Here is a blow by blow description of the the EFI retrofit into FAT265
This will be updated as changed occur. ( Last update 31 July 2004 )

To save you scrolling down to what you wanna read here is some quick links re the EFI section.

IGNITION

FUEL PUMPS

INJECTION / MANIFOLDS

COMPUTER / ECM / SOFTWARE

OTHER EFI RELATED STUFF I HAVE DONE

 

The EFI Computer / ECM

Computer is the common Delco 1227808 or 808 for short
unit found in the VN/VP commodore / Lexon. Also found in the JD Camira
After Years of research mainly at DIY-EFI website I decided to purchase Kalmaker
wiring loom is from a Camira it also had a nice fuse/relay box that
I used It was cheeper then crumble door looms.

Ignition Module & Dizzy

I used a 8 Pin GM HEI module commonly found in chevs and also in
Australian 4 Cylinder Camira's :)  I then used a nobody wants them ELB dizzy
as they have no weights on Vac advance perfect for EFI
and interfaces directly to HEI module.

HEI Coil

The Coil is from the JD/JE delco Injected Camira same as most chev's in the states most likely the exact same coil.

Fuse's Map & Ignition Module

The Ignition module form the JD/JE Camira is mounted on the firewall on a large lump of alluminumn map sensor bracket i used 2 cut down pc block off plates found on the back of your computer all i had at the time.

Coolant Temperature Sensor ( Started & Finished 6-Jan-03 )

You need 2 water temp senders. One for the Dash & one for the ECM.
I wanted to have my heater working so instead of going the easy weay
I made up a adapter using 4 fittings I got the parts from Purple Pig cost about $25
All put together the creative this master piece. Isn't it pretty !. big pic click here



Fuel Pressure Gauge

Big Lump of alloy A fuel hose barb or 2
Taps and drill VDO oil pressure sender
Cost about $50 for the tap's and alloy
VDO said it won't blow up I hope so !!!

Fuel System

Facet Low pressure Fuel pump feeds the surge tank. I got this from Australian Auto Accessories
Almost any EFI pump is the same as VL Turbo.. Don't believe me.. ! look at the bosch part numbers thay are mostly all the same. Ok some are larger but in general you don't need to pay big bucks ( bosch part number and flow figures wil follow shortly )

Click Here for a big pic of the main EFI filter I think the bracked is either off a JE camira or a VK commodore I can't remember as i have stolen lots of parts of both of there cars :)


Throttle Body Experiment 1

I got some more alloy and drilled some holes in it to make a adapter plate to run a early Ford EA single point throttle body plan was to emulate a stock 2 barrel carby. it fits perfectly.
But this is only until the Manifold and Extracters below are made to suit. Runs well although this throttle body is only larger then a stock carter and also about the same size as a 350 holley.. So it has its limitations.

Throttle Body Experiment 2

I got holley 670 Pro-Jection EFI throttle body from ebay just the other day it will arrive in the mail in a few days ( today is 31 july 2004 ) so I want to bolt this up in the next few weeks once i sort a adapter. This unit apart from its larger capacity also has one great feature that I plan on using.
IAC ( Idle air control ) basically for those into EFI the computer controls the idle speed and choke. The holley system uses a GM IAC so it will wire direct to the Delco/Gm Kalmaker EFI system Im running. The ford EA system doesnt have this option. I will update on how it all goes once i get the thing. Holley TBI


Multipoint Experiment 1

EF / EL ford 6 inlet manifold and tripple weber manifold.
Soon to be welded together.. they almost line up.. sweet..
I can use the standard EF fuel rail aswell..
**** PROGRESS
I have just visited a profile cutter yesterday ( 30 july 2004 ) and im getting 2 sets of flanges made from mild steel so I can weld up a adapter so that i will be able to bolt up the ford manifold to the weber manifold without modifying anything.. This makes it easier and we are looking at selling these adapters so if your interested check here for updates.

Tripple Trouble

Just a passing thought.. well for $15 I got 3 ford F100 or F150 throttle bodies from the balarrat swap meet one year.. I may never use them but for the price why not.. I think I got 4 just incase anyone with a v8 gets excited.
** ON HOLD Until the ef setup is done
A note to people that wanna do it themself and not wanting to spend big $$$ this option is way cheap !!!! Ok you got2 find these f150 bodies but I have seen boxes of these for $5 i should of got the entire box !!! :(

Inlet System

EF / EL inlet manifold and tripple weber manifold.
Ssoon to be welded together.. they almost line up.. sweet..
I can use the standard EF fuel rail aswell..

Knock Sensor

Commodore V6 knock Sensor and a piece of alloy
We will see if it works ????????..

Thermo Fans

I got them from some Pergeot piece of crap.. 2 of them cost me nothing.
some more alloy bolts crap etc.. All controlled by the ECU


Testing Testing Attention Please

Me playing on the bench at work ( Im a Electronic's Engineer.. )
Bench testing a Knock sensor amoung other things Drink HAIG and COKe..Buuuuuuuuuuuuuuuuuuuuuurp.

Ignition Woes Possile fix 1

I have been having some missing problems at idle and have been trying to work our what is causing this. After alot of research on the web i have a few possible causes.. Since I have upgraded the ignition to HEI / EFI I noticed a few articles about cross fire in the dizzy from one cylinder to another.. The closest article I have fould was a HEI upgrade for a Jeep 6 Cyl from standard to HEI see article. Basically a largerspace between cylinders is needed to stop closs fire because of the much larger spark voltage..

Ignition Woes Possile fix 2

Because my car has been in the garage for so long its getting often start ups and idling for a long time the plugs look a but black so we may have miss fire purely because of stuffed plugs.. I purchased a new set yesterday and will try them this week.. If I still have a missfire I will replace the HEI coil with standard coil triggered by ignition module and see what happens then ( possibly cross fire as stated above ) I purchased a set of Bosch W8DC plugs the standard plugs for a hemi and also the standard plugs for he JE camira ( luck ) Although I have noticed that most later model cars like for example FORD XE to XF ( XF HEI ) use a different plug.. I have to look but i don't thin the 2-3mm longer plug for the XF will pit the piston on the hemi.. this plug is used in almost all of the late model 6 Cyl fords now.. so i guess there was a change for a reason..

Ignition Woes Possile fix 3

Leads.. They are brand new performace lead but I will need to check to see if they are actually compatible with HEI i will be pissed off if they are not.. and they are brand new and not used

Ignition Woes Possile fix 4 ( thanks gmh265 at performaceforums.com )

It has been suggested that the polarity of the wired that go from the dizzy to the ignition module maybe reversed. Well this is possible as i have changed them before but never really knew what way was correct after all they never came out factory so there isn't any wiring diagrams for them.. GMH265 at performace forums mentioned he had this problem so atleast I know for a fact another hemi owner has had problems so its more important then i though after all.. It seems to run either way but I get a backfire when i rev it so maybe its just a matter of swapping the wires..

Ignition Woes Possile fix 4

Some time ago I emailed fome chap that had put delco EFI on a KE25 Corolla he also used the same camira HEI ignition module and said he has all sorts of problems based on the length of the wire between the module and the dizzy ( after all they were sugosed to be mounted inside the dizzy not on the firewayy like where i have it.. I wil try everything else first then if not i wil have to move it ( some how ).

New Dizzy Maybe ( ReBorn VK carby model )

I have been hearing rumors that the VK commodore dizzy fits into the hemi block.. Had to try for myself so I went down to my local pick and pull and got a VK carby EST dizzy complete with rotor cap and leads i stole off a ford EA or something as the VK ones were too short.. the guy at the counter didn't care all up $39 oh $1 entry so a cool 40 smackers ! not bad

first up it looked like it would just go straight in but after i got home i seel the length is out by about 5mm so i went about destroying I mean dismantling it along with destroying a old hemi dizzy i had lying about. I will update some pics soon but after some stuffing around I can use the shaft from the hemi and with a grind here and a weld there it all looks possible. some chap from a forum mopar market or performanceforums has some this ended up cutting and welding so atleast i know its possible. I still need the top part from the XF ford dizzy which is compatible with the delco VNV8 ignition module. I know this cause i done it before on my mates XEGhia6 I couldn't manage to get the dizzy out of the car on my lunch break so I will have to bring some open enders to work and try again tomorrow maybe if its not raining.

I FIXED IT !!!!!!!!!!!!!!!!!!!!

After all the troubles i had the Ref angle set incorrecly on Kalmaker I did know i needed to have it set to 10 deg but i loaded up another cal that was default of 70 deg and forgot to change it. Even in module mode i had backfire through carby problems these turned out to be carby problems I have since rebuilt the carby and its all perfect..


Coil Pack is the next Project..

I got a old harmonic balancer from a Vn V6 commodore that i have pulled apart to install the timing slots onto the hemi crank. Picture again will follow very soon.. this looks like a very cool upgrade its late 2am i better goto bed. updates soon.. ( 23/11/2003 )
