stay tuned for the next epsiode of..

"when tunes go bad". stock k16 tunes should not allow for spikes of 1.3 period. that's gambling with very little upside.

 

my 996 held 1.2 octane and spiked at 1.3 all the time.
i put close to 100k on my 996. and every mile was worse and harder than the one before.
never an engine issue.
NEVER A SINGLE ENGINE ISSUE.
i put 87 octane in it when i drove down to florida and beat the snot out of it. no issues.

my 997 is on its 100 oct file and i run 93 on it (getting the lockout code reset this weekend) and i've had no issues.
ive had the car for 2 months now. have been using 93 and beating the **** out of it. no issues.

youre fine on 1.2 all day. youre fine on 1.3 all day.
if your tuned by giac, UMW, or custom tuned by a real shop, you will be fine.

 

+1 Unfortunately, the OP isn't listening.

My guess...this OP won't tell us when his engine detonates.

Here's the formula....
(K16's + 91oct)*1.3 bar = BOOM

 

a k16 car goes boom at 1.3 on 91 ? but its on ok 1.2 ?
doesnt make sense to me. my k24 car never once gave me an issue

 

So OP states that the cheap re-map was less than $1K.... Didn't EPL just run a sale for a 1 bar map for 899.00 ? And when I had EPL 1.0 bar map, I did run 1.2 bar in cooler weather.. Did the "tuner" push a little or is he posting peak numbers that were seen with this map. Short of data logging, I don't think that this vehicle is pulling consistent 1.2 bar unless they live in northern coastal areas of kalifornia where the weather never gets above 70 degrees and the fog is as thick as the smoke from burning cannibus plants

 

New to P cars but NOT new to performance mods...if you run a 100 oct tune and only run 93..your PCM is doing the work in saving your engine. I can't see how you would not get knock..will unless you are running really pig rich but then why would run a 100 octane tune.

wow all I can say

 

Yes.

No. K16's are typically flashed to achieve 1.0 bar.

You answered your own question here, Steve.

 

I would be really concerned about fuel starvation and a lean condition. Data log it and make sure you log injector duty. I bet they are well over 100% at 1.2bar with stock FPR and injectors.

Unless they have pulled a lot of timing and just increased the boost on that file, then it will be just a matter of time before kaboom, IMO.

Data log it to be sure it is safe. These engines are not cheap... $300 data log saves $20k in engine repair/rebuild, etc.

 

Agreed, You are so right..

 

^^

 

sadly many people who mod their cars are more worried about carbon fiber accessories and not what the engine is doing. they assume because a tuner loads a file it is safe and nothing has to be done. far from the truth.

for me i invested in the durametric before i ever bought the car just so i could see the over revs and find out how the software works. it has proven to be an absolute necessity when i was chasing codes and misfires. i wouldnt touch an engine without some form of datalogger

 

I agree. I got my Durametric from my old indy mechanic who upgraded to another system. He always let me borrow it anyway! It's a pro version so unlimited VINs!

 

I'm in the same boat, I have Durametric Pro cable on "long term" loan

 

Thanks, guys I need to invest in a Durametic or if someone's taking a nice long drive on the coast between SF an LA (with Durametic). If its not running lean, I want a commission for this local tuner who beats all prices! Because this tune will blow you away.

 

kP,

First off, I thought it was your buddy's car and not yours. Secondly, it seems you're ignoring all the experienced advice from collective decades of Porsche ownership here. And lastly, you're talking commission now? For the very tune you were ostensibly questioning in your original post?

Seems legit.
