wi led on
 

hi just had my audi tt 1.8t track car fitted with big turbo etc now 450bhp.
the wi led comes on when throttling up.
is this normal please.

Re: wi led on
 

just some more testing and the water level lamp comes on as well.
i checked the nozzle and the line and that appears to be ok.
the car was 320bhp, its only done this since the engine upgrade.
ive tried adjusting both the wl and wh adjusters and it doesn't seem to make a great deal of difference, the nozzle size is 0.8 is it that it just needs a bigger nozzle.

Re: wi led on
 

If you are using a small nozzle, you need to solder link 1&2 so the flow sensor is more sensitive. You nozzle is too small for 450 hp.

Is the 1.8tt is direct injection engine? if it is what is the engine code. You might also need to set the IDC prescaler to x2.5.

Which version of HFS3 do you have? Or post the serial number here.

Re: wi led on
 

I think the engine code is not relevant as it's not standard,it's bored to a 2ltr with forged rods pistons etc, the head has been ported ect.
The block started as bam and cylinder head agu.
Injectors are in the inlet manifold (750cc)
What size would you suggest for injector as a starting point.

The fuel injectors are not DI?

Re: wi led on
 

I'll get the serial no and get back to you.
What size jet do you think is a good starting point for this bhp
Thanks for your help.
Cheers hugh

Re: wi led on
 

1.5cc/hp for M50:W50 0.8+0.9mm jet
2cc/hp for 100% methanol 0.9+1.0mm jet

Based on the standard jets comes with the kit

A bit more info whilst I wait for injector info from my engine tuner.
I've fitted a 1.2nozzel checked the lines etc and turned the ids trim up slightly and now the water leval light doesn't come on but the water injection light does come on as injection
Starts.the pump is activated during this time.
The serial number is 101969.
Cheers Hugh.

Re: wi led on
 

Finally I have the injector details.
The injector size are 830 and the duty cycle is
Max 70%

Can you link FDC and tell me how many bars you can see at WOT.

Try the x1.5 IDC scaler if the gauge does not show full bars.
