Well, not sure how it happened, but I was comparing the stock bin to my tuned bin by hand, and came across some dynamic airflow parameters that were mysteriously changed. EFI Live and TunerPro comparisons returned no differences with their automated 'Show Difference' tools in these portions, so I we...

Yeah, no wideband unfortunately.

What boggles my mind is it's only spitting and sputtering in blended mode. SD only no issues, MAF only no issues.

It's really running phenomenally in SD or MAF only modes.

I've been reading up on a ton of different guides and approaches to tuning the LS1 GenIII PCMs depending on tools, software, and hardware available. I've settled on using LTFT/STFT and driving a ton. PCM is running OS 12212156, started with a stock file from a 2002 M6 LS1 car. The only fueling modif...

It looks like someone sent us a pull request for this change. Thanks if that was you. Yep, that was me. Trying to give back what little I can. This tool has been pretty amazing and useful for me. Hated the idea of having to haul my car to someone to fix some of the issues I was having. As Antus has...

Here's the before/after logs I promised. The failure is with the old 'AT ST XX' command setting the timeout, and the Success uses the STN 'STPTO' timeout commands with a value of 7000 milliseconds. I didn't go back and set things to 3000 and rebuild for this test. But, I do see that the erase block ...

Haha, no worries! I really appreciate the help and guidance. I was on a mission to not end up with a paper weight for a PCM at the end of the day and have been bit WAY too many times by not reading the f****** manual. Seems like a decent change to make if the Apps only support STN ELM327 devices, (I...

Yeah, I'm with you on setting it to worst case. The system responds as quick as it can, so in theory it will only allow more devices to work, and the existing devices will be as fast as they've always been. AT ST is "deprecated" in STN's documentation: Table 5 on Page 8 for their chips. As...

:x I forgot I was running a differently configured PCMHammer, so it didn't save the log files on close. You'll have to trust me that it worked successfully, and flashed the entire PCM. The tool even reported that it didn't require any retries which I thought was surprising. Update eraseRequest.MaxTi...

I just confirmed my assumptions. I swapped the deprecated STN timeout command (AT ST) for the newer (STPTO), extended it to 3000 milliseconds for the erase, and the PCM is flashing successfully as I type this.

I'm fairly confident it erased because the first block it tried erasing had the CRC change. I'd rather not power down the PCM to prove your theory, :lol: You don't think the hand ran "Erase Sector" command succeeded? I sent the same bytes the App does to initiate a block erase, after modif...
