man, I need to learn about the internal workings of these engines better. How does a bent rod hit the oil pump? And if the rod bent, isn't the damage already done? What caused the rod to bend, too much boost, to lean?

whatever the case this sucks.

Also, does installing the Boost control override the ECU safety functions?

 

detonation will do it , too much boost on cheap gas ...

yes the ebc overides the ecu , but the ebc has safety fucntions it self but if it was not installed correctly or not working properly then anything can happen.

 

Does a DME with tuning and a separate EBC have less ability to protect the motor as compared to just the DME with integrated boost, timing and fuel control????????

Second question: does the 'protection' depend on how the DME flash/programming is designed? Do different tunes have different methods of retaining or creating protection?

 

Correct me if I'm wrong, but the EBC's safety functions are tied to overboost only, right? The EBC has no access to any of the other OBDII sensors (can't react to knock, AFR, misfire, etc.)

The stock ECU has more "triggers" that will cause it to cut boost and it also has more defenses in it's arsenal. For example, if you're not already overdriving your injectors, it can open them wide and dump fuel into the cylinders to prevent a lean situation.

 

I had the stock ecu and also had a bent rod,damaged oil pump,damaged cylinder and piston and melted exhaust valve because the clever guys from Upsolute managed the raise the parameters for knock detection so high the stock ecu didn't detect knock anymore.
I sended the Upsolute file to 2 different tuners so they could check the file and they never saw such a miserable tuning,they couldn't believe they were still in business.Repair costed me 13000 euro's
I also sended a mail to upsolute but they never answered me again...

 

See bold above.

 

Ok, I know that there are many questions in here, but instead of doing a full engine rebuild, is going to stronger rods, arp studs and better head gasket good enough to save an engine suffering from these issues(bad fuel, lean, boosting, etc.)?

 

I suspect that 'building the engine' will make it stronger and increase the 'safe operating envelope' in terms of max power AND ability to tolerate 'errors'. But nothing is impervious to all faults.

I thank Tony for his reply above ^^^.

Ard, thanks for the link, that was excellent.

seal gray and ard , tony awnsered your questions. the dme will alway offer more safety , but as long as your not boost happy and have common knowledge on how much with what kind of fuel you will be ok .. if the greddy gets hooked up wrong then thats on you.

951 yes thats enough to to strengthen the motor for protection. but let gets real you still wont be able to run 1.8 bars or anything crazy like that ..

 

you mean because we're split case dependent....I was just thinking about current pressures and keeping things together for the occasional overboost, bad gas, etc.

 

yeah that should be good enough . im getting readt to build mine for the sole purpose of peice of mind...but somethig tells me when its open i may change my mind on somethings... maybe headporting....O ring the heads, maybe sleeves lol who knows.

 

Well the majority of the labor is already there so you might as well.

 

Ok now you stop it LOL.... thats what i have been telling my self also.. but im also remodeling a second house lol ...
