Another autotune question

[Avinitlarge]

Code: Select all

[AutoTune]
#if MS_I
   table = veTableMap ; Should be the map3d_id of a TableEditor entry.
      allowAutoTune = on            ; Displays the check box on the specified tuning dialog.
      corrector     = egoCorrection ; Variable used for correction algorithm.

      ; Tuning block parameters
      ;    Global limits on tuning, outside the box and nothing happens.
      xLimits = 1500, 4000 ; RPM
      yLimits =   60,   90 ; MAP
      zLimits =   10,  200 ; VE

      ; Vertex tolerance parameters
      ;   How close you must be to a vertex before tuning takes place.
      xRadius = 200 ; RPM
      yRadius =   7 ; MAP

      ; Controller parameters
      initialStartupInterval = 1.0 ; Seconds before first adjustment
      updateInterval         = 1.0 ; Seconds between each consecutive adjustment.
      proportionalGain       = 0.5 ; Proportion of (100-corrector) to use for adjustment.
      lumpiness              = 5   ; Maximum percent adjustment above or below neighboring VE points.

What would I change the setting to for use with a boosted engine and how could I use autotune upto 7000 rpm??

Avinitlarge,

You edit the xLimits (to something like 1500, 7000) and yLimits (to something like 60, 200). There's more here: http://www.megamanual.com/megatune.htm#autotune

However, you should be sure to understand what this is doing, as well as the risks of doing this.

I think that is pretty easy to understand apart from 1 tiny part In order to use auto-tune for WOT tuning, you must be running a wide band lambda system (sensor and controller), with an appropriate EGO correction algorithm that allows you to set specific AFR targets (i.e., MSnS-Extra or MS-II). If one of these requirements is missing, then you must rely on seat-of-the-pants and experience.
.

What is this ??

with an appropriate EGO correction algorithm that allows you to set specific AFR targets

Would this be it??

Under "Exhaust Gas Settings"

EGO Sensor Type : Wideband
EGO Switch Point : 2.352
Ignition Events pe Step : 4
Controller Step Size : 5
Controller Authority :75
Active Above Coolant Temp : 71*C
Active Above RPM : 1300


Under "Lambda AFR Setting"

Change EGO Limit above (kpa) : 255
Change EGO Limit (+-) : 5

For VE Table 1 : ON
For VE Table 2 : Off*^(DT)
Control Algorithm for AFR tables : Speed Density
Use Target Tables : Always

I know there is a post about this somewhere but I cant find that either, What are the Minimum Requirements for autoTune?

I have a PIII 500/700MHZ with 512Mb of ram, Will this do??

You're in man! welcome to the club
Minimum requirements are pentium class, windows 95 and higher. I think the slowest I've heared of with autotune is 266MHz 32MB ram running win95, worked fine. lowest powered lappy running Megatune I've hered of is 66MHz, 16MB ram.

I use a P1 150mhz with 32mb running win98. Works fine.
