06-28-2013 - Tune #28_0019 thru #28_0021

My original plan was to use the MAF up till it ran out of it's design limits and then from there go to speed density using the VE tables only. However, when I found out that once the MAF fails, it does not reset when the values drop down into it's calibrated range, I had to abandon this path I was on.

** hiccup at frame #9105

{B0101} and {A0009} - adjusted from MAP E and smoothed

*Note: Got help on EFILive forum and used the B0101 table from a member. I then SEVERELY smoothed the A0009 table.

{B5935} Idle Overspeed Error
Cells 13 to 300 -2

{B5936} Idle Underspeed Error

Logged on 07-17

{B3647} - Copied from Tune #0025

{A0009} - Adjusted from MAP E, then spot smoothed rough spots

**Car didn't run right with tunes #0026 or #0027

**Idles REAL rough at 0 mph

**Check log for $0026 for a hiccup at frame #9105

**After loading this tune in initially, ALL gauges were dead and EFILive could not talk to PCM or V2. Had to turn off everything and then reload the tune. Gauges started working properly then.
