has anyone bought this Boost Control Solenoid product from Grimmspeed? If how how long have you been using it and do you have any issues?

I have this car for about 4 years now and it has about 53K miles. I do my maintenance and oil change every 5K miles. I dont race the car nor drift. I work from home and I only use the car when I drop the kids off from school within a 1.5 mile radius and of course on the weekends around town grocery. Pretty normal stuff.
The reason I asked is that my car is still under warranty and for some reason the engine was making a crackling noise on one Saturday morning. Given the fact I was still using it on Friday to pick up the kids from school without any problem. The dealer mechanic said that I need a new engine and my pistons are messed up. I dont understand the reason since prior to that there was no check engine or any signs. So few days so far based on the mechanic's evaluation. There were no signs of abuse to the engine, no computer manipulation or mess around the cam shaft or whatever. I have a few upgrade on the car. Exhaust, intake and Boost Soleniod. So far the mechanic said it is to my favor, so after one week he called me said the warranty is voided and they found a problem as to why the engine is messed is due to the fact of the Boost Solenoid??? It is becoz they have ran out of excuse and couldnt find a problem so they have to find something that doesnt make any sense? I chuckled when he told me that coz he know I wasnt that stupid to believe their findings. So I told him for that small upgrade mitsubishi is not capable to handle that upgrade? And he was just silent. So he told me to contact their corporate office and make an appeal which I will do in few days.. But I was just shock with their lame findings.

 

did you install the grimmspeed ebcs? was it tuned after the installation? who tuned it? because most likely you will lose your case with mitsubishi. almost any aftermarket part that affects engine/boost management will void your engine warranty. this also most likely voided your drivetrain warranty as well.

i know its too late to go back now but for other readers, if you have engine issues, the best thing to do is go revert to stock and then go for warranty service.

 

It's still in debate if Mitsu can read your ecu and see that you have had a tune. So since most mods require a tune, reverting back to stock may not matter anyways. I personally think they don't bother reading the ecu flashes if it is a cheaper warranty repair. But if you are needing a new engine, I think Mitsu will examine your car and ecu with a fine toothed comb.

Sorry to hear OP. Keep us updated. Pretty crazy if you need a new engine. There usually pretty solid unless you dog it all the time and don't keep up with maintenance. It's posts like this that have me second guessing. I'm still 100% stock but really want to mod pretty bad. But because of warranty I am undecided. My car is my DD and my way to and from work/school.

 

My car is always up to maintenance every 5K and always keeping it clean. It is just odd how my engine would go out like that without any signs or check engine that something is wrong. I used to drive fast on my GSX and it was pretty loaded without any engine problems. And now I am just a driving dad dropping and picking up the kids to school after my work. I dont race or punch my car to the limits coz I got kids with me all the time.

So far I opened a case with Mitsu and the mechanic at the dealer told me that he got an email and it was denied. Someone from Mitsu was going to call me, and hopefully he can fully explain the full reason without an BS just because I have a solenoid boost on the car. That doesnt mean that my engine would go out like that all of a sudden. They are making it sound that the EVOs are not capable for an upgrade otherwise the engine will go out. It doesnt make any sense.

 

Was it tuned after the install of the Exhaust, intake and Boost Soleniod?

 

A Grimmspeed 3 port boost controller REQUIRES the ECU to be tuned to suit your turbo.

If you just whacked it on there without getting it tuned then the engine probably blew up because you were making too much boost. Do you have a boost gauge? What does it normally boost to?

Sorry to hear about your problems.

 

57k miles on my car, I've had the Grimspeed 3-port installed since about 9k miles. You did require an immediate retune once you installed it though! Sounds to me like you caused this by not retuning the engine; you were probably massively over-boosting every time you got on the gas and God knows where your AFR's were due to intake & exhaust in conjunction with the elevated boost levels.

 

I'm leaning towards this as well. At first I was like WTF? But I realized the OP made no mention of a tune with his mods. I'm a newb to modding myself but even I knew that was a big no no. For the most part I wouldn't really install anything without a tune to go with it.

 

Sorry op, but if you installed the 3 port without a tune you were asking for your engine to blow up and you have no one to blame but yourself. If you did get a tune it is generally assumed you have voided your warranty.

 

I did have it tuned after it was installed. I only boost it around 15-20 psi since I only use it to drop off the kids within a 1.5 mile radius. Other than that the car is pretty much stuck on my garage.
I just got an update from the mechanic he said one of the piston was shattered which caused the engine problem.

 

than they did not void ur warranty just because of the 3port, you had the car tuned and obviously they're not stupid they checked the ecu. sorry op but u should of went to stock map, and stock parts before taking it in, my o2.

 

Well the dealer mechanic said that the ECU was clear and no issues there. Went I went there last Monday to check on the car the other mechanic said he really cant explain what happened to the pistons. ECU check was fine, maintenance schedule was fine, the rest of the mods where fine, he cant really tell what the major cause of the piston to shatter like that which he said is very unlikely just for that 3port upgrade reason. But I guess they have to blame it on something..

 

that pretty much sums up everything you need to know

 

...uh, who did the tune?

Tuning a 3 port is not easy. Sounds like your tuner blew your engine up for you. No wideband gauge and doing a tune on a 3 port w/all the bolt on mods??! You probably detonated really, really bad, and shattered that piston. Or, if your ECU was stock and you hooked up a 3 port, BOOM!

 

if you don't mind me asking whats the purpose of the 3port and how good is it for the evo x sst.
