p28 chipped issues

[jacked_77]

I just finished my b16a2 swap and I have issues with the fuel map as I hit 4800-5200 rpm my motor stutters and puffs black smoke
I switche to my 93 SI p28 and had no issues with the full rpm range.
I opened the chipped p28 it is chipped on a bridge so it is removable
Can any one help me with info
Thanks

Is the ecu chipped to handle your 310cc injectors? Or does it have a stock injector map on it.. that would definitely be the problem.

my car had the same problem and it turned out that my progam was for 310 injectors and they just typed it 255 because thats what i had in the car so the map was running my 255's at 127% duty cycled a 6000 rpm so check it out because if your map was for a car with bigger injectors yours will cut off because they cant run over 100%.
