Bench top Engine Simulator for the P01/P59 Pcm

[DavidBraley]

Thanks MudDuck514, I do hope it does last and/or I don't fry it!

I highly recommend following this character if you are new to electronics (like me!). I find his explanations to be super helpful. I was very surprised to learn that a circuit powered by the USB port on the desktop computer causes the circuit to be mains earth referenced, and what can happen... Super important to those of us programming PCM's on the bench. Normally, the PCM is powered by a floating power source (car battery). But when we use a bench top rig, things can get damaged if we are not careful.

Hi all,

The 2 things I was taught regarding this is :
1) Only connect ONE ground - from the A channel input; and
2) NEVER connect the ground clip to a "live" circuit - ONLY the "DC Ground" of the circuit under test!

Great info ... Thank you!

Pour it on!

Hi Gampy,
I'd like to build one of these signal generators. It appears you were able to find the software. Can you provide any more details of what I need to do/buy to build one? It might take me a bit to understand but I won't give up

If you're talking about the Ardu-Stim??
The only purchase (if you don't have one) is an Ardunio board, like a Arduino UNO.

The software (LibreEMS Suite (Ardu-Stim) and SerialUI v2.1.6) is linked to in the second post, paragraph 6 and 7.

Hiya Gampy,
I need to read better, lol. I skimmed that first page and kinda just saw "database error", "newer might work", "Facebook", "newer versions do not work" so I just kept going. Oopsie, sorry about that.
When I get back to the shop in a couple days I'll see what I have. I just got a PICkit4 a few weeks ago and I know I have some atmel stuff and think I have some arduino stuff laying around so I should be able to build something. Thanks,
-Carl

Thanks Gampy for the tips on this. The Sparkfun Redboard showed today. Quick hook up to my scope just to have a gander at all the different signals that ardu-stim does, pretty neat. Have you tried yours on an ECM/PCM/TCU yet? I hope to try some stuff on the bench next week. Encoded 24x 1x LS1 and 58x(60-2) 4x LS3 pics below.

Well, you definitely know how to use a scope better then I ... My post above of the 24x was my very first use of a scope.

Then Sir DavidBraley had to go and ruin my fun with that very helpful awesome video, now I'm a scardee cat ... Naw, just mucking with ya David.

I was never able to get decent results (with the Ardu-Stim on a pcm), I then figured out I had V6 Os's on my Pcms, at the time PcmHammer was not able to Os swap ... I now have V8 Os's on them, however I have not returned to this project since doing so.

I have been planning to do so, I will do so, it just hasn't happened yet ...

BTW, Thanks for the Screen Shot education ... -(
(Meaning I see settings that I was confused about and might help me)

I am definitely NOT a pro scope user, this 4 channel Rigol has a lot of power and is smarter than me. I just quickly altered some things until the traces were half decent so I could do a snapshot to the memory stick. It's a pretty nice feature, I bet yours has that too. The signal looks pretty "dirty" to me but I also didn't play with it much so I'll let you know what it takes to get the ecm/pcm happy when I get around to it too.

[Gampy]

Sweet, I'm all ears (eyes) ...

Is that a Rigol 1040 Plus?
That is one I had on my wish list, they say good things about them.

Yea, I believe this Siglent can record and do snapshots to usb.
