When it goes lean, what it injector pulse width doing?

Is it reducing - indicating the ecu is trying to lean it up, or
is it same - indicating a mechanical issue in delivering fuel when hot ?

Try lifting the "DESIRED IDLE AIR RATE VS RPM - xxxxxxx" for each gear.

My car is a 92118883 if that would help.
I have 92161296 completete too from my donor PCM

What do you want the eeprom data for...

How big is the cam you are fitting?

220 @ .050?

I use the vx adx in my vy.
They vy adx gives funky knock numbers.

That'll be 2nd gear.

You should get pretty close to achieveing full power without the need for 100% throttle at lower revs though, think of how little throttle can achieve 100kPa MAP through the mid-range when tuning a MAP based v6.

1.28 is happier to conenct in my VY than 1.32/1.34 ( i haven't tried every version)

1.34 works ok if I canhenge preferences: Wait For Silence = 15mS, 1.28 is happy at 50mS

Why did you stay so small on the converter for a mainly drag car?
Was the thought of other non-drag applications a consderation?

I would have thought something more like 4k would see much more et improvement.

Looking good, I like the sepentine setup.

I wouldn't go anywhere near that lean in lean cruse.

In my stock N/A VY going much leaner than 16.6:1 results in a lean flat spot.

Basically, you can't.
Holden don't have them available, and many out there being purported as V8 items; aren't.

For professional tuning, a good set of knock phones and human response would be safer anyway.
