Put a 27SF512 chip in it, and switch the wire lead to chassis ground to switch between two separate programs! Comes with a 27SF512 chip. It has a single wire lead coming off of it. This little gem plugs into your 28-pin socket that normally takes a 27C128 or 27C256. Can also be used as an adapter to the Ostrich emulator. Up to 4 switchable programs with separate rotary switch and cable. An HDR5 is available separately if you want to read those stock chips (see product listings).įor many GM/Holden applications, this adapter will allow you to use the AM29F040 chip (C3) to contain your 128k calibrations. This way you can just replace the blue piece instead of prying the old chip loose or messing with a UV eraser. This is to replace those 'BLUE' chip modules in your 6.5L GM PCMs. Soldering required (see product web page).
ALDL STOCK UPGRADE
If the original application accepted a 24-pin chip such as a 2732A, then this adapter will allow you to upgrade to new Flash chips such as the AT29C256 and 27SF512. Soldering required (see product web page).Īllows use of new Flash chips in many GM TBI setups. Allows use of new Flash chips in many GM TBI setups. If you're not POSITIVE that you have the 0.45" spacing then get the 0.6" spacing. Very rarely used! This is primarily ONLY used on the Grand Nationals. Does NOT work by itself! Requires the ALDU1 or APU1 to actually interface to the PC! A replacement chip adapter (G5) is available separately.ĭoes not work by itself! Needs the ALDU1 or APU1 to work.Works with pre-1995 GM ALDL ports. This piece allows you to 'read' or 'reprogram' (with appropriate chip programmer/eraser) those 'BLUE' chip modules from the GM 6.5L Diesel applications. This is basically an inverted G5 adapter. Very durable, and designed for repeated use.įor many GM/Holden applications that have a 32-pin EPROM with 128k file, this device can be used to retrieve the 'stock' calibration without damaging the memcal.
ALDL STOCK DOWNLOAD
Allows you to download your original 'factory' chip contents directly using a chip programmer/reader like the BURN1 or APU1. Plugs into your 'stock' P4-style Memcals. Use this adapter to read the 'stock' binary from your TPI-style Memcal. If the old one measures over 2 volts then it should be fine so don't replace it!

Most units are soldered in, so be prepared to desolder the old one to replace it. Hopefully, you will never need a battery replacement on the Demon1, Quarterhorse, Ostrich2, or Roadrunner. This program is used to control the chip reading / erasing / writing duties of the Burn1, Burn2, Jaybird and APU1 devices.
