i know that the 13bt injection works as staged.is it possible the same engine to work properly with 4 injectors jetting all toghether from idle to top end with adjusting the duty cycle as rpm changes.as a conclusion i want to know if it's possible to run a 13bt with l-jetronic pistons managment???

good question, thats sound interesting. So this J tronic thing is a Stand Alone i presume, just for pistons right? in theory I don't see why it wouldn't work, but u might have to relocate the injectors or something.

l-jetronic is a pretty standard factory fuel injection system. i think its made by bosch, you see it on alot of german cars, im not sure who else uses it

L-jetronic is common at piston engines.it manages fuel only,it was very popular at 80's and early 90's.AUDI quattro s1 used it.

it fires all injectors at the same time and jets more as rpm increases also getting signal from afm.and of course it is very cheap.

so what do you think,may i have try?

does the 13bt needs any special intake port timing?

i also thought of using L-jetronic for primary injectors and a Haltech F5 for the secondaries that will come alive after 3800rpm.



please tell me your thoughts.

How cheaqp is it? the price of standalone systems has gone down alot. What are you planning on doing with the car?

we talking for about $200 all(used).i 'm thinking to go around 250rwhp.

250rwhp ??? you can do that easily on stock fuel management with just a reprogrammed stock ecu. i put down around 230rwhp with only 7psi of boost https://www.nopistons.com/forums/pub...IR#>/smile.png

Yeah, I'm with you, but firing all of the injectors together will work. I've seen it done.

there is no point in changing the EMS for 250rwhp

sounds like some good **** to me is it programmable? https://www.nopistons.com/forums/pub...IR#>/wacko.png
