update: Haltech is in, wiring harness pretty much replaced, Dumb ignitor in, wideband sensor connected; so it should run eh!
well after the down load of a map and a few settings and a month long search of the internet for the reason why it was running very erratically.
So back to basics: Have you searched for the timing settings for a Zetec 1.8? They do not exist. It would have been quicker to pull the engine and see where the crank sensor gap was wrt the top dead centre. I have now found a friend with a camera on a stick so I can shove that down the crank sensor and find out for myself..
The only data about a zetec timing is pull the cam cover slide in the 5mm locating plate and there you go. I have had people question my logic... One even queried if anyone still used a timing light. someone else said why cant I find the timing mark on the pulley etc....
Someone else said that the Phase three engine, according to the Haltec data page is probably a five tooth sensor... I looked through the cam sensor port and it is definitely a single lump of steel rotating around the shaft. The 5 tooth must be for the Variable cam timing system... but that is not written anywhere.
Anyway. I can get it to run; I set the timing to 10 btdc on the Hatech. Then I set it up so that the timing was lined up to the ridiculously place crank case webbing "mark" and it was 82 degrees. Then, after trying to start it, it was spluttering and farting so I added 360 degrees and it was a bit better. Then I could not get it to start. It was definitely rich, so I decided that I should check timing again, NO SPARK... so I pulled the plugs for about the 20th tim, They were a bit sooty... Connected for new plugs to the harness and tested the firing. bingo... I was flabbergasted that spark plugs with a bit of soot on them would stop the engine firing.
Cleaned the plugs and got a spark.
Eventually I got the engine to fire. It raced to about 3500 and eventually started to clear itself and do a bit of self tuning. eventually got down to about 900 rpm and stalled. Needed me to ride the pedal a bit to keep it above 1200 or it was stalling.
Then it just wouldn't start again... Rinse and repeat...
More frustration. I have even gone back to checking most of the primary settings and wire connections, even undone a number of the nice wiring bits to find out why I was getting NO Home sensor reading (cam Sensor)
Contacted Haltech a couple of times, as I wanted to know why the home sensor wire shows up as an unassigned wire. It just does... A friend said that this was unusual until he checked his Haltech running 4AGE and guess what, it is unassigned. They did say that they could understand why I was confused.
Also asked them about displaying the home sensor reading on the cam sensor... Definitely possible apparently ...well until
" Both of these errors point towards the ECU not receiving a signal from your Cam sensor.
You can use the oscilloscope to see the raw voltage from the cam sensor in the same way that you did it for the crank sensor, just have it display the Home Voltage and see if there is a waveform present when you crank the engine."
My reply: "Thanks but there is NO Home voltage output value available to input into the Oscilloscope."
OH: "This means you're using a reluctor sensor on a single connector ECU therefore you'll need to be looking at the Home Input State. The Home Input State will change when the ECU detects a tooth based on the settings you've provided it. If there is no change in the Home Input State, then either the ECU isn't receiving a signal, or your settings are preventing it from detecting the signal"
I connected a multimeter to the Cam sensor output and can get a voltage... albeit variable as expected but difficult to measure as the multimeter is not an oscilloscope.
ANYHOW: You can read my frustration. Today I plugged the computer back in. check the timing, well tried to. No Spark. Plugs were clean. Rechecked the other plugs, no spark, checked the harness plugs. now a spark is present again. replaced plugs, checked timing again, turned on the injectors. no fire... just a couple of random backfires.
Shut the door and watch BATHURST PRACTICE!!!
Sunday! well see what I get to tomorrow.
This link should prove that at least it was running albeit a bit rich.
