Ok guys, this is what confused me. All other DOCH motors have the vtec oil sensor but this motor that I have, its a 98 JDM GSR and it doesnt come with a Vtec oil sensor. Where the vtec oil sensor supposed to be is seal tight, its like the car was built without one. Also how do you tell a GSR ECU from an LS or regular teg ecu?? on my ECU there are codes but there are two big letters "G3" on the side. my cousin told me that when open the cover of the ecu, if its a GSR, it should state " Mugen and GSR with the R in red" and I opened my ECU and nothing wrote on. My redline limit at 7.8 or 7.9. Could it be that my tachometer is not accurate? or my ecu have been switched? what is the redline for an LS or GS integra? Oh, my vtec kicks in at 4.4 RPM. thanks for helping.
