Hey guys, I have a jdm b16 in my 93 ej1 (I am the 2nd owner of the engine). Ok well I was running it on a virgin P28 for a while. Finally got it chipped and my buddy said use a P72 GSR map instead of a regular P30. So I said sure what the hell...... Well when running the car on the birgin p28 it ran ok...I mean no power or anything but thats off the point. Now when I drive and I shift the and take off the clutch and put on the gas the car falls on it's face hard then picks up. When I am cruising if I punch the gas the car back fires.. and the car has NO POWER!!! like really slow for a B16. It did NONE of this when I was running it on the virgin P28 only started once I had it chipped and running the P72. Do you think that it's the P72 GSR map doing this or because I am the 2nd owner and the 1st owner beat on the engine does it need a rebuild? please help!

 

did you try another ecu?? Maybe it wasnt chipped correctly

 

Dont have another ECU

 

please help! lol someone!

 

anyone?

 

it's possible that the maps are off...i'd try the p30 map

 

It sounds like the GSR maps are you problem.
switch to a B16 map (the P30-203 code base from Crome works great on a B16)
