Gen2 Coyote tuning

[tbl100]

Hi all,

I'm looking to get my engine tuned by a professional tuner and in my search I've gotten a little feedback. Can I get some comments from the Forum users on the recommendations listed below? As usual I'm very appreciative and grateful of all the responses. Thank you. Tim

1. Add a shield between the air filter and the radiator fan to keep the wash from the fan from hitting the air filter. This will cause idle/drivability issues.

2. Remove the vacuum line from the fuel regulator, these setups don’t run vacuum adjusted fuel pressure.

3. Purchase an SCT X4 device for tuning.

For my own info and understanding, how critical is it to have the MAF sensor to the outside of the curved intake tube? Doesn't the sensor sit pretty close to center in the tube anyway?

Thanks you,
Tim

1. Yes. It's also good to keep hot air out of the intake tract.

2. Correct. Needs a steady fuel pressure. Unless you're running a lot of boost, and then it's only mildly helpful.

3. No. I just had mine retuned. They messed around with the SCT for a long time, and never could get it right. Now it's tuned with HPTuners, and it's much better.

4. The current crop of MAF sensors are pretty sensitive to location. Unless you're using an aftermarket generic sensor, follow the placement instructions to the letter. It saves a lot of headaches later on.

I think the MAF sensor needs to be more than 10 inches from the throttle body. Might want to look it up to confirm. I had mine too close in first set up. Lund tuner advised me, after sending a pic of the CAI.
Cannot compare tuners, 3 of my rides have Lund tunes.

hey Tim - have you tried AED up in Cameron Park? https://www.facebook.com/AEDHP/

they've done several FFRs in the area... not cheap, but they're probably your closest experts on the Coyote

Yes, AED had these recommendations.

I went the Lund Racing rout, did the datalogging as requested after I loaded their base tune. I did two sessions of that and uploaded the info. Reloaded the tune last tune for a WOT session form 3k-6k, have yet to perform that one. Well, actually I did just for ****s and giggles, all I can say is that I need no traffic on the streets to do the data log. It pushed me back into the seat I actually was a bit scared of it. I'll keep the updates coming when I perform the WOT.

I considered Lund but the price tag gave me some sticker shock. I'm working with a local tuner here in Chicagoland D-Mark tuning that specializes in Ford. Has done a couple FFR roadsters. For the same price I get tuning with dyno and he is going to build a custom CAI as he has run into some trouble with the spectre stuff failing.

I've asked this question to several people who did a tune..... Did they dyno before and after to determine the performance/outcome improvement? The answer was always no, but from a seat-of-the-pants, they felt it was better. At present, without a tune, with WOT at about ~ 6,000 RPM, the tires sometimes will start to break lose. Don't think I need a tune on my Gen 2. I've read Gen 3 requires a tune, otherwise they don't run worth a darn.
I checked Lund Racing and a local place that does a dyno tuning, both were about $500-$600

Not sure when Lund quoted you but they are now $1200 for a coyote tune (includes tuner). Is $800
If you have your own but unclear what tuners they accept these days. Looks like they moved to HP tuners from Nguage recently. Their coyote swap pricing now says “no SCT”

Your car needs to be road tested for loose bolts, nuts, fittings, wiring, etc, alignment, tire pressure, brakes, etc, before making your wot tuning run.
You also need to feel confident in your car's handling.
I made my pull 2000 to 7000 rpm. My tire pressure was too high and it felt twitchy. Not something you want on these bottle rockets.
Dyno tuning is fine. It saves you from being on the street and in a controlled environment.
Some think this provides a better tune, when actually both tuners use the same information from the ecu.
The road tune might be more accurate due to actual road surface under the tires, wind resistance at speed and real air flow and temps.
Be careful and keep us updated.

I paid the money to Lund and used their tune. Did a couple updates with them. Definitely worth the money from what I can see. Agree that the WOT runs are scary :)

Lund has definitely raised their prices since I first used them several years ago. I've done three tunes with them. Two Gen 2's (one was a buddy's Superformance) and the Gen 3 in my Coupe. They do good work and if you don't have a local tuner that knows these cars, and the crate version specifically, Lund is a good choice in my experience. The Gen 2 doesn't "need" a tune to be driven. It runs quite well on the stock tune. But it runs better on the custom tune. Especially at the lower RPM's. The difference is noticeable and the car is easier to drive. The Gen 3 is totally undriveable without a custom tune. One way or the other, it has to happen. It runs rich, throws codes, goes into limp mode, you name it. After the tune, hang on. Runs great. They will let you reuse a tuner. In my case an nGauge. But it's linked to the PCM in one vehicle.

I don't know how a Spectre CAI would fail. Yes, they will come apart if not properly clamped. Been there done that. But with T-bolt clamps really nothing to fail.

I agree WOT hits on the street can be a little scary. I agree completely the car should be well sorted and the right location chosen. Lund initially said they wanted a WOT in 3rd. I said that wasn't going to happen. The most recent run with my Coupe was WOT in 2nd and the speedo was swinging past 90 when I let up. That Coyote loves to rev. It gave Lund what they needed. I have a specific piece of highway I go to. But not something I'll do any more that absolutely necessary.

BH, let me know how that goes!
