You've lost an apex seal in both rotors.
On a normally aspirated motor with low miles like yours, the only way to do that is by detonation and the most likely culprit is the failure of both leading coils.

Giorgio I had done the engine computer recalls in the past.
I never use Premix
As the situation of the fuel pump is ok.
Now for the maps i don't know anything what he made on my car.
MazdaManiac i saw that i lost both rotors and this is the reason that i am trying to find where could be a mistake or something wrong on my car.

 

Since I know personally dipatrx8 and know his story let me try to rephrase some facts.

Well everybody can see his tuning here

“COSMO with:RACING BEAT REVI-RAMAIR, MAZSPORT IGNITION SOLUTION, AGENCY POWER UNDERDRIVE PULLEY, MAZSPORT COOLING FAN CONTROL KIT, FEED 4.777 final gear, RACING BEAT HEADER, HJS HI FLOW CAT, ΟΝ EXOTIC SPEED MID-PIPE, COBB ACCESS PORT, HKS Titanium Muffler”

His car was at a perfect condition a month ago. His compression was very good and was running strong. During a run I guess due to pinging he “lost” his engine at the highway. Compression in both rotors was gone ! This is a sign of too high avans in my opinion.

Easy tuning said that will provide us with any information about the maps; However, mazdamaniac I know that you are the most experienced Mechanic concerning AP. Would it be possible to examine the dipatrx8 maps and give us your opinion? If yes what dipatrx8 should do in order to send you the maps?


And why you say Do you have any clue to support this?


Thanks

 

thank you Rotary pilot for your services

 

Losing the leading ignition - for whatever reason - will produce catastrophic detonation.
If the trailing is the only thing firing, regardless of the actual advance, it will ping mightily at the torque peak.

Yes.

 

So can you give us some explanations about how is it possible to lose a leading ignition ? Do you think that the ignition coil is responsible for this or something else?


Can you please give us some clues about Easy tuning and why you support such claims? PM me if you want.

 

The Mazsport ignition coil amplifier has been known to fail. This could cause a loss of coil power to leading plugs. If he lost supply power to the coils it is possible to cause catastrophic damage the engine.
