Help with wiring a haltech e6k m42 turbo

[benjamin]

Hi guys im currently stuck with my e30 m42 wiring.

Im doing a plug and pin with a haltech e6k and just need some help with the wiring . Im just doing this on a budget and want to make it work with this computer if I can as I already have it.

so what I have done so far>

idle control > pin 4 haltech
TPS           > pin 31
TPS/MAP 5v > pin 18
coolant      > pin 30
road speed input > pin 5
Air temp    > pin 29
fuel pump relay  > pin 33
12v ignition switch > pin 25
Air con      > pin 28
tacho        > pin 27

So at the moment im stuck with the coils and injectors.
The standard setup is 1-4 and 2-3 injectors together and I want too use the standard setup for simplicity.
Im assuming with the injectors I can wire to any output and just leave two outputs not used? Then just run in multipoint mode ?

Coils> I know they are dumb igniters but not sure how to wire to the haltech.

here is a link to the manual in PDF

And a few pictures of where im at >

I am currently doing similar with an E11 on an E36 318is. I have not measured the injector resistance (I am using other injectors) but so long as they are high impedance you should be able to drive more than one from a single output.

Ignition wise , how are the coils driven in an E30? (The E36 is the first BMW we have played with) The E36 has the drivers in the DME so we are using a four channel ignitor sourced from Haltech to bypass that problem.

Hey, I'm using bosch 42lb injectors I'm pretty sure they are high impedance.

For the ignition the standard computer has the drivers built in so I'll guess I'll need the four channel .

Thanks I'll update as I go

I took a different tack in the car I am doing. I removed the Haltech from another car (That is getting a younger ECU) so I cut the wiring look back to terminate all the engine harness stuff un the wiring duct that is above the back of the engine in the E36. They are terminated in a series of DT and DTM connectors and then I have recycled the original wiring to the engine or replaced it as required. For one thing I spliced into the existing injector wiring to change the car over to sequential injection.

We plan to do an engine transplant later so all I will need to do wiring wise is unplug the engine side of the connectors, and then run new cabling as appropriate to the new engine (Probably a Nissan SR20) and terminate them in new engine side connector shells and plug it back in again.

By the way. Seeing you are in NSW. When I last bought ignition modules (Did not even check this time) I could not buy a Huco triple channel (I have two on my other car) by itself for the Haltech price that gets you the igniter, heatsink, plugs and pins. If you peel the Haltech sticker off it was a Huco underneath. And that is with me getting trade price at my local Autopro.

You mean 4 channel ? I have a 3 channel haltech one here maybe I can sell it.

This microtech one looks cheaper but very bulky :

No, three channel, my other car is a six cylinder with two igniters.

A word of warning that you are likely to run into the same problem I just did. It appears that the BMW OEM coils require a higher drive current than the Haltech/Huco drivers limit to. New coils are probably on the agenda to match the non OEM driver.

Assuming your ecu is not the constraint, I have had success with Bosch igniters in my project. If budget constrained you can build you own using BIP373 chips.

As far as I am aware, the Huco is a direct replacement for the Bosch nut i my case I get no or very weak and inconsistent spark with the factory BMW coils. If I put my timing light inductive clamp over the coil primary wires between the driver and the coils I get consistent flashign in time with the compression strokes as expected, but if I then to to the plug leads (Which I metered out to make sure they have not broken down) nothing.

I test wired an old Bosch HEC716 I had from another project onto one of the coil connectors and that produced spark. I am just in a bit of a bind at the moment, the cost is relatively close between fitting 4 X Bosch HEC715 coils (The 716 is not available in that style any more and the 715 would use the same plug leads as the factory coils) or 4 X LS1 Chev V8 coils which include inbuilt igniters.
