ECU stop to read chip
 

**Setup LS turbo with 450cc and uber
**Note: I use the car at weekends only and i disconnect the battery every week

Few weeks ago when i was cruising with some friends the car starts to fail very bad, throwing a lot of black smog. I stop the car and disconnect the battery for some minutes and i connected again, and problem gone.

Next week the car starts ok but some hours later do the same, i do the same battery thing but the problem came back again quickly.

Yesterday i start the car and starts failing, so i think that was the jumper maybe, so i change it but problem aint go.
I remove the jumper from the ecu and the car acts the same as with the jumper
Then i burn again two different chips with same program and i try with both but didn't works.

I put back the stock 240cc and the car starts ok, with and without the jumper :(.

Wich could be the problem?

Bad resistor box?

Ohh, when i put back the 240cc i also remove the resistor box and leave the car as stock without charge pipe.

But im going to check the resistor box on a friend's car ;D
