Works like a charm with my Holley setup :D
Of course it does because it's Aftermarket stuff. I like my Holley HP setup on my Cobra as well.:cool:

I can live with a wonky tach at that level for the time being. Ford has it's way and if they can FUBAR it, they will. All I know right now is that it runs and I'm headed to the track this weekend and praying that all my work stays working. I have watched the tach readings with my SCT and it goes wonky in that area as well, but the Coyote gives correct and accurate readings.

I'll update next week. But I will say, I owe a lot to you guys for advice, info and just encouragement. I often criticize sites that "talk the talk" but can't/won't deliver. Having been in this business my entire life, my goal is to help, not hinder progress. So, go out and have a beer on me, I'll figure a way to pay for it. :)

Might try talking with the PBH guys, they know a thing or two about the latest gen CANBUS. They might be able to help you. I'm pretty sure the gen1 control pack doesn't have a CAN output, but for sure the gen2 does.

I've already spoke to them. Yes, they all have CANBUS, but that's not the issue. I do have my tach working, just not smooth in the range mentioned. Again, not a big deal but would like to get it right. I'm also using the PCM out of the "salvage car" but that's not the issue either. It has to do with signal incompatibility between the two different systems. Again, not a deal breaker. This also may be just an issue with the Gen1. I may try the Ground Loop Noise Indicator, but that may not be a 100% fix either. From what I gather so far, you can have it accurate at a lower scale (say 0-6000) or the upper scale. If set lower, it tends to exaggerate the higher readings. i.e. when actual engine is at 7k, the tach may read 7.5k In my case, I use my shift light which I can set to anything I want and the PCM harness has a dedicated tach analog signal wire which I already have working so I watch the light. :D

Thanks for the beer! :cool: I really admire your perseverance. I took the “easy way out” with the Holley :) As an electrician that plays with turbine controls all day, I’m always eager to follow this type of progress. I just didn’t want to deal with the drive by wire setup. I’ve reached out to a few buddies with similar setups and if they have any actionable intel, I’ll pass it along.

I’m pleased that you’re enjoying your tenure here. This forum had seen a lot of helpful people come and go since 2007 but I’m very happy with the cadre of SN faithful that we have now.

Last shots of the exhaust from underneath. The entire system is higher than before, which gives me a tad bit more ground clearance. Lowest part is the header connection. I like it a lot. Not the prettiest, but who's looking under there anyway. o_O

Removed the bell/ball from existing "X" pipe rear and put the slip sleeve there. A lot more stable!

Side shot on my rack. No more clamps in the way! Picture deceiving, but it's higher than the Full Frame bars.

Track weekend was great! However, there were some issues:

1. Got nabbed for sound on the first session blowing a 103.5db! Guess third gear at 6500 was too much. :eek: Remedied that by shifting sooner and all good. Looking at either another type of Borla (using the S type now) or going to Dynamax Turbo's.
2. Put two wheels off T2 for the first time in six years! Yep, gotta' get used to the power out.
That was just day one and first two sessions!
3. Had a strange one coming out of the carrousel, which drops about 50ft and has a long left hand slightly off camber at the bottom before the straight to T7, the engine all of the sudden had a drop in power for a few seconds. This was weird, but did it again the next lap in the same place. I had 1/2 tank of fuel, but after coming in after the session, topped it off (9 gal.) and said if it goes away, it's fuel starvation due to fuel going all the way to the right of the tank. It was a fuel starvation problem and that was taken care of. I mirrored the same scenario the next day just to be sure. All well, but now have to figure out how to cure that. Of course, normal driving won't do that. :D

Other than that, this thing is a beast! Damn fun to drive and now can actually start out near the rear and catch driver's that I had to give point-by's to. I didn't even push it that hard doing 5-6k range, but when it opens up, OH MY! My buddy's son (pic below) is a pilot and drives damn good. I attribute a lot of their ground hugging to the wing on the back. He takes corners much smoother than me and has no panhard bar to boot!

Other than the fuel issue the car/engine was flawless! No working on it, no dialing in anything, just park and drive. Good to know I have a good mechanic to take care of things. :cool:

Once I get some footage put together I'll add a post here. Next event is Laguna Seca in October.

Nice.

There are a lot of outfits that make baffled fuel tanks. If you're lucky enough to find one (junkyard, ebay, etc) the factory 03/04 fuel tanks had some of the best baffling systems ever seen in a production car. But even if you can't find one, those aftermarket outfits like Aeromotive, Glenn's Performance, and maybe some others have replicated it and actually made it better.

Got a few video's from a couple of track days lately. First is Laguna Seca in my Cobra, which was a scheduled event during my Coyote swap, but well needed to get this on track again after a few years in hiatus. Forgot how much fun this car is on track. The second part is the newly installed Coyote (Gen1) in the Mustang at Sonoma Raceway, which is the reason I was pushing to get it ready for that event. Took a day to learn it's new possibilities but in the end a GREAT change for sure. In my case, I can drive both cars about the same so I stay within my boundries. Still looking into a fuel fix this winter and will have the Mustang at Laguna Seca in October for more fun!

You blew sound at sonoma??? Lol wtf
Yep, at least they said so. Must've been the 3rd gear 7000rpm through T12 (sound area) that caught them. Said I was doing 103.3db. That was with the Borla S Type mufflers and a stock "X" pipe (no cats) and BBK LT's. I just short shifted the rest of the day prior to that. Think it cost me a second overall, but not too bad considering this was the first outing with the Coyote.

Back from the weekend at Laguna Seca with SpeedSF. Good times. Sat. weather was wet for the first couple of hours, then sun in the afternoon. Sun. was dry and sun out about the same time. Lots of very fast cars/drivers. I had a McLaren and several Radical's in my group. wth! Rice rockets galor!!

Had them do a sound check for me on Sunday and blew a whopping 88.6db, which made me happy. Now I feel good about doing 90db days there. Times started in the 1:57 range and I worked down to mid 1:53's, which I'm good with for now. I need to do some pedal work for my feet. They are atrocious at best. Clutch pedal too high so doing mods to fix that and the throttle (with the bracket for the FBW pedal) just brings it out to far for my braking style so that will be addressed this winter. Also, the dreaded fuel starvation under 1/2 tank is there. It was fun the last session as I took a risk to see what would happen there and it showed up several times, T2, T5, T6 and T11. Wow! I'm going to try the Holley Hydramat.

For Frank.JD.Perez, times at Sonoma were in the 2:07 range and for me and first time out with the new setup, very pleased.

Thats how i felt the first time there (86.4 or something) then i swapped my motor and that was out of the question. 103 days only for me. Also the atmosphere and time of day effects the db levels

Not bad for sonoma nor laguna
