Please help is it possible to put the later motronic system on a L jetronic fitted car

interesting question. must bump this up, I'd like to know too!

Thanks for responding martinse i have posted this topic a number of times on this and other forums but have no replys at all perhaps it cant be done my reason is i would like to use a zone chip and it is a better system to expand on lets hope someone else shows an interest and can share their knowledge J,

i would to know as well , is it L jetronic thats on the early 323is ??
surely its just a case of swapping the bits over , well obviously it aint that simple but u no wot i mean!

Hi Jordano

I had this dilemma recently and was told that it is easier to swap the engine than redo the engine management. It can be done but is a lot of work. It may be worth considering if you have a low mileage engine, if not, look around for one and swap it. The engine swap is a lot easier than you might think.

Hope this helps

Thanks for your ideas everyone it is an early 323i 1985 but it is also an Alpina C2 2.5 with Ljetronic would like to keep the engine but would like to chip it any ideas anyone, J

Any links about injection types on different models?
I have a '90 316i M40. Do I have an L-Jetronic or what?

I have all the pinouts and what where and when for the Jetronic/ motronic swop ( Ians work not mine BTW ) email me if you need it and I'll forward it, not too bad a job TBH.

all post '88 facelift E30s are motronic, 320 was Jetronic pre faclift as were the 4 cyl M10 engined cars.

Hi Ant thanks for your reply it has got me a bit confused, are you saying all i need to do is change the ecu and alter the wireing to change to Motronic do i not require the inlet manifold idle vale and all the other different parts used on the later system J.

to clear this is up a bit...

you'll need the motronic ECU, the loom and sensors and the matching inlet and injectors, front timing cover , crank sensors and pulley to get it all to run, none of which is hard to swop or major Ԛ£Ã”šÃ‚£ from a breakers yard

HTH a bit more

Thanks again Ant that was just the info i needed one more thing then i,m set can i get all this from a 320i 1988 f reg whith motronic J
