The T4M0 & U4P0 calibrations including all the other stock CBAZA calibrations are not optimal by any means. Although the SN94-95 Mustangs did get a
significantly BETTER calibration than the older foxbody ecu's. Some changes can be made to improve overall driveability and performance.
The T4M2 & U4P2 base calibration, is a theoretical stock calibration for the
SN94-95 ecu's created by decipha. This base calibration is adjusted for highly modified naturally aspirated and boosted engines including:
turbocharged, supercharged, and nitrous, as well as bone stock factory engines. This base calibration can be used on ALL 1994-1995 mustang ECU's.
Note: T4M2 is to be used with manual transmission and non-ecu controlled auto's; the U4P2 is to be used with ECU controlled Automatic Transmissions.
PID | Variable | Comment |
SARCHG | Cubic Inch Displacement | Input your actual engine size or scaled percentage if applicable (CLICK HERE FOR SCALING) |
FN 036 | MAF Transfer | Input your actual MAF flow data from your flow sheet or your scaled percentage if applicable, be sure the top value is 16 volts |
ALOSL, AHISL | Injector Slopes | Input your injector manufacturer's recommended values if available or scaled percentage, see Note** below for no data |
FUEL_BKPT | Injector Breakpoint | Input the injector manufacturer's recommended fuel breakpoint |
FN 367 | Injector Offset | Input the injector manufacturer's recommended voltage offset values |
FN 2200 | Borderline Spark Table | See note below. Populate this table with adequate values for your specific engine combination. |
FN 035 | Load Scaling | Populate the Y-axis with your engines expected peak N/A load values (when not in boost), DO NOT PUT IN MAXIMUM LOAD VALUES WHILE IN BOOST |
FN 348A | Crank PW | Multiply the Y-axis as a percentage of the stock 302 cubic inch and 19 lb/hr injectors values by doing, 19/(new injector size) * (new engine size)/302=0.xxx |
FN 1329 | Injector Firing Order | This table must be set to 1-6-4-2-5-8-7-3 for those whom have done decipha's Foxbody to CBAZA SWAP |
FN 1327 | Injector Output Port | This table must be set to 0-0-2-2-2-0-0-2 for those whom have done decipha's Foxbody to CBAZA SWAP |
