I have not logged that, what is the reason for bothering with this? Smoother idle or more lop lop lop lop?

more lop lop lop lop
Definitely a reason to fiddle with it.

In a way smoother yes. I guess some people have had oil pressure issues at idle, or what they think are oil pressure issues. Apparently below like 1200rpms the car goes all the way negative on the exhaust cam and all hell breaks loose. Just curious if you have had any issues.

[scheides]

Heh, I'll look. My idle is rock solid, probably around 700 or 800 rpm. I've been having some surge issues with the new TB but it's only when the car is moving, it's weird.

[Murlo26]

Strange about the surge...hmmm. Leak maybe?

Yea I guess if you get a chance just let me know, just curious.

Have you ever logged mivec at idle? Target vs. Actual? I got a call from John from Akuma motorsports today about his mivec going all the way to -35 at idle and was curious if you were seeing this at all. I don't think I am but not sure really and I can't test it on my car.

I should log mine for a while. At idle it is good when cold, but once the car is warmed up, it gets really choppy and AFR's jump to 15-16+. Eventually it will even itself out and it will idle smooth until it dips down low again. Unfortuantely, I don't know a ton about the tuning, reading of the tables.

Here is what I was talking about Scheides:

Honestly I don't think my car has these problems but I don't know for sure.

xmas update.

Installed some weatherTech floor mats this weekend:

These things are really nice! They fit like a glove and are already nice and dirty from use :)


Speaking of dirty, I found this on my intake ports/valves when I had the IM off recently:

After a bunch of research, I've taken the advice of aaron @ ER and Shane @ DB and just switched back to pump gas for a few tanks. I added a bottle of chevron fuel injector cleaner to the first tank, hopefully this cleans things up! Switching back to pump was dead easy on my setup: turn down MBC 3 full turns while filling the car up with BP93, fire it up on the e70 lingering in the lines and then hold down cruise control button after about 20 seconds. Car runs mid 11's AFRs and boost just touches 24psi in 2nd and 3rd, 25.5 in 4th. WGDC is set to zero across teh board so this is pure mbc, taper and all. Not ideal but the car still rips pretty good!

The car had a handful of CELs that would come and go but the last month the CEL has been on solid. po300 (random misfire), po365 (exhaust CAS), and p3000 error. po300 and p3000 are now gone after 1 tank, and I discovered that my exhaust CAS plug was loose--it had slightly melted from the tubular manifold before I put a heat shield and heat wrap tape (thanks again lomker! RIP!) over it. The pin was also bent really bad from when I was swapping manifolds on the dyno back in feb so idk, maybe the sensor is bad, maybe it just needs more TLC. I've seen people reporting po365s as a result of a misfire so I'll fiddle with the plug some more and probably try some new plugs after the holidays and see if that helps at all.

[goodhart]

is there any patches to disable the p0300 and others like there is for the 8/9? My car would get that all the time before I disabled it, even with a good tune and no noticeable misfire.

[scheides]

I'm not sure, it seems to have gone away though...and considering the other CEL, I might want to know when it's actually doing this...I had zero CELs all summer so this is def an indication of some issues. Nothing major though.
