Chip swap issues

[1995 525i]

Hello all!
I recently have been running an EAT chip in my car. I took it out yesterday and put in my factory chip. After double checking the connection I put it back in my car and tried to start my car. For whatever reason, the car wouldn't fire. I took the factory chip out and put the EAT chip back in and the car started on the first try. Any ideas?

Thank you,

Michael

Call up Mark and see if they accidently sent you the wrong chip.

He was running the EAT just fine. This is my EAT chip (?) that I was letting him borrow. It was running fine on his stock chip before the EAT, then running fine on the EAT. It's just when he reinstalled the stock chip that it won't run...

funny that happend to me too...I left the key on for like 2 min then all was well.
Not really sure why...maybe the ECU has to re-learn?

Make sure all of the pins seat properly into the board--sometimes you have to bend the pins back.

I'll retry Thursday. Perhaps a combination of the above mentioned suggestions will work.

Thanks.
