Memcal ID codes

[stocky]

This is off another forum, but I felt it might be useful over here too. These codes can be found on your memcal inside your ECU, on the silver sticker. Thanks to the person who originally wrote this



VN/VP

The Holden VN/VP Commodore range was produced between Sept 1988 and Jul 1993, they used the 1227808 ECM throughout these years, essentially a 1227165 minus the SXR I.C, as a result they only have 160 baud serial comms (which for a 93 model car is pretty poor!). The 5.0L V8 engine is Holden's own design, the 3.8L V6 is the Buick derivative, both are MAP based PFI. Auto trans is the TH700R4.

Program I.D Descriptions:

$5D = First VN V6 & V8 release.
$A5 = Update to $5D (Late VN).
$B1 = Minor update for VNV6 & GrpA V8.
$DB = Seperate closed loop idle timer, Torque management spark added, for GrpA V8 & HSV's.
$FB = Block learn mods, DFCO mods, Driveline spark added (Late VP V6 & V8).
$03 = LPG functions (V6 Only).

VR

The Holden VR Commodore was produced between Jul 1993 and Mar 1995, it used a 16176424 PCM or a 16183082 ECM, again fitted with the Holden 5.0L V8 or the 3.8L V6 (Which was much more refined then previous versions). Both engines still being MAP based PFI, Auto Trans model got the full electronic Auto (4L60-E). They also gained a security system that was integrated with the PCM/ECM. Both PCM/ECM now communicate at 8192.

VS

The Holden VS Commodore was produced between Mar 1995 and Sept 1997, it used 3 different ECM/PCM's depending on the Engine/Trans Combo. Still with the Holden 5.0L V8, however the 3.8L V6 was reworked and now carried the "Ecotec" badge, it also used a frequency O/P MAF and went to Sequential Injection on the V6. Also retained was the same security system that was integrated with the PCM/ECM, and of course communications at 8192. Auto trans is still the 4L60-E.

Program I.D Description:
The Memcal program I.D byte is located at the hex address in brackets. If this is set to $AA it is possibly not a stock calibration.

$51 = VS Ecotec V6, Auto and Man versions. (0x2008)
$58 = Like VR's $11 release but VS Theft Deter Implemented. (0x6008)

$5B = For HSV's 5.7L V8 (Manual). (0x0008, 0x8008 with memory offset)
$76 = VS LPG Release. (0x2008)
$83 = VS 1996- Powertrain modifications. (0x6008)
$84 = For HSV's 5.7L V8 (Automatic). (0x6008)

VT



The VT Commodore was the all new update to the VN-VS Models, engines remained the same (Except the Holden V8 gained an Air Mass Meter system and Sequential Injection). The Auto Trans (4L60E) remained, the rest is new... The mid 1999+ models had the option of two versions of the "Detuned" Chevrolet 5.7L LS1 V8 (~300Hp) replacing the Holden V8. The LS1's PCM is Flash Memory based, with Delphi's custom version of the Motorola 683xx, 32bit MCU. None of the LS1 Calibrations will be made available.

Program I.D Description:
The Memcal program I.D byte is located at hex location 0x2008. If this is set to $AA it is possibly not a stock calibration.

$A5 = VT V6 and S/C V6 Release.
$A6 = VT Holden 5L & 5.7L V8 Release.

[stocky]

yeah i think he has it too, but i got it off the SC forum. their tuning thread seems to have lost interest other there so i thought the info might help out more over here

[VNracer34G]

I've got one thats not on the list, it came with the 2nd hand s1 Manual motor/box i got to slot into my VN so origins unknown. It ran sweet for most of the season after the original auto clapped out.
APDL 0288 ???

[delcowizzid]

APDL is our kiwi tune for use without an O2 sensor

[greenfoam]

Yeah not all the NZ ones are on that list

yeah its a pretty rich tune on a well worn in engine dirtys the plugs fast i rip them out and slap in a aussie tune with O2 sensor for instant fuel economy the plugs burn clean nice and quick too.you can pull them out and they nearly look like they did the day you put them in.

definitly, i upgraded with O2 sensor and the arbp, SV3800 tune and it's a noticable difference. the SV tune is a good basis for more fine tuning

BSTH1442 $51 3.8L Auto 16208257 (RFI) Police Version

does anyone kno wat this actually does?
why its different to say a stock chip. ( holden vs commdore series 2 1996 )

without looking i will say just increased idle rpm

Any idea what the differences would be between these:

BLYN8253 $2A 93, 3.8L Auto 16176424 For Factory Fitted LPG System
BMZH1779 $2A 94, 3.8L Auto 16176424 LPG Update from L772126

Going from the VIN, mine is L803587 - so I assume it would have BMZH1779 installed.

This may explain the problems with getting Tuner Pro to work - as everything I've looked at so far has $11 on it.

usually there just minor updates as LPG tunes only seem to ever get 1 update per model.
