Still getting my HR swap finallized and tuned and look at this! My intake cam timing was always funky when I was tuning or data logging but then one night, I noticed it was either at 0* or 60* with no in between. Started by checking the resistence and functionality of the vtc solenoids. They both click open when connected to the battery and measerued 8.1ohms on my cheap ohm meter. Spec is 7-7. 5ohms so the resistences are a little high. Maybe my readings are just a little off because of the device I used since its in the ball park. Anyways, after both those check out good, I pull my cam gear covers and intake cam gear retainer plate... holy hell haha I think I had a cracked cam gear from before I even built the engine! Always was leaning out and getting a cam over advance code for low rpms and low throttle. The crack would allow the oil pressure to build differently in the gear and not allow it to advance or retard properly. Then I guess the crack finally propagated and put me in the place I am now




For my own tuning purposes, would anyone care to share their uprev intake cam maps? I left mine on the stock map I got from uprev. Also, if anyone has a intake cam gear laying around, PM me!
