WTF with ecu chipping
Previously i chipped some ECU´s, but now i have a problem with one i chipped for a friend, it doesn´t work at all. Without the jumper it works as normal (duhh), but with the jumper the car limits at 45k in any gear, try different programs also those ebay JUN, Spoon chips, but have same problem.
Which could be the problem, the resistor have a side?
Note: Bought parts on an electronic store
2 0.1 UF disc capacitors
1 10 KOHM resistor (1/4 watt)
1 nte74hc373
socket, jumper and chip

If it's not a soldering problem, maybe its a desoldering problem. Check if there is no broken internal wire. I broke some on mine and I had to bypass with an external wire, but don't try this at home, i'm a professionnal

Yep, overheat could be a problem. If you burned the board it can be worse than in my case. I was seeing where I broke wires, but when you burn a board its harder to know.
Try to follow the printed wire on the back and use a multimeter to see if all the wire have connectivity. Can be laborious, but at least you'll know what is the problem.
I should take pics of mine, I like the way I fixed it
