Wondering why my ignition tune page shows 3 degrees but the gauge page shows -4. Any ideas or am I making myself look like a fool!

 

Check your compensation maps.

It looks like your air temp is sitting at 50 degrees C . Maybe you are pulling 7 degrees due to that ?

 

Nope. Not air intake compensation. Gauge page unfortunately does not tell you what is being compensated.

 

So I did data log and watching the ecu data the raw ignition value is 3 degrees yet it still idles at -5 on the gauge page. Also the injector volts inj3 flashes 0volts to 16v approx. Data logging the inj3 volts do not fluctuate.

are you using target idle ? , I see your idling at 1250 rpm, and your target is 881rpm . One way to lower Idle is to pull timing.

Maybe ecu is pulling timing to meet your target idle ? , set your target idle to 1200 RPM , see what happens.

 

Cant you go to the Calculation trace under "Help/Documentation", then select the Ignition Trim tab, shows you what values it uses to get the final ignition number.

 

Yes your right. I forgot I read that in the manual. Wil check when I have time. Thanks.

 

So I finally got to try the calculation trace. It is showing me that I have ignition trim up to 10 degrees due to knock trim. The knock value never moves from 1 that I can see. Holding the idle at 3000rpm it does not trim.

Is there a way to remove this knock trim. It is the stock knock sensor only.

 

I may be incorrect, but I thought the only time the ECU would trim ignition due to a knock reading would be if it was in closed loop ignition mode. I'd check that first.

Also can you post a pic of what your settings are in the closed loop idle control part of the idle tab? If you have the "Use Ignition Timing for P and D" box checked the ECU will alter the ignition timing from the timing map to attempt to hit the target idle speed set for each water temperature in the table.

Appears you were right. I compared my map when I dropped it off to the tuner and after. Wondered why it wasn't doing that before and why the car sounded different during idle.

 

So was it the Use Ignition Timing for P and D or the Closed Loop Ignition Setting being enabled?

 

I have not physically tried it yet. Once I have time in a few weeks I will try removing closed loop ignition correction p&id control.

 

Selecting or deselecting this did not resolve. Here are a few pictures. Car does not idle or free rev smooth.

 

.

 

Try changing the proportional gain, integral gain, and differential gain settings all to 0 and leaving the box unchecked. Regardless of whether the box there is checked the ECU will be in closed loop mode and will alter the timing to attempt to hit the target idle value if any of those fields have non-zero numbers in there.

Also were you able to confirm as to if your ignition was set to open or closed loop mode? I'm still curious as to where that knock trim is coming from...

I really wonder why I didn't notice it before when I had the base map from adaptonic running the car aka prior to dropping off at the tuners. Also why under trace the signal looks like it's taking this from the knock sensor yet the knock values are not changing. Might just send an email with the file and a data log and see what input they have. Will not be touching the car for another two weeks. Time is hard to get nowadays.

Appreciate your input

 

Send me the actual ecu file if you don't mind, I'd like to fiddle with it. Also, I'm PMing you the email of Mark Gool. He's an adaptronic tech that has been answering my questions for a very long time. I've actually got an email chain a mile long with the guy.

He can probably run your ecu file on the bench and tell you exactly what is happening.

 

I sent an email to Mark. Skeese what is your email?
Thanks,

 

Well it was the ignition ramp setting was to high and the fact it didn't seem to matter if I had the use ignition timing for P&D setting check or not. Changing the values to 0 worked.

Also checked the new eugene software. Coming a long way.

 

sethallen.cca@gmail.com! Shoot my anything you have still and I'll gladly look at it.

Did you end up working though it with Mark? He's a really helpful guy.
And that makes sense. The ignition ramp rate being to high can cause ignition hunting at idle. I found this exert directly on the adaptronic site:

"Assuming it’s not a rich-lean hunt, we need to find out if it’s an idle hunt or an ignition hunt. You can now unlock the ignition timing and re-enable closed loop idle control with ignition timing. Normally if this is the problem, you can tell because the ignition timing will jump back and forward really quickly and the hunting will be really fast. If this is the case, then reduce the ignition ramp rate until it stabilizes."

I like Eugene, but I wish there was a manual on operating it. For me it is frustrating to navigate and get it to do what I want. I'm sure it will turn out great though.

Yes Mark helped me out and responds pretty quick to my petty questions. Eugene software and the standalone datalog software will always improve Im sure.

Thanks for all of the help.
