Hey guys, any of you had any luck with swapping to discrete fans? Based on Gen 4, I know how to do this but for the life of me I can not get it to work on this conversion. I can get PWM to work but thats very hard on relays... LOL I don't need anyone to look at a file, just need to know if you guys have had luck.

Here are stock files though... :mad1: Never mind, they exceed the size limit at 4megs each.


Swap is a 2014 DI 4.3 and 6L80 in an Ultra 4 4800 Car

Update. Heard from 2 different sources, I would call very credible, there is no way to make discrete work on the E92 as of this time.


Also, this was bench flashed with nothing special added to make it work. I have been getting a lot of questions on bench flashing lately. I built the harness here, the only thing I made sure was there was IGN to the serial comms wake up.

If you have a PWM signal then what about using a solid-state relay to control the fans?

Trying to keep electrical as compact as possible. 2 engine fans and a trans fan. Rig will be raced in extreme conditions, everything has to be simple and replaceable fast.

Change the fan control tables to either 0 or 100%, only way that the PWM won't screw with things.

Tried that road. Cooked 3 relays in 5 min. There is still ramp up and down to deal with.
