no_skip_pulses

Post by Black99rt »

Hello, I was trying to do this .ini mod

http://www.msextra.com/viewtopic.php?f= ... ead#unread
OK,
I added some debug code to study this issue and observe 8 tach pulses in before the code starts to squirt fuel. That's four revolutions on a 4 pot. I now appreciate the problem!!

While I am looking into the code to optimise it, one patch that can be applied is to tweak the ini as follows

In your megasquirt-ii.ini file find and amend the following lines.
e.g. C:\Program Files\Megasquirt\Megatune2.25\MtCfg\megasquirt-ii.ini

approx line 118
no_skip_pulses = scalar, U08, 1, "", 1.00000, 0.00000, 1.00, 255.00, 0 ; * ( 1 byte)

approx line 1241
field = "Skip Pulses", no_skip_pulses (remove other field)

Then re-open Megatune and find the "skip pulses" on the "tach input/ignition settings" menu. Set this to zero or one.

Please report if this helps.

And I can get it to work in MT on my desktop, but not TS on my desktop (with the example projects) I wanted to try it here before I tried it on my real project on my tuning laptop, which only has TS :D

When I mod the .ini, the field becomes "available" in TS, but when I go to burn or close the dialog it says no_skip_pulses must be>=3.

Which ini did you modify? The one in the ecuDef or the projectCfg folder in your project?

Can you post the ini you modified?

In the project config folder, like it says to do for MT. I attached the modified file.

Search for "no_skip" the first two results are the lines in question.

That ini looks fine, but the error "no_skip_pulses must be>=3" is true for the original ini, So I'm thinking the ini you are editing must not be the one referenced. Is there more than one ini in the projectCfg folder?

What I would recommend is creating a new project, for ECU Definition, click "Other" and browse to the ini you are using in MegaTune that is working.
The New project wizard will copy that ini to the new projectCfg folder and place the right reference to it.

Ok that works. When I do it on my laptop, I'll check in the project properties tab to verify which .ini it's looking at, then go change that one. Thanks.

just to point out, I found that sets the min to be 1
I posted this line which will let you set to 0

Code: Select all

no_skip_pulses = scalar, U08, 1, "", 1.00000, 0.00000, 0.00, 255.00, 0 ; * ( 1 byte)

Yep I'm aware, thanks for looking out, I didn't want to get too aggressive on my first foray. But user feedback indicates that 0 is safe.
