Did a further scan with #VCDS to double check all the #OBD2 #ECU #coding had taken correctly and do some real-time data monitoring, VCDS is way better for this - current draw when the ignition is turned on is as much as 14A !
New #battery holding voltage at around 12,4V with engine off, way better than old one which, barely 12V and sometimes less
Starting engine shows charge current from #alternator as much as 60A, going down to about 10A when idling (which means in future I shouldn't have to worry about #smartcharger overcharging the battery, I may even be able to monitor it this way).
Hopefully this battery lasts another 4+ years as doing all this extra coding is quite a mission compared to older cars!
Got 20A #SmartCharger for lead-acid (and 12V #lithium) #batteries - also has 13,6V constant supply for #coding #car #ECU (so starter #battery doesn't run down whilst getting data from #OBD2)
It works well - but confirmed my suspicions in recent weeks (alas) that battery in my #GolfGTI is goosed (installed 2021 by #VW dealer, presumably as warranty replacement with 0 record on service history, only worked this out from date code)
I'd noticed slower cranking in the cold, battery losing charge quickly and OBD2 scans showing "low voltage warning" codes from LED lighting control.
Will replace it before it bites me in the arse during #winter - #EFB unobtanium but got #AGM on order for fairly good price (will have to change coding when it arrives!)
There's apparently some drama happening regarding automotive industry forcing people to use expensive internet-enabled diagnostic devices when servicing simple mechanical parts like brakes.

But you can also do brake caliper servicing without the expensive tools...

Earlier today I taught my students how to pull a VIN from a Toyota Camry’s #OBD2 port, using #MicroPython and the #CANPico board made by @kentindell.
Fun was had by all. Students were very impressed. Their next assignment will be to pick any other available data from the car and pull that.
Shootout to the main #ECUTweaker developer , I just tried version 2.6.1 ( with the V3 database ) and I was able to display the Engine Control Module parameters consistently ( one driver and myself in the passenger seat monitoring the boost pressure demand, the actual boost pressure as well as turbocharger command PWM - leak after the charge air cooler throwing the car into limp home mode more and more frequently ).
What i most miss from Citroen XM? Fuel gauge. I always knew whats up with fuel: how far i can go, how much litters i need till full tank.
After that i drove cars with dumb E-1/2-F.
I hate that.
Ok, now i have car with some electronic in it, it can display whatever engineers can imagine.
It shows DTE - distance till empty. FCUK. Give me litters! 😡
I even cannot found how to change dash to show remaining fuel.

Don't feel stranded, every #ecuprogrammer 'could' be using same #ECU #pinouts 🤷♂️! Kindly don't just cram, but understand #howitsdone #HapaUjanjaTu
