

Just out of curiosity; where can I buy a 0-5 volt power supply that allows me to vary the voltage to any value within that range. Not a must for this by I have some other projects that it would come in handy as well as this!

Thanks Joe!

If it was working and now it doesn't, something may have broken or changed...

Radio Shack online may have something.

I am just wondering if the firmware updates and/or updates changed anything. I'll figure it out..
