Steve, FYI, I just uploaded a tune to a B-body PCM (94 Roadmaster wagon) that I had previously uploaded a tune using EEHack 4.0 in december 2015. It took several attempts before I could read...

Good for you Steve. Life is seasons, time for a change. If you were closer, I'd buy that TA off of you! Enjoy the bike, and keep your eye out for a modded LT1 car with a crappy mail-order tune,...

Yep. Or folks with dirty MAFs, leaky intakes, busted exhaust manifold bolts, fuel pressure out of spec, dying O2s, weak ignition coils / ICMs wanting a tune anyway... I could go on.

Like the time...

Got it. I stopped using Datamaster for anything other than data acquisition a long time ago and built my own tools in Excel that have proportional shading and % difference. I even put in spots to...

Steveo, I just started using the analysis tools. LOVE them - they look very similar tools I built in Excel to do the same VE and MAF calibration adjustments.

Question - in the Cruising AFR tab,...

If anyone hasn't donated something to Steveo, now's the time. There's an ebay auction for some repair parts his car could really use.. ending in the next 18 hours. If you can throw $50, 20 or even...

That's interesting that the TCC didn't work for you Brian - I could clearly hear a solenoid clicking and unclicking when I tested that last night. What's your application? On the '95s, there's TWO...

BTW my blue screens of death in my earlier tests with 4.0 beta 3 were likely due to my serial adapter, a tripplite USA19HS. Later attempts resulted in immediate BSOD so I repaired the driver...

Will do. The gear indicators seemed to work correctly, at least I didn't notice anything out of whack, and I would have noticed that stuff pretty quickly given how familiar I am with the 4L60E.
...

I ran the 4.0 Beta 8 installer, then asked it to run eehack.exe. It says
"Unable to execute file: C:\Program Files(x86)\EEHack\eehack.exe

CreateProcess failed; code 740.
The requested...

Steve just a thought, I wouldn't spend any time optimizing that interface for tablets, etc. Your gifting and interest is in the LT1 interface. The trick is to find someone who's interested in...

Steve, Beta6 isn't running either. I used the installed and put it in C:\Program Files(x86)\eehack just as it asked, then copy/pasted all of the additional files over from the other folder where I...

Oh no, it COULDN'T be windows 10.... :P

Lost connection was while driving on the highway on a 30 minute trip. Someone else was driving, I was in the passenger seat monitoring connection. All of a sudden the error #s would start...

Beta5 isn't working for me either. I'm trying multiple compatibility options (run as admin, compatibility for win7), no success, and no error messages.

The other complicating factor is that...

some reports today, using Beta3 (apologies):
1. When I'd lose connection to the PCM, it would never successfully reconnect. If I hit "disconnect" and then "connect," it came back up almost...

I tried downloading it again. Beta4 still won't work. Even updated the libraries just in case.

Beta4 is not opening for me. Beta3 opens just fine.

On the FLASH menu, there's a checkbox that says "Insert Patches." Where are those patches selectable at? Is there any way to display selected patches on the FLASH screen?

I threw a tooltips issue on Github... did it take?

Additional:
1. on 4.0 Beta1, if I hit ESC instead of the EXIT button after a write, the MAIN screen seemed to get stuck on "disconnecting".
...

Yes, but it will be a week before I get another opportunity on an LT1.

BTW is there documentation of what the individual cylinder balance test results are useful for? I got a significantly...

18-1 should be 1-18. I uploaded the tune and started the car and cell 2 was the only cell not 128...

On the extended tab, I think the BLM cell labels in the middle are reversed.

Just did two successful flashes to two different PCMs using eehack 4.0 Beta1 on a Dell Laptop running Windows 10 through an Arduino board and a standalone harness that looks very similar to yours. ...

Guys,

1. I watched a GM tech use the Tech2 to force line pressure to commanded values after a new 4L60E was installed to verify that line pressure was what it should be. Is there any way to add...
