Previous projects that have paved this ground include work by Arnoud Bordewijk with his Frankenjag (links currently unavailable), and David Woods, with Ropey and an XJ6R (the AJ16 with a supercharger!) transplant.
It's a bit rare to see manual Jaguars post-1970, altogether, in the United States. Something about the US market research lead them to conclude that it wasn't in their interests to have people rowing their own gears.
Me? I'd like a manual Jaguar, myself. Michelle's 240z project has inspired me to want to go down that route, and in the process, I'd like to make a more economical daily driver. The prospect of 11 mpg with the V12 and the increased cost of the 6spd conversion for it (the gearbox alone would cost what this project should cost in total) didn't really get me anywhere with fiscal discussions with my wife, nor my own concerns. Also, the V12 is a bit of a stretch with where development is for FreeEMS, pragmatically-speaking, but it will get there, one day. I also don't want to do certain things 12 times over, at the moment. Quantities add up fast! So, that project is on the back-burner right now.
Parts Overview
* XJ-S 3.6L Sourced (82-92):
- Water Pump
- Radiator & Radiator hoses
- Header tank
- Engine Mounts (everything that mounts between the subframe and the motor)
(Note the engine revision is AJ6)
- ECU
- Engine & Wiring Harness
- Distributor
- Intake manifold
- Source timing ring/trigger wheel from an AJ6
- AJ16 Engine with accessories (retain the CAS, coil on plug setup, and intake for later)
(Note: Stock motor used a MAF)
- Getrag 290
- Rear manual gearbox mount
- Series XJ 2/3 Manual Pedal Box
- WBo2
Two TA cards
The plan:
* Source the XJ-S parts from US and UK wrecking yards (The 3.6 was rare in the US)
* Install an AJ16 motor & Getrag 290 gearbox controlled by an ECU from an XJ40 (which will require using its Dizzy and a 60-3 trigger wheel)
* Get the car stabilized/licensed/usable before continuing with FreeEMS with further usability fixes like harness additions for gauges, etc.
Potential Strategies for AJ16 engine management:
* Hack on EDIS (with a 36-1 trigger wheel) for Spark, FreeEMS for Fuelling
* Determine how Stock Ignition Amp works, workout code / circuits for FreeEMS control + Fuelling
(Original XJ40 motor used MAF.)
or
* Leave XJ40 ECU on for fuelling, Work on Spark via FreeEMS with later coil-on-plug setup & CAS
* Move over to full FreeEMS control via two ECUs for fully-sequential ignition & fueling
Optional:
* Finish development on XJ40 intake manifold, change to X300 manifold & parts
* Merge to one ECU when resources/milestones are available
Longer-Term Possibilities:
* Differential Swap (To limited slip with a different ratio)
* AJ16S (The AJ16 with an Eaton M90 Blower!)
