MS2 new documentation discussion

[lagos]

I also like the idea of a pdf as most of the time I have no internet connection on the laptop while on the road. HTML is not that great for offline reading.

James I believe you 've done a very good work. During the last month I am seeking info on several different setups and all I have to do is google "megasquirt something" and the relevant page appears! Makes more sense now than some months ago..

Hi James.
I think the new manual is a good thing. Once the MS is installed it gives the new user a good guidance through the numerous settings in tunerstudio.
I have two ideas/questions/suggestions:
1st: I noticed that the Section "Idle"/"Idle Advance" shows mostly non populated diagrams or diagrams with "Flat curves". Do you think it would make sense to replace them with some examples of well working curve shapes? I think me (and many other users) could probably provide some examples. This could give unexperienced users some better "staring point"

2nd Topic: As already said at http://www.msextra.com/forums/viewtopic ... 57#p395757 . The EAE tutorial still sounds a bit theoretic to me. I assume many user despair of using EAE because they do not realize which parameter has which effect to Engine/AFR.

Values during accel/decel.
To my eyes the EAE manual could need some improvements. Because the EAE stuff is not bad at all. So it's worth to encourage more people to use it. I think the key point is that at EAE it is not quite obvious which value causes which behavior of the algorithm.
So maybe it would be good to add something like

"This will happen if you change the referring EAE values:

ADW Coefficient:
Large values = Much correction, big amplitude of EAE gauge at engine load change (60-140%)
Small values = Less correction, small amplitude of EAE gauge at engine load change (90-110%)

SOW Coefficient:
Large values= Less correction at engine load change (90-110%), Gauge goes quick back to "Zero position" (i.e. 100%)
Small values = Much correction at engine load change (60-140%), Gauge goes back to "Zero position" (100%) very slowly..."

At least that's what we (not only me but in cooperation with some other MS user) have found out when playing around with EAE. With this guide it was much easier to get EAE running.
Any thoughts?

However, good job so far, James!

I created another draft document.
http://www.msextra.com/doc/pdf/MS2_Sett ... -06-20.pdf

This is intended to be the first manual in the series covering initial setup and configuration.

It pulls content from existing online manuals plus some MS3-Pro manual content.

Excellent draft James.

I think it will be advice to say "If MAT, CLT, TPS sensor inputs are unused they need to be connected to ground."

True. I think I already included that in the hardware manual, but it is worth repeating it.

Overall, now that there are drafts for the three main manual topics, I'd really appreciate general feedback from everyone.
I'm aware that board assembly and hardware mods for V3.0 and V3.57 are not yet covered.

Are all other topics covered?
Are there any topics in any of the current online manuals that ought to be included or considered?

Hi James,

From your last draft I found some mistakes :

Paragraph 1 : Introduction =>

This manual covers general setup and configuration information that applies to the whole Microsquirt-2 product range, it should be used in conjunction with the TunerStudio Reference Guide and the Hardware Guide for your product.

you may replace Microsquirt-2 with Megasquirt-2 in the main text.

Also, i will display paragraph "1.1"before paragraph "0" because user may stop to read the manual at "0" if he is familiar with ECUs and don't read paragraph 1.1.

In paragraph "0" you have this phrase :

6. Connect your Megasquirt to a 12V fused supply either in the car/bike/etc. or on the bench.

Regarding paragraph 1.1, I will remove /etc. because All parts are sold for OFF ROAD RACE-ONLY ground-vehicle use only

In this case I may use

6. Connect your Megasquirt to a 12V fused supply either in the vehicle or on the bench.

Best regards,
Manu

OK, I've fixed those. Thanks. I'm sure there are plenty of other areas that can be improved.

James I could not find in the ms2 manual configuration draft info on the coil setting for equivalent fc fd and rx8 mode(old code setting name). I saw the rotor and injector configuration but nothing for the coils. If it is in the manual in other section I recommend to be move to the rotary ecu configuration of the manual.

The wiring details are in the hardware manual, but yes it likely makes sense to include the settings in the setting up manual too.

Thanks for looking.

James does mega squirt still supports toyota multiplex? I worked in a 7m recently and could not find any information for the stock setup. What output mod does it need/use? Ended up doing direct control but I would like to use the stock system to retain the tachometer in a plug and play configuration no mod to the wiring need kind of installation.

[juansh2385]

I found information in the microsquirt hardware manual. The multiplex signal output is a 5v output does test mode works correctly for multiplex output?

It probably works, but I've not tested that.

what are the output for 6 cylinder un ms2? i connected d14 ti igt d16 to spark A and d15 for spark c (moded for 5v output) and I can not make one of the spark output work neither in test mode or starting the car do I need to use J10 instead of d14 and use d14 and d16 for spark select? I really have look the draft and the "normal" manuals and can not find that information.

I haven't got that far in the MS2V3.0 manual yet, I'm up to section 5.3

Jean I am talking about the output for a Toyota 6 cylinder multiplex module it has 1 igt signal and 2 spark select output to select what coil to fire.

No problem great work so far really thanks for taking the time to do this.

I didn't make the link with your previous post. However, it would be more obvious if you had started a new post because this is not a documentation discussion.

Back to topic. I am not sure if I miss it but in the microsquirt hardware manual I did not see any reference to the use of shunt resistor etc. I think it's worth mentioning because most of the microsquirt that I have installed ended un needing them.
