Installing TMC Tuning Box - 1.4 TSi GUIDE

VRSLOZ · Aug 14, 2011

Tools/Parts needed :

Torx screwdriver (T30)
Large Flat head screwdriver
Small Flat head screwdriver
Pair of latex gloves
TMC Tuning Box Kit

Car used :

2011 MK2 Skoda Fabia vRS 1.4TSi

Time needed :

About 20 minutes but allow a bit more

Difficulty :

3/5 - A couple of plugs are fiddly

**MAKE SURE THE ENGINE IS COLD WHEN INSTALLING OTHERWISE YOU COULD END UP GETTING BURNT**

You'll have this to start with :

Engine bay should look like this :

First thing you will need to do is remove the engine cover, this is done by gently but firmly lifting the bottom left and right corner then then pulling the cover towards you :

The three plugs that need to change :

Turbo boost pressure sensor plug

Camshaft sensor plug

Manifold air pressure sensor plug

Let's start with the turbo boost pressure sensor plug, you will need to remove the turbo air intake pipe by removing the below Torx screws (some already removed but locations shown) :

On the top end once you remove the two torx screws you will have to lift off the plate helps hold the pipes together. Now you will need to wriggle the pipe while turning it towards the engine so it becomes loose like so :

Now that's out the way you can get to the turbo boost pressure sensor plug, you will need to take the large flat head screwdriver and use it to remove the clip. This should then allow the plug to push off :

Now connect the turbo boost pressure sensor plug on the TMC harness to where the OEM one was and connect the OEM plug to the other connector on the harness :

You then have to refit the turbo air intake pipe by using the steps above in reverse. You should be left with :

Now move onto the camshaft sensor plug, you will need to take your large flat head screwdriver and unclip it :

Now connect the plug on the TMC harness for the camshaft sensor to the OEM port and the OEM plug to the TMC harness.

Last plug now, the manifold air pressure sensor plug. Much like the camshaft sensor plug you will need to unclip it with the large flat head screwdriver :

Connect the plug on the TMC harness to the manifold air pressure sensor port and the OEM plug to the TMC harness.

You then need to connect up the tuning box itself, you do this by pushing in the plug into the box :

Then pushing down on the purple securing pin :

Should be left with this :

You can now tweek the setting to which one you would like to run, 0 being the lowest power to 9 being most power, you will need to use the small flat head screwdriver :

At this point turn on the car to make sure no faults come up, if they do it might be best to remove the tuning box and investigate further.

Time to tidy it up and secure the tuning box. I cable tied the cables (provided in the TMC kit) to the air intake pipe leading the airbox and cable tied the tuning box to the car :

(I will be securing this more at some point today)

Finally we have to put on the engine cover back on, push the bung at the top of the cover into the slot for it and then push down the bottom left and right corner :

Step back, pat yourself on the back and go and get yourself a nice cuppa............or take the car out to feel the extra ooommpphh!

Thanks mate, it feels a lot quicker through the midrange, feels like a lot more torq. I got bought the box, remap is still on the cards

I'm sure I read somewhere that with these adjustable map tuning boxes, you have to start with a low tune setting and then progressivly work your way up to the higher tune settings so as not to provoke the ECU to enter limp home mode. Did you do this or is it a load of bollox? lol

To be honest it's been run on setting 6 & 7 and had no problems so far **TOUCH WOOD**

Saw your VRS the other week in the evening. Do you play golf or go to the gym at Chesfield??

The VRS looked great by the way! And nice and clean too! :lol:

VRSLOZ · Sep 30, 2011

Edward101 · Sep 30, 2011

Might go down there this evening well when its still light and practice a bit of golf, you may see my car down there sometimes go there a fair bit

good guide loz, hope your enjoying your skud

Only problem with the ibiza is you have to take your driver and woods out as they dont fit in the boot!! irons are fine tho lmao

Nutkin · Jan 13, 2012

I wonder if a group buy could be arranged, as this is a great solution for those who want to try and hide there extra power from the warranty man

VRSLOZ · Jan 13, 2012

If anyone is interested in that I can speak with TMC.

Obviously I don't want to go against site rules on anything so if I am tredding on toes let me know

Happens with the fabia as well. The boot is actually wide enough to fit the clubs in, but you cant get them through the lip of the boot in the first place. I just fold a rear seat down tbh

Did this improve fuel economy? With maps on the car driven sensibly mpg can improve I heard. Have you got any definate power figures yet?
