Jaguar ECU

Going to start the next big project when I have all the feathers and bones.

So far I have the Emerald K6 ECU and tested it with the provided software.

 

 While I am in there I will also replace the narrow band HEGO (Heated Exhaust Gas Oxygen) sensors with an Inovate 3844 MTXL wide band air/fuel ratio gauge/logger to have the ECU fine tune the mixture.

 

 

Still need:

• 6 ballast resistors for the low impedance injectors. The ECU requires high impedance.
• Three way switch and resistor to dynamically switch between ECU maps.
• Fabricate an extended dash on the transmission tunnel for the AFR gauge, map switch, and idiot lights for low fuel, and radiator fan running.

All it takes is money, time and sweat.

Jaguar dyno run

Took the Jaguar in to my local dyno shop, Excessive Engineering, LLC soon to be renamed to Lugo Motorsports. 2320 Clark St. Suite A11, Apopka, FL.
I Just wanted to get a baseline benchmark before changing the stock ECU (Engine Computer) to an Emerald K6 ECU.

Put on the dynamometer  (rolling road) and did 3 pulls.

1. Found why limited top speed. Getting starved for air.
2. Disconnected MAF (Mass Air Flow) sensor.
3. Replaced 50mm MAF with 75mm MAF.

X axis = RPM x 500       Y axis BHP x 50    dots = FtLb Torque

As seen is this chart, 1st run not so good with a dip in HP between 4000 and 4500 RPM then maxing at 5000 RPM.

Very knowledgeable and helpful. Thanks Dennis.

Jaguar 10 Mile drive

 

Nice sunny day for a drive down some back country roads near home.

Tonneau

New tonneau cover.

Had material left over to cover the center console. Had to take the duct tape off first.

Jaguar project headrest fairing

Layers of bondo and primer, file, sand, do it again, slowly getting there.

Jaguar project headrest

Latest project creating a set of cowl headrests. I first made a paper ellipse and used it as a template for making a cardboard mock up to get the dimensions and shape as close as possible.

Initial framework.

Not out of pop-rivets yet.

More frame work.

Number segments so I don't get too confused.

Frame has taken shape.

Paper templates laid out on sheet of aluminium.

Cut lines, numbers and orientation.

Segments pop-riveted to frame.

Some additional storage space here.

Added hinged door and lock.

Had to get more pop-rivets.

Taking on final shape.

What it will look like on the Jaguar.

Large gap to leave room for tonneau cover.

Rear view.

Another angle.

Pink stuff is bondo filler to hide rivets.

On to priming sanding and painting.

 Need to fabricate the passenger side next. Designed to be removable with 3 bolts and clipped into rag top rear hold down spear.

29th All British Car Show

Wonderful day at the All British Car show in Mead Gardens, Winter Park, Florida. Perfect weather as usual.

Window tag for FF class, British modified.

Display with others in class.

2nd place, peoples choice award.

Once again the longevity award. Same car owned for over 49 years.

Old school GPS prize for longevity.

Overall a very good day.

Jag Joy Ride

Took a little ride in the Jaguar around the block... the long way.

The quick version sped up 7 times. No sound.

The long version with sound.

Jaguar project intake manifold

Finished the intake manifold and reinstalled on the engine. Looks a lot better, but does not change the performance.

Now just a simple matter of putting the bonnet back on and going for a nice long test drive.

Jaguar project update

New 2 ear hub caps for the wire wheels

Longer bolt, lock washer, fender washer, fabricated plate, spacer ring and hub cap

Looking good when done mounting.

Cleaning up the intake manifold.

Pulled the intake manifold to clean up.

Will skip pulling the fuel rail and injectors. This is how you get to them.

I thought it was powder coated, but just painted.

See if I can polish the aluminium and see how it turns out then decide if I want to repaint.

Underside with casting stamps. FB for FBA model and 1993 casting year.

 

I had a bad transmission leak. I pulled the transmission and found it was the bell housing where it mated with the shift rod. Repaired it with epoxy clay and a new gasket fabricated from gasket material. No more leak.

On the road again

On the road again the past few days. Tried making a video with DVR-530 mounted on the deck behind and between the seats. The video is ok, but the wind noise drowns out the engine noise above 40 MPH or so.

About 1/2 hour before sunset.
I should have updated this earlier with the tunnel and seats back in.

The center console works out nicely. Just the right height. Now have to get on with finishing the interior and getting rid of the temporary duct tape over the foam on the console.

T9 transmission install

Ready to receive the transmission.

Installed, now the rest of the stuff to connect it all together.

Drive shaft connected, still a lot of stuff to reconnect. Hall effect sensor for speedometer, back up light switch, and double check all the bolts for proper torque.

Transmission and drive shaft tunnels, seats and seat belts. While I am at it, installing an idiot light for low fuel, and another indicator for when the radiator fan is running.
