Default 25 CELs?

ok so i hooked up the computer to the hondata to figure out what the code was, and it turns out there was 25 different CELs at once. another thing that was a bit wierd was the datalogging was completely wrong. like the vss was at 436 mph, which is obviously wrong. what would be causing this all to happen. any ideas are appreciated

ehhh....you check all of the ecu connectors and make sure they're in well? how about the cable going from the hondata box to the ecu?

sounds like a pretty major problem...

Lol.. Write down all the codes, then reset the ecu and see which ones come back, then go from there. Is ur car obd1 or obd2? Could be the codes were never cleared from the ecu.

Pull the cover off and make sure the chip is fully in the socket. Then make sure all the connections on the board look good, something came loose or blew it sounds like.

Is the LED on the hondata box on or flashing?
