biggrin CFI to MPI Conversion Complete!!!!

Well i have finally got around to convert my EA falcon from CFI to MPI. I got the parts off sundeep. The car hammers now!!!!, best bang for your buck mod you could do. Took 2 full days to get everything right, reused my CFI dizzy as the MPI one had a worn bush and was causing a rough idle. Runs perfect and also changed the injector power supply to feed off the ECU relay. I found when using the fuel pump relay to power the injectors the car turned over a few times before start as opposed to the correct way from the ECU relay which starts first turn every time. Here is a pic of the finished product.

It wasn't easy but not impossible, lost a bit of bark off the hands. You need a good set of tools and all the right parts. A timing light also comes in handy. All up with the parts, new gaskets and heater hoses it came in around $300. Which isn't bad for a 20kw gain.

Just started the car this morning at 4degrees ambient temp and it started first turn and idled so perfect I couldn't beleive it. The old CFI setup would always stall, turn over a few times then idle rough.

Cheers Luke (jjj)

Re: CFI to MPI Conversion Complete!!!!

Congratulations Luke, an extremely worthwhile upgrade. Not only do you gain the benefits that you mentioned, but a whole world of possibilities for future upgrades.

I didn't realise CFI had the same starting characteristics as carburettors. My MPI cars start perfectly no matter what the weather, whereas starting my dad's carby Toyota in the cold is a huge effort.

Re: CFI to MPI Conversion Complete!!!!

Ahhh sick mate! That's good stuff Luke.

My car had the same problem as yours before we converted to MPI. You would have to crank it over like 4 times then stop, then another 2 and it would start but take a few seconds to idle properly. With MPI it starts first time, every time no matter what. Now it's on gas it takes a little more effort to wake it up in the mornings but 108km from $5 isn't bad either

Sorry about the dizzy :o( Seems you and I both got ripped.

Re: CFI to MPI Conversion Complete!!!!

Congrats, it's a very worthwhile mod even if you leave it stock. By the way, my car always started perfect with CFI, I don't understand what you guys are on about?
