That's literally all he said. I have no idea...

So, Jon Lund Sr. looked at the logs I sent in and here's what he had to say... "Log review looks good. AFR matured at 9.8 Stoich which is e10 Pump gas. 9-10% ethanol learned. Thanks" The end...

Well, I have a ticket in at Lund to have a tuner look at my logs. But, according to my butt dyno it has picked up some in the middle to upper middle RPM range. I can't tell much difference below ~3k, but power comes on fast above 3500.

But it fits, and it runs. Took a couple of data logs and I'll send them to Lund tomorrow. Took about an hour to swap.

I just meant it seemed different than the F150 intakes pictured in this thread.

I guess it seems taller? Maybe? And the clips are different on the drivers side runners...

My intake appears a bit different than the ones on here however...

Got my F150 intake today from Athens. Tapped the MAP sensor hole to 1/2-20 and used an o-ring plug. Lund is going to look at some data logs when I get them and see if they need to tweak anything. May try to swap it tonight, but not sure yet.

.csv files are the most common. You can open those in Excel. If it won't upload here, you can PM me and I'll give you my e-mail. You could also try zipping it up and uploading it too. Also, if you can include a few seconds of just normal 55 or so cruising that would be helpful as well.

Thanks, that's good to know.

You should be able to pull lambda from the ECM using the SCT. I know my car has always been tuned since the first week I had it and it's always read 14.5-15 AFR at idle and bounces a little. I assumed that Ford used 14.7 stoich, that may have changed. Lambda has always been very close to 1...

This is gonna be difficult to explain and I'll probably mess it up, but... The stoich point of a fuel and the AFR the computer is set to target are two different things. It's easier to think of it in Lambda, where you are always trying to target 1. It takes more E10 (per volume of air) to...

If the car is running good and the AFR is 14.5-15 at idle on 91-93 pump gasoline, it should be fine. I always go by the AFR reading in the information display in the dash, it actually reads somewhat correctly with E85 as well. The readings from aftermarket tuners (IE nGauge, perhaps SCT) isn't...

Not sure how you would verify AFR without a stand-alone O2 gauge. The other possibility is that the sensor is lying and the engine is actually running lean.

Don't know if any of this helps, but here's what John at Lund Racing told me about idle and WOT AFR for their cals. "Pump gas: Stoich = 14.6-14.7 Idle should match Stoich = 14.6-14.7 * and at WOT is should be *WOT= 12.3-12.5" Also, I watch my boost/vacuum gauge on my car all the time and...

Looks like we will be getting a Gates RPM belt in February. I followed Gates on their FB page, GatesAuto. Chad said they announce new products there when they are released. I also found out that my tensioner had some unusual movement in it. It seemed to want to twist under load and shift...

I talked to Chad at Gates today. It seems they're willing to make an RPM belt for our Mustangs. Quote: "We can definitely get a K060675RPM belt set up though. It should be ready for a February release." I'll let you guys know as I find out more info...

Here's a link to the RPM belt PDF... Link

So, I am replacing my OE Motorcraft belt after 15k miles. It's starting to develop a chirp. Gonna check pulley alignment and bearings this weekend. But, I was curious about a couple of belts from Gates. It's their RPM series belts. Problem is they don't have a direct cross from the K060675...
