How to make RO Engine Upgrades

[Hay]

Hi all, 

I'm trying to make an E-1 upgrade which increases its thrust and slightly raises its Isp, but when I load it up in game it doesn't show up. I tried just copying the existing E-1 upgrade and tweaking it but that didn't work. I tried googleing it but that didn't yield anything useful. Any suggestions?

CONFIG
		{
			
name = E-2			
description = Speculative upgrade configuration for the E-1.
			
minThrust = 2744.064954			
maxThrust = 2744.064954			
heatProduction = 100
			
massMult = 1.0

            
ullage = True
            
pressureFed = False
            
ignitions = 1

            
IGNITOR_RESOURCE
            {
                
name = ElectricCharge
                
amount = 0.5
            }

            
IGNITOR_RESOURCE
            {
                
name = TEATEB
                
amount = 1
            
}

			
PROPELLANT
			{
				
name = Kerosene
				
ratio = 0.3929
				
DrawGauge = True
			
}

			
PROPELLANT
			{
				
name = LqdOxygen
				
ratio = 0.6071
			
}

			
atmosphereCurve
			{
				
key = 0 305				
key = 1 277			
}

			
techRequired = heavierRocketry
			
cost = 550
		
}
	
}

    
!MODULE[ModuleAlternator],*{}

    
!RESOURCE,*{}

    
RESOURCE{
        
name = TEATEB
        
amount = 1
        
maxAmount = 1
}

}

@PART[*]:HAS[@MODULE[ModuleEngineConfigs]:HAS[@CONFIG[E-2]],!MODULE[TestFlightInterop]]:BEFORE[zTestFlight]
{
	

	
TESTFLIGHT
	{
		
name = E-2		
ratedBurnTime = 265		
ignitionReliabilityStart = 0.947		
ignitionReliabilityEnd = 0.999
		
cycleReliabilityStart = 0.9575		
cycleReliabilityEnd = 0.9927		
techTransfer = E-1:100
	
}

Any help is appreciated.
