Collection of calibrations pulled from Chrysler ECUs

"Calibration" is the Chrysler term for program-code/content of the EPROM.

This repository is meant to collect various calibrations from Chrysler ECUs, especially the older versions from 80s/90s vehicles equipped with LM/SMEC/SBEC ECUs.

EPROM can fail depending on their age and various reasons, with these stock calibrations a faulty ECU might be able to be repaired.

To dump the contents of a chip a EPROM reader can be used. This is difficult on SBECs for example, because the PCB is in a putty to protect it from moisture etc.

An easier way is to use MPTune and a FTDI interface. The ECU can be bootstrapped and then have the content of the EPROM transmitted by the microcontroller.

A tutorial for this will come.

The folders represent the P/N of the ECU. For every .bin there is a .txt holding information of the ECU / vehicle.

Some information can be displayed by a DRB II or SnapOn MT 2500 (therefore it is saved in the calibration itself, but I don't know how to extract this information from the .bin)

-- ! Beware, some EPROMS contain the VIN of the vehicle ! --

info-scheme for the .txt:

-information from a DRBII/MT2500 via Module Info-

Year: e.g. 1994

Engine: e.g 3.3L SFI DIS / 3.3L MPI DIS / 2.5L TBI

Emmissions: e.g. BUX TRUCK MODULE / 50 STATE TRK MODULE

Transmission: AUTOMATIC TRANS. / MANUAL TRANS.

Module-Type: SBEC-IIB / SBEC-IIA

P/N-Readout: 04686541-A (DRBII sometimes shows a wrong value, note this separately)

-physical Information of the vehicle-

P/N-Case: e.g. 04686541 (P/N on the sticker on the ECU)

EPROM-Sticker: e.g. A4686541 (sticker on the EPROM of the ECU)

SBEC-PCB Rev: e.g. E / K

AWD/FWD: AWD / FWD (might also be derived from the VIN in the ECU, otherwise count the driveshafts)

EGR: yes / no (might be relevant)
