Vortec only logging at 2 frames/sec w/ laptop hooked up. Also dash 3-4 mph off log ?

[Bondo Special]

2 newbie questions. I am logging a 1999 old body style classic Chevy C1500, 5.7 vortec, with a Flashscan V2.

1. Using the laptop to log through the V2 using the 7.5 scanning software, I am only getting 2 frames/sec logging in my saved data log. This is slower than the 10 frames/sec my old TPI-era obd1 stuff logs at....why is it so slow? I hope I can log at least 10 frames/sec, 2 is useless. Is there a max # of PIDs I can select to log at a decent speed, and if so, how many?

2. My dash speedo reads 3-4 mph faster than the datalog...I corrected the tune for tire size and the ecm logged speed is accurate but the dash reads 3-4 mph fast. Any idea other than my dash is defective?

Thanks!!! I am pretty computer literate but tuning and logging is always a steep learning curve for me.

What V7/V8 build versions, and what V2 firmware...?

[Bondo Special]

V2 Firmware 2.07.27 Date Apr. 20, 2012

V8 won't show me its build info under "help", says not available yet

I just bought this stuff about a month ago

Hi Bondo,

Ok, do this:
- download/install both V7 and V8 from here (you want the "full install" files: http://forum.efilive.com/showthread.php?19637-EFILive-V8-2-1-202-and-V7-5-7-211-June-22-Update-is-Available
- flash firmware 2.07.35 into your V2;
- program your BBx config to your V2 ("Program All").

After that, try logging again and let me know if it shows the same slowness or if it fixed up.

Check out the data logging speed section in the Scan Tool manual in page 186. You can get to the Scan Tool manual using the Scan Tool Help->Help menu.

As for the speedo discrepancy, I'm sorry I don't have an answer for that. That discrepancy may be built into the gauge or the cluster.
