Anyone of you guys dealt with these people?
they screwed up my 63 and they don't want to pay me for for their tune did!!!

I am going to sue them. When they did my tune, they said it has 12 months guarantee. 2 pistons fried after 5 days. Now they are running away from it.

Any advice?

I have heard that they do pretty good job at fabrication. If I just blew my engine I would have contacted the shop first. If I started a thread about blowing up an engine I wouldn't get offline right away. I know there will be tons of question to be answered.

Wow,very sorry to hear about that man.
Any specific tune were they using?

Do you have the 12 month guarantee in writing? If so, and you can prove it was infact the tune that fried the pistons then you have a solid case against FMU.

FMU should chime in to say what went wrong.

Im sorry to hear this man, dont let it slip away, definitely take action and make sure they pay for the needed repair.

GHAZAN

these tuners are trying to squeeze out every drop of hp like you did as a kid measuring inches on your d!ck ... another tuning failure added to the relegation list. Good luck to the OP.

OE Tuning
FMU

loungn14

wow, sorry to hear that. How did you find it it was tune related and not due to hardware?

BenzoBoi

Sorry to hear. Hope things work out for you!

jrcart

LMAO....so true

LMAO at the dick measuring comment, not that the OP got his motor blown up

jrcart

Where do you live? Are you in the Chicago area? Sorry to hear about your troubles, I hope things getted worked out. What other mods are you running? What kind of tune did you get from them?

If I had catastrophic engine failure 5 days after installing a tune then that would be highest on the list of probable causes. Legitimate tuner should be bending over backwards to assist the customer gain an accurate diagnosis of what happened. If fault is deemed PROBABLE then make things right and ensure it doesn't happen to another customer. Civil issues don't require absolute proof because it is often not possible but shady companies point to that nearly insignificant amount of doubt to justify leaving the customer holding the bag.

loungn14

oh Im not disagreeing with you at all. I just need the full details before I would chime in and say it was a tune failure. What I do find interesting though is that I know FMU well and know what they do with tuning. Also keep this in mind, this last week in chi has been very cold, high speed runs with this temperature and add some detonation and by by motor.

jrcart

Yep, that's why I run a wideband gauge on my car. I really want to know more about the OPs car, mods, mileage, how was he driving the car when it popped, etc.

C63newdude

Sorry to hear about your issues. By the way, how do you know that you have two bad pistons ? have you done a compression test?

loungn14

as do I my friend, and I have the same questions.

I also run a phormula ks4

Linky

One of the best devices I have ever had.

j bro

do they do there own tuning or outsource it?

The weather comment is exactly the type of evasion mentality that I was referring to, I am surprised you served it up. Everyone flocks to the dragstrip as soon as it gets cold and no one has had a 63 motor grenade on them yet as far as I know. In the OP's case, if his car is still under warranty and had stock files on it then MB would be taking care of him. If his warranty is rejected because of a tune then the company that sold him the tune needs to accept accountability. Bottom line is if you sell a product that you know may lead to the rejection of an otherwise warranty issue then be prepared to step up.

loungn14

Evasion mentality? Maybe you misread what I said. Any tune should be fine under any weather circumstance. How in the world would anyone tell you ya, just dont run the car when its cold????

Colder denser air = you need more fuel. If the ecu wasn't able to provide that, then bingo you have failure.

This was the first real week in chi that we had colder temperatures this season.

GHAZAN

isn't the MAF supposed to adjust for those slight variation in weather though? we are no talking about a nitrous shot

_AMG_

Alot of questions need answering.
OP where you at?

loungn14

correct it does, but software can also play with that.

yup, here we go again..

outsource at last i heard...

C63newdude

Could it be OEtuning and Fluid -Motorunion being the same tune just different names? I am just guessing here but I could be guessing right..... Not hating, just saying.

FluidMotorUnion

Can OP chime in on what happened? This is the first we're hearing of anything like this?

Any specific reason why you joined MBWorld today and felt it was necessary to comment on some other cars before bringing up a matter this serious?

We don't have anything to hide behind, if this is a legitimate accusation please call the office or e-mail me direct at mmarzano@fluidmotorunion.com

jrcart

That's the exact point Lounge14 is trying to make, not sure why you guys don't understand his point. All a tune is is tweaking timing, air and fuel, push it too far and the mafs and such might aclamate in certain conditions but but be able to properly aclamate in other conditions that can lead to too lean or too rich, rich isn't a huge threat but lean will melt down a piston pretty quickly. I can attest to the temps here late last week and this weekend, Sunday morning it was 38 degress when I woke up.

OP needs to chime back in and answer some questions, I hope this isn't going to be like that last thread where the OP disappeared for 8 pages before ever adding any other info. If you are going to start a thread be ready to participate.

jrcart

The 4 post count of the OP did have me questioning the validity of this. Good idea to chime in, very professional response. The fact that you guys have not heard anything is a big red flag, if this is the OPs idea of a joke you guys need to get his IP address and take action.

FluidMotorUnion

The OP is obviously not aware of how serious a forum can spread negativity like cancer against a companies name.

Like I said before, we have nothing to hide, if this was legitimate I would of at least expected a call or some type of contact before a random forum post?
