dual wideband questions....

[65looter]

Before you point me to the "search" button, I did and and searched in the forum, unless i am blind...

right,

I am running msn extra with the code 026h4
Dual Table (V8 engine)
Two wideband LC-1 sensors/controllers

When I select "8x8 AFR Target Tables" in Megatune, I only see for VE1 and VE3, but I thought the second wideband was for VE2? no?
So, where can I set the target AFR for the VE2? is there a config file to modify?
Also, how do I log the AFR2 and second O2?


thanks for your time.

Hi
the Dual O2 code is for EGO correction, so it still uses the same VE table and AFR target it simply runs a seperate correcton for each bank of injectors.
As for logging it youll need to edit your msns-extra.ini file, down the bottom of the file youll find :


; These are for datalogging the egt,fuel pressure, GForces, spark angle
; and knock retard. Only 3 can be used at once for MSLVV compatability.


entry = advSpark, "Spark Angle", int, "%d"
entry = egttemp, "EGT", int, "%d"
; entry = fuelpress, "Fuel Press", int, "%d"
entry = KnockDeg, "Knock", int, "%d"
; entry = XForce, "X GForce", float, "%.2f" ; X on X7
; entry = YForce, "Y GForce", float, "%.2f" ; Y on X6
; entry = MAFVolts, "MAF Volts", float, "%.2f" ; MAF on X7

; TEST ONLY - DONT USE
; entry = iTime, "iTime", int, "%d"
; entry = iTimeX, "iTimeX", int, "%d"
; entry = iTimefull, "iTimeFull", int, "%d"

; TESTING
; entry = dwelldelay1, "dd1", int, "%d"
; entry = dwelldelay2, "dd2", int, "%d"
; entry = dwelldelay3, "dd3", int, "%d"
; entry = dwelldelay4, "dd4", int, "%d"

youll need to add 2 lines:

entry = egoCorrection2, "Ego2", int, "%d"
entry = afr2, "AFR2", int, "%d"

also add a ";" infront of 2 of the existing lines, e.g. knck and egttemp,

Phil, I have just tested it, it records the second sensor excellent.
