****.

While driving to my girlfriend's house, I boosted to test out the new M2 Stage III ECU that I bought last week and installed yesterday. I wanted to see if I could feel a difference. Well, I made it to 10psi on the primary, and switched to the secondary at 4500 - boosted to 12 psi, and then everything went shitty. Loss of power. I slowed down, then tried to accelerate again - turbos spooled, but car wouldn't go. I got it to my gf's house and popped the hood - engine was shaking like it was having a seizure. Boost gauge was at 12 psi of vacuum. MAP sensor was in place. I think it's done.

The thing is, this engine was only 8 months old - and I babied it 90% of the time. Just ask Ryan...he knows I never redline it or anything, and it was properly broken in. However, I had the dealership install it, and they did EVERYTHING wrong - couldn't even hook up the BOV right (Chris Sanders knows first hand). So, I called them up (service was closed for the weekend) and left a message with the secretary....that they are GOING to get me a new engine and I am NOT going to pay for installation.....They are going to pay for Chris (Banzai Racing) to install that engine or they are going to court. I have HAD it with their incompitence.

BTW, if you want to read up on my previous experience:

Also, when the car was idling (very rough) blue/white smoke was billowing out from the catalytic converter area....not sure what that means, if anything. I didn't see the CEL come on at all, either.

:sigh: Time to go cry again :cry:

 

I hope you are ready for YOURSELF to get the engine and YOURSELF to pay Chris to install it.

I'm sorry this happened to you, but according to your message in the other thread the last date of anything was April, not to mention Chris supposedly looked it all over afterward.

Buzzfish on here had a much easier complaint against our local dealer than you (car left after maintenance with a blown motor) and they wouldn't pay anything. Now they are in the courts. Currently Buzzfish has paid for all of it and is trying to recoup cost.

 

I love'd the first line of this thread, made me laugh

Its defintly tough to find someone to work on these cars, I went to a dealership, and theyre like what kind of car do you have? I said "93 rx7," reply: oh, sorry sir we dont work on those.

****.

 

I am on my 4th motor this year. And I had it at a So called "Excellent rotary shop" No one takes the time to do everything right before they hand the car off too you.

 

4 motors in one year! You've got to keep your eye on shops but could your car's appetite for motors have anything to do with your sig "404 rwhp"? Seriously, that is some big HP, nearly double the stock output.

 

his car has everything it needs to be reliable except the person who put the car together. THE MOST IMPORTANT THING

that will be taken care of now though

 

Actually i think my engine will still be under warrantee, so I should get that free anyway...I hope.

 

was it a reman ? if so it has a 1 year warranty. so you should be fine there

 

Even if it's a one year warranty, they won't cover everything. Just like Pineapple's warranty, they aren't going to cover you if you stick a midpipe on the car and run it lean.

They will cover standard mechanical failures, not improper modding mistakes.

 

you would be surprised. judge ito got a few engines from mazda that were built wrong..... man that sucked

 

Well, I don't have a midpipe. I only have an intake and a cat-back exhaust...and I had those when they put the engine in. I just upgraded to a richer-running ECU.

 

Exactly, *if* there was an assembly error. That's not unheard of but more rare these days.

And that alone could cause the warranty to be invalid. That's like saying all you did was add the PowerFC base map, it shouldn't blow the engine. You never know with these cars.

Also, you never know who is reading these forums, so I wouldn't post too much info until you have gotten back with Mazda. In any case, I would definitely put the stock ECU back if you still have it.

 

an aftermarket ecu will usually void the warranty.

 

if you look at it funny it technically voids the warranty. mazda generally speaking will warranty the motor or so i have heard

 

Nah it wasnt the motors fault it was the Shop who did the R&R. One after taking it to Judge Ito he noticed the Wires going to the Crank Angle sensor were reversed and one of the secondary 1680cc inj was left unconnected and the wire had shown alot of grime on its ends like it hadnt been connected for a very long time. Like maybe 4 motors ago. I have been building this car for relibality and big power. But no motor is going to last when the Install is Botched. I gave this shop alot of money and time. I even ignored the people who warned me not to trust them with my car. I didnt listen and had to learn for myself. This New motor will put down big power. 404 was on a Stock reman. This motor I have now is a Large Steetport capable of much more.

 

440 @ 15psi shouldn't be hard

 

I'll switch back in the stock ECU then.....and it should still be under warrantee, right?

 

Take the car to A-spec. Dont deal with Mazda dealers. The motor will priobably be warrenteed but pay a competent shop to do the R&R. A Rotary specialty shop prefered.

 

I have the shop in mind that I want to take it to - Banzai Racing. Unfortunately for me, I didn't know about Banzai or how bad dealerships were when I had my last motor put in. I have since learned, and won't let them touch it.

 

I would be more concerned of what made the engine go in the first place. Just make sure that whatever shop you use they check your entire fuel system. I don't care how well the engine is built but, it wont last if you have insufficiant fuel delivery.

 

well, I think that you will end up paying for a new motor, just my opinion.

 

If thats all the mods you have, then you should be using the stage 1 ecu. Just because the #3 ecu runs richer doesn't mean its safe. There are differant timeing maps that you have to worry about for each stage ecu. The stage 3 is good for intake,intercooler,downpipe, and cat-back. It may not work for your current mods.

 

Yikes.

Rotary engine modding, building, and installing is like a dying art. If even the dealerships can't be trusted, who do you trust if you can't do it yourself?

 

I don't think the differences are all that great...there's no way the Stage 3 caused these problems. Its certainly overkill for what he has though. To be honest, the stock ECU would work just fine...downpipe and cat back are NOT going to cause the stock ECU to run too lean.

Original poster: How sure are you that the motor is toast? Did you check the connections to your MAP sensor? When that hose pops off you'll think all hell has broken loose.

"The thing is, this engine was only 8 months old - and I babied it 90% of the time."

You leaned out, detonated and just chucked an apex seal.

Sorry to hear about your misfortunate, it SUCKS, but learn from this. I'd start investing in tools and find a reputable shop to build it for you.
