Wildem Posted February 19, 2019 Share Posted February 19, 2019 Non acvs. Ej207 heads,ej205 intake and harness. Upon first startup i recieved a p0340 and p0171. Cleared it came right back so i decided to take a ride.bad bucking,no power, backfiring, i used the cam sensor that came with the heads. Timing is good. My question is am i going to need to go straight for a tune being im running different cams than the computer knows? Quote Link to comment Share on other sites More sharing options...
Wildem Posted February 19, 2019 Author Share Posted February 19, 2019 SOLVED. Jdm cam gears are not the same as usdm. The sensor will not read the jdm gear. Solution: Swapped the gears over to the usdm ones (yes timing marks are still the same aswell as keyway) 2 Quote Link to comment Share on other sites More sharing options...
