MS3 new documentation discussion

[jsmcortina]

Having made some good progress on the MS2 documentation, (http://www.msextra.com/forums/viewtopic ... 01&t=53509)
I've now turned my attention to MS3.

There's a first draft of MS3base/V3.0 hardware manual here:
http://www.msextra.com/doc/pdf/MS3baseV ... re-1.3.pdf (EDIT)

This is based on the MS2/V3.0 hardware manual, so some MS2-ism may remain. There are also likely to be gaps and room for improvement.

I welcome constructive criticism and suggestions for additional content or other improvements.

Some serious time invested in that so far! Very impressive James! Would have been nice back in my ms3 days for sure. I have enjoyed having the downloadable ms3-pro manual a lot. Though i have noticed that it definitely is not a living document like the manuals currently are. Is there some way that could be used to allow us to have offline access, but still be able to sync up with you as you make updates and revisions? Google doc-ish?

I have been working on a 1.3 code based MS3-Pro manual as well, just had a couple things get in the way of getting that together. It will be out soon.

Excellent!

James' docs are still valuable to me as well. My old MS3/X box got bumped over into my dad's car. I am still very involved in its future

If there's anything that needs particularly urgent attention, just let me know.

Seriously Very nicely done, I Look forward to the end product!

OK, here's the next one. Lots of good content I hope, but rough edges for sure. I think that section 4 needs re-organising into a more logical order.

I thought it was worth sharing it for review at this stage.

2.12.1


•Alpha-N uses the TPS (throttle position sensor) to estimate engine load.
The TPS can be a poor estimator of airflow, but it can be useful if a MAP/MAF signal is unavailable or unreliable.
Be sure to calibrate the throttle range using Tools->Calibrate TPS before using this setting.

Unless someone else can come up with better wording.

[jsmcortina]

I changed those words - thanks. I also re-arranged section 4 and added some additional content.

I think you have done a good job so far. I had a couple questions:

1) would it be possible to list settings that don't do anything when another option is selected. An example of this would be under Engine and sequential settings. You have squirts per cycle, does that do anything with fully Sequential fuel? Maybe this is a software thing and it should be greyed out.

2) more information on "Fuel Pump and Pressure " There doesn't seem to be a lot of information on it. For example what does it do when there isn't a pressure sensor verses when there is one setup. maybe saying what types of engines can use tis feature. Alternator control is another subject like this.

That particular field is hardcoded into TunerStudio and we can't grey it out.

I hope you didn't take it as a complaint becuase I didn't mean it like that. I thought it might save some confusion with newer users if metioned in the guide.

That's fine, please keep the critique coming. I won't always be able to make changes immediately, but suggestions on ways to make Megasquirt easier to understand are always welcome.

I've just released a draft version of the MS3X/V3.0 Hardware manual and an update on MS3base/V3.0 Hardware manual.

Both available in the MS3 section of the manual index from the Manuals link above.

James

[jsmcortina]

Now updated with MS3base/V3.57 and MS3X/V3.57 hardware manuals too. You may need to hit "Refresh" to see the new content.

Dear James,

I'd echo what has already been suggested that if it is actually possible to stop a non-supported option from being implemented at firmware or TS level, then it ought to be and that if not, it should be annotated somewhere.

For example - injector test mode when running 12 cylinders:- there is nothing to stop you from temporarily switching to "batch fire" or "semi-sequential" and nothing to warn you that it isn't supported.

kind regards
Marek

James, thank you for your very hard work on this!

On page 13/203 in the MSXV357_Hardware.pdf there is this statement

"2. Ground the Megasquirt at the engine block/head using both available ground wires"

Do you simply mean each bundle of ground wires coming from the MS3 and then MS3X connected together as one?

Nope.. that's a mistaken carry-over from the Microsquirt hardware manual.

Thanks for pointing it out. (Now to fix the six manuals that mistake will be in.)
