I came to realize today I can have a 2 stage smoke unit if I change my function wiring a bit. In the real world HEP mode would have the RPMs locked to a minimum setting of notch 6, which would result in more smoke coming out of the exhaust.
What I might do later is set up the front marker lights and rear green class lights to be connected to the rear headlight function, opening up 1 more function slot for me to use a relay to switch the chuff pin to track ground and therefore set the fan to 100%. That 100% fan function slot would be also mapped to the HEP mode button, so it will set the fan to 100% when the HEP mode is activated.
