Having craptastic cold starts switching to Tephra V7 from 96940011? Try this...

[Fast_Freddie]

*Percent Low Temp Timing Trim vs Coolant Temp- all columns set to 0%
*Ignition Unknown Map (Warm-up?) (AKA the Hole of 5's)- set to match high octane timing map
*Startup IPW Latency msec- Matched the 14v Injector latency value
*Open Loop Load #1 & #2- set to match the 96940011 rom
*Open Loop Throttle #1 & #2- Set to match the 96940011 rom
*EGR System Enable/Disable- set to 0 (not FAA Bit 11, but MrFreds EGR Disable routine)
*F9A Bit 2 set to 1 (the rest are zeros)
*FAA Bit 1,3,4,6,7,9,12,14 set to 1 (the rest are zeros)
*FBA Bit 3 set to 1 (the rest are zeros)
*FCA Bit 0,1,2,3,4,6,7,8,11 set to 1 (the rest are zeros)
*FDA Bit 4,7,9,14 set to 1 (the rest set to zero)
*FEA all bits set to zero

***Notes***
*Before doing anything, you need to adjust the BISS as the base idle settings are different in the V7. To do this leave the stock idle table alone, enable the SASS actuator in Evoscan and set base idle at 850 RPM.
*FAA Bit 9 (Enable Warmup Ign Retard) in my experience changing this will change your fuel trims by approx. 8% when set to zero as seen on my car...
*Percent Low Temp Timing Trim vs Coolant Temp- When this was at the stock setting my car would jump up the idle to about 3000 RPM, therefore I zero'd the columns out and now it starts up jumps to about 1500 RPM and slowly steps down to target idle.
*Open loop load and throttle. I matched these to the 96940011 rom because these are the open loop switchover points and I didn't wanna retune my map as much.
*If you happen to get a P0505 OBDII code, you need to readjust your BISS screw.

These settings are only for transitioning from the 05 VIII (96940011) rom to Tephra V7 the 94170015 rom seems to need other changes in order to work more fluidly... I will not post that information as it is not mine...

These are my settings v7....and should work well for 9417xxxx, 03 and 04 VIIIs

THE SOLUTION

EGR System Enable/Disable....changed from 1 to 0

Periphery F9A bit 2 set to =1
(Rest are all 0)

Periphery FAA bit 1 , 3 , 4 , 6 , 7 , 9 , 12 , 14 set to = 1
(Rest are all 0)

Periphery FBA bit 3 set to = 1
Periphery FBA bit 0 (Lean Spool) set to = 1
(Rest are all 0)

Periphery FCA bit 0 , 1 , 2 , 3 , 6 , 7 , 8 , 11 set to = 1
(Rest are all 0)

Periphery FDA bit 4 , 7, 9, 14 set to = 1
(Rest are all =0)

Periphery FEA all = 0


These tables must match 9417xxxx

Post Primer tables set to match 9417xxxx

Decel Fuel Cut tables set to match 9417xxxx


Additions to help startup and idle

Start IPW = value in the 14.06 latency

Idle Stability Timing Control sensitivity = 146

ALSO....

This table....for v7 96500006 versions...

<table name="Ignition Unknown Map (warm-up?)" category="Timing" address="61c9" type="3D" swapxy="true" scaling="Timing">
<table name="Load" address="6910" type="X Axis" elements="19" scaling="Load"/>
<table name ="RPM" address="68de" type="Y Axis" elements="20" scaling="RPM"/>
</table>

This will show up as a timing table with a big hole in the cold cruise area.

All I did was change the stock +5* timing areas in the idle area to my current cam timing setting of +11*. I left the hole alone other than changing the +5s to +11. It seemed to help idle considerably....the car idles much smoother and timing does not fluctuate near as much as it used to.

Good stuff Freddie. Thanks for sharing

[Fast_Freddie]

Go ahead Freddie.....you can post our findings.

I know you adjusted a few other things Paul, so you may wanna post up the final verdict...

[Appauldd]

Actually the jury is still out on those additional "things". I made some changes and the car did not respond well. I am getting a terrible engine rev and some throttle hang. I put my values back but have not been able to get it flashed into the car. It seems that I was too aggressive in idle area timing and it was causing issues. That compounded with fooling around with new table findings my cold start went to poo. I have since pulled the throttle body and cleaned the heck out of it. My BISS was all but nearly clogged with crud. Now that it is all clean I've had to give the car a few days to re-learn how to idle (LTFTs were hosed).

Lesson learned......Don't make too many changes or you may have to take a couple steps back.

I will post the results when I am done.

As for the primary findings on EvoM....those are lagit. You can copy and past then to the OP here.

I will wait for you to get completely done with your resting after cleaning the TB and see if that has fixed some of the little buggy stuff then I will post it up aight

[Appauldd]

I added my stuff to the 2nd post.

Oh and everything is back to normal.
I made one little change....I raised my idle speed to 1100 from 1020ish and lowered the timing in the 1500 rpm, 70 and below load. Very good results!

[Fast_Freddie]

Thanks for the addition Paul
