Hi Statesman
My engine is out at the moment, keen to continue where we left off once fitted.
Likely new year.

Intake Phaser Bank 1 (INPHAB1)
Variable Valve Timing Spark (VVTSPK_DMA)
** I just wrote a detailed piece about OS compatibility, easy VVT tuning of the GenIV inspired by GenV and use of the...
I have a native non-VVT E38 successfully actuate VVT so can
Please help, I need the cam phaser to be at a set position per the phaser table at idle.
Problem is the OS overrides the table (when idle conditions are met) and parks the cam.
How can I prevent...
Sure you can detune the engine a few ways but most traditional means detune the efficiency. With an L99 you have the flexibility to run efficiently at lower power, aided with AFM and VVT.
In order...
I am interested in GM truck LFA / LZ1 (Atkinson hybrid) Cam Phaser operational info because with these motors the phaser spring parks the cam in fully retarded position - LIVC - for stop/start and...
Yes fine on beta 330.
I was interested to compare whether there was any indication that the Driving Mode accords to presets in the tune, as many believe.
The proposition is that mode changes...
Are you able to post the .ctz read?
How can stock MAP give you 120kpa?
Interesting cam! Not the info needed to confirm my guess, sorry can't help.
Advertised IVC or IVC @ 0.006"
Mentioned that, but range is probably between 60 and 70 ABDC I reckon. I think LS3 DCR over 9.3 (without building some mechanical octane) gonna need more than 93. Entirely possible OP is way over.
74.4 cc pour volume so pistons are 5.5cc dished. Nominal CR is 12.43.
If ICL = 108 then DCR = 9.5 to 9.9
If ICL = 103 then DCR = 9.9 to 10.3
Need IVC @ 0.006" to be accurate, but at a guess DCR is...
Seems high, what is the IVC @ 0.006"
Yes no problem with 93 either just keep ethanol fraction above 30% (e30). e85 is 1/10th price of the other cocktail so yeah.
Do you have an accurate number for the Dynamic Compression? Else what's the Cam's Intake Valve Closing at 0.006"?
The simple answer is to run a fuel composition sensor and fraction of ethanol (flex...
Yeah as in prior to this, with high squish smallest chamber running 26deg spark advance @ WOT on e85, made peak power at 6300.
I concluded after scores and dozens of pulls different scenarios...
FWIW I found with updated Torque Model values it is not so much the stock commanded cam position that is SNAFU, but amount of movement in proportion to VVT spark that makes things wobbly.
Start...
Both the ECU Speedometer -> Parameters; and TCM Speedo -> Parameters.
Go to TCM OS first as above then when you select one of the fields a Speedo Calculator button appears. Use that to populate...
Ok will do, thanks.
OK when you're next in Australia I owe you, and we brew some good beers down here. All good, works brilliantly, thanks!
Yahoo, it worked! Standby to see if it bricks my ECU or I have VVT spark.
Oh righto thanks, I'll try saving then reopen...
Here is same OS two years ago, the earliest I can easily find:

I have EFi 7.5.9 build 315, I will look into getting a read compatible with old EFi.

That's the weird thing - the identifiers are exactly the same in both files, mine is Holden...
Thanks that would be too easy, it seems Copy entire segment -> Engine Operation neatly copies segment data as a batch over whereas I would like to actually swap Segment as in different ID / Checksum...
