I have a pre-HE v12 jaguar that was converted to propane once in it's life. I converted it back to fuel injection using two pre-he parts cars and had a brand new wiring harness built but it never ran right. I'm tired of dealing with D-jet on both my Mercedes and Jaguar cars. Has anyone converted a pre HE car to a stand alone ECU? I'm looking at ECU masters website and it seems like a solid kit.

 

There are various put-together options, but the only complete pre-programmed full system replacment I'm aware of comes form Ole Mobeck.

try Emerald in the UK, I think they do one for the pre HE, but not yet the HE. They have a good reputation and are not stupid expensive.

my stande-alone ECU on my 1978 XJS V12! pic. the actual system is SDSEFI.com , crane the ignition system!

hand held programmer, beside old cell phone,comparison only!

under hood , ECU gold box! i read where Crane was sold to another company,sorry dont know who!

view under hood, Crane cams and electronics, is a good standealone , but low sales was discontinued!

no longer in busness ,Crane electronics , was in Florida, it is a fairly good setup, time consuming tuning it tho, BUT still runs and drives great!

 

Thank you! this is fantastic. I will call the ECU master rep and see if a Jaguar v12 has been done.
