First MegaSquirt 3 datalog and msq
So last night :brain: got an MSQ file setup for MS3 without any conflicts. I then promptly stole it and got my car started on it.
Today I modified his msq with my timing settings and put in my fuel and spark tables. I then went out and burned them to my ms3. Car then started up after a few cranks and seemed to idle well. Next on my to-do list is to check and make sure my timing is set correctly and then work on startup settings and tune. Here are links to my datalog and MSQ files if anyone is interested in looking at them. Datalog MSQ file I take no responsibility if you use the MSQ and blow your motor. |
Nice :)
This is the first running installation from the first batch of MS3s released. Though I expect there will be some more after this weekend. |
damn. he used MY map...I would be running it today as well but I got called into work :(

I was simply shooting to get the first Miata running on MS3. Knowing I most likely have the first running one on a car out of the production batch makes me feel even more special. I am going to go get myself a cookie.
Hopefully tonight and this weekend I get some road time on the car and can iron out some more bugs with it. Scott, it actually doesn't just have a 2-step, but has a 3-step launch with burnout mode. :skid: |
in for ms3 pnp.
|
I'll just consider mine running first cause he straight up loaded the damn MSQ i sent him ;)
I think Hustler would like the AFR safety system. |

Brain, when will you start accepting MS1's to be upgraded to MS3? :)

wtf.afr safety system? I don't really need that, but I'd like some more ve table accuracy. I guess there is nothing new for knock detection?

Edit: I'm also thinking about building a little circuit to convert the TXS output into something MS1 can use. Nothing fancy, just a little 555 timer similar to the one in the MSExtra hardware manual. In the event that it works, I'll post a write up. |
God, if I knew it'd take me this long to put in my new motor, I'd have waited for the MS3...so, uh, anyone wanna buy a MS2 daughter board?

Actually starting with MS2 there is software selectable knock input parameters. You could take a TXS knocklite and plug its digital output directly into the MS (at least in theory). Once I upgrade, I plan to test it out.

Daymn, I've been planning to do this for quite some time!! I've just been lazy scoping the output.
Got any specifics on the output? Cheers! The way I figure it, as long as it is outputting what it sounds like it is, at most the signal might need to be inverted and trigger a timer to hold the line low for a few hundred uS. |

Okay, up and running. Am I still #2?
|
My tip in settings are definitely off right now. Here is a datalog of me idling and just hitting the gas. I will be doing some reading about tip in settings tomorrow but if anyone wants to take a look and give me some pointers it would be greatly appreciated.

get sequential going, you need barely any AE then ;)

Quite probable.
Your VE table probably isn't dialed in yet. No use in playing with enrichments until after the VE table is nailed. Now onto the negatives. Tonight as I was going out to my friends house I started having problems with my MS3. My tach started falling randomly and it felt like I was not getting spark. It got so bad that if i came to a stop my car would almost stall out. Giving it gas in any gear would do do next to nothing and it was hard top get above 2500rpms. Unfortunately my laptop battery was dead so I did not get a log of it. I plan on trying again in the morning and will see what happens. |

You would need to relocate the power filter capacitor, the case would need to be clearanced for the USB port, and it might be a little bit tough to work with the SD card slot, but it looks otherwise easily doable for anyone who wanted to upgrade their MSPNP.

I have a PNP. Is posible update it to MS3???
Thanks |

Since the MSPNP is at its heart a v3.57 board, then yes it should be possible to upgrade it to MS3, but due to lack of time and product availability, we've not actually tried it. Should be a matter of plugging it in, changing some jumpers around, and fixing up a basemap. We're out of MS3 cards, and what I've heard through the grapevine is that it will be ~2 months before we see any more. |

Sure, but if you can't set a period prior to spark time per cylinder then its a waste of time. Real knock detection would make MS so much more attractive...but I'm not sure that I'm willing to put any effort into it. I've already demonstrated with lap times that I have my hands full at 250whp.

The 2.0 firmware's planned features include knock windowing. So we'll be able to window knock detection using that firmware's (also planned) angle-clock timing code.

Ken <fingers crossed> |
You man using it as a true ADC instead of just an on-off digital signal I assume.
I think you can do that now as long as you're not trying to let the MS actually use the knock signal at the same time... You can just log the generic ADC input right now. Was there something more that you wanted? I see that request as more or less unrelated to the knock windowing feature. Ken |
Last time I asked I was told the response rate wasn't quick enough, I do mean for the MS to do something with it too if possible.
|
Lars, did you use my timing light to get this thing working? If so, I will take credit for helping. lolz.

My new diyPNP feels so old now. Always a bridesmaid...........wait, I mean........
