The charger gm uses is called the EL-49642 SPS Programming Support Tool produced by midtronics. Its a low ripple charger outputting up to 80 amps at exactly 13.5 volts. Its also common the green neon bulb that's inside the on/off rocker switch burns out but the unit works normally. Every reprogramming procedure gm has involves connecting this tool to the vehicle. It is also important to not use a wi-fi connection during programming. If the internet drops out or the router does something dumb, youll have a bricked module. Sometimes, if one goes back through the programming and selects "replace and reprogram" theres a chance to unbrick the module.
Use to be a service tech for gm. Still have access to gm service info.
This is amazing, love your stuff, bricked the ECM, owned it, uploaded it, moving on to try again.
I man who admits his own mistakes and shares with others is a person I want to learn from. Great Video thank you for sharing
WHAT THE HELL TAKE ME SO LONG TO FIND YOUR CHANNEL.....BRO YOU ARE DOING SOME AMAZING PROGRAMMING WORK AND VERY EASY TO UNDERSTAND THANKS SO MUCH.
Interesting video and glad you're not performing any update on a customer's vehicle with that tool. Any spike (battery draw that is network controlled) will never be handled by a "jump pack". A power supply (we use a 90 Amp floating version) will handle the load all day long and keep the network active providing the 120V AC supply is intact.
Interesting take on your problem though and the admission becomes the learning lesson. Good luck on future problems and programming updates.
Trial and error brother things never work out like there supposed to it’s not like you see on some of these fake channels we’re every thing is perfect and glamorous this is real issues we all face love that you keep moving forward and showing us how to fix real problems we face. ABT
Great info in your vids! Thank you! So I just had the same issue you had where I tried to replace and program and ECM from salvage using SPS and kicked out at 50% with E4491/E4423. I can recreate this consistently if the ECM I am trying to program has the same calibration version on it as I am trying to program onto it, but needing to change VIN requires this process to complete. If I use HP tuners and put a very different calibration for entirely different engine on it then SPS will go ahead and program to it with the new VIN. Still I am in search for a solution to get SPS to change VIN on an ECM with same calibration, not using HP tuners...
I have a brand new ecm and tried bench programming it and same here. Its gets half way and stops. Same errors as yours. E4491 and E4423.
I thought I heard something similar in some other video. I think it may not necessarily have been power related.
@@jonyovanno4145 any further discovery
I always use snap on dtac when doing Oem flashing, it has a flash mode, desired voltage can be adjusted, typically somewhere between 12.8 and 13.00v is safe. I prefer drewtech j2534 pass thru. I also have tech2, China shit scares me.
I'm still watching the video but I'm watching as my own car needs a new ECM before my mechanic can see if there's anything else wrong with it (I actually think this is the only issue with it, though). I bought a new one months ago but swapped the battery as well to a newer one just to see if that too helped. I charged it via my mom's SUV for about an hour and left it on the charging cables as I began the steps of programming the ECM to my car.
My 2004 Saturn L300 takes three ten minute cycles to program the ECM to the car. Cycles 1 and 2 were perfect, the displays came on and the gas guage moved (the gas guage has had issues where it sometimes won't move). Everything looked positive until that third cycle. On that one, a few displays came on but it was weakly lit and the gas guage never moved, nor did any of the guages. I turned the key to off and removed it, waited about ten seconds, then tried it again. This time, absolutely nada. Third time, nada.
My mom wasn't able to keep waiting around after this and I haven't solicited her help since as she can be quite busy. I tried swapping back to the old ECM out of desperation but that of course did nothing.
So, here I am today, having ordered another ECM. I can't seem to find the answer online as to if a programming attempt is only good once and then must be reprogrammed yet again or if so long it's for the same car, you can attempt it several times. I figured I'd just be on the safe side.
But! Your video here mentions GM had specific instructions on how to maintain power to the battery during this and I think my mom charging my car battery simultaneously was a no-no. Not only that, maybe it didn't have enough power after about an hour and a half anyways to finish the process. I'll have my mechanic do the process instead since they'll have more equipment on hand but it's nice to see where I may have gone wrong.
Man your awesome getting that deep into tuning. I would love to learn more, but always a little scared to mess something up. I do know enough to understand the data log and use it to possibly diagnose some issues or see if we are running good or not, but that is it.
It's harder than you think to really mess stuff up. As long as you keep a good trail to walk back on you're generally safe to play around a bit.
Goat Rope Garage Yeah, I’m sure I’ll dive deeper into it later on as I keep working on my cars
@@GoatRopeGarage does that XLR ecu have a similar plug style or pinout as an e40 ecu? I'm considering using the XLR ecu for my Gen 3 swap. I was thinking I could flash XLR as a e40 or vice versa
Man I have been having one heck of a time trying to program a 2006 Hummer H3 BCM. I've got tech line connect and a MDI clone however every time I try to program this thing it stopped mid-cycle and then retries three times with a failure code. Finally for some reason I tried it with the ignition switch off and surprisingly it took the firmware and tried to write at the end and then retried three times but now I have interior lights and everything seems to be working mostly my question is do you flash with the key off or on?
SPS will launch in Chrome. Download that file and then run it. I tried it and it works. Been battle testing this since your last video about the VCX Nano. And ummm... THANKS FOR THE INFO ABOUT THIS LITTLE TOY. Im loving it!
I'll try that, thanks James!
@@GoatRopeGarage Youre welcome bud. Im an IT Tech by profession, a former GM tech and gearhead at heart. Always willing help a follow gearhead out...
So when I try to add a new vin it wants to install a entire suite of software from ac delco. I assume there is some kind of bad authentication so internet explorer wont detect the tds software?
Hi, can I bench program a gen4 E38 ecm? I have all the needed tools (J2534, TDS license, etc) but I´ve never tried on a bech. It´s an LS swap platform (2010 Camaro SS donor) that needs an ECM replacement. I don´t have any other modules like the BCM of the donor vehicle. TIA.
Flashing these early push button Caddys (Sts Xlr) ive always have had to flash pass thru with 232 cable and tech2. Always get an SPS error code with the j2354 tool; wireless or passthru.
I'll try that next time, Andy, good suggestion!
I appreciate your content. 🤘👍
Do you have aftermarket electronics on it? I had a module program fail issue because of an aftermarket radio. I pulled the radio fuse and it worked.
Have you used the VCX Nano to reprogram a BCM for anything around year 2003? I have a 2003 Impala and I believe I have a bad BCM. The car drains the battery overnight. I bought a VCX Nano but I haven't used it yet.
A deep cycle marine battery 100 bucks keep it on the trickle charger till needed
Hi,
This is going so smooth. In my case I had the message "No vehicle authorization" after confirming VIN (video 10:27) does anybody had this issue?
Greg
Did you ever get the vcx nano to program anything succesfully? i am installing a remote start onto my 2020 silverado tommorow, and using my nano with sps to reprogram the bcm. wondering if thats going to be a good idea...
I've programmed a few things with it, but I don't know that you'll be able to do the BCM without a code from GM to enable it in the BCM and I don't think you can get it without being a service advisor
@@GoatRopeGarage is that vehicle global a? If not have you ever successfully programmed a global a with the same process?
Can't bench program global a, but I've done it in the car in global a cars
@@GoatRopeGarage but what year did you do it? Sps changes their policy and software from time to time
@@swishyyyyy last year
I had this fear while doing the MAF patch on the E40, the USB-C cable that came with my MPVI2 is super flimsy and loves to disconnect while data logging. Probably not the issue but I think some of these vehicles may even have an accessory mode time-out where it starts to cut power after a certain amount of time.
Get a remote obd port and mount it somewhere like in the center console, that's what I usually do so I don't have to worry about things like that.
GEN three, Silverado classic, unbricked my ECM, now it won’t idle. bricked my generator control module cause I get the wrong ecm from a yard. But it will run and charge, it just will not idle at a stoplight in gear. Drops to neutral to keep it from dying. any suggestions?
Man I have never bricked a computer! Tuning back in the Lt1 days always made me nervous. I just didn’t trust those pcms.
My mom has one of those xlr’s. Trying to convince her to let me pulley and tune it lol.
Good content as always my dude.
I am losing my mind with a vxdiag multi j2534. I can not get the (acdelcotds) gm sps system to recognize the vxdiag. I have all the software that came with it. The vxdiag connects in gs2 and tech2win. I did the same trick as you, with the new ebcm, tech2win thinks the wrong vehicle (2006 Buick) is in the system, and it communicates well with the tech2win. Any suggestions how to get the vxdiag to communicate with acdelcotds sps? I noticed you said it doesn’t always recognize the device, I hope you know.
I've got a question, may not be entirely related, but here goes.
I've got a 2011 Cadillac STS that doesn't have RPO code NV7 for the variable assist steering. I'd like to install the NV7 steering rack, though. I think I have to reprogram the EBCM to accept the new rack. Would reprogramming the EBCM for the new part follow a procedure similar to the one you've recorded?
Sometimes the EBCM Isnt able to be flashed on some vehicles... but make sure your car also has the steering angle position sensor on the steering column.
What is the conclusion of this video. Did you get the computer reprogramed with the vxdiag vcx nano?
I need to do something similar and this is the only video I could find with the vxdiag vcx nano.
I did. But I use a clone MDI now because the nano is a pita to setup
@@GoatRopeGarage the same ECU that would fail in this video you were able to successfully program with MDI?
Correct, I was able to reload a full stock tune from SPS and then use the ECM
@@GoatRopeGarage thanks! What do you think helped? Was it flashing it off the vehicle network or using an MDI instead?
I used a VXDiag for this, but same process, it's like the file had gotten corrupted but the write process from SPS fixed it.
used this program on a 2007 Cadillac Escalade TCM but the vehicle had on the old TCM foolish mistake it flash the old TCM with ez but when i try programing the new TCM in your video at 9;56 am getting a pop up e4399 severe error any thoughts from any one
So I get to the point where I choose the vehicle I want, and then I get an error that says E4403: severe error. reading VIN from device or controller failed. What's up with that?
Did you get the nano to program the ecm. I have a 2008 Saturn Astra ECM Saturday. The j-box I have is the nano
Not originally though I've used it a lot to do that lately
@@GoatRopeGarage anything I shoould know.. I have the immo code so I can remove the bad ecu and then install the new ecu to marry it to the cim on the vehicle. I've used my tech 2 in the past to program as a pass thru device but my tech 2 software doesn't cover the Astra because it doesn't fall under the north american operation software. Just worried about bricking a $300 ecu. I've read the TSB on this seems pretty straight forward.
Why didn't you just pull away the interior light fuse (and any other fuses which can cause the same problems)?
I got tired of just watching your vids i ordered hp tuners so i can paint along with Bob Ross.i think im going to get some more ecus now
How do u install the vxdiag correctly
It doesn’t come up on sps
With TDS+VCX Nano if you buy a 2 year/1 vehicle programming software subscription ($53) don't you still need to have a valid VSC ID and password for any ECU programming? (that costs ~$400 w/ a background check)
Nope, not even sure what you're talking about
@@GoatRopeGarage I'm glad to hear it's not necessary. VSC=Vehicle Security Credentials (you enter the ID + pass in your profile on acdelcotds.com). I was worried the Vehicle Programming Software subscription you buy on acdelcotds (1 vehicle/2 years is $53 CAD) would require you to have that in order to perform functions on the vehicle that need security access like key, ECU (& other module) programming. I think I'm just getting my wires crossed from only having used GlobalTIS. Thanks for confirming!
@@v4thjhr - I think the background stuff might be for the vehicle security people? Locksmiths that do keys and such and need to reprogram the immobilizers. But anyone can get in and do the module programming.
Now I'm scared to try re-righting my 6l80.
It wouldn't be so bad if the controller was easily swapped on those.
im sure you already had your reflash done by now, but for anyone that needs to know. ive used the nano with techline connect and flashed several of them torque converter eating 6l80e tcms with no problems whatsoever. make sure you have a good battery in the truck and laptop. ive flashed several different chevy trucks and cars this tool has been a lifesaver. i cannot figure out how to get tis2000 to work though
Funny enough, I just figured it out .just not sure I can replicate the procedure again. As I had to switch over to a i7 2nd gen laptop. My newer laptop died trying to figure this out. Do you know if this old i7 2nd gen can do the programming? As by gm standards, it’s a big no no.
Should be able to
I know I'm late to the party..but why not just piggy back another battery with lets say..jumper cables ?
No readon that wouldn't work
Disconnect the high speed lines. Basically you’d benching it.
So what can I do with that device without buying any kind of subscription from gm or ACdelco
I hate to bother you. I installed the pass thru software for the vcx diag. How do I determine the settings to use so GM Tis2web see the vcx diag as a pass thru device? I couldn't get it to work. Luckily I was able to use my Tech2 as a pass thru to get the ECM programmed.
When it launch Tis2Web it will pop up on the device selection list as the VXDIAG under the MDI options, if you don't see it in there launch the VX manager and make sure all the drivers are installed.
@@GoatRopeGarage I'll try that tomorrow. Right now it just shows GM MDI
@@GoatRopeGarage When I ran vdxi manager I didn't check pass thru just the gm mdi. Once I did that and ran it I can nos see the viaxdiag passthru.. Once I did that I ran the sps again it now see's the vixdiag and can talk to it thanks once again for your help. Now just need to figure out U2101-C CAN-Bus Maximum Configuration List Not Programmed Present
P0610 Control Module -Vehicle Options Error Present
and U0073 CAN Bus Communication. Looks like I have some research ahead of me. LOL Once again thanks for the help.
I doubt you bricked it, make sure your battery charger is 15+ continuous amps output, if not I wouldn't be programming modules in cars. or buy a used midtroncis charger 75 amps output like the PSC-700. Key on engine off programming I bet your using almost 30 amps, plus the initial key on engine start, is about 50 amps pull then drops to about 30amps of continuous amp draw. put a better charger on there and retry.
I'll try it again on my bench setup, but it's completely non-responsive now.
@@GoatRopeGarage its pretty hard to brick the these ls ECM's, yeah let me know if you get it working, I love HP tuners had it over 10 years now, and my VCXDIAG over 1 year now with SPS has been awesome.
I'll be doing a video on bench and in car programming but using something with more amperage overhead to back up the battery.
I got it to flash on the bench, which might be an indication as to some of the issues I'm facing on getting the car to start. Glad you said something!
@@GoatRopeGarage sweet!, cool stuff. I flashed a few ecu's in my day. lol. glad its working, if BCM is on the fritz, or factory radio is missing/ on the fritz, programing can fail, as well as lower voltage, if you have a mid/large amp draw while programing you eating more power and the VXDiag will disconnect.
also maybe make an update video outlining the steps you took to help others.
Just a Cadillac owner helping another caddie owner, send it!
You sure that's a V bro? I don't think so...I got an 09 V.
First 👍
My 2004 Cadillac ctsv requires me to pull the radio fuse to read or write. P59
Interesting! I wonder why that is? Which radio is in it?
@@GoatRopeGarage stock radio by my 04 ctsv has alot going on with radio with info etc. I was mid read and about had a heart attack luckily I got lucky by switching out of high speed and was able to finish after a 20 min read. Then after contacting hptunner and ctsv forms found that radio fuse is the problem causing noise. Pulled that and now I can read/write in high speed.
Was it bricked or is that you don’t have the proper battery charger ?
Neither, had issue with the can bus. Built a bench harness and saved it.
Goat Rope Garage so you were able to program the ecm with the vx diag ?
Why you can't change the vin using hp tuners? I didn't get it why are you programming it in the first place?☺
The OS determines what features are actually used on the ECM, I need to be able to control 4 cams
@@GoatRopeGarage ohhh i get it but is it possible to download an os from hp tuners repository that is a four cam based and strat tuning from there?
@@ehworkshop9922 No, they only contain certain sections of the ECU's information, which is why we have to get the whole image loaded first. I'm not sure but EFI Live might download the whole image.
@@GoatRopeGarage EFI Live Should do a full rewrite, Find the right file and ill flash it for ya, I dont have anything for that particular model
Build a lithium battery bank, it'll keep steady power on the system for days
