LR 2.4 HTA 3586 on E85
Not boost. Fuel cut load x2. It's a v7 upgrade. Look at what the load was at the rpm cells. Then input the expected load. That way if the car sees too much load, it cuts full and drops rpm down like the factory fuel cut load. This is one safety parameter. There is also boost error correction table as tscomp mentioned.
I have been talking to one of my tuning buddies here in Florida since this happened.. he told me if a fuel cut x2 was set this would have stopped spike before it had the chance.
He also told me if the boost desired engine load or psi was properly setup right and the boost error correction tables had been properly setup to assist in safety as the main WGDC was raised, the ecu would NEVER be able to spike like that.. it would get auto corrected.
Half the time I have no idea what he is talking about so i figured I would post this here and see what the guru's think(this is why I would never tune a car).
sorry didnt read the 2 posts above mine been a rough night.

If anyone wants to take over this project i will let the car go cheap. I will have the final verdict on Monday on what needs to be done to get it back up and running.
yea sure does owell you live and you learn i guess. I have learned allot cars and builds and everything in general thats for sure. I have also met some really cool people along the way.
I do want to appologize to Scott at ttp I am confident he did tq down the head studs to the proper tq . I did not know that the lifting of the head would change the tq readings. I didnt think the l19 could stretch.
He still had no excuse to charge my cc after the fact without my notification and I was very unhappy with his tune and other things that did happen during this build.
Should have the final verdict of the damage on Monday hopefully it can be put back together and I can enjoy the car for atleast a couple of days.

no amount of boost error correction could have prevented a failure of the wg solenoid. I know as a tuner that mechanical failures happen and it can hurt a motor. Yes in theory you could adjust fuel cut constantly to just above desired boost to have the ecu stop a sudden spike. Since it almost never happens it is very impractical and when tuning a car usually the fuel cut is turned off until the tune is finished. It is quite a time waster to modify extra tables after every pull. Most customers dont want to pay for extra time on the dyno and for the tuner to do it that way. I know I had a car that had the FPR line popped off the intake manifold and it went super lean instantly. Not anyones fault and luckily e85 is very forgiving to a quick problem. I dont think Diirk is responsible for this at all. Sorry to say this but people who mod cars need to accept the fact that cars break when modded.
Really sorry to hear how this ended. You had to have been so excited to get this build started only yo have it end like That. I'm doing a build very much like yours but I had two parties involved during my build, the actual engine builders, which I had then build the entire longblock from vc to oil pan, and the shop/ tuner which will be doing the uninstall and install of my new motor. That way I know where to point the finger if anything goes wrong. God forbid.ha!

Lots of "experts", lots of opinions and to be honest, I'm done reading them. You got my PM's and I told you what I'd do for you on the engine if you decide to send it back here.
Personally, I'd think with what you are going through you'd stop listening to 100 different experts who THINK they know what is going on.
I will say this before I unsubscribe from this train wreck thread. When I tune a car I set the fuel cut higher than it needs to be, I do this because I HATE hitting fuel cut as I am adjusting the boost. I do however have the timing maps set in negative digits in those areas in case I overshoot.

Looks like Dirk blew your engine up. The car was running great until it hit the boost spike. There are ecu parameters that could have prevented this. This is why fuel cut x2 was put in v7. On previous version roms you just had to max out fuel cut after so much power, but V7 has fuel cut x2. If ecu boost "sucks" on high power cars, why did he do it? That makes 0 sense.
I watched the video of the car after it was built and tuned originally. It sounded great and made awesome power for low boost. You probably should have never left and you wouldn't be where you're at.
I went to ttp's website and there are no "new" heads for sale. They don't sell any new heads. It sounds like to assumed the head you bought was a new core based on its looks. I don't know what you paid but I read you traded your head as a core to be rebuilt. This is typical.
If you turned in a USED HEAD then why would you think you would get a brand new head in return?
You do know cylinder heads BARE WITHOUT VALVES from the dealer is $1425, then you add in valves $350, Valve guides $150, Springs and retainers $425, 3-5 angle valve job and valve lapping $450, pressure testing etc.
For comparison, Buschurs ported head is on their site is $1625 + used core and you get a used head from someone that turned theirs in as a core just like you said you did.
It sounds like you are just quick to jump to your own conclusions about everything, your blaming everyone, making accusations and now apologizing for your misinformation in the end.
Your first mistake in everything was thinking that you can make a 700whp street car indestructible and underestimated the responsibility in owning one.
Agreed.

I for one can't stand your stupid quips that are like prodding your finger into a fresh bullet wound... You are a TTP nutswinger... WE GET IT...

Yeah man. His kneejerk reaction may not have been well thought out but after spending thousands of dollars and not getting to enjoy the car you'd be pretty hot as well. He apologized and is looking to move on.
