How do you tell the difference? Does it even matter?

 

it will give a CEL of 19 which is Lock-Up Solenoid Valve.

 

Is there anyway to tell before installing?

 

theres some #'s in the bar code but I'm unsure on how those go. Sorry

 

ok thanks anyway

would my car run good with the auto ecu?

 

This is from Hondata.com

"Automatic ECUs are designated with a 5 as the second to last digit in the bar code (after the 'A'). e.g. 37820 P28 A51. "

I believe the 5 speed ecu's end with an 8. My old crx si ecu ended with A080.
So 5 auto, 8 standard. Please correct me if im wrong

 

the car will run fine with a code 19 drove for months like that with my ZC, hell the car did its best NA time with that ECU...

 

your wrong i followed these directions when buying my pg7 and the one i bought doesnt even have a 5 in it anywhere and it was an automatic but i got it for 50$ and it still works but now i get cel 19 all the time

 

I thought ECUs said "A/T" or "M/T" on them. I thought I remembered seeing that.

 

thats on the internals close to the chip
not all had them
