afterburner

I have fsds1.6 and i want to add some afterburner effect to my phantom. I read some tutorials about it, but they were all talking about thrust lever function. I saw no similar function in fsds1.6. Older fs98 aircrafts also have some afterburner effect. Clearly they done it without fsds2.0's advanced features. So, how can i add afterburner to my aircraft with the softwarte i have?
