Read on the other forum another Speed6 engine has blown. He had the new PROcede EMS installed for a dyno tune session. They removed it after a few dyno runs. He was driving home shifted from 4th before he got it into 5th BooM!

depends on alot of things. how much boost was he running, what modifications did he have, who tuned the ProCEDE, how aggressive was the tune on the ProCEDE, blah blah blah.

first, i love the color of your car.
Next, I PRAY the tuner fully discharged/reset the ECU after he took off the piggyback. If he didnt, there is your answer.

Poll: Who blames the car? Who blames the mods?
you live down the street from me (we've talked). we'll have to meet sometime when i'm big turbo.
on another note: story sounds fishy. i'm with Ken. depends on the tune, load and driving conditions... etc.
Before anyone starts speculating without reading the post, here is the Reader's Digest version:
The car was a 2006, built in January 2006. The car was tuned using a piggyback system. It was a very conservative tune at stock boost levels. The car performed 3 dyno pulls, then a road test. The piggy back was removed AND all power was removed to the ECU to clear fuel trims. The stock ECU was then plugged back in. The car was then driven hard a while, then went on a 150 mile road trip. The engine popped while accelerating to pass someone. There were atleast 200 miles between the Piggyback was removed, and the engine blew.
No answer has been given yet, and anything anybody says is pure speculation. Wait a week or two for when someone can put facts to this case before spreading any false information.

Sad thing is we will never no what the cause was! But this sure does hurt them to bring this to market even if the EMS was not installed on the car when it blew! The damage is all ready done in the consumers mind!

I live down the street from you? You're in OK, correct? I'm in Plano, TX.

I doubt the ems had aything to do with the failure. It's mor than likely just a bad rod/bolt just like all the other failures...It seems like if you have an early 06 your on borrowed time..
I'm driving a speed built in 12/05, I hope my engine lasts until my built motor gets here, but I wouldn't be suprised if it didn't..

i swear i have read that 3-4 of the blown engines had tuning and then it was removed within days of the engine blowing. i think the ecu reacts weird to removing the tuning system. something has to be off. maybe it runs lean after the tuning is off or something

As far as the engine blowing by her self is a bit unusual. Always we have to do something to force the engine to blow. Mazda engineers are beyond more knowledgeable than us. They are spending huge amounts of money and countless hours to develop an engine that we call bad engine or not strong enough or whatever else. The same engine is used by Mazda's CX-7, Speed3,
Lexus and Acura. 2.3L DISI. Used in hundreds of thousand of cars. Amazingly engineered with world award in design. I would say to all of us to be very careful when it comes to modifications and revisions to the engines management. (angel)

the ecu goes back to the way it is from the factory when the EMS is removed. so it has to learn all over again. if you remove the EMS then go out and drive your car the way you did with the EMS tuned and attached, you are setting yourself up for disaster.

so youre saying the same would hold true if you simply disconnected the battery on a completely stock vehicle?

Obviously hes not stock. He was running it hard. Speed6 from the factory is built for aggressive driving. It his is own fault. I have no pity should have been more careful

I'm not very familiar with the Procede unit, so I couldn't jump to blaming it as the cause of this, could be lots of things, but here's some good reading regarding piggyback systems.
Again, not blaming the procede, just thought this might be informative to someone

I can't believe I read that drivel. Your dude Eric here is not so smart. Maybe he was just venting because he had bad luck (more likely bad understanding of tuning) with a piggyback or trying to relate to the morons who read his stuff regularly? He left out the fact that when you "floor it" the ECU soon switches off the O2 feedback (closed loop) for AFR and runs from the MAF/MAP through "look-up table" maps (open loop) for fuel, timing, etc. WTF is "enlean" anyway? Eric is an illiterate "f'in'" moron... If he works for Cosworth, I'm sure it is in a low-level position. Maybe an "apprentice" trying to actually learn something? Maybe as a floor sweeper? AFAIK, Cosworth doesn't manufature or tune street OBD2 engines...
Piggybacks work very well for what they're designed to do. There are obvious limitations and some ECU functions they can't control, but Eric is off-base with his diatribe.
The piggyback hardware/software doesn't "cause" engine failures. The failures result from unskilled or ignorant "tuners" and drivers.
Happy Motoring!

Hey, I'm not even going to pretend to know the technical stuff on how any of this works, you def. got me beat there!!! And yes, you can't believe everything you read online. But I know this guy, and he has a proven reputation to back up what he says. I however do not know you (personally I mean). Oh, and he does product R&D for Cosworth.
Heres an article that might let you know who he is

But I agree you are 100% correct, the issue is more likely a bad tune and/or driver.
