Sorry to once again hear about the bad new and also for you to know that it could of been avoided if you were to choose a different tuner has to be frustrating. Looks like you already know what you have to do but if I can help you in any way just let me know and I can lend some advice if you want it.

Best of luck to you getting things put back together.

 

Thing must have spooled up like a **** prior to letting loose. What actually broke? Headgasket? Piston? Rod bearing. Very little details including what turbo.

 

I bet you detonation killed that motor to all hell

 

As opposed to what? Flooding the motor with fuel?

 

Did you open up the tuner's map and try to change anything yourself ? CFT is from what I have read a good shop and group of guys.

I am sure they could post his map when he left there if they saved there maps for every car they tune.

 

I have spoken with the tuner, and he stands by his work. He says that he has tuned many Evos, including several with more ignition timing than mine.

My mod list is on my cardomain page here:

The turbo was stock, peak boost was set at and never exceeded 22 psi.

I have no idea what broke first, but when they pulled the head off, I could see a cracked piston and bent-up valves.

CFT came highly-recommended, and there are lots of positive posts on these forums about them. Now I have no idea who to trust.

 

I made absolutely no changes. I have no idea how to make changes. I brought it to the shop today, and ROLO looked at it, agreed it was the one he did, and then said the ignition timing was well within the acceptable range for this car.

 

Your mods:

AEM engine management system
HKS Hi Power turbo-back exhaust
Walbro fuel pump
Precision 880cc injectors
Greddy Profec B Spec II electronic boost controller
Injen intake w/upper intercooler piping
ACT clutch
AMS fuel rail
AEM fuel pressure regulator
Sparco subframe brace

And you put down 330+ on a mustang, No cams/gears? Sound high to me.
Maybe 330+ on a dyno jet, yes.

 

I did not mean you killed your own car. Do you have a wideband to monitor AF? If so what was it reading on WOT?

So what did he say he would do for you? Since he admits it was his map?

 

There is a pic of the dyno graph on the cardomain page.

 

That is where I got your mods from.

 

Did you change any of your setup?

Speed density is dangerous. If you tune on SD and realize you have a boost leak, fix the boost leak, your A/F will be way off (lean enough to crack or melt a piston). It is unlikely that the tuner messed the car up. They tuned a 668whp GT35 evo ProccoEvo here, a stock turbo 460whp on c16 and are working on a NASTY black Evo that will be someone to keep an eye on in upcoming weeks.

 

believe us, that map is seriously fuc*ked.

your fuel map should look smooth and follow the shape of your torque curve.

your timing map should retard as it comes near peak torque, slowly ramping up as you approach redline.

the stock basemap on the aem is much closer to what your maps should look like. the stock basemaps fuel settings are just set too rich.

 

Yes, if you take a look at the map, it's pretty bad. Timing was just a solid square of 17 or so degrees which probably where it killed itself.

 

It doesnt look like it wasnt tuned properly. Hence the flat map. I dont tune DSM's so I cant comment on the excessive ignition timing. 13 degrees from 5,000RPM to 7,700RPM and 9lbs to 21lbs? Also, the vacuum portions of the map are very similar to AEM's startup MAP calibration. Do you have a dyno sheet you can post from the day of the tune? Not pointing fingers. Just point a couple things I noticed out.
