Hi,
I have a problem with my friend's car.
It's a 3.8L 6 cylinder BMW engine with 780cc LowZ injectors.
When the fuel injectors fuse is in place there is no connection between VEMS and MegaTune.
When I remove the fuse the connection is back (need to switch ignition key).
I tried to disconnect some injectors and with only 3 injectors connected the connection is still OK.
It looks like some load dependent problem.
The problem came suddenly today.
It also looks like the injectors are flooding the engine because when I try to start the engine
it comes alive with few cylinders and then immediately dies.
We use PowerFlypack and PWM mode, so no inline resistors.
We also tried another vems with same configuration and same problem occurred.
Regards
Mihkel
