Ok, so I have a 97 civic hb w/b18c1 block,b16a head. I got a gsr ecu to used to pass emissions. The cel comes on at start up and throws a p1259, and p1337. the p1337 is from the ckp fluct. sensor not being wired up. Oh yeah I normally run s300 in a p28. So with hondata vtec works great. With the gsr i get the code,(I don't know if vtec engages i haven't driven it to see if it will engage) I did the wire bypass for the lack of ckp fluct.sensor and vtec pressure sensor back when i had the full jdm b16a motor so I not sure if anything else could cause this? I'm going to look at the wiring to see if anything has come apart on fri. any ideas would be great.
