SD Tune Time

[arthansen]

Well, I had a Nitrous backfire out the intake at the track last night. Toasted the MAF, MAF screen, and air filter. I unplugged the MAF, loaded the SD tune I have been working on, started right up, and drove home.

This kind of forced my hand. I was waiting on 1.6 and the new tuning features to dial in the SD tune but now I guess I will just do it the old way.

Boy, I would really like to have 1.6 sooner rather then later. :

lol bad timing hehe

rofl.. nice..

good thinking though..

The SD tuning is coming along fine except for one area. Idle. It surges and hunts for the idle vey badly. It will die occationally but usually finds the idle after about 10 seconds. The V6 has very little idle control so I am not quite sure how to correct for this. I raised the idle by 150 and this helps the dieing but the surge and hunting are still there. Any ideas?

???

hrmm.. i dunno..

we dont really have an air intake conrtol valve... the DBW TB handels all of that..

so, i am not 100% sure what to do about that one..

hopefully someone at hpt will chime in, i am curoious about this as well..

its good to hear you are making progress art

Add timing (I run 28 at idle), get your trims in line, disable proportional idle.

[Missing2]

are you running 28 degress in the spark table?

or are you seeing 28 when you are scanning..

its a big difference becuase at idle our spark tables get aufully adjusted and skewed by other tables..

[arthansen]

I will try the timing adjustment. The trims should come in line with the SD tune. Where is the control for "Proportional Idle"?

Proprtional Idle should be under the Open/Closed loop fueling. I run 28 degrees at idle in the Base Spark tables (in and out of gear).

"Proprtional Idle" is not a V6 option. Either is In and Out of gear spark control. These are the kind of controls that us V6ers need. We feel like the bastard step child.

That's pretty weak. I wonder if it is coming, or if it cannot be changed...

i think its time you make another feature request art..

[arthansen]

The MAF is back in. Without some idle control, the car will not run properly. Attempt #3 at a SD tune has been aborted.

I wil make a feature request and see what happens.
