PLX, V2 Voltage Offset - HELP!

[ringram]

Great, Id love to hook up direct to the LC-1..
Innvoate updated their own units recently because of similar issues with offsets and voltages blowing the unit etc.

The guys that designed FlashScan have been hard at work figuring out what can be done to limit external influences on the WB voltage as read by FlashScan.

The best solution is to use the RS232 serial link into FlashScan and get an exact digital wide band AFR value. The serial interface is being developed for the next major FlashScan firmware update. The LC1 will be the first wide band supported by FlashScan's RS232 interface.

The next best option is to return your FlashScan unit to EFILive. We can replace some of the components in FlashScan to higher specification parts. Parts with smaller errors and better resilliance against ground offset issues. These parts cost more but testing has shown that with the higher quality parts we can reduce ground voltage influences that can otherwise cause up to 50mV variance.
This upgrade is not free, but EFILive has decided to subsidise the upgrade and the final cost should be less than $20 (plus shipping).
I highly recommend getting this upgrade done. We will announce a formal upgrade procedure very soon on our web site.

Another option is to make sure all ground points are as resistance free as possible. Running a low resistance ground wire from the wide band directly to the battery negative terminal helps.

Lastly, some grounds change then the ignitions is switched on. What appears to be a goo dground with the igntion off can have a small voltage when the ignition is turned on and even more so when the engine is running and the alternator is charging. So when you are checking for ground issues, check under all three cases: Ignition off, Ignition on and Engine on.

when is this going to be available?

when is this going to be available?

The A/D hardware upgrade option is available now, we just have not updated the web yet. If you want the upgrade done immediately then send your unit back to EFILive for the hardware upgrade. Please contact us before sending your unit back for the upgrade.

We will set up a web page that explains how to send the unit back, what it costs (and payment options), what gets upgraded and how long it should take.

when is this going to be available?

The LC1 (and possibly other wide bands) serial interface option will be available as a free software update once BB logging has been released.
BB logging is scheduled to be released (possibly as a pre-release version) prior to SEMA this year. The serial interface option will be released after that, most likely before the end of the year.

oh man i can`t wait to get rid of the analog outs!
mine flutter like crazy.

We have made a firmware fix for jittery A/D inputs. The FlashScan firmware now 10x oversamples the A/D inputs and averages the input data every 100ms. That conditions the incoming data and provides a more stable A/D value to the EFILive software.

I've attached the firmware with that update here. Unzip the file into \Program Files\EFILive\V7, then run the firmware programmer to update FlashScan's firmware with the new V64 file.

That is happy news!
Thanks Blacky

Can't get the zip file to download. Can someone send me a copy?

What's wrong with the link? Not much value if you can't download
