Dummy injectors and coils?

Post by 1999 540i »

I'm trying to fool the factory ecu, I have read the main page about using resistors or old injectors, I was wondering do injectors ran dry overheat? I don't like fires

What about dummy coils? or some other way to fool BMW dumb coils

1999 bmw 540i supercharged no tune yet

Thanks

Can you flash tune the stock ecu? On many you can turn off the error codes.

I don't think having the DME connected to dummy coils will accomplish anything for you. What were you hoping it would do?

As far as the injectors, I'm of the same mind on that pretty much, although a long time ago we surmised that a factory ECU might be looking for an inductive spike. Either way though, when the DME doesn't see the changes in engine operation that it wants to see based on the outputs it thinks its making, I think it will be pissed. :lol:

I'll PM you so maybe we can keep some of the sorts of conversation off the forum that James and the other guys might not want on here.

I don't know how, and there is very few people that can, I wish I could

I'm thinking if i disconnect the trigger wire from the bmw coil (leaving the other 2 wires) that I would get a check engine light, I could be wrong, Does anyone know?

The injectors I know will throw a code,

I think you're going to have so many codes, that these will just be some more to add to the list.

Unless as Paul says you are able to program out the showing of codes, but so far I haven't heard of that being done with ME7.2...?

Me7 for the vws is pretty simple, considering.
