30/03/2011 Zeitronix AFR + gadgets

The last week I looked around for an AFR (Air Fuel Ratio) gauge. I PM-ed with some guys local that know alot of Nissans.

Finally decided to order some stuff from America. Why? With a wide-band I get a much better idea how my engine is running compared to a lambda-SR20 (narrow band). So I can see if the engine runs lean, too rich or good. The FJ20E  has no lambda control and with this AFR the engine is well controlled.

So I bought an AFR with gauge.




This has become a Zeitronix, more precisely the ZT-2 with plenty of adjustment / reading possibilities.
The plans are to place an EGT (Exhaust Gas Temperature) gauge to be connected. This is something my S12 doesn't have yet. If you are going to tune it better to have a wideband and EGT sensor, this is the way you see what really happens. If you only have a wideband, you see only if the engine runs rich or lean. What you see is how hot or cold the exhaust and that is important, especially in turbo area. Keeping in mind the future plans, being a turbo on the FJ20, this is a logical choice.


I also have been thinking of a Apexi SAFC II.  Skipped this plan quickly because  the SAFC does not work on the current engine. This is because the FJ20E has no  0-5 volt throttle sensor. There is only open or closed and there are no intermediate steps.  The Apexi has been referred to the fridge. Not as long as into the freezer for the project should not be that long.

What are the plans?

short term [/ i] [/ b]
Compression test and spark plugs replaced (The Nissan S12 workshop manual book
BPRS7ES BPRS6ES or-11-11).
Check the fuel pump and fuel pressure.

Slightly less short term [/ i] [/ b]
If the Zeitronix  stuff arrives have that built in.

What do we monitor?
- Oil temperature
- Exhaust gas temperature
- Fuel pressure
- Water temperature
- AFR

And what have we finally bought?
• Zeitronix Zt-2 + LCD Display Bundle in Black
• Fluid Temperature Sensor (1/8th NPT) 2x
• 2x 1/8th NPT Bung
• Exhaust Gas Temperature Probe
• Pressure Sensor (150 PSI / 10 Bar)
• Oxygen Sensor Bung
• Zeitronix Decal

The ZT-2 has arrived. New tyres have been put on the rims (Falken ZIEX 912) and I have bought some new spark plugs.
I am looking for some new discs and pads. Probably hawk pads and OE replacement discs. Thanks for the links Nils (Spec)

The car has been taxated today, so this way its good insured in case something happens to it.
I took the car for a drive afterwards and Its handling better and better. The rear shocks (right one was leeking), front ball joints and tyres have been replaced.

I have also found a document from 1995 where the car has done 177.xxx KMs. So the last 15 years the car has been driven less than 10.000km.

The PU bushes I have ordered are on the way. Coilovers next year so plans are there.

The Zeitronics will probably be built in end of this month.

I went to a Nissan meeting today (yesterday/sunday) and took the car for a longer drive. Like 1 hour.
Got a good response to the car, even thumbs up from a biker on the freeway

Afterwards I went to a Nissan enthousiast who also has a silvia (S110) and we did a compression test on the engine. All 4 cylinders are around the 11.5 so thats all good. Only I wonder about the FJ20 rattle. I will post a video and a topic later.

Car is doing much better, new rear shocks and tyres do the S12 good.

Sweet!
I keep my car cleaner then my room
Fuck you then, I'll take my movies, box of chocolates, bottle of wine and chloroform somewhere else.
Adding an SSD to that is kinda like strapping a 3 inch stainless HKS exhaust on a geo metro.

Hey what is that car to the right of yours in this shot?  Interesting rear end, looks sort of like a Renault...

Wow, I have never seen one before, kinda cool...  but in the color shot it sure does look like someone gave it a swift kick in the ass end.   

Hmmm.

I wonder if it's related to the b210... aussie's name for it was the 120y

Post Merge: [time]08:10:07 AM / 22-Apr-11 [/time]
A quick search on wiki told otherwise...

it's not related to the nissan sunny, but to the nissan cherry... it's the first nissan FWD car ever sold in North America (so it's a FF car).  It's using the famous a12 engine (same as the datsun 1200 and 120y engine)

Monday 27-04-2011

Had a busy weekend, with on monday some time to fix the car.

The FJ20 engine made a strange rattle. I was a bit worried because the common chain rattle is just during start up for a few seconds on a cold engine. In my case it was also during revving like 2000RPM and when starting the engine when it was warm. Decided to replace the chain tensioner for the mazda chain tensioner 395312500A

It was a bit of a puzzle but we managed to replace the tensioner with the modded mazda one.

Some pics






How the FJ20 sounded
http://www.youtube.c...h?v=0_mBaJ4vZEU

and sorted


After that we planned to built in the ZT-2. It is partly done, due to time problems but here is some of it



The rest of it will be build in shortly.

A buddy of mine is going to make a nice cover of poly so the ZT-2 will be on the spot the radio used to be and the radio can be mounted lower.

Afterwards I did a photoshoot with a buddy of mine.





And yesterday I went to the premiere of fast and furious 5. Paul Walker and The Rock come to the movie and did a little speech for us. Cool

Thats all for now folks! To be continued

Did some instalment of the Zeitronics ZT-2.
The fuel pressure is measured now, and the EGT sensor is connected.

Then did some maintence to the car.
- Tie-rods front replaced
- Brake pads front and rear
- Brake fluid refreshed
- LSD oil refreshed
- thermostat replaced
- Cooling system flush and new coolant
- Oil filter replaced

Afterwards decided to wash the car and take it for a spin. And took some pictures.

Look at the beading on the GP. Im getting hungry again.
There was no beading when I brought the car to my buddy.




And last saturday I did a semi-proffesional photo shoot with the S12. Pictures are coming soon, the guy that made the photos needs to do some finishing on the pics.


Next thing to do is getting the car aligned? Dont know if this is the right word.

Anyhow short term to do list is
building in the rest of the ZT2 sensors
taking the car for a spin on the Nordschleife in Germany.

Long term
BC racing coils
FJ20E+T project
And everything what comes between

I update to many times?
