First exit after the long winter period

 

Wow....sounds great!!!

 

How did you store the tires so they did not flat spot over the winter?

-Yogii
AKA 968 Novice

 

Tires on the rims = stacked horizontaly
Tires alone = vertical rack
Wheels on the car = car on supports so tires are not in contact with the ground

 

Never gets old looking at 'er either!!

 

The wintering is over, the 968 is brought home.


.
But we have a problem because the cylinder 3 does not have the right temperature despite all the research done injectors, coils, spark plugs, exhaust temperature sensor, all are reversed without solution)

The appointment at MF Power is scheduled for April 2 to complete the battery of tests on the ECU and find the why of these cuts at full load

 

Is it less vacum and lower EGT on syl 3 ?
What`s the compression ?

 

Cylinders 1-2-3 = 9 bars
Cylinder 4 = 8,8 bars

 

 

Everything is OK.Pressures, water and oil temperatures.The engine starts perfectly well and no cuts to acceleration.When we start to run These cuts occur only when we run and we accelerate thoroughly on the 3rd report.The car accelerates well on the 1 and the 2.

 

Cuts on third, ok, meaby missing some fuel when you load the car hard. How is your fuelpump system?

 

Three fuel pumps new !!! No missing fuel because the spark plug n°3 is very black. May be ignition injector n°3 fail. I hope when the car will be on the dyno test, we see the default with the PC connected on the ECU.

 

Do the ECU delivers 12v to the coils or do you have a seperate relay for this?
I have had some relays going bad, and only delivers 5-8v and dropping out on high rpm+boost.

 

The ECU delivers 12V directly to the coils, .And the system is " Spark Ignition Lost" because we have only 2 output on the ECU: coil 1 & 4 and 2&3. . So, I am sure that 12V arrive well at the coil 3 ( The cylinder 2 have good combustion)

 

How are the coils conected to earth?

What Ecu are you running?
