[quote="Madhatter"

You think you can cycle each output? simple on/off to test the coils and injector drivers? That's all the ECU does on my end, all i can do is turn them on/off to test the function of the circuit and component. Really helps in tracking issues.[/quote]

Forgot this part.

Yes, I should be able to do that if I write a test program which I'll start working on today. The idea is on/off switches for all the drivers and also rpm setting so I can see the tach work, coils fire plugs and such. It shouldn't be too hard...50 lines or so maybe.

Boss, have you the Ferrari Porsche Hunter 312/512 book? It has the owners manual for 512.To Start,,First ,,remove plugs and tow 5 miles in 5th gear.You got way more tune than 1970 512M,think you need a block heater and start @ 180
I got accusump for pre oiler,I need block heater for ideal start conditions,
why no pre oiler on Gemellocattivo?

The goal of this project has always been an engine/car that looks and acts normal...... until the throttle is open.

First start with new engine is always a challenge, its harder when you also have a new ECU and harder yet when you have what I would call "alpha" level at best software in the ECU...and harder yet when I have no time to work on any of it. There is an awful lot to keep an eye on all at once....I just need some time to sort though what I'm seeing. Today I'll pick up some gas and confirm that is the fuel pressure issue and will also work on the ECU driver test software so I can test all the ECU output function and wiring. Then it will be time to fire it up again and see if I can keep it running a little longer next time. Step by step.......

I've never used pre-oilers. I know some people like them but I've never seen compelling data that syas they help so I just haven't bothered.

I completely hear you, at the very least I have Nick to bounce stuff off of in real time and also for the "here hold this"

moments... But yeah single person projects require a lot more work, so much to balance at once and track.

It was out of gas...fuel in, fuel pressure in 1 sec flat.

I mostly got the test program done....should be finished tomorrow. It lets me run each coil and injector at wjatever rmp with whatever dwell or pusle width. I'll add the tach and fan and fuel punp and any other outputs i have too.

Its going to be COLD this weekend so next run attempt will probably be tuesday, so i want everything tested before then

Thank You Ingenere,
I got Married In buffalony Jan 1977 when there was a bad blizzard,I had 2 heat lamps and took the battery inside @ night.No way my 2600 Sprint would start @ 20F,learned that in 76 and 75.Got down to Austin because I had a long extension cord.
My experience dragging 330 mandated a 2qt accusump where the battery was,battery now where spare tire was..Quit that after running down kawa 900 1100,,
OOzz that 2qts and those 2 cam never rattled,much quieter
I fitted a 3qt sitting where accumulator was and secured where coils were but its tight fit.
51857 is coming along,pics soon ,,
In the end its who Can Put There Foot Down
I never crashed,never been passed,reggazz wants a test drive
will have ck book

The test program looks pretty good I think. I can add more to it if need be but it will test all the important stuff....I'll try to find time this weekend to try it.

Perfect!

Now you'll get to check that each component is wired and assigned correctly... or not

J/K

It's a very useful tool though, I like that you have control over the time function, most ECU's don't give that level, it's simply on/off. If you wanted to get real nuts, you could now bench test each coil for optimum dwell time over voltage and set accordingly. More work I know... screw it, just get it running!!!

I'm using the front-end programming so short times times will be a little sketchy, no interrupts. The ECU has to run the loop and get back to it. I think with a short program like this I'll have about 1-2msec resolution which is fine for wiring testing but scoping the ouptputs would show they don't match the input times very well. The other option is put leads on a couple digital input pins and atach a crank signal generator (which I have) then the real code could run but I'd need to put all these switches into the real code.

The coils are GM (copies) so I assumed GM optimized the dwell time and copied the times from them.

Aghhh....I'm running a beta version of ELconsole and it supports stuff that the FW doesn't yet...like access to the coil outpus from the main code so I couldn't load the test program into the ECU.

OK then.....I guess I'll do it the hard(er) way and add the switches to the real code. Not sure I'll have time to do that over the weekend though

I loaded the test program with no coil stuff and it worked nicely. I heard all the injectors clicking although since they are buried in the V I honestly couldn't be certain which one was clicking. The tach is working, but is reading about 300rpm low so I'll add a tach calibration feature to the code to fix that. The cooling fan is not working, but I don't think I finished wiring that, I'll need to investigate.

The coils I'll re-test with the engine cranking I guess.

Stethoscope... or even a long screwdriver with the handle in your ear.
