Re: MS2 new documentation discussion
Why there is no mentioning of setting up 3 wire idle valve in the hardware manual?
Also in setting manual page 55 point 4 a ms3-pro is mentioned instead of ms2?
I think it's a good idea to add a table of pin usage similar to the old manual
*Also the manual idea is great keep it up guys

Re: MS2 new documentation discussion
Hi james,
I think it would be a good addition to clarify even more the outputs that fuel trims tables are affecting.
Right now the manual says fuel trim table 2 adjust injector #2. I think it would be good if it said fuel trim table 2 adjust injector #2(assuming wired to injection output B) or something similar to be extra clear in what cylinder is the trim table affecting firing order of the engine.
Edited*** fixing mistake pointed by Jean.

Re: MS2 new documentation discussion
MS2 has no concept of firing order so the trim tables go with the injector channels, not the cylinders. Do not confuse what the MS3 does with what the MS2/Extra code does.

Re: MS2 new documentation discussion
In that case is even more important to clarify it in the manual don't you think? I personally jump a lot from ms2,microsquirt,ms3 and ms2 extra firmware lately have been change to be mimic ms3 firmware. I think it would be a good idea to make emphasis in the details that are different now that the documentation is been revised.racingmini_mtl wrote:MS2 has no concept of firing order so the trim tables go with the injector channels, not the cylinders.

Re: MS2 new documentation discussion
Something to note concerning Bosch single coil ignition modules...... There are 2 flavors, the 0 227 100 124 that is already documented and a 0 227 100 137 that came on 85-92 CIS and CIS-E cars (at least in the U.S.) The 137 module uses Pin 6 NOT Pin 5 for the spark input signal. Otherwise it's the same.

Re: MS2 new documentation discussion
ANy chance of including in the docs a shift light option for one of the programmable outputs?
Correctly identify your MS ecu here

Hi James,
In Megasquirt-2_setting_up-3.3 section 3.4.6.2 there is a reference to req_fuel % for AE instead of ms adder.
Thanx.

Re: MS2 new documentation discussion
James, those docs are unreal. The other night I started reading through some of them again and I'm really impressed - well done and a BIG thanks for doing such a great job with explaining things in a clear and logical manner. The layout is great, the pictures are awesome and the diagrams are really high quality. I work with a lot of documentation on complex subjects and I know good docs when I see them
I saw that you started implementing a change log in one of the docs (the Microsquirt Hardware manual) - this is great as I printed them all, hole punched them and bought a large binder to put them in. Not a small task in some respects. One more suggestion?
What I was getting at, and probably wasn't clear on, when I requested a change log earlier, was a reference to the actual page that was changed. The idea being this;
A user comes in, prints the docs, and since the time of printing they get revised. To determine what has changed, and what pages should be replaced, the user just checks the title page with the revision/date and then checks that against the change log. If the change log showed what page numbers were revised then the user could just print off only the changed pages and replace only the ones that were superseded.
I don't know if that adds a lot more work on your end but it would make keeping printed docs up to date much easier. I really love the idea of proper centralized documentation - it's sorely needed. As a new user it's really tough to find information that's accurate for these products. A giant thumbs up for undertaking such a massive endeavor and for doing it well.

Re: MS2 new documentation discussion
Spotted this small typo in the new manuals, from this link -
http://msextra.com/doc/pdf/MS2V30_Hardware-3.3.pdf
They are shaping up very nicely!

Re: MS2 new documentation discussion
Documentation is coming up nicely
A few thoughts on MS2 documentation:
I was working on a 3.57 board which I dont work too often. I was adding a few spark outputs to the board and I was not sure about where should I take the signal from. When I got to the 3.57 hardware manual, the spark output diagram is the 3.0 diagram, not the 3.57. I had to refer back to the old documentation to find this diagram:
Another thing I find a bit confusing is the following: In the programmable outputs page, the circuit is very clear, but the output table is not. There are a few pins that cant be used as programmable outputs, or not at least with software or hardware modifications. I dont really have a problem with this as im experienced in what to use for each thing but somebody not as experienced would be easily confused. It would be GREAT if below each circuit, you would include a description on what processor pins you can use for the circuit. The current description is a bit general.
Thanks for the great work. Keep it up.

Re: MS2 new documentation discussion
I'm using the Megasquirt 2 Setting Up guide and in section 2.18 it relates a procedure to verify the tooth #1 angle so that the timing is exact (fix the ECU at 0 degrees and then crank the engine with a timing light to ensure TDC is really TDC - If it's not, adjust tooth #1 angle until it is)
I did that, found out I was off by 3 degrees and adjusted the Tooth #1 Angle accordingly and re-verified it was dead-on.
Just a little later, in 2.21 it says to basically do it again, this time with the engine running. Shouldn't the timing already be exact from doing the section 2.18 steps? Or does it really need to be re-visited again?

Re: MS2 new documentation discussion
Yes do it again with the engine running. Even with the plugs out an engine on the starter is speeding up and slowing down constantly with load. Usually more noticeably the fewer pistons you have. This makes the first time less accurate.
Find the Manuals up top under Quick links: Manuals.

Re: MS2 new documentation discussion
Crap - that's not easy/possible in my case (motorcycle). What I have is just a small plug that you remove and the only marks are for TDC and one other for valve lash (I think). It's a tiny hole and if the engine is running you get a lot of oil spraying out of itslow_hemi6 wrote:Yes do it again with the engine running.

Re: MS2 new documentation discussion
Ernie,
What I've done before is get some clear rod, and turn a threaded portion on it, and made a window, but it's quite hard to see the mark underneath then, and the strobe reflects off the acrylic especially on smaller diameters. In the end, I gave up, and just wore a pair of clear safety specs, and spent as little time over the hole as possible, and always had some blue roll ready to wipe the glasses clean again after they got spattered!

Re: MS2 new documentation discussion
Having 1 PDF is great, I have looked and couldn't find some things I needed.
No mention/wiring diagram of how to connect a BIP373. I finally found on another site that there is already a 100ohm resistor on the line and only needed an additional 220.
No good diagrams of rising/falling edge on a VR sensor.
Lack of detailed information/explanations of many tunerstudio items. With the description of "almost ever install uses this method" doesn't give me enough info on what the function actually is.
