5 volt ecu modification (for wideband users)

I figured "what the hell" I'll try it... and here are the pics..

its easy really.... for a more complete write-up, go to pgmfi.org

this is for basically all crome pro users.., because on most other editing programs..., you can use the eld input for 5 volts...

http://forum.pgmfi.org/viewtopic.php?f=54&t=5699


p06, p28, and similar obd1 ecu's

remove r5

install a 10uf 16v cap......

negative lead to yellow circle (in my diagram)

(from bottom of ecu, connector plugs to the left)
positive lead through right side of r5, then use same lead and solder to left side of c3... thats the jumper you see in the pics
