Kens-E55

Sorry to report guys - Chris @C2 started the car up yesterday (after driving it the day before w/80mm TB installed) and got a "CE Light" so he has to
investigate a little today before it gets put on the Dyno. I'm hoping/sure
it's only something minor w/TB and Thermostat now installed, 'cause had no
issues what-so-ever with the K2.
Will keep everyone posted.

Hope it something minor...probably some wiring....

Kens-E55

The wiring was "Plug-n-play" - Hoping it's the ECU sensing more airflow
and throwing a "code"

If anyone can fix it, it's the VRUS/C2 team. You're in great hands.

Please please keep us posted so many of us can inform our installers as many of our cars are ripped apart as I speak....er ehhh, type.

Let us know just as soon as you get some answers, pretty pleeeaasseeee.

Thanks man.

Could it be the ECU has to be reprogrammed because of the TB AFR?

Hey Ken,

A couple of things:

1) Check the TB screws and make sure they are tightened all the way down and the crush washer actually got "crushed". If it isnt snugged down air will leak in from the sides and throw a CEL. (The welder may have allowed some weld to get through the cracks and up and into the holes for the screws blocking the path of the screw).

2) Make sure the PCV hose (The one I supplied) that runs from the bottom of the TB to the T-connection is on properly and hasnt fallen off the bottom of the TB. Also, check the T that it connects into. The hose that comes off the T and went up to the stock TB is a very small diameter hose. The intent was for the new hose that I supplied to slip OVER the existing hose and be fastened onto the T. Make sure that when it was fastened the stock hose wasnt pinched closed.

3) It could be a "Coolant Too Cold" code that you are getting with the 160TB.. Highly unlikely, but, possible.

I think Chris will need to hookup Star diagnostic to the car and read out the codes. That will make diagnosis much easier.

Good luck and tell Chris to call me if he needs any help.

A couple of other things:

- Was the car surging, sputtering or bucking while Chris was driving it?
- How did the car feel while driving ?

Kens-E55

Thanks Victor - I'll forward to Chris right away - appreciate the help and suggestions. I'm sure it's not a big thing-just need to diagnose.

vrus

Ohhh.... Ken.... One VERY important thing...

The harness that goes from the ECU to the TB & from the ECU to the BYPASS VALVE are EXACTLY the same (6pin connectors & wire colours) except for a small BLUE DOT on the outter black casing of the harness..

If the 2 harnesses were reversed it might cause some erratic driving and fault codes.. Ask Chris to double check and make sure those 2 harnesses were not reversed.

Also, with the car parked, the Y-pipe removed, and the air boxes removed, start up the car, rev it while watching the TB.. Does the throttle plate move in accordance with pedal input? Does it rev normally?

Kens-E55

Thanks Victor - I'm passing along as you give it to me - much appreciated!

Any update Ken?

Just let us know when you can.

Kens-E55

Talked to Chris mid-day. He said the error code was a MAP sensor error code. He was going to go thru the entire re-inspection of hoses and wiring to see if something was "missed". Hope to hear something tonight or first thing in the morning.

vrus

Ken,

How is everything going? Was Chris able to diagnose where the MAP sensor code was coming from? If he is still stuck please post the codes he is getting and I'll see if I can help.

Kens-E55

Hey everyone,
All is good!! Chris went thru the whole install again, reset teh battery, did a few other checks and POOF.......It's running "insanely fast" as he says!!
No CEL's and all is smooth. Will be on the dyno first of next week and then I'll hope to pick it up mid next week. Thanks Victor for all your input and help on this!!

vrus

So happy to hear that Ken!! I was sure the TB was ok and figured it was most likely the harness to the MAP sensor on the intake manifold that wasn't fastened securely. Whatever the case, KUDOS to Chris for figuring it out and getting your car running!

So, he likes the power does he? Anyone that has pullies & ECU should be buying an 80mm TB to put on their car.. It is a big difference in the way the car behaves overall.. I'm sure you'll come to that same conclusion once you get some seat time behind it.

Take care Ken and enjoy the *new* car..

Tell us more! Tell us more!

Honestly... you can really feel that much of a difference?

Just out of curiousity VRUS, this is basically the same kit that Kleemann sells right? Same specs? Same HP?

vrus

Everything I say I try to be as honest and exact as possible.. To me the car really behaved alot better with the TB installed.. Part throttle response, WOT, everything changed and felt better..

I'll let the others who have a kit speak up on their own.. BenzGal was the first, Ken was the second, Pasya is being installed right now, JakPro1 (Jim) is almost done..

I stopped saying it and figured others who had it installed would be able to confirm my feelings..

vrus

As for the differences between Kleemann Kit & VRP kit...

VRP ....................... Kleemann
AMG TB ....................... V12TT TB
80mm Y-pipe ....................... silicon hose to adapt stock Y-pipe to new TB
$2,500 USD ....................... $3,000 USD

Everything else is pretty much the same but different approach.. Both kits have a plate made to adapt TB to inlet.. I dont know what the kleemann inlet looks like but mine is ported to 80mm opening and insides are ported and smoothed also.

I haven't been able to put a V12TT TB in my hands to be able to give a Pros/Cons of using one TB over the other, so I cant guide you in that respect.

Oh Yeah... one more thing... I wont mention names, but, I heard back from someone who bought my kit, and , his installer said something like "This kit is better than the Renntech kit.." .. LOL.. THAT MADE MY DAY!!!! That's the God's honest truth!

Jakpro1

Just off the phone with service advisor. Going to pick up the car in 3 hours.

Service advisor asked Ken (SLR Mechanic/Installer) after he got out after test drive, "So how was it?"

He said Ken just walked away chuckling under his breath and shaking his head.

Oh, this is gonna be good!!!

dragonAMG

VRUS -- thanks for the detailed reply. Now all we need are some dyno numbers.

Is the 80mm y-pipe the same as the SL snorkle mod?

Looks like I'm going to be your next kit

vrus

Yeah Jim!!! Awesome!! Can't wait to hear your impressions of the TB with the SLR cams.. I think they are a match made in heaven!

Make sure you run right back to your computer and let me know what you think.. I'm dying over here.....

Josh.. Buddy... You know you want it... You know you do... hahahahahaha.. Sleep well my friend..

BenzGal, Jim & Ken should all have dynos around the same time.. We'll get a good indication of what it can do because all 3 have different levels of mods on their cars.

theboogers

will the sl55 engine also benefit from the 80mm tb? what other adaptions will it need. thanks

vrus

SL55, CL55, CLS55, E55 all share the same engine and all benefit from the same upgrades (for the most part). The TB kit is plug & Play in E55,CL55,SL55.. I havent found the schematics for CLS55 to verify wiring but it wouldnt be too hard once someone with a CLS steps up.

I should have my car back tomorrow with the new TB and coated headers installed. I spoke with my tech briefly today and he ran into no major problems with the TB install. I plan to head to the track very soon to see if my investment has paid off.
