Supercharged Camira..

Craig and Adam\’s attempt at adding an SC12 to a JE Camira wagon

ROM Burning 101..

Posted by superchargedcamira on July 23, 2006

After waiting weeks for these damn eBay EPROM chips from South Australia, we finally got them. This meant we could get started converting the Delco to a ZIF socket for easy “in and out” of test chips. We employed our resident electrical engineering expert (The Greg) for removal of the original soldered chip and the soldering of the new ZIF socket. See the pictures below. We also “tanned” (erased) the 11 chips we got for $12.34. They all turned out good.

Our next step was to burn a AMXY0662.bin onto a chip and give it a go straight off the bat. This bin is widely believed to be toned down due to some Camira owners reporting engine ping. After giving this new chip ago we both agree it made the Camira run like a dog! When I mean dog, I mean it runs completely fine but its for the grandma Camira owners that go for the once a week trip to the shops and back! The original AKFL2168.bin felt very much more responsive and noticely more power. We will dyno both the chips to show exactly what kind of power loss is happening where in the power curve to end the speculation once and for all.

We are now at the stage of getting into the horrible task (or fun depending how you look at it!) of modifying the $5D AMXY binary to get it back to operating like the AKFL plus also modifying the MAP tables for the 2 bar sensor. The reason we cant modifiy the AKFL binary is because the $54 definition file isnt considered public domain. I am investigating the possibility of someone reverse engineering the AKFL binary to construct a $54 definition file so we dont have to start with the AMXY binary ($5D definition) but if we have to then we have to.
