Here you go - this is from the routine that feeds internal controller data to the serial port for logging. If memory serves, the 'engineering units' was chosen for the controller's internal use to...

Not trying to refute this as it's been a couple seasons since I looked at it, but my recollection of how the PCM handles temperatures is that it uses a proprietary unit that allows the module to deal...

It's just a hobby, don't let missed opportunities trouble you.

After additional thought I wonder if you might have inadvertently "glitched" the ccm's boot process while connecting the charged...

This one is really baffling. When I get done with my current basement junk purge I'll pull the test setup down and see if I can reproduce (though I lack an instrument panel).

If I can and it does...

Ah, that's so much better.

Now I can hang it up on the wall and reclaim my workbench when needed.

Sorry been busy with other projects - first was replacing laptop keyboard so I have a ctrl key again. :-)

Finally had a chance over the weekend to wire up my aldl logger to the test bench setup...

Haven't been getting email notifications again - and I'm completely lost here is C41 / C81 a dtc or ???

Anyway, I finally had some time to work on modding my logger so it will write all ALDL data...

I was referring to the hard parts like blocks, heads, intakes, cams and crankshafts. You know, the other type of "magic smoke" where the fire is ignited by metal-on-metal type catastrophic friction....

If you would care to share the message differences, it's sort of the entire spirit of this and most of the other things I post here.

I've only touched one and may never again, but if I ever get...

LOL @ being classified a "corvette nerd". I still haven't had a chance to tinker with it, but I suspect some PCM responses are being dropped b/c I was seeing a lot of "resync datastream by fast...

I didn't get to a point I was satisfied with on this tonight, sorry. Gotta go pay my wife some attention or I'll be sleeping on the dog's bed tomorrow night.

Anyway, I'll have to recompile...

I'll try to sit down later tonight and get better logging / documentation. It's been a struggle to function without any ctrl keys - feels like I've had my pinky fingers cut off. Copying or pasting is...

I think if you could help us locate the location of the reman pin register that would be awesome. For the 94-96 units you determined it was at $644b bit 2. There are a few rom dumps staring around...

Exactly. Same reason why I (and others) have reported difficulties logging ALDL data with an 8051 PCM in a Y body. Impedance mismatch.

I've been working on logging some broadcast traffic after...

Correct $B69F. My second cup of coffee hadn't quite taken effect yet so typing was a struggle.

NomakeWan here's that 910 ohm resistor. My macro photography skills leave something to be desired,...

You're right - the bytes where the 94-96 option bits are happened to be FFs in the 90 so that explains it looking right in tunerpro. It looks like vats starts at $B6F9 and the option bits begin at...

I haven't looked at your 90 bin in any detail but just opened it up using the 94-96 xdf and the manual trans and LT5 bits were set. C68 was also set, but every bin we've looked at had that set. I...

I looked at those bins - what xdf did you use to make that change?

The only difference in the bin you wrote was the unlock enable bit at $B6CA, the LT5 bit was unchanged. It probably wrote that...

Whoa. Am I missing something or do you have like five or six model years worth of hardware you're working on?

I'm happy you're enthusiastic, but we might want to dial that back a bit. This is all...

Can you send me the .bin you attempted to write pls (will PM you my email). I can try writing it to the donor CCM. Also, please turn on the 'Comms' debugging and copy / paste that logging info when...

Very cool steveo - I never noticed that list was populated from code.

jeff I didn't test write the 94 yesterday before modding the code so no idea. I would guess yes.

Working on steveo's...

I sold my soul to Linus Torvalds back in 2008. He told me it was worthless and never cashed the check either. I suppose I should be offended, but it's the one thing I'll never find a reason to...

You haven't seen "messy". You simply haven't lived until you've lost $1k worth of hardware because you were working on a phase 3 project that was sitting on top of a pile of phase 1 and 2 and wires...

You're good:


Got reply to command: [DEV:f1] 05 AA

Means the CCM unlocked for mode 06. If you do nothing it will reboot if you don't upload code to RAM within a certain time window.

Edit:...

I wouldn't want to task you to screw with compiling it on either. steveos replied to an email so maybe he'll build it without the register checks, otherwise I'll work on building it on windows.
