MS-II, Megaview, and tour of IBM Research

[cygnusx1]

On the MS-II you cannot edit maps.

 

Quoting the Megamanual:

MegaView has the following features:

All runtime parameters are displayed in a scrolling fashion on the display. In Runtime Ticker-tape mode, the parameters displayed for MegaSquirt-I include:

time since start [sECS] up to 65,535 seconds (216-1), over 18 hours,

current engine operation state [ENGINE] (CRANK/RUN),

warm-up [WRMENRICH] enrichment (ON/OFF),

acceleration [ACCENRICH] enrichments (ON/OFF),

engine speed [RPM],

injector pulse width [PW(MS)].

intake manifold absolute pressure [MAP(KPA)],

barometric pressure [bARO(KPA)],

coolant temperature [CLT(F)],

intake air temperature [MAT(F)],

throttle position sensor voltage [TPS(V)],

battery voltage [bAT(V)]

Exhaust sensors voltage [EGO(V)]

EGO correction [EGOCOR(%)],

air density correction [AIRCOR(%)]

barometric pressure correction [bARCOR(%)],

current volumetric efficiency [VECOR(%)]

warm-up correction [WRMCOR(%)]

acceleration enrichment correction [ACCOR(MS)]

all computed enrichments [GAMMA(%)], and

 

For MegaSquirt-II, MegaView2 code lets you change:

CRNK ENRCH_L,

CRNK ENRCH_H,

AFT WRM PCT_L,

AFT WRM PCT_H,

AFT WRM EVTS_L,

AFT WRM EVTS_H,

IACSTART,

PRIME PLSE_L,

PRIME PLSE_H,

REQFUEL,

DIVIDER,

ALTERNATE,

INJOPEN,

BATTFAC,

INJPWMT,

INJPWMPD,

INJPWDTY,

ADV OFFSET,

AMC Option.

MV2 does not allow you to change the VE tables (because then we'd really want to also be able to tune the AFR and spark tables, and with 144 entries each, it would take almost forever to step through all the entries).

 

It takes about 45 seconds for MegaView to scroll through all the variables. The automatic scroll mode can be frozen at any time in order to monitor any desired variable.
