You changed the TCM (transmission) which does not have its serial number tied to the license. If you change the ECM (for the engine) it will prompt you for credits. Your license is a combo of the ECM...

Swapping out only the TCM and writing a file you've already licensed doesn't need more credits. Can't do that with the ECM though, that breaks the license.

Apparently, according to what HPT has...

Now reduced to $2000. Anybody have a car hauler for sale cheap?

Am I the only one attracted to old rusty junk? Apparently.

Is Holley's filter/regulator like most of their products, where they simply take a Chinese copy of a commodity item like a stock replacement filter for a 99-03 Corvette and put it in a Holley box and...

Nope! You just need to add a few decimal places...

Think maybe you should clean up your DTC list for stuff that isn't being used anymore?

This all seems very random poking at things, I think some studying and finding a methodical approach to...

Add the filter string: [50118.239]=1&[50091.156]>0

That is a quick'n'dirty way to exclude everything where EQ isn't 1 and APP is at idle.

Raise & hold RPM, for what? Are you just tuning idle? If so you need the idle tuning guide.

Uh, how is it going to be rich if it's in closed loop which corrects it back to stoich automagically?

There's a pre-made math thingie for STFT+LTFT in the scanner. Just make a graph that uses the same axes as your VE/VVE table.

Why do any of that? Why try convert a trans specifically made (and priced, I'm assuming) to be a stand-alone thing for high-dollar hot rods into a non-stand-alone? Sell it to some rich guy and buy a...

Do not read anything from the vehicle after the new trans is in. You don't want anything that's already in the new TCM. You want to put your old file (just the TCM) into the new one. When you go to...

Referenced reg also helps keep things more predictable, or a better chance of making up for any errors with other parts of the tune, since all the columns are the same no matter the rail/manifold...

If there is only a single feed line going to the rail then it's 'returnless'. If there is a feed line and a regulator on the rail with a little vacuum hose going to it and a return hose from the rail...

Gen 3 truck intake, or Gen 4? Long, medium, or short injector?

Are you looking for a specific part number recommendation or just general sizing info? Because sizing you can get with a webpage and...

Pushrod length?

Does it maintain fuel pressure in the rail after it's shut off? (if it doesn't, look for a leaky injector, which could cause hydro-locking with fuel, and of course rich condition,...

...and has enough alternator output, and enough cooling, and enough A/C, and enough oil flow, and...

It'll actually be using fuel trims for your tuning, not the direct O2 voltage. LT/ST trims are how the ECM controls rich/lean when it's in closed loop. Positive numbers are adding fuel, negative...

You have it switching to 'MAF-only' above 2,000 RPM.

HOW TO FAIL MAF:
Dynamic disable/reenable: 8,000/7,950
MAF fail high/low: 2/1 or 0/0
DTC P0101/P0102/P0103: MIL on First Error

You need to check the pressure at the rail, because you are DIYing electronic fuel injection. You have changed a whole bunch of stuff and need to: 1, verify that it's working like it should, and 2,...

No liquid filled. No permanently mounted on the rail. Needs to have a hose long enough you can put it somewhere you can see it from the driver's seat. It's supposed to be a diagnostic tool, not...

That does not make it a 'return style' system - Corvette filter/regulator functions exactly the same as if the regulator was built into the sending unit inside the tank on a returnless system.

'TBSS intake' is as bad as 'my Denali'.
