Add timing until it knocks, LPG has higher octane so add lots.

Here is my current code, maybe someone likes some inspiration.
I relocated the function and maps since I needed more space. After moving the code I realized I needed the extp command when calling from different sections of code

Code:

	;krkte1
extp #0E1h, #1			;D7 40 E1 00
mov r5, word_381B1A		;F2 F5 1A 9B
cmp r5, #1C2h			;46 F5 C2 01
jmpr cc_c switched		;8D 05
extp #207h, #1			;D7 40 07 02
mov r5, #0D80h			;F2 F5 80 0D
rets				;DB 00
	;switched
extp #229h, #1			;D7 40 29 02
mov r5, #0DC4h			;F2 F5 C4 0D
rets				;DB 00

	;krkte2
extp #0E1h, #1			;D7 40 E1 00
mov r4, word_381B1A		;F2 F4 1A 9B
cmp r4, #1C2h			;46 F4 C2 01
jmpr cc_c switched		;8D 05
extp #207h, #1			;D7 40 07 02
mov r4, #0D80h			;F2 F4 80 0D
rets				;DB 00
	;switched
extp #229h, #1			;D7 40 29 02
mov r4, #0DC4h			;F2 F4 C4 0D
rets				;DB 00

Here is an experimental section for switching LALIUS conditional:
Basically it looks for the lpg switch input first, and then checks if rl_w is in between of 50 and 120. If so, it uses an alternative map.

Code:

	    ;LALIUS call from 0x51ED0 
extp #0E1h, #1			
mov r12, word_81B1A		
cmp r12, #1C2h			
jmpr cc_c switched		
mov r12, #382Ah			
rets				       

switched:
mov r13, rl_w			
cmp r13, #855h  		        
cc_ULE, not_set			
cmp r13, #1400h			
cc_UGT, not_set			
mov r12, #E550h              ;lalius lpg map	
rets				        

not_set:
mov r12, #382Ah			
rets
