Converting from Chrysler to EZK ignition on your late model 240

It's not bad at all. You're only dealing with like half a dozen wires plus the wires for the sensors, but those are impossible to mix up. I did the swap a couple of weeks ago on my 85 240 wagon. Worked perfectly and was way easier than I thought it would be. Idles so nice now.
 
what about splicing the harness? should this cause any problems? any electrical interferance?
reason I ask is I didnt have much time and just cut the connector off with about 14 inches of wire harness with it... has anybody done this or should I take my time to remove a complete ezk harness?
 
Just got mine running!
I used an 004 distributor (003 DID NOT WORK as stated in an earlier response) I also used a 740ti ezk box. I was concerned with whether the turbo spark curve would suit the N/A engine, but it works great!
Thanks for the great write up!
...Now to put the complete fuel and spark computers and harnesses in the old 242. Wish me luck!
 
Thanks for all the info Nick. I have a 1987 240 dl and and have a wrecked 1988 740t that is going to be an engine doner. I'll also take all the EZK ignition and follow your steps. One question. I have a head mounted distributor on the 740t engine. I know it will not fit due to the firewall. I was planning to take the block mount 004 out of my old b230f engine as well as the required shaft to drive it. I have seen articles where this has been done on a 740 and where they did'nt even bother to remove the old one. As long as my connections are Bosch, do you think this will work for me, or is the EZK picky about the distributor type?

Thanks
 
One of my first posts here....

So I have an 82 242 B21F-MPG with K-Jet and Chrysler ignition and I would love to get rid of that rough idle. Will this guide work for me having K-Jet? I tried searching but couldn't really figure this out.... this guide says it will only work for LH cars... will someone please let me know? My mechanic wants ~300 bones for the conversion but I'm slowly getting more adventurous and am thinking about tackling this one myself.

Thanks

hey guys. i'm trying to find some diagrams, but all the links are dead now. can anybody point me in the right direction? i want to start this swap (on my 87 245 before i +t) by this weekend. any help would be great, thanx
 
did ANY 240s come with the harness and ecu u need? or does it have to come out of a 740? im thinking doing this swap will stop my car from hitting a rev limiter at 2500 and when i connect the hose to the chrysler box it doesnt run good
 
Just curious does anyone have the original images nick had on the site, the links are dead.

as far as what cars came with what ive been doing my research. my 83 242 n/a is lh 2.2. the n/a 240's kept going until early 85 with 2.2. then in 86 i believe switched to 2.4. in late 89 they then switched to lh 3.1 on the manual cars and kept 2.4 on the auto cars. the 3.1 back to 2.4 is pretty basic, just need to add two wires from the ecu and the proper amm and tps. the ezk is a direct swap, but the turbo 740 ecu can be somewhat hard to find years 90 to 92. there are a few other years that work but they have different configs, with egr and what not. the important part is turbo lh 2.4. must be a turbo ecu.

I believe you're mistaken. The '83-'84 cars were LH 2.0, the '85 (with the B230F engine) through '88's were LH 2.4 and starting with the '89 model, they switched to LH 2.4.

I should mention that I have seen at least one '84 model that had a B230F in it (instead of the B23F) and LH 2.2.

fixed, otherwise you are correct sir.
 
hello all, so thanks to the plethora of information here on turbobricks i succesfully +t'd my 85 245. after which i then threw in some orange tops and an ecu from an 89 760. i also pulled the icu loom and computer from the same car. so after being not so pleased with the car considering having stock spark and turbo fuel i can only push the gas pedal about an inch past the point where pressure starts or it bogs down and falls flat on its face ( not so fun in an intersection.) i pulled the yellow wire with a red stipe soldered it to the yellow wire coming from the icu harness and connected it to pin 24 of the ecu.. the red and black wire i connected to pin 12 a blue and white wire. the dizzy is hooked up, the blue wire from the harness is on the positive coil terminal as well as the blue wire from the powerstage. there is only one thick red and white wire coming from my powerstage and it is attached to the negative coil terminal. the brown wire between the powerstage and the icu is t'd to the body. and the orange and yellow wire with a grey stripe are attatched to the connector by the iac.yet it wont start.. so after studying up on the current pages about this ignition swap i started to feel froggy so i leapt. just endless cranking.as soon as i turn the key my tach needle twitches but that it.. no movement during cranking whatsoever... i have no formal experience and everything i know about cars my volvo has taught me. i know the icu is good i pulled it from a running car.. i really need some help with this one please
 
What about the vacuum hose on the chrysler ignition box? Is there a corresponding vacuum plug on the EZK box? Right now I just have a LH 2.4 ICU and it has none.
