Talking about ecus,that rev cut problem that I was talking about turned out not to be the oil pressure/oil level. I disconnected the mechanical speed sensor since the speedometer was going awire and it hit a 6800rpm rev cut again. I must of f-ed up somewhere putting the sentra back together, but I dont understand why my mechanical driven speedo has anything to do with my ecu especially with my ecu having speed cut. I think its getting or giving a signal from nor tps, timing or o2. As the speedo fluctuates, it boggs down the car as the mph approach 0mph. Luckily as the speed increases, the speedo fluctuates +/- 15mph at about 3 times a second rather then 0-80mph. That is causing stuttering, but after 2nd gear, its almost unnoticeable. This is a first for me, I'll try to figure it out tomorrow, but either way if I figure it out or not, I think its quick enough to compete so theres no question that I'll show up.
