The way i know is that in my final gear on the hwy at exactly 70 mph (Gps) I'm at 3012 Rpm .
So 70/3000=0.023333333333x6700= 153.33333

 

Just thought I would give an update. Car has been running great pushing 14-15 psi. RyanCB and I will be bringing both our cars to English Racing on Feb 3rd which should be alot of fun :-). I still have my idle dips. Still cant figure out the problem. Just put brand new plugs in yesterday hoping (although assuming no) it would fix or help the problem which it did not. Hoping maybe Aaron down at ER might give me some insight and steer in the right direction on how to solve this issue. Seriously debating replacing the front 02 sensor but I still dont believe this is the issue. I can switch to full open loop even at idle to bypass the 02 sensor but I still get dips which leads me to believe its not the issue does this make sense? Any thoughts?

 

I have kind of the same issue but its because my belt is slipping on the altenator so the voltage drops as well as my rpms until the belt grabs again. It's real quick though.

 

Here is what my car has been doing for the past couple months. With my awesome cracked cluster cover lol. I wanna know how someone did that.

what dv are you using? the evo one?

 

he is, mine is doing it as well but not as bad. We both are fairly sure its in the tune.

 

if both of you are doing than it would definitely be something in the tune. In the video it sounds mechanical but if both of you are having the issue then its different than mechanical.

 

I think last thought was something with ISCV table since it seems coolant temp related.

 

mine also does it, and dies after high revs when im stopped. or when i pull it out of gear.

 

mine used todo that with the lightweight flywheel. haven't been pushing the car hard as of late but it deff hasn't done it as much.

 

I have messed with those ISCV table till my eyes bleed lol. I may be missing something though idk. BTW Ryan I make good headway on that explorer tonight so hopefully it will be all done tomorrow before work

 

yeah i tried everything in the tune to make it stop doing it with no luck. can the dv being open at idle cause any of this?

 

I have no idea but i think that shouldn't be the issue since I'm on a diff dv then you guys.

 

I ran same dv for a year and a half with non of this crap. Dunno what changed honestly

 

also makes no sense why when cold its fine
