WTF with ecu chipping
Previously i chipped some ECUīs, but now i have a problem with one i chipped for a friend, it doesnīt 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 |

usually a ---- soldering job

Re: WTF with ecu chipping
are you burning the chip with a 8000 offset?

Re: WTF with ecu chipping
thats normally a ---- solder job as chris said above. try and reheat all the joints for the 28 pin and see if that helps

Re: WTF with ecu chipping
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 :6

Re: WTF with ecu chipping
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 :8 |

i let a frind chip ecu and 3 of them dont work O0
and speaking of jun ect. programs.///chips wtf eGay ---- |

Then Im going to remote it, maybe it works |
Re: WTF with ecu chipping
i wish my honda would run at 45k :-[

That is 1000-1200 ohms. The stripe colors will be brown, black red (1K ohm) or brown, red, red (1.2K ohm) and then whatever tolerance you choose. I use 1 K ohm 1/8 watt resisters w a 5% tolerance. That would be a brown, black, red gold stripe combination. |
