Astra Coupe Turbo 273bhp, but 25bhp less power with WI.

The car does not feel like it is losing power with water injection on anymore. It was difficult to tell before if there was a difference (after the jet was moved), I think this may have been down to the bad earth problem I had which may have restricted the power to the fuel pump - as the car generally felt slower anyway. (I thought I was getting used to it!).

It is a pity I didn't bring my camera with me - could I have a copy of the photos you took please? The installation is almost hillariously neat - I'm very pleased with it.

I look forward to Friday. I'll be leaving Falmer at 4pm, so should be with you by 4.30pm.

Mike,

I will put everything onto a CD fior Friday, from day1.

Friday:
It won't take long to plud the unit in. We need to find a place to tempaorary mount it so that you can see what is going on. I will set the unit for zero convert but you can still see the the lights flashing on and off.

I will certainly try to get thing moving as quickly as possible. I would allow the unit to run a week to see if every part is working correctly before booking a RR session.

If the unit is effective, I will make a few more prototypes.

Richard - I got your email. See you tomorrow.

Excellent, can I put my name down for beta testing :razz:

yes, of course.

Richard - it all seems to be functioning correctly. The WI won't come on any lower than 3.8v at the air flow meter, so I guess this is the lowest flow at which the 10psi can be gained. Lambda seems spot on too.

Thanks for the MAF information. I guess it means when the MAF reads 3.8V, the boost is at 13psi?
I can't remember at what boost the WI triggers. Can you?

I have a few pictures here I took a few days ago.

[MikeWarner]

10psi.

Thanks Mike.

The MAF threshold is between 2.6V to 4.85 volts.
Each click of the trreshold potentiometer is about 0.11V.

11 clicks will arrive at the WI triggering point (3.8V). If you have a moment, could you advance the threshold potentiometer by 10 clicks (not 11), if things work as intended, the yollow led will come on almost immediately after the MAF converter is enabled by the system1s WI.

Things are looking good.

Richard - I thought the threshold was between 3 and 5v. It takes 8 clicks to get the lowest voltage the WI triggers with.
