New guy have some questions about all this.

[CK_32]

Ok so I’m having another issue. I’m trying to flash that BIN file with VATs deleted and LS Droid tells me I have 0/3 previous flashes.

I found somewhere some guy had a similar issue and someone recommended they read and reflash the same OS onto their ECU.

Problem is when I try to do this LS droid gives me a low voltage warning saying it dropped to 12.2v….

But I’ve tried this on my Laptop power supply and a fresh truck battery and got he same issue. Even still 12.2 is above the 12v needed. Anyone know why I’m getting this error message?

Idk why this is turning out to be so difficult to accomplish. And for so many people doing LS swaps and using LS droid idk why there is so limited information aside from mechanical information.

I’m half tempted to purchase HP Tuners but just to delete and upload VATs this really seems to be overkill for the cost to value for me.

Try PCM Hammer.

Try PCM Hammer.

Sorry it took me forever to respond. The forum kept saying I needed to log in everytime I went to reply when I was already logged in.

But PCM hammer won’t launch on my PC. I even uninstalled and tried version 17 with the same issue. It crashes but stays open in a live state. But nothing works on 17 or 18.

I did get it to work on my laptop but it doesn’t have Bluetooth like my PC does. So even tho it works I have no way to send it to my OBD2 device.

There a million and one post on this forum and dozens of others that tell you flashing on the vehicle is NOT Recommended, even in stand alone systems.
A bench harness with a reliable power supply that puts out at least 1 full watt of power and 12.6 or more volts.
Flashing a PCM in the vehicle with a run of the mill car charger is also not recommended, as the power signal is not clean, and you can possibly brick your pcm.

Yes, it is a safety feature in LS Droid that you must have 3 flashes before being able to write a PCM.
Protocols and Safety functions are put in place for a reason, just like traffic lights at busy intersections. To try and prevent a oops, a accident.
LS Droid for Windows works great if you just follow the instructions in it to the letter, and not some you tuber that just barely knows what they are doing. There are some great tutorials online, and on you-tube, but there are also dozens more of crappy, poorly executed advice video's.
Voltage is not the only thing that matters, wattage is also very important. People trying to use a 12 volts 1/2 wall wart will not get the job done. And even many laptop power supplies drop off badly.
Pete and Jason have put thousands of hours into this and their stuff works. Especially for Free.
Now, the OBDLINK LX/MX/MX+ will NOT work with LS Droid for Windows
LS Droid Legacy (for Android Devices) does still work, but I can tell you the makers of OBDLink devices change their firmware so often, that is may work with this update, and not the next. I have 2 OBDXPRO devices and a OBDLink MX+ device. All 3 work correctly in their given environments.
Everytime I try to flash/write a PCM in a vehicle it goes bad. Everytime I do it with my $8.00 homemade bench harness it works perfect.

If you have not already, get on Facebook, join the REAL LS Droid page, and first read through all the stickies at the top of the page, then read a couple of weeks back post. You can post your question there and Pete, Jason, or one of the long time users will help you fix your issue.

The reason the bin shows pwm is the about 1999 to 2002 pcms have pwm for cameros and firedbirds. in 2003 pwm was not in these new pcms. so when your vats was edited it should be 01 not 02. 00 is vats enabled. 01 disabled then ff changed to fe so checksum is good. this is why you had trouble with the vats. i knew the checksum was wrong. this is why we needed to see the bin file to check. i have 2 2006 silverados i know what your dealing with. i would personally try to fit the 06 cluster into the dash or go with an app off the obd2 port to read things, my opinion.

when i mean edited, i mean using a hex editor like neo. if you know where to look you can alter numbers and letters to change the coding. by the way if you use the new efi live download you will see checksum fail while reading bin files. older hp tuners 2.24 did read bin files, but the vats with pwm is not in the 2003 to 2007 so hp tuner reads pwm when it is not. newer hp tuners does not read bin files. efi live will show a ? when vats is altered but the checksum is bad.

HP Tuners does not read the VATS wrong on P59s. Someone had changed his setting from the stock Serial setting to PWM. I changed to None correctly and there is no checksum error in the corrected bin I posted.

I’m aware it’s a safety feature. Just frustrating everything I try ends with a dead end for me. And I’m only using my bench harness. I wouldn’t ever flash in vehicle unless I had to for the same reason you state.

I’ll look at the Facebook group if I can remember my password. I’m sure there is more info out there but Google isn’t what it use to be. And sometimes is impossible at finding some info if it’s not on a major search traffic site or look for trending results.

try right clicking and run as administrator on pcm hammer. also pcm hammer 19 is out. here is your bin corrected with checksum fixed.

So is this different than the vat delete that 2xls posted?

Cause I uploaded his bin onto my ECU and have the same issue. So it’s still something else. I have a feeling it’s still killing fuel. I’ll try and upload a video of it from last night with the VATS bin from 2x

Clip of the crank no start. If I just hold the starter even after it fires to keep it going it just dry cranks after the initial furring.

Here are some screen shots using both HP Tuners and Tunercat OBD2 of the three different bins in this thread. I'll let you decide what is correct. First your original bin you posted.

Here is my No VATS bin.

Put a MAF sensor on it and I bet it starts. The PCM is not set up for speed density operation without a MAF. Really looking at what you have there you are in no way ready to try and start it.

any updates on project?
