Custom AW50-42 Autobox Remap

[HappyT5]

My T5 is finally at about stage zero and now its time to dream and save. Sounds like after the suspension and brake work and when I do the power thing (IDP intake exhaust turbo and chip and stuff), I should explore getting a used auto trans worked over while I experiment with paddle shifters. That way when I blow the trans I've got one that I know can handle the power the other mods do. Sounds like fun to me. Too bad about the reprogramming. I wish I could have two maps like the towing button does. One for economy and one for go fast.

CharlyW, the type of "chip" you describe and the way its erased is known as an EPROM (Electrically Programmable Read Only Memory) these are easy to read/ re-program using the correct kit, to read you simply poll each of the memory locations and it will return a binary code.

To program you usually employ a dedicated device (not too costly) this polls each memory location and supplies the contents for the memory location then another specific program pin is raised to a higher voltage to store the values in memory. This higher voltage burns out/ blows the circuits requiring a memory address bit to be set to a value of zero and leaves the logic one areas alone, to erase the chip exposure to a UV light source re-makes all the burnt out locations setting everything to a logic one value.

The slightest bit of dust/ dirt on the window will cause bad areas of chip memory that won't have been erased which is why I don't tend to use anything other than new chips.

Getting the original values in to the PC lets you map out the values to see whats going on, altering parts of the "curve" isn't difficult if you know which parts of the data correspond to real time control - Mike
