Me too, my damn PLX devices AIT's don't work with their AFR module plugged in. It someone injects enough noise in the lines that they report way too high and spike.

For you guys that have installed this kit, how well does your dipstick seal when it's seated in the tube? Mine doesn't seal well, it sort of rattles around. I'm thinking that I'm missing an o-ring.

F,

Do you have any oil drops around the dip stick? I doubt it, the dipstick tube has a o-ring groove with a wide top to accept the tube. What you are hearing when you move it around is the wide top of the tube hitting the inside of the dipstick receptical.

Either way let me know!

I have to admit those are some bad ass side scoops.

Hi Jermaine,

It's not a big deal, I didn't figure I needed to bug you about it. No oil drops, just the dipstick wiggles a lot even when it's seated. I was worried that water or unfiltered air could get into the crankcase, but if you say it seals, that's fine.

Jermaine,
Is it safe to drive the car hard, such as going to the track, with cel code P0420 and P0172 System Too Rich? What could potentially be damaged?
Your vf2

Piston rings, o2 sensors?

Too rich can damage the catalytic converter...

Jermaine@VF · 08-14-2009, 05:35 PM

In an extremely rich condition you can do damage but in this case it is not a big deal. It is just barely out of reach of the ecu's parameters. Nothing to worry about.

The P0420 is a bit odd, since none of that was changed on the ecu.

stinkyonion · 08-14-2009, 06:31 PM

Im cracking up over the "dipstick wiggles" complaints. I had the same complaint when I installed mine many months ago. However, the stock dipstick wiggles just as much. Put your stock back in and you will see. When I spoke to Jermaine then he said it was a Lotus thing, and that they might get around to making a better dipstick than lotus stock. I guess they havent yet. Many months of driving and it hasnt been a problem. Just make sure the dipstick is secured to something. Mine is held tight inside of the loop of the PCV hose.

I have the tumbling too; must be normal.
Do you have hesitation below 4000rpms or any hesitation?
It feels like turbo lag with my vf2.
The car is very fast, but hesitation is really becoming tiresome.

The offer still stands for a check up on your ride. Couple hours is all it should take.

Last week, I had the same problem around 3000-4000. It was the first time I had an issue with the VF II. It was very hot-humid that day...
I swapped the plugs,(but same thing) checked the coils, injectors, checked for leaks,(thighten all the couplers) cleaned the MAF sensor, cleaned the air filter. No MIL. Short term fuel trim OK ( -3/3).
Today, after 2 tanks of 94 octane gas, it's running better but it's not going to 8000 rpm as fast as it was before... And my AFR gauge is showing higher numbers at WOT than before, but it could be the gauge, after all, my boost gauge is showing peak boost of only 7 psi ...(same as with my Katana)
All I can say is that something happenned, I would like to say what... but...

You have a leak somewhere no doubt about it!

Jean · 08-19-2009, 09:58 AM

It looks like it Jermaine,
And I did check with care...
Did you discover a common issue that is hard to find ?

Thanks

Generally no...

Check the outlet from the SC.

Jean · 08-19-2009, 11:44 AM

What a shame !
Last Sunday, (I can't tell you why, it always happens when my wife is in my car) a new 2009 911 turbo came by my side ...to play ...( don't worry, nobody's around)
I am still wondering if the small hesitation at low rpm with my VF was the issue or my wife's cry out...
Usually, the GT3 is a lot of fun with the VF II...

LordZ · 08-19-2009, 11:52 AM

Mine has lagged twice now on me. One time was when I was crossing an intersection. Almost got tagged by an 18wheeler, that was the first time it happened. 2nd was just at a stop light.

1st time car was fully warmed up in the am
2nd time car was cold in the pm

Other than those two times all seems well with my setup now. Idle is still a bit off if I turn the AC off, but with it on no issues at all.

I know, but I am really busy during the summer. I'll be sure to see you guys
late fall or so. Thanks.
The car runs strong as long as you are hard on the gas, which is how I drive so I am really happy in that regard. I think one of my o2 sensors is possibly to blame for the hesitation below 3500-4000, but that is a blind guess.

Could a slightly rich condition clog-up the cat?
I was considering swapping out the cat for my de-cat pipe to see if things
change...what is your opinion?

This is revealing. I live on the East Coast where it is extremely humid during the summer, ranging between 50% and 80% I would estimate. Maybe the humidity causes the hesitation to some degree? (no pun intended)
