[urq] Re: 034 EFI installation

[James Bufkin]

My rally car has a 034 EFI IIC system in it as well.
I have  yet to take it to the dyno, and we have only used a narrow band on 
the tuning, but so far the results are very impressive.  Of course Javad 
did the tuning for about 25 minutes in the passenger seat, so that'd be 
about 10 hours of my time.  LOL

I have a LM-1 wideband to install and things should progress from that 
point forward with some concrete data numbers.

The install was pretty straightforward.  There are some troubleshooting 
things that I had to do with could be documented better and I'm going to 
make a page on my website about that.   For instance, there are some things 
to look for in the software and sensors prior to even trying to start the 
car with fuel.   The most important thing is the counting of the teeth on 
the wheel and the registering of the flat spot.  Without that nothing 
works.   So that should be checked first and foremost.   If you get 
reference timing, then the plugs should be sparking in nice smooth 
fashion.  The 034 coils are pretty powerful.  I am still looking for good 
set of plugs which like those coils.   So you should lay out the plugs 
without fuel on the cam cover and have someone watch for spark on each plug 
in a nice smooth pattern.   Once you have spark and timing on cranking, the 
injectors can be turned on and fuel added til the car catches.  The cold 
start pulses in 034 can actually make this pretty painless and if you have 
good spark and timing, it'll go pretty quick.

Also the clarification of the pins on the Audi sensors would be useful to 
many people.  For instance the 3 pin count on the factory one window Hall 
sensor, the factory VR sensors, the factory 6 pin TPS.  Having all that 
handy and how it connects to the 034efi system would be useful.

The 034 system would be perfect for Audis if it used the Stock Audi 
Flywheel triggers and a Bosch Air Temp sensor.   Those are two relatively 
small things and not that big a deal.   On the plus side is that it allows 
for custom flywheels.
