Anyone know a good resource to find certain canbus ECU ID and data. I did some searching and came up empty. From searching I found CAN DBC File might be helpfull in decoding but cant find one lol....

embarrassing mistake, but I wanted to share since multiple people were willing to help

update: found the problem. It was not crank relearn procedure, youtubed it and usually you get a p0315 code....

I double checked the Ignition/Crank/Run and B+ at the fuse box, all good.
I was about to...

I made a spreadsheet 2019 and 2014, minor differences... such as hood swith signal/low ref, fuel pump prime, motor lin bus (for active flaps) but other than the fuel pressure sensor the same so I...

I've wire tested as I would do on a customers car: sensor to ECU, .2 ohm, checked shorted power and shorted to ground - all pass. pin drag test good. Well, wires are good must be sensor... just...

I am hella stumped. 'done several GenV swaps, this is first e92a ECU version though.... This swap has a 2 second long crank, sounds broken lol.. after 2nd crank or so, i get P0355 crank sensor fault....

I paid closer attention to the counter on the log file, 2 full seconds of cranking before engine rpm counts and then runs... as far as logging the cam counter counts... It was a post I found to...

thank you @GHuggins for your reply and recommendation. I will do a write entire tomorrow, I want to let the battery recover from the repeated cranks, logs and... I've hit space bar before saving the...

Thanks for your reply. Im not wanting to swap modules just yet, I dont want to create some boo boo mess that is going to cost a lot of money to fix, i.e. new TCM or ECM. I was reading on one site,...

I don't understand what is keeping the crank signal from reading when key on crank per hp tuners scanner display... i think this is the cause of the long crank.. its like its relying on the cam...

thank you for your reply, this is not a stock vehicle, a pullout from a 2019 tahoe stuffed in a 2006 bmw.

vats 1 and starter diag disabled.

fuel pressure is good 72 psi. almost like it does...

I have a l83 swap that's from a 2019 Tahoe, motor and trans. Paid the credits and unlocked it and starts and runs .... and am not liking it compared to my e92 ecu with a 2014 operating system.
...

bumping for a solution on an old thread.
Anyone come up with theories or solutions to resolve the extended crank? any pids to look at? Ive started another l83 swap, and it has the same long...

nailed it. the aftermarket tube is a larger diameter than stock and it makes it do that. Mine would max out, and it would then idle low and the exhaust sounded different... i forgot, but if you...

Hi, finally about ready to fire the swap up. After several searches, instead of making my own post, thought I would reply under the mod's post for guidance before buying credits.
the swap is a real...

just browsing the thread, and its from January and the thread wasn't updated... was the harness from the same engine, re worekd, or did you buy the hanress somewhere else? There is a different high...

Dakota Digital STA-1000. no clue why GM has no BCM designed for engine swaps :(

under System/General tabs, Vehicle-> VATS Algorithm (ECM 731) has 3 options

Opel
PPEI3
NAO

when disabling vats, whats the difference.

In the past swaps, I would disabe VATs 1 (only...

how many do you need, what size wire. 20ga or 22 ga

Sounds like a wiring problem or sensor problem. Brake pedal and ambient faults are normal for swaps. Intake, fuel and oil sensor are not normal. Check wiring first..

Thank you for the input. I will do that and see what it does.. man now that the truck idles like it should, and dives like it should, holy cow it's so fun..

thank you , 5FDP, kevin87turbot and ahmedabri97!! spot on. After adding a bung to the header for the wideband sensor, set the tune up like in the youtube video/instruction and started logging the MAF...

what does their low side fuel system look like? I got my 87 Silverado / 2015 l83 on the road 2 weeks ago. I used a TI automotive F10000305 or 302 version. used since the stock pump and my adapter...

Ill look into the AEM OBD2 wideband once i get back inside, Im back outside fooling with it.

So, after watching the video

I only have the base model hptuners, no pro box. On my ls1 bmw, I used the 14point7 controller and sent the output to the a/c pressure sensor which worked great. So I was thinking of using the Fuel...
