My EFI Conversion so far

[michael tierney]

I started this way too late but i hope to tune it on the road and rolling road it very soon....i just have to get it through the national car test here first which is comming up soon!
I'll give a detailed description of the installation as i go on.....

Good work there cant wait to see the rest

[michael tierney]

in the second pic.......i mounted a hall sensor as a pick up from the mechanical petrol pump eccentric cam........when the lobe is going away from the sensor,cyl no.4 (or renaults no.1...nearest flywheel) is comming up to overlap...meaning its ready for injection.....so we have a sequental starting point!:)

Very clever with the mech fuel pump sensor mounting!

What ecu will you be controlling it all with?

[michael tierney]

i have the adaptronic 420d ECU installed.......i was put wise to the cam lobe by Scoff.....because i had forgotton about it being there in the first place!
there is a PDF Adobe manual included in the download and i would suggest to anyone going to convert their fuel system to READ IT............i didn't read it until recently and it would have saved me alot of bother......so now u know!

[michael tierney]

finally got the boost circuit fitted with a bleed valve....and wired
and i'll be fitting a knock sensor soon..........very important:)

[michael tierney]

more ventilation for my ignitor and coil plus an extra heat sink
fuel pressure reg is from webcom and is adjustable

Is that blue on your water pump pully off the silicon hose?

[michael tierney]

i see what u mean :) no ,i got the pump from a guy who had painted it blue as well as the degasser !!

[michael tierney]

i've decided to go the origional route with my EFI manifolds and also the narrow spray pintle type injectors, the installation is fairly compact.....the throttle cable is tricky but i didn't want to cut it (a good original one is very hard to get)the original pipe work works out well.
i will have to make up some heat shields for the exhaust as the radiation from it will be extreme especially when it glows bright red!

Looks excellent Michael. Keep us up to date.

[michael tierney]

i wasn't thinking when i ordered the black elbow!!

[Fordy]

how well does the cam lobe pickup function?

[michael tierney]

the cam lobe is picked up by a hall sensor(5v from the ecu) , you use it as your no.2 trigger for injection....as far as i can remember the sensor is closest to the lobe just before no1 TDC.....all u want is a small signal as to cam position....then you can go full sequential injection....so it functions very well,Fordy!

[Matt Cole]

Michael where is the can line sensor installed?

[michael tierney]

Michael where is the can line sensor installed?

the cam lobe sensor is mounted where the origional petrol pump used to be.....under no 4 plug on the block you can see a blanking plate with 3 bolts in it
there's a pic of it further back in the thread with the rad fan

Cheers Michael. There's a few rtoc members need your pearls of wisdom and possibly an efi manifold!!;)

Thankyou matt your a star.

Michael you have a pm too.

Cheers guys

Couple more members coming for a manifold Michael! :)

Couple more members coming for a manifold Michael! :)

Well I hope my manifolds are improving membership 😃😃

Well I hope my manifolds are improving membership 😃😃

The last couple have been members so unfortunately not! At least RTOC gets a mention when someone wants your manifold.;)
