Tried to set my car today, everything was ok, except strange fuel cut. That happened at 3500-3800 revs, load 140-180. ECU would cut the fuel and AFR (measured by innovate LM2) would jump to 14,3 and then it would knock.

Boost limit set to 300
Boost cut delay timer 256000
(boost is controlled by apexi avc-r)

Any suggestions why would this happen ?

 

go back to stock solenoid, and check first with xml i sent you, my car with the rom i sent you works amazing, and still within safe limits
ps.you are gettting some boost spyke and it cuts your fuel, log 2byte load with xml i send you and see what load you hit there is probably over 300( is the rpm range for max boost for stock turbo)

set you 2 byte table in you rom / or just use mine as is already set and immo disabled

93660005
2byte load
MUT 00 = 8960
MUT 01 = 8961

2byte RPM
MUT 02 = 893E
MUT 03 = 893F

 

i suspect ur BCS is setup wrong. ur boost is spiking as he said above.

check ur lines.

 

I logged everything, 2 bite load, RPM, knock sum, timings, AFR from innovate w02. Everything stays where it should be. I limited apexi avc-r to 0.8 or 1.25 bar just to safe before I set the car, load doesnt go further then 180-200 on 0.8 bar of boost.

I was looking at the map tracer and all the values were alright , exept when the fuel was cut, the afr jumped to 14.3

Also I looked at the the AVC-r and it didnt register any boost spikes.

 

did this happen only once? or everytime at same rpm and load?
check spark plugs, best for increased boost on evo 8 are the ones from evo 6 tme and spark plug leads
did you try the rom i sent you?
