Everything there is to know about MegaTune Auto-Tune

[Clinton_H]

I just upgraded after using the first version of autotune now i can't get it to work again. I tried coping the ini file over to the custom ini and it's still not working. Any ideas? I don't have the box and autotune on the VE1 tune screen anymore, could someone do a step by step on how to move and where to move the new files if it's not too much trouble. Thanks.

Don't forget that I added the zLimits, too. You could use that to keep the decel leaning inside some reasonable range, say zLimits = 25, 200 and it won't ever go below 25%.

I've looked around several places, but have not been able to find out if v619 will work with MSnS Extra firmware 024s11

Dan,

Build 619 will work, but you'll have to edit the msns-extra.ini a bunch, because I reworked a lot of the #set names in build 555. The left column in the table below shows what the values were, the right shows what they are now... Other than that the 024 ini file should work fine.

Code: Select all

DIY_TechE_NonL          DIYWB_NON_LINEAR
FIDLE                   FIDLE_GAUGE
GM300KPa                DELETED (identical to MPXH6300A)
IAC                     IAC_GAUGE
Innovate0_5             INNOVATE_0_5_LINEAR
Innovate1_2             INNOVATE_1_2_LINEAR
MSpark                  DELETED
PWM                     PWM_GAUGE
TechEdge_Lin            TECHEDGE_LINEAR
WB_NB_EMULATOR          WB_1_0_LINEAR
WB_Non_Above            WB_UNKNOWN
Zeit_100                ZEITRONIX_NON_LINEAR

Clinton,

This is probably because the name of the table editor is not correct in the AutoTune section of your ini file. Grab the whole chunk from http://www.msefi.com/viewtopic.php?p=72083#72083 and paste that into your custom.ini. Then change the line that reads

table = veTableMap ; Should be the map3d_id of a TableEditor entry.

so that it reads

table = veTable1Map ; Should be the map3d_id of a TableEditor entry.

for Extra or MS-II, or leave it alone for B&G v3 MS-I code.

Still don't seem to be able to get it to work.

I am using 024s9 extra code and downloaded version 619 of Megatune.

Bazzer,

The only evidence that you have auto-tune enabled is a check box at the bottom of the dialog. I've just fixed up custom.ini in build 623, you might want to grab that build, copy the c:/Program Files/MegaSquirt/MegaTune2.25bxxx/carMtCfg/custom.ini to your car1/mtCfg/ directory and run with that...

(Oh, my server appears to have been hacked yesterday, so I took it down. I fixed my sig to point to downloads on here on MS-EFI.)

Cheers Eric

I just got it working. I had to put the options in the MS-Extra.ini file rather than the custom.ini file. Then I got the check box.

Many thanks !!!

I put the lines at the bottom of the msns-e.ini file and I got the check box... I haven't tried to use it yet. Should I move to the custom.ini file?

[efahl]

Putting the AutoTune in either place will work, but...

The reason I say you should put it in your custom.ini is because that file is left untouched by the MegaTune installer, so if you upgrade from build 619 to 623, then 623 ignores all your changes in msns-extra.ini (because it's in MegaTune2.25bXXX/mtCfg), but it keeps the changes in custom.ini. If you look in your car1/audit.log, then you'll see the sequence of file reads, and find that megatune.ini first reads msns-extra.ini, then at the end it reads custom.ini, so anything in custom.ini supercedes the stuff before it.

This is basically an ease-of-use issue and should have nothing to do with functionality.

Ah, makes sense... Thanks for clearing that up.
