I actually spent Saturday afternoon doing what you are talking about. I first worked on making it idle properly with one mapped point, which turns out 15/0 seemed perfect and it needed only around...

I tried a bunch of things today, none of it really worked out. What seems to run the most consistent and smoothest is running purely mapped point 14 for idle & part throttle, and it still seems like...

Alight, I've had some time to look at this now. The stock fuel economy & drivability distance tables are set up 1-10, which are mapped points 1-7, 20, 21, & 14 on the fuel economy mapped points...

Edit: I'm comparing the 0+ spark tables with the 14+ spark tables, and I see that they are in fact more aggressive, especially in lower loads. Is running too much timing an issue if there isn't any...

Ahhhhhh I see what you are saying now by getting ahead. I'll try making some tweaks this week.



I've screwed up before had the PCM averaging a ton of MP's and I didn't know why it was...

That's really what it feels like, some sort of misfire. But I'm not getting any error codes or MIL light either... I'll try it through.

I didn't catch that, but I see it now. Thanks!

The stumbling is definitely happening even in just the pure fuel economy tables with heavily retarded intake/exhaust cam phasing. I've changed mapped points and distance tables and never got it...

Interesting. I may need to play with it and see how much if any I can retard the cams and still have good drivability. Maybe 0/0 isn't the best answer, but leaving the stock cam phasing even when...

So running 0/0 without any IMRCs surely makes for a smooth ride but throttle response is kind of blah, most likely due to the less efficient combustion and most likely lower cylinder pressures. The...

I mean, the numbers look better on this run for sure. More spark advance, more air flow, more fuel flow. It HAS to be making more power on this run than the previous logs. I wonder if maybe you...

On that run you went to .74-.75 lambda in third gear for some reason. Maybe o2 sensor protection, or cat over temp? I can imagine .74 makes a lot less power than .84. The truck manifold just looks...

You have up to 4 degrees of knock retard, but the one thing that jumps out at me is the low MAP from 3500-7000. Something is definitely creating a restriction on airflow. Air filter, air intake,...

I read some papers last night on this and it's pretty clear. Decipha is in fact correct, and you are correct as well. At the end of the day though, people want to know how to tune their car to...

I don't honestly, but I might have missed something. I see where you added spark now, that actually makes more sense than putting it in the borderline tables.

It looks like your OP cam angles are different from stock, at least compared to my Gen 2 controls pack settings. Did you tune these on a dyno?

Your spark tables look untouched. How much advance...

I'm trying to figure out which mapped points are causing the stumble / surge at low rpm & load with IMRC's removed, so I figured I'd try each mapped point individually to see which one(s) are causing...

No, the IMRC valves are physically locked out. The ?intake manifold runner sensor? voltage is the data log is showing 4.98v but I have no IMRC valves or none of the pigtails connected to anything....

If you figure all the man hours you spend tuning your own car, especially if it's a new platform, you'd be way better off financially paying $1000 for a tune. That said, there's satisfaction in...

I definitely didn't change those. Any suggestions for what I should set those for?

IMRC Sensor voltage is a constant 4.98v in my data log. I don't quite follow what the "offset" voltage or...

Maybe I complicated this a bit, I went back to square one and tried something very simple.

I didn't touch the distance or mapped points tables, spark tables, torque tables, etc and I left the IMRC...

So the equivalence ratio lambda commanded is always about .06-.07 higher than the equivalence ratio lamba at the WB sensors on both banks, at idle, cruise, and WOT. I have a third AEM sensor as well...

I got the PCM pin-out from Ford and cross checked all of the wiring and the only issue I see is the PCM not giving the correct +12v and ground to the starter relay when it receives a start request. ...

Thanks, I think I got it mostly figured out, I just need to bolt the '18 manifold back on go test again. I literally did the opposite of what I should've done on a couple tables and switches.

Thanks for the honest response and good information. I can definitely tell you guys have reversed engineered a lot to get where you are, I just need more time to dig around. I just bought and read...
