Re: MS3 new documentation discussion
Hall sensors are not the same as gear-tooth sensors.
Hall sensors detect an external magnet.
Gear-tooth sensors have a magnet built-in and sense ferrous material.

Re: MS3 new documentation discussion
Ok, then the way that whole section is written makes it very confusing. The DIYautotune.com version specifically lists it as a hall sensor but suggest setting it up like a VR. Again, adding even more confusion.jsmcortina wrote:Hall sensors are not the same as gear-tooth sensors.

You didn't comment on anything else I posted, was curious if any of it was good or not?

Re: MS3 new documentation discussion
Ok......can you elaborate as to why you don't recommend it? DIY certainly does and I would guess that the majority of people buying MS are getting it from DIY just as I did. It would make sense to at the very least, acknowledge it in the manual.jsmcortina wrote:The guys from DIYA are best placed to answer any questions about their site.

Keep in mind, my suggestions are based on my own experiences, frustrations and confusion. I doubt I am the only one. This topic was to discuss the documentation and I assumed that meant suggestions to include making it easier even for noobs like me. If the documentation is not suppose to help people like me and only for advanced users, then please say so. Your one sentence response tells me you can't be bothered to take my suggestions into consideration. I am just trying to help future new users with zero background in electronic or electronic fuel injection.

Re: MS3 new documentation discussion
The VR conditioner makes a great all purpose input and works for nearly everything except triggering off the negative terminal of the coil. Our experience is the Hall / optical input circuit requires too much current to trigger and is too heavily filtered (if C12 and C30 are present) to work well with our sensor. But the VR input works great with it.dragbug wrote:

We typically recommend the relay board for some specific installs, but not all of them. We generally recommend it if (1) the car was not originally wired for EFI, and (2) if the car will not be used in an application where high vibration is a concern. On cars with factory EFI, we typically recommend using the OEM fuses and relays to support EFI, and on cars where vibration is an issue, we typically recommend relays on tabbed terminals or other crimp on blocks.dragbug wrote: Ok......can you elaborate as to why you don't recommend it?

Thanks Matt for responding and explaining, I appreciate it. I went with the relay board because my car was not originally EFI and it made sense to use the relay board. I know there are a lot of people out there just like me. I was only posting here in order to see if I could help other people in the future not have to be as confused and frustrated. I know DIY isn't directly involved with the manual but honestly, either DYI should make one or collaborate to make the manual more noob friendly.

James,
I found a typo in section 5.3 of the MS3 ( and MS2) Hardware manual. The picture of the mainboard showing the 6 potential ignition channels has JS5 for Spark E and JS4 for Spark F while the table below it shows JS4 for Spark E and JS5 for Spark F.

Re: MS3 new documentation discussion
Possible correction:
Page 47. Tacho output.
Currently:
"As standard, the MS3X connector 'Tacho' output will provide a 0-12V signal that is suitable for most aftermarket
tachometers. (Ensure that JP2 is in place on the MS3X card.)
"
I think JP2 should be JP3.

Re: MS3 new documentation discussion
Page 212: Photo help.
Optional If you plan on running an idle valve or VVT solenoids from the MS3X outputs, install a jumper wire now.
Solder a wire into the S12 hole on the mainboard and solder the other end onto the 'C' end of D1 on the MS3X card.
This gives all of the MS3X mid-current outputs a 12V flyback clamp and makes them suitable for high-frequency valves.
Whilst not the best photo or work compared to you guys, I've attached a couple if helps.

Question RE section 6.9.11 Non-missing tooth crank wheel with one cam tooth
Page 141 of the new manual states
Typical settings:
Spark mode = Toothed wheel
Trigger angle/offset = 0 (not used in toothed wheel mode)
Trigger wheel arrangement = Dual wheel
Trigger wheel teeth = number of teeth
Tooth #1 angle = tooth #1 angle as determined above
Main wheel speed = Cam wheel
Second trigger active on = Rising (verify with composite logger)
and every rotation of = Cam
Is the Main wheel speed = Cam wheel correct or should it be Crank?

EDIT: PS please mention WHICH manual you are referring to, there are seven Hardware manuals. (In this case they will all have that same mistake.)

Re: MS3 new documentation discussion
Hi James,
First off I just wanted to say how thankful I am for your thorough documentation and the incredible support you and others provide on this forum - I'm certain it will prove invaluable as I get my MS3 setup installed in the coming months.
As I read through the Megasquirt3_Setting_Up-1.3 manual dated 2014-11-17, I took some notes on things I found here and there. I tried to focus on typos more than comma or hyphen usage, hopefully you find this helpful and I'll have contributed to this great community in some small way. Locations are designated by page number, the text in quotes should help identify the location of the typo. Some of the style-related notes are subjective and entirely up to the author's discretion (for example, the Oxford comma), but I thought I'd note them anyway. If there's no note, I figured the error should be self-explanatory. Without further ado, here's my list:

Re: MS3 new documentation discussion
Page 107 of the TunerStudio help manual under the Staging Table section:
"The values in the table determine the percent staged, 0% means not staged at all, 100% means fully staged, and a percentage value between means that ignition is partially staged."
Should read:
"The values in the table determine the percent staged, 0% means not staged at all, 100% means fully staged, and a percentage value between means that injection is partially staged."
Could a description be added to differentiate between what percent staged means when Transition Fully To Secondaries is On and Off? (Ken provided this in another thread: "Even when you are using the table, at "100%" the duty and PW are the same as long as you are not switching fully to secondaries.")
Also, would it be possible to further describe the staging calculation? E.g. what 50% staged means in terms of duty cycle or PW.
I'm trying to set up the staged table to prevent sub 2ms PWs. Knowing how the percent staged is applied would be most helpful.

Re: MS3 new documentation discussion
We should be able to add that, but we can try to get the wording right here first:Could a description be added to differentiate between what percent staged means when Transition Fully To Secondaries is On and Off? (Ken provided this in another thread: "Even when you are using the table, at "100%" the duty and PW are the same as long as you are not switching fully to secondaries.")
In the mode you're talking about, if you're talking about 50% staged for example, it'll scale the primaries to 50% of their original commanded PW (so if you weren't staging at all, and you wanted 10ms there, staging 50% would give you 5 ms), and scale the secondaries up enough to compensate for the smaller amount of fuel being injected by the primaries.
In other words, 50% staged in that mode means that half the actual fuel is coming from primaries and half from secondaries. If the secondaries are bigger, their PW will be smaller.
