And why was injector flow rate fiddled with (and none of the other injector stuff was touched) - was it like that when you got it?

How does it behave when the Trans Airflow Ramp In table (13642) isn't cut to less than half what it is in a stock file? Don't bigger numbers add more airflow on a transition?

They are also different operating systems (revisions): 68322442AA vs. 68322442AE

Axis labels are different.

No the Boost table is always always always going to be displayed as Percent (%), you cannot change it to match the weird setting you have for the Primary table. Right click, Units. It is grayed out...

Your tables, with both shown in Percent (%). In your editor, you somehow changed the units on the Primary table. Change it back.

Then multiply the whole Boost table by 100.

Yep, different units. The 105 kPa column in your boost table has 100 times less fuel than the 105 kPa column in the primary.

Maybe the Primary table got the units changed to Number () before the Boost table was done... except the Boost table doesn't allow changing units to match, it's always in Percent (%).

When it's cranking and not starting, what happens if you keep cranking and crack the throttle open?

(this is DBC, yeah? so why are you trying to log Accelerator Pedal Position?)

Might want to see to those codes that didn't get disabled...

Has anybody tried doing the relearn with tools other than HP Tuners?



Fuel cut-off is 4000 in P/N, so it's not going to...

You have to post the tune file. It is not optional.

No, the injector data stuff is my One Weird Trick (see username). Most of the rest I'm clueless about.

The flow rate table is the least important, any errors there as long as they're linear, can be compensated real real easy with the VE/MAF tables. The Offset is a diff'rent beast.

There is a link...

So why is the MAF table so inflated over the stock one? Engine & other parts from the same donor as shown in the tune file, 2003 Silverado 1500 LQ4 4WD?

The MAF table is all about the...

That VE table is suspect, too. The stock VE that goes from 15-105 has the same number of cells as the new one that goes 30-210. If you correctly transfer a stock VE over to the new one, you get only...

Correct, the 0 kPa VAC column from your datasheet all the way across, which is because the rail pressure is always 58 PSI higher than whatever is in the manifold, thanks to the little reference hose...

Injector data wrong - flow rate is for a referenced regulator, offset vs volts vs vac is for returnless/non-referenced.

The Camshaft Position (CMP) sensor is mounted through the top of the engine block at the rear of the valley cover. The CMP sensor works in conjunction with a 1X reluctor wheel on the camshaft. The...

Gen 3 engines have a 24x crank reluctor wheel, Gen 4 ECM can only use a 58x reluctor.
