Bench top Engine Simulator for the P01/P59 Pcm

[Gampy]

Pretty much what I'm doing ... Although I'm working on a breadboard, I'll do a box after I have all I want so I don't have to do a box rework!

JimStim Works verywell for this.

Here's a couple pinout notes(p01, p59) for use when building a simulator. I haven't built mine yet but it's on the list.

I use Textpad(free) and if opened in that it should keep the formatting correct. It will also view bin files.

It seems I used to use it as a front end for assembling code back in the day too. Nice program

That JimStim and JimStimX Expansion board looks handy.

I ordered one of the expansion board kits. I could have breadboard something, this is compact and labeled and I'll make different db37's for each type ecm/pcm to plug into it.

Funny this topic came back up. Been working on this using the Haltech bench simulator.

That looks nice, pricy too. I didn't see it on their site, how much is it? Does it do the encoded 24x? Ray Hall makes one too but he gets all the money and not sure it does the encoded 24x either.

I can't afford one of these gizmos so I just build a little at a time till I get there My Arduino Nano's just came in today(smaller than your pinky) so this weekend I am going to try to assemble the Ardu-Stim(crank/cam simulator) to work on it

Thanks guys for this topic
I know its old -but gold for me
Ardu-Stim helps a lot for tiny price

Sorry just now seeing this. These are not on their site but they do sell them if you call directly into Haltech and ask for them. They retail for around $600 IIRC. I use this on the Haltech stuff to test with so was an easy re-purpose of a pigtail harness to make it work.

It does have a dedicated 24x/1x trigger pattern for LS1/Gen3 LS. Has a laundry list of other trigger patterns it will generate as well.

This is quite handy as I tuned a pretty high strung NA combo a few years back that peaked power around 8000rpm. It would randomly cut out and misfire up there despite us having the limiter set above 8000rpm. On the simulator and a scope going on one of the ignition outputs it get's really flaky on these PCM's above 7800rpm.

I'm certain it's overloading the processor if I had to guess. So it'd be nice to strip the binary down with all the emissions crap and stuff that a more racey application didn't need to ease the load on the processor.

"So it'd be nice to strip the binary down with all the emissions crap and stuff that a more racey application didn't need to ease the load on the processor."

Did you try disabling all of the trouble codes? I'd expect that to free up some CPU power, but I have no idea how much.

Thanks for the tip about the ECU simulator.
