Today it let me pass 6 k but I do have cel one for electrical overload one for the secondary 02
Im running a integra type r ecu PRC
alright so i found that if i hold the rpm at around 5500 rpm i can take it up past 6 still have no idea what is causing this.
Well the thing is i don't have vtec at the moment because of my speed sensor.
So i'm guessing i'm just going to have to get kpro to fix the problem . At least the price went down !!!
yeah that's for sure thanks man i will stop by Auto zone sometime this week and btw what is the oil pressure level supposed to be at for a k20z3?
well i was planing on getting a S2000 cluster. I saw on here there was something you could use at radio shack for $5.00 to convert the frequency on the vss . but it would only work on kpro .
Yeah thats the thread I was talking about really want to try that out.
