Drop into Gear stalls Immediately (Cold Engine)
For changing idle airflow in the editor, go to engine>idle>idle airflow tab> base running airflow (idle airflow). Add or subtract from these values based on how much your idle trims were off, what your engine temp was, and p/n or drive.

P Mack ,When I log my Idle airflow do I hit the space bar to start logging and hit the space bar to stop?I think this is what I do but will it prompt me to save logged session?the help section in HPT doesnt really say?So what I am asking how do I save it for play back? Thanks...Scott

Ok P Mack ,My Idle Adapt(STIT) is running -.6 to -.52 when cold and gradually goes up to 0 when its at 176-182 ect its like +.04 so now what do I want to do?Subtract this number in the given area's?LTIT Gear is at -.17 and LTIT PN is -.32
Thanks Scott
Thanks Scott
To start logging i just click the play button and to stop I hit the stop button. It will hold this in its memory but to save it go to the top and click scan>save data as.
Yes, you add the number to the given area. So if the old value was 10 g/s, you would have 10+(-0.6)+(-.17)=9.23 g/s new value. Also make sure if your data is in g/s, the table is in g/s.
Those numbers aren't that bad if they're in g/s. If they're lb/min then those are pretty big errors.

I just about thru my laptop lol.I lost all the info I was watching.So I will start over again with it in metric...Thanks Thread Starter

How do I read my Base Airflow table?Does it start from -40 that number is good to -4 and so on?So what I mean is do the values go up from there number?If I have a given airflow at say 95 ect does it pertain to 68 ect or the 104 ect catagory? Sorry to be talking in riddles but its hard to explain in typing...Thanks

Ok P Mack I now have Data ,But what sucks is that the engine was at 86 degrees from sitting in my garage even though we hit low 60's I wanted to get the 68 degree column set.But this is what I have in Metric this time.MY LTIT Gear -1.3 G/sec LTIT P/N -2.42 here is temps (ect)as follows 90= -.3,95= -.7,97= -.9,100= -1.7,104= -1.8 106= -2.2,108= -2.6,111= -3.0,120= -4.4,122= -5.0 130= -4.2,135= -4.1,140= -2.1,145= -4.2,150= -3.6,155= -3.6,160= -2.5,165= -1.5,170= -.7,175= .2, 180= .4,185= .3
So there you have it Now I need to know where the ECT cut off are how to put the right numbers in the right places...as post above explains....Thanks

This is just my technique. If I see -1.8g/s for the few seconds I'm at 104*, then I'll use -1.8 for that data point. I don't worry about a range of ECT values or cutoffs or anything. The pcm will interpolate between values on the table so I don't worry about it. As for getting the lower temps, you'll just have to log after the car's been sitting all night. And you probably won't get the whole table done till winter when you can hit those really low temps.
Also are you warming the car up in park or drive? Because you will have to do a log of each to get STITs for park and drive. Either that or keep shifting between park and drive as the car warms up to get a full set of data.

say I am getting -1.8 at 104 so take my number of 20.51-1.8-2.42(LTIT P/N)=16.29 is my new number at 104?yes I did this in park,Now I'll have to do it in gear....Thanks

Yep, that looks right. If you do everything right, next time you warm your car up STIT and LTIT will be very close to zero at all temperatures. Or at least STIT+LTIT should be close to zero. Keep in mind LTIT will stay the same and not learn until a certain temperature (176F I think).

Ok P Mack the IAC is much closer now,How ever I am still having the P/n to Drive Stalling.But I have noticed where I have this problem is when ECT is 100 or lower.In my log in gear 3 times mind you from 80 to 102 ect my IAC is adding up 18.0 G/sec airflow and this is when I cannot put it into gear without it stalling immediately.when it hits 106ish ect it nose dives to what I am commanding it to do.It is only in gear it does this.Is my Iac shot?
Either your idle airflow values for those ects are still too low, your short term fuel trims are maxing out against their limit (which means your airflow values are too low), or your IAC is maxing out. You may have to just add a lot of airflow to the table in that region to even get it to idle long enough to get data. I doubt your IAC is shot unless you can see that it's not moving when you log data. If it's maxing out it will be full open (310 i think) and the rpms will still be too low.

Ok P Mack ,I have made changes accordingly ,Now that I am at so much more IAC do I need to change Desired airflow max it is set at 40.0 and I am exceeding that I need to put it up at 60.0.Also I have changed my IAC Park position because I have exceeded those numbers.is there anything else I need to change?TIA
