This is the final firmware version (2.7 March /2022) which RobR (RIP) released for the EBL flash system as used in our GMC motorhomes.
The Zip file contains instructions on how to preform the update.
Note that this firmware version requires What's Up Display (WUD) Ver 3.1 which is the second download file in this resource.
Below are the firmware updates notes for the EBL-Flash
Note:
WUD version 3.1+ is required when using v2.7+ EBL Flash ECM firmware release
3/30/2022 v3.1 Current Version for EBL Flash & EBL Flash-II
Added N2O % to dump of log, this is to support progressive N2O of the EBL Flash firmware
Changed AFR to cAFR in dump file headers
Added sector erase for SST EBL Flash-II chip (new chip as of Mar '22)
Changed name of built in pressure devices, changed "Autometer" to "Pressure"
Changed so no longer require engine running for ECM Firmware Version display
Moved VE Learn "BLM not at 128" error message up, better visibility
List of EBL Flash ECM firmware changes:
03/01/22 V2.7 Current Version
Fixed delta MAP AE when async dTPS is in affect
Changed digi-dash ALDL to prevent upshift light on some Y-Body cars during idle
09/01/18 V2.6
Changed N2O to be progressive (instead of on/off)
08/15/14 V2.5
Added option flag (LD007b, b4) for IAT/CTS SA compensation, with flag set that table is only based on the IAT
11/20/13 V2.4
Fixed the MPFI small PW compensation (Port Mod only issue!)
10/09/13 V2.3
Fixed idledown on engine stall/restart
Fixed L000A on negative SA (WUD value for SA)
Fixed 3-bar MAP calc for PW term, will run richer if already tuned w/3-bar on a previous version
Changed fan minimum run time to: run time after A/C on and min run
Changed fan routine so PE turns fan off even if minimum run not met
Changed spark routine to prevent false knock retard on a hot start
Changed Proportional Duration to true duration
Added option flag for retaining A/C during PE mode
Added reverse lockout on TCC output
Added 4th gear auto in PE mode SA reduction
Added MPH in PE mode SA reduction
05/01/10 V2.2
Fixed bug in VSS Diag, err 24 routine, will now show a VSS malfunction with no VSS present
Zero out all RPM variables upon key-off
Eliminated doubling of MAP AE calibration parameter when over a TPS% threshold
Added 3-bar MAP boost support (now has 1, 2 and 3-bar MAP support)
Added programmable VSS PPM parameter
Added Crank PW Prime table (widens first one (MPFI) or two (TBI) injector pulses)
Added single fire injection mode (MPFI) for short PW's
Added extended VE table to 8,000 RPM
Added extended Boost Multiplier table to 8,000 RPM
Changed HiWay to allow during open loop operation (option flag)
Changed HiWay to no longer show active when in PE mode
Changed PE & HiWay to no longer show as Closed Loop when active
Changed CCP reporting, if not selected, then not shown as active
Changed High Load/RPM async mode to use RPM/31.25 (to 8,000 RPM)
Changed 400-3600 RPM / 12.5 calculation routine for better accuracy
Changed VSS/MPH calculation to end at 255 MPH, was 200 MPH where it went to zero
