Did you ever log the car? it would probably save your motor...

 

yup, was meaning to do it many time - never got around to it. 1st stop after it gets rebuilt...SamboTT.

I really want to get rid of the 9ff program though. Is that necessary? or can we make modifications to their map after logging it?

 

If your not happy with that tune take it off.
You don't want to be messing with someone else's tune plus who knows what's been done.
Also, check make sure They don't have the EPROM hoc soldered on top of your oem one on the board.

 

Mark, if I've had the same software that has blown up TWO M97/70w engines, is it the tune for certain?

Last time was the same story (although the 1st was dx'd the day before it blew up at Pioneer porsche w/ a tiny exhaust leak from the left head gasket) broke a con-rod and punched a hole in the block

Is anybody else out there using mezgers for IEDs?

 

When a motor is pushed beyond the integrity of its mechanical limitations it's usually the weakest link that will be the first to fail. Tuners should realize this and keep RPMs, cylinder pressures and spark leads well within safe parameters of the motor design. If in doubt, fail safe devices should be placed to monitor or control the activity.

I've never built or tuned a P motor, but I have built lots of high performance and race motors for decades. You need to clean your ECM and start with a fresh tune from someone with a successful track record.

 

That motor is cheap, hopefully all is well with it. Do what a couple of others have said and have it checked it before you have it installed!

 

Mark has some nicely dialed in Proto tunes. We can get you a loader and log to see what's up first. Then tune and make sure all is good. 1.2 is not too insane, especially on 16/24's. 24/26's are getting bigger. So many variables that data is key like Mark said. We can work together and get you sorted in sure. Get the love back from the car.

 

Yeah, that ebay motor was pretty sketchy. I wound up with a runner i found deep in the heart of Texas for a bit more coin. I had them ship the long block as the accessories i have are about 30k new. Low miles and everything seemed to check out.

Yes, I'll have Mark's tune and SamboTT's log n tweak.

Isn't it simply a matter of time though? if I get a proper tune, will I have to worry about my IED detonating behind me again?

Should i just Flash it to stock and forget it then dump it?

 

cool, you're half way there!.. what are the chances, you'll blow up another motor! if you're just gonna put it back together, then sell it.. why tune it yeah, i would put it back to stock to sell. less questions to answer!

 

I would let someone like Mark tune it first and then decide what you want to do. You're already in the car for significant coin. Flashing it back to stock and selling it as-is will just be a huge loss to you. Tuning it right will cost marginally more and you will end up with a more reliable setup than you had previously and you can at least enjoy your car.

 

Hey so sorry about your motor. Just want to add something. I have k24/18g and made 561whp at 700hp to the the crank. So im guessing with k24/26g your making well over 750hp to the crank the porsche cant take that on that stock motor and yes some say yes lots say no its the rods that are weak.


I understand the tune might suck but im glad your going with Markski he knows what hes taking about and has one of the fastest porsches.

 

My Car had K24/26 OLD school turbos. the Tune was 608HP I never had it Dyno b/c it ran great and was plenty fast.

 

If you launched two motors by breaking con rods I would say it's the tuning. Detonation is a killer on rods and puts so much stress on the engine. Engine failures are generally unusual, never mind TWO of them.

 

Wow that sucks!

What other mods do you have to the motor other than the turbos and the 9ff tune? It sounds like you bought the car with that tune on it? What other motor mods did it come with, and how much did you know about the tune?

I'd figure you should be able to find a motor for somewhere around $12-14k, with the 12k being cheap and the 14k more likely. I'd question anything less than this and figure you're getting what you pay for and I'd just stay away unless you want to replace your motor a third time...

 

My condolences to you man. That's some bad luck. I hope 3rd time is the charm with the next engine. You are already in things this deep might as well, get the new engine built and tuned right and then the car can run strong for you for 200k miles! I agree with you and others that the tune was likely the problem. Never heard anything good about 9ff. They probably had too aggressive a tune for only a 5 bar FPR. Injectors were likely over 100% duty cycle up top creating a lean condition that caused the failures.
