I know you will get that WOT lined out then I want to see some video. Turbo V-8's are awesome. My son has a 5.3 LS and an 88mm turbo going into an old 1976 Skylark SR and I can't wait to see what that is going to do. It will be a year before he gets that far so I will be following your progress and enthusiasm! :thumb:
 
Thank you. I am currently tuning it on the factory ECU as I need a proper engine wiring harness built for my AEM ECU. The Ford Copperhead ECU is no joke tuning haha. Has like 14+ spark timing tables and a whole plethora of stuff waiting for you to screw up. Makes the DSM ECU seem like a lego toy in comparison. It's running great part throttle and idle...now dialing in the WOT. I have it on gate...3psi on pump gas so I have a little margin of error. as I figure it out


100% facts here. I have a similarly powerful ECU in the edge, and honestly I didn't even bother trying to learn it. I just paid a company for their tune and went. The amount of maps, inputs, and formulas it uses are straight ridiculous. Honestly if you could create an easy to use interface that would do all of it for you, you could make an absolutely KILLER standalone out of it to sell to other platforms. It's insane. The SD alone is an absolute marvel of engineering, and the fuel maps that auto adjust based on the slightest of inputs combats knock like a champ. The Edge practically tunes itself for whatever fuel it's running and whatever conditions are outside.
 
Just want to update this. So, I have been tuning the Mustang on the stock ECU but I parked it about a couple months ago because it has some smoking going on during idle and decel so I will be doing the valve stem seals. Yes, I have been kicking myself everyday for not doing that when the heads were off when I did the valvesprings. Otherwise, car was running real good and was right around 700rwhp'ish per the Dragy run I did. I had it tuned on an E30 blend and 10-11psi boost max because I was maxxed on the 52lb/hr injectors that I borrowed from my truck. The FIC 2150ccs are back in it though (needed serviced) and they are dialed so whenever I get it back together (valvestem seals on this is quite the job, front cover has to come off and so do all the cams etc) I will tune it on E85 and turn the boost up. Should be nasty. Just dragging my feet on it at the moment taking it apart LOL. I also put Magnaflow streets on it because it was just too freaking loud and popping and gargling everywhere with the Roush axleback mufflers I had before. My neighbors also don't have to kill me during those cold start idles.

I know it's Feb. The cold and just being a lazy ass, I haven't finished this or even started LOL. I do have everything taken apart though. Viton valve stem seals were ordered and I just need to find some idle time to get them installed. i will need to replace my O2 sensors (factory widebands) and most likely, reinstall them at the stock locations. They were in the downpipe instead of the headers. Track is opening soon so need to get on it.
 
Been driving the car for about a week or so. Seals didn't fix the smoking issue so I am going to guess it's the guides in that 1 cylinder that are the problem. Been tuning it on full E85 and been making rips here and there. Will have it on the dyno to see where it's at on LOW (11psi) boost. Seen some low 7s so far in the 60-130 gingerly shifting it. Pic from a few days ago below....and a quick hit in 3rd. No traction of course LOL.

Just crazy.
 
How do you like that TruBoostX? I know it's a waste of money since my gauges all work fine, but I 100% want to swap my old AEM digital gauges, for all AEM X gauges. TruBoost X, X-series wideband, and etc.
 
Love it. It actually belongs to my Galant. I will be getting one from Sirch Labs most likely for the Mustang. https://sirhclabs.com/

I had planned to run AEM standalone to control everything but I have abandoned that idea....and may just have to work with the stock ECU and associated piggybacks for now.

I had the Mustang on the dyno last week. It put down 625rwhp without revving past 6k rpm because of some issue I had in the tune that is now rectified. That's on wastegate 11psi. It can rev to 8k rpm now. :D

BTW...keep in mind AEM was bought out by Holley. If your old gauges work...just hang onto them. I still have a very old AEM wideband in the Galant that works. I am glad the Coyotes use widebands stock so that's an unnecessary purchase for me.

Had it on the dyno last week for some preliminary pulls. On wastegate (10.x psi) and on a medium boost (14-15psi) pull (which was only pulled to 6k rpm) because of some issues with the tune. Still a good place to start.
