hi guys

I had an elantra 2002 2.0L, I blow my engine like a 7month ago, I broght another one from a 2003 CVVT tiburon but just the long block, no intake or exhust.

I use the elantra sensors, harness and ECU.

the car works normal but spend to much gas 19mpg!!!!! before I connect the CVVT was at 16mpg city

so I thing the problem is the ECU and the parameters due the cams diferents.

if someone have any other recomendation will be more the welcome

for now I need an ECU

Thanks

with the stock engine (elantra) 24mpg

with the CVVT engine at the begining 16mpg

after move the craft pulley 4° (-) plus the CVVT always on 18-19mpg

so I think is a problem of timing with the computer beacuse is not CVVT
