I just chipped a romless PG7!!
Hey everybody, i just chipped a romless PG7 out of a 1988 integra. I followed the diagrams and schematics from the gurus at PGMFI. Anyway I noticed that in the schematic made by a guy there called Doc, doesn't show the Vcc +5 voltage hooked up to the EPROM (pin 28), or the Octal latch, (74HC373, pin 20). Now those chips need a Vcc of +5 volts to operate so i'm guessing they should be hooked up??
Maby he just left it out of the schematic because its just self explanitory (and i'm just stupid)?? Someone please clarify whether i should hook these pins them up or not. I will post pics once i'm done the data logging. Here is the link to the PGMFI on the romless writeup. Thankyou PGMFI, i could have not done it without you...and of course i love HMT ;D Help me out! http://www.pgmfi.org/phorum/read.php?f=12&i=899&t=899 |

fyi, you can simply replace the 40pn MCU with a 8051-compat micro and use the A5-free code. I think its easier than the adapter...

My Pocket Programmer II from Xtronics does with a small adapter (also available on the website)

The adapter looks good, turboef9, but i'm not really sure if that would work with a batronix programmer?? ???
