changed injectors, quick map setup possible?

[mr-alternative]

I got a mapped PRA K20A2 with 12:1 Wossner pistons, JDM FD2R camshafts, RBC intake manifold, Injen CAI, JDM DC5 exhaust manfold and cat converter, 70mm Fox exhaust catback.

Car was dyno tuned in may and got 85-87% injector duty cycle.

While its a car for street and trackday use i decided to get new fuel injectors. I changed the stock (310cc) to 450cc Deatschwerks injectors now.

The engine got problems with spark plugs in 2d and 3th cylinder, happened after changing the spark plugs.

Cylinder 2 damage came up after 700 kms, then cylinder head was removed and all valves got replaced - spark plug itself got detonated, mass electrode full broken and ceramic itself got cracked too.

Cylinder 3 damage came 150kms after the engine was put together, same failure as cylinder 2.

Before the car was driven 11000kms with the spark plugs putting in when engine was built (7000kms with a good running wiseco map, then 4000kms with a setup from dyno).

All spark plugs i have seen on a k20a2 CTR were grey to white colored (stock engine), so about air/fuel ratio about 14,7:1 tending to a bit lean.

Now my fuel ratio is generally to rich due to the injectors.

So my questions are:

Got someone had the same or similar problems with spark plugs and was it a problem of spark plugs, fuel injectors or mapping setup?

Is there a way to get the hole fuel map a bit leaner? Acceleration is not so good at the moment as before while its too rich.

I checked vault for maybe another map i could use to setup it for my car or use it temporally to get to the dyno (400kms), but i only find PRB maps.

Is there a way to convert a PRB based map into a PRA based map?

Didnt solv the problem yet.

In the parmaters section i could normally adjust the fuel trim generally by changing the injector size from 310ccc to 450cc, but when i have a look into the fuel tables, there is no change.

Added the 310cc map, maybe anyone could give me some advice how i could fix it or change the fuel tables by changing.

The fuel tables will not change when you change the injector size. IT is modifying a injector multiplier behind the scenes.
