i'll be using a D-jet wiring harness. i know a few of you have done this, i'm wondering how you went about it and what you used.

so far is have the '75 dizzy and ignition box (which i hear can be used for ....triggering or something?), the saab ignition module and pigtail (will i need this?), and a green manual for a D-jet car that tells me resistance figures for the various sensors and such. also i have a set of modular V8 ford injectors to tune with (pre-turbo).

i've read some stuff, but i'm still defintely a MS noob and any helpful advice would be greatly appreciated.

Sorry.. but it sounds like you have a bit more reading up to do..

I'm not sure about specific B20 things, but you can use the Saab ignition module for triggering, either that or you can wire in a VB921 and use that. how are you getting the injectors into the manifold physically?

edit: are you running v2.2 cause you can get one from someone? or just because?

Injectors in the head perhaps?

this.

yeah i have a ****load of reading to do, i don't know much of anything about it.

why am i getting 2.2? because an assembled box + daughterboard kit cost me just over $100 from a friend.

Sweet, I asked cause I want to do this soon.

this.

Yeah I figured, awesome, cheap is the way to go! Good luck and get on that reading!

Here's a link to somebody who MS's a B20:

You can use the '75 ignition as a stand alone setup (you won't need the Saab module), and have MS run the fuel side only.

I run a B21 engine in my 122 with MS (V2.2) running both the fuel and ignition, but when MS was first installed, MS only ran the fuel side, and I used a '79 242 ignition setup (similar to the '75 setup) for spark.

I'm currently running:

-'65 Volvo 122 with a B21F/M41
-LC-1 WBO2
-MSI V2.2 running MSnS-extra (29v) (running electric fan control)- tuning with MT2.25
-Bosch 004 Dizzy/Bosch 139 mod
-Bosch 21lbs EFI injectors
-Volvo 850 Bosch TPS
-Closed idle control with Bosch 516 motor

whats this about a dizzy mod? and what cam are you running, malloy?

Yeah I would run the 75 ignition and just replace the K-jet junk on the B20. You can take an RPM signal right off the (-) coil. You will need most of the d-jet fuellie parts, injectors, rail and such. I used the stock d-jet injectors, static FPR and rail, fuel pump, CLT, IAT, Warm up regulator, added a wideband O2 sensor, 850 TPS. That should be enough to get you set up on fuel tho. You will need to add either a flyback board or injector resistors.

If you are using a d-jet harness I have an excel spread sheet that I used to get everything hooked up and running on my 142. Ask all the questions you have, we'll try to help you with everything you have questions on.

i have the djet harness and the djet fpr, but i don't have the injectors or the rail. is the injector spacing different than the OHC redblocks? i keep forgetting to take my tape measure to the junkyard.

i'll use 740 turbo fuel pumps, 850 tps, and i have good 19lb/hr injectors (not the pintle-type) to get it running on, i know i'll need bigger when i get a turbo going. i may just use greentops from the get-go if i remember to grab a set from the junkyard. wideband is also on the list.

i'm afraid i don't know what the djet CLT, IAT, or warm-up regulator is. i do know that i don't have any of those things and that i apparently need something to serve those purposes :lol:

Well he is running a B21 so hes in a completely different ball park.

I have a feeling you can use MS to control spark using the spark box you have, while making some modification to the dizzy itself. If it is similar to mine there was a mechanical advance mechanism in the dizzy that advanced the spark w/ increasing revs. I removed the weights and locked the dizzy down so that MS controls the spark angle now. I think you might be able to use the pickup is the dizzy to send a signal to MS and use the box as an ignition amplifier to run the coil but I don't know enough of how that all works. Let us know what you have and what you plan to use.

CLT-Coolant Temp sensor
IAT- Intake Air Temp sensor

I have spare d-jet injectors, rail, FPR, and sensors I believe. PM your email and I'll send the excel sheet on using the stock d-jet wiring harness to db37 connection. Of course minor changes are needed since its a slighty different set up.

ooh i do have the IAT actually. i will need the CLT however, do i really want to run the djet injectors? i don't care much for the way they seal to the head/fuel rail...

What's wrong with how they mount/seal? It's not like your running any boost to blow them out and I doubt you could anyways. Good luck finding an alternative...;-)

I ran D-Jet injectors in my B20E MS powered 122. No issues whatsoever. In fact, I got 30+ mpg with them.

Do you have an EFI head? I presume so. If you do, you should have a coolant temp sensor at the front of the head. All you need to do is get some readings from it (pot of water, thermometer and ohmmeter) and MS will figure it out.

well i don't like the lock ring that clamps em down. more importantly i don't have any, and i wouldn't have the first clue where to get them. or the part they screw onto. and by "seal" i actually was refering to the fuel seal- as in using a bit of hose on a barb.

also i don't have any Djet injectors :grrr:

i do, however, have a Kjet head.

Well...I might just have one of everything you need. I know I have a set of injectors and I think I have the hold-downs as well...

update- harness is sitting next to me here. as is the ms box. spe1983 sent me a file with a spreadsheet showing which pins to solder to which wires on the d-jet harness. however i didn't have excel (but now i have vista 64 ultimate, so it may have something to at least load excel files)... however now i can't get ahold of him to resend the file.

anybody else have a recipe?
