Thread: IRB Developments Td5 Dual/Two Channel Turbo Booster Box adjustable tuning instructio?

I'm currently have intermittent issues with the vehicle including surging and power cut off (suspected due to over boosting) so am trying to determine if the fault is the MAF or Turbo Booster Box is faulty or requiring adjustment.

Nanocom Evolution spat out the following when I read the codes yesterday (it's been a long time since I've pulled them):



Todays code read:



On the drive home today I pulled over while it was underpowered and disconnected the MAF sensor which instantly fixed it. Hence why I have narrowed it down to either the MAF or Booster Box.

Cheers. I will try that as well. I have Facebooked and e-mailed them but historically I recall them being very slow to respond hence hoping someone else might have the information...

EDIT: cheers - managed to find him on LR4x4.com Porny - LR4x4 - The Land Rover Forum . I realised before I started searching that his username is probably a bit dodgy to have been searching on the work network... However it wasn't much use as he can't receive messages - his Inbox is probably too full as it looks like he hasn't been active on there since 23 December 2014...


I received a response from Adda, Adrian Fisher, who was working with/for Ian back in the era I purchased and he advises that he is no longer associated with IRB Developments or in contact with Ian so can't help.

> Instructions:
>
> 2 channel adjustable 'Anti Limit Box'
>
> Red - 12volt Ignition live or permanent 12v feed (seperate from any feed into the ECU)
> Black - Earth (good)
>
> Yellow (orange) and white are the channel wires - one is for MAF and one is MAP (as per standard boost box). It doesn't matter which way round (obviously they need to be used as a matched pair).
>
> MAF is pin 11 in the red plug (grey wire, green chaser on post 2002) (one from end of the bottom row)
> MAP is pin 6 in the red plug as per a standard boost box. (middle of the bottom row)
>
> The box is set in a safe setting.
>
> The channel connected to the map sensor will be somewhere close, but the maf sensor channel will need quite a few turns clockwise (usually about 4 turns)
>
> Your are aiming to see around 220kpa on the manifold pressure and 620-630kg/hr on the maf sensor under full throttle acceleration when set correctly. This should also stop you killing MAF's.
>
> MAF sensor must be a genuine part, and at idle it should be reading 57 - 62 kghr
>
> To get the pins out of the ECU plug, remove the white anti back out plate and use a pick or small flat bladed screw driver to release the standard pin - look from the front of the plug (not the wire side) and you will see the small tab holding the original wire in place.
