The harness connector at the '95 end of the conversion harness is both more convenient and Blackstealth has very nicely numbered the pins. Do you happen to know what pin 52 converts to at that end?Quote:

Also both the normal temps and the "scaled" temps are incorrect. Thanks to Aaron for helping me figure that out. The 2.9 file I gave to Greg has the corrected formulas.
Marc, one more thing for you to test.
Open up EVOScan 2.9 and while the purge is clicking, tell me if your idle position switch is on or off.
Good thought Greg.
Just a hunch. The test for the solenoid specifically says the elec load should be off.Quote:

You're seeing a lot of airflow at idle and this is why it's not turning off the solenoid at idle like it should.Quote:

If you scroll down to the bottom, you'll find this now:

What's happening is the purge is never getting switched off as the airflow HZ count never dips down below the deactivation HZ trigger value. Raise this value to say 60 or 65 and set the Activation value to say 100 and flash to your ECU.
Yes, in the photo you can see there's more to it, but I'll create another separate disassembly thread later about the purge and vent systems as soon as I verify a few more things.
I tested this in my car (engine warm, no headlights on or anything) by bumping up the idle till the MAF HZ value never would dip below 50. Sure enough, the solenoid would turn on, but never turn off. Course, I had to verify this by leaving my hood popped and touching the solenoid because I can't hear it. :lol:
The reason my solenoid clicked before with the lights/AC/radio on before was because I have my target idle bumped up to 850rpm. With the AC on, the car idles even higher. Higher idle = more airflow counted by the MAF. This Count put the idle count just above the deactivation HZ trigger so I set this value to 65 on my car and it functions normally.
Anyway, it would seem there's really nothing wrong at all here. :) Just the conditions of the setup on the car need a tweak. Hopefully Marc can duplicate my results!
Awesome!
Holy Crap Greg! I am glad to see this put to rest!
In Chrome 1.1 - All previous code changes back to stock and peripheries as stock I assume. Still taking care of stuff at home, but I'll upload and run test before morning.Quote:

Go ahead and disable bit 13 & 14 in periphery 2 to keep your CEL off.
New software installed - Activation 100 - deactivation 62; The f**king thing still starts ticking after about 5 min of warmup
For the sake of completeness - pin 52 stays low when clicking; Idle switch shows 0 in datalog and airflow is 56Hz.
Had a feeling you'd say that... :( There's also a timer function which activates the solenoid. I didn't run my car long enough to see if it turned back on.
I'll pick this up again tonight.
BTW, have you driven you car yet?
Not since this most recent update, but I did the day before yesterday when it was hot. I'll be away from the car for the next 10 days. Sorry.
Can you explain more about this timer function?
I will when I understand it better
I'm back. Any progress?
Yes. Quite a bit actually. I'll post up later this weekend.Quote:

Got it!
I'm up in Easton flash tuning a couple cars, diagnosing the NLTS issue on Aaron's car, getting new tires for my car and entertaining a date with a hot chick.
Get back to you on Monday! Got a much better understanding of what's going on now. Will explain later.
Did we resolve this issue?
No but I've been working with Marc on it. Made some progress this week. I'm writing something up for him to try right now actually.Quote:

Oh speaking of, remember that timer I mentioned earlier? I believe It's actually a function based off the change in speed. I'm pretty certain the purge activates if your speed does t change for a long period of time. Like when you're cruising for a long time or just idling in traffic and not moving.
timer huh? that seems like it could be used for other coding tricks.:)
No, this is specifically for the speedo. ...unfortunately....Quote:

Unlikely since once the car is at operating temp - if you turn it off and then restart the solenoid will start clicking within just a few seconds of startup.Quote:

The purge valve started clicking as soon as car was warm, but after another few minutes it stopped - after about a minute its back on....
does anyone have a diagram on which pin is what on the map?
for the people adding them
