Datalog information on Buschur's Maverick as the tuning/mods continue and dyno talk

[Buschur]

We've been steady on the dyno for about 4 days now. Ford's algorithms are definitely complex and a PITA. This is the most non-consistent platform I've ever worked with, even bone stock, daily repeatable power was up and down by large percentages. This is one of the reasons we've always believed dyno'ing for testing needs to be done on the same day, same dyno and not even removing the vehicle from the dyno between tests. I also don't believe in any type of correction factors. You don't go the track or pull a trailer and use an correction factor, each day delivers different weather conditions and I've always stood by, "It makes what it makes on each day".

Heat is the biggest factor on this platform so far. The truck has a massive amount of sensors, all trying to monitor something, all putting a limit on what can be done. The intercooler sucks, no surprise there and is next on our list. That will free up some horsepower and get the truck more consistent. It always allows for "free" boost and more timing/less fuel. The front cat I'm also going to assume is causing restrictions if for no other reason the temps that are limiting power. I'll get to that below.

You'll also see from the data below that I was 100% correct that our intake works and shielding is a bunch of bullshit.

We are making gains and finding the limits, I don't feel the truck is going to make 300 whp as I had hoped at this point.

We've gotten to a steady, repeatable 265'ish with a nice flat curve.

Here is some data from the truck yesterday on the street.

The run I'm referencing below is with 93 octane, full weight of the vehicle plus some gear I carry, our 3" intake, oil separator/catch can and our 3" cat back exhaust. Both factory cats are in place.

Run was performed on the street brake boosting from a dead stop and running from 0-93 mph.

*Coolant temps at the start of the pull, 183 degrees, end of the run 189 degrees.

*Staring Manifold Charge Ait temp (after the intercooler) was 86 and that climbed to 120 degrees at the end of the pull. That's HORRIBLE. This should be able to be kept to under a 10 degree rise after a good FMIC is added.

*Starting Intake Air Temp (this is at the air filter) was 66 degrees at the start and DOWN TO 54 degrees at the end. This 100% ends the ridiculous "add a heat shield and the stock sealed box is superior" input.

*Last and the biggest "issue" is the Catalyst temp went all the way to 3018 degrees, which is just mind blowing.

The elimination of the cats I'm going to guess is going to help, maybe for no other reason than to eliminate some heat. Most modern cats flow pretty damn good, I just made 565 whp through an aftermarket cat on a 2.0 EVO on pump gas a few weeks back.

Just some interesting data. We are working on some other tuning features at the moment. I want to get this exhaust off to the bender as we've already had pre-orders but want to get some tuning finished for this package and I don't feel this is refined or has all the features I want added just yet.

3018 degrees is above the melting point of steel. I'd guess your temp sensor is misreading.

Also, I read somewhere that the 2.0L ecoboost turbo gets maxed out early. If this is true, how much can you realistically wring out of it? The 265 hp number you cite isn't bad, but I'm unclear on whether this is the result of your hardware mods alone or the mods plus the tuning you are attempting.

That jumped out at me too, I thought that 2,000 degrees was generally considered the ceiling on cats before they started melting.

There are things in the logs that don't jive, like the indicated gear, anytime you are at WOT the log shows the trans skips first gear and it obviously doesn't.

The temp, right or wrong is what's indicated and causing issues. The sensor appears to work correctly the guy helping me with this who tunes a ton of Ford's with HP Tuners, says it's high but not out of realm of what he sees when being pushed.

As far as the power it's making and the "cause" of the power.....anyone who thinks increasing the flow in and out of an engine isn't beneficial knows nothing about modifying cars. Yes, good gains can be had on most stock vehicles with just tuning, no doubt. Then you hit a wall and you have to increase the flow in and out of the engine to make more. Seeing as how the intake gained power pre-tune and now has the full data of intake temps, there is no doubt that it gains power. The exhaust is totally corked up from the factory, there is no doubt it gains power. I wasn't able to do back to back test with the exhaust so I have no numbers but oddly enough, the highest power the truck has made on any given day to this point was 283 whp and that was pre-tune with just the parts on it.

I don't believe the catalyst temp is an actual reading, most likely an inferred/calculated number.

Maybe a step or two colder plugs would bring that down a bit? I'm not sure, just guessing.

Plugs are on order as is a new stock turbo to be sent out and built larger.

It’s interesting to follow along as you develop this platform. Thanks for sharing what you’re seeing w the software.

It is odd that your best numbers were before you tuned, but you have made it clear that making it breathe easier is crucial. The temp issue is weird, too. It will be interesting to see if you can crack those nuts.

I agree, it's a kick to the nuts so far. The parts have proven to be more effective than the tuning, which really blows my mind since after the exhausts was added the computer is pulling the power back.

I'm hoping to find some type of actual issue today.

Dave, does the maverick use factory widebands like the coyotes and other vehicles use?

Yes.
