Skoda Octavia A7 1.8TFSI 4x4
 

Hi all, is there any wiring diagrams available for topic car ?

Model Year 2014, Engine code - CJSB

Thanks for any help...

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Does this have a two fuel rails, Di and Pi?

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Nice to hear you Richard. It have 2 fuel rails...

Re: Skoda Octavia A7 1.8TFSI 4x4
 

can you tell me the serial number of the controller

Re: Skoda Octavia A7 1.8TFSI 4x4
 

The system you have is a standard HFS4v3.1, not configured from twin-rail. But you can run the system based on boost, would you like me to post a diagram?

Re: Skoda Octavia A7 1.8TFSI 4x4
 

What should i do to run it like it should be ?

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Help me please Richard :(
Should i send board to you, to modify it ?
If yes, just trow me address :)

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Try this one first, the system will track boost instead of twin fuel rail. Some users have difficulties dialling the fuel tracking version. If you are not happy with the delivery, send the controller back to me and I will converted it for you.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Great, thank you. Will see how it will work.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

And one question more, should i change any jumper configuration on board?
I see from picture above - P/IR zeroed out for 100% boost control and MPS trigger set on... Any other changes to other side of the board?
Thanks.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Is this correct address to send controller back? In case...

ERL Ltd
Iroko House
Bolney Ave. Peacehaven
East Sussex BN10 8HF
England
T: +44 1273 581007
F: +44 1273 581555

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Yes, this is the correct address. I would really think twice before going for the twin fuel rail set up, it is quite tricky. There are substantial modifications onto the circuit board, it is not easily reversible.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

I would try it as it is I need a base line to help you from. If deem necessary.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Got it! Thank you for helping me ;)

In transit

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Hello, is there any update ?

Re: Skoda Octavia A7 1.8TFSI 4x4
 

I believe it has arrived.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Almost 3 weeks ago :rolleyes:

Re: Skoda Octavia A7 1.8TFSI 4x4
 

It may be but I can not service one customer immediately, I have many other duties.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Have you tried the progressive boost mode before sending the unit back? I have spent a great deal of time making this unique diagram for me.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Please note once this controller is re-configured, it cannot be reversed. Please confirm that is your wish.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Great to hear you back, i just wanted you to confirm acceptance of package...

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Yeah, i've sent you long email with all steps that i did ... It seems smth wrong with board, as it didnt light up the gauge, but still can do sys.test via jumpers ...
And i think we need to check the wiring diagram for this car, its like Pin 6 is not IGN Sw 12V, as it powers on when i open door ...

Re: Skoda Octavia A7 1.8TFSI 4x4
 

If conversion will work for this car IDC as mentioned, i cant see why we should not go this way. Is there any other hidden things i need to know ?

Re: Skoda Octavia A7 1.8TFSI 4x4
 

it is completely up to you. We have a number of users unable to cope with balancing the two IDC signals from the two rails, once the factoring setting is twiddled. I am sure you like the challenge?

Re: Skoda Octavia A7 1.8TFSI 4x4
 

:) Is there any available manuals, how to balancing two IDC signals, i start to realize this is not exactly the same as single signal ?!

Re: Skoda Octavia A7 1.8TFSI 4x4
 

There isn't a manual for this. But is quiote simpole, you use the P/I-R trimmer to bias the two signals. Some modifications change the size of the port fuel injectors so the system needs to be trimmed.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Since we have both stock injectors, it seems there should be no problem :)
So let's go with this challenge ))))

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Hello Richard. Is there any update? =)

Re: Skoda Octavia A7 1.8TFSI 4x4
 

I am going to send you two controllers, one withe modifications and other not. I like to try them both and let me know. Please email me your latest address and how you want the controllers shipped.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Wow, thank you for this. Did not even think that i will get 2 controllers :)
I will try them both for sure. Just tell me how much do i owe you for converting/fixing controller. And what was broken there ?

P.S. Sent e-mail with address to richard at aquamist dot co dot uk.

Re: Skoda Octavia A7 1.8TFSI 4x4
 

Conditions:

1. I like to have one back if you are not using it.
2. You pay for the shipping of two controlers to Kazakhstan
