What a fantastic build! Congrats!

I have a E12 518i and the K-Jetronic system is acting up. The K-Jetronic is almost all-mechanical, but the tolerances are very fine, so it makes it impossible for the “user” to fiddle.

This is just what I need. If I may ask, what was your total spend?

Again, congrats on a job well done!

Your blog has been invaluable in planning my megasquirted 02 project but I’ve got a few questions. I know this post is pretty old but I’d really appreciate the help. Maybe you could email me?

What cold air intake tube and filter did you use? Those things are damn expensive and I want to make sure I get one that fits the rubber elbow on the 325i TB. I don’t want one that expects me to have a MAF sensor in line with it.

What did you do with the crank case vent? did you put a PCV valve on it and hook it up to the throttle body or just let that tube hang or something?

Thanks!

Bozo, see page 4 of the article.

I also plan to use the fiddle circuit to drive a Bosch IAC instead of the stock E30 Valve. I hope you write-up your experience so I can learn from your experience.

Great work, very inspiring.

“Hey Mark,

Honestly, I don’t recall having to make any decisions at the wiring stage. I used the Megasquirt relay board kit . I think that the instructions told me how to wire the controller to the board.

Once you are up and running, you set up the firing order and injector control scheme that you want to use in Megatune.

I hope that this helps.”

Yeah, the EDIS should work great on your motor. I’m sure that a google search would reveal some Megasquirted VW’s

cheers,

Well, if I remember correctly, that little thing is for dampening the pulses from the fuel pump, but I dont really see how it could do any good on the return side, but then agian, I am no expert on fluid dynamics.

cheers,

Wow very impressive job. I love your attention to detail and tidiness. I’d like to ask you a question if you don’t mind. I’m about half way finished with my Megasquirt EFI conversion on my 77′ 320i and I’m using for the most part the same basic kit as you… 318i manifold etc.c except I already had crank fire with an HPX unit and I went with a Ford Mustang TB. My question is this, what is the round filter looking object that you have mounted in line on the downstream side of your fuel pressure regulator? I keep seeing them in photos of EFI conversions using the 318i manifold and fuel rail. RealOEM shows them in the exploded diagram on early e30 318i’s but lis tthem only as “connector”. Is it some sort of check valve or something. Does the regulator need this part to function properly? Thanks for your time. And once again, beautiful job.

Very nice! And thanks for posting on the FAQ. I have decided to convert my car to the following: Schrick 292, 9.5:1 comp., S-14 crank, essentially a 2.3 Stroker. I am going the same route as you. ‘91 Ford 1.9 EDIS system and Megasquirt using the 318i manifold and 325 throttle body. I am also going to contact 02 again for his exhaust header and new downpipe with sensor.

So are there any changes you would make if you were starting again? From the looks of things I think not. I’m hoping to contact you if I have any trouble. I’m even going to use a similar throttle linkage. I can’t wait to come into the new medium. It is simple, 10 years from now I want to jump in my car, start it, have it idle smooth and run forever. Thanks!

Email me back, that would be great!

Very nice job! Very clean work! Just the kind I like to do myself. If you wouldn’t mind, what was the approximate cost of the ignition setup? I have always wanted a crank fired ignition for my 2002. I have always had trouble with setting up the carbs along with the timing.

TIA,

Paul

I finally got my EFI conversion complete, from fuel to spark. Unfortunately my engine bay isnt as clean as it used to be but oh well. Here’s a link: http://www.designmills.com/category/cars/
