    hey, i just finished a b18c5 engine swap into my 94 eg. im using a chipped ecu with a stock type r basemap tune. The car starts but runs very bad, it shakes at idle and seems like its missfiring.

    i dont know if this matters but if i unplug my maf sensor it still stays the same, in other words the engine dosnt change sound, i dont know if thats a normal thing.

    i just tried a friends 98 jdm type r ecu and it ran the same but with that ecu i was getting 2 codes:

    20 Electrical load detector

    41 Primary oxygen sensor heater

    with my chipped ecu i had no codes

    can anyone help me out in any way?

    thanks alot

    I'm just making a wild guess here... so forgive me if I'm wrong but it looks to me like there may be an issue with your MAF sensor. Since you took it off and it stayed the same, that's not right.
