 I recently completed a Megasquirt fuel + spark conversion on my [[Jetronic]] [[M20]]B23. I first [[Converting_to_Motronic_1.3|converted it to motronic]] and then set it up for wasted spark. This guide will be a general guide, but I will also add specifics for series 1 E30 owners and L-Jetronic E30 owners. While I will list possible options this guide will be tailored for [[Motronic]] 1.3 single coil and wasted spark setups.

-I highly recommend purchasing TunerStudio. While it is $50 and most e30 owners are broke tight arses (i am guilty of this), spending $50 to be able to quickly dial in your ecu is well worth it. The VE Analyze Live feature has been quite helpful for me as i am not too technically minded. While the free version works perfectly for all intensive purposes, the VE Analyze Live and ignition diagnostic features are fantastic.

 === ECU Firmware ===
 This guide will assume you are using MS2E 3.1 (Latest release, if it isnt posted on the ms2e website yet go to the support forums to find a download link). 3.1 is now tried and tested and has many benefits over the old 2.1 release.

 === Wasted Spark ===
-With Wasted spark you will be using non factory coils. There are two types of coils, ones with logic boards allready inside them and ones that require ignitors. The coilpack i decided to use was a GM V6 coilpack which are quite cheap and readily available at australian yards.

-For wasted spark all that is needed is the extra coil drivers and wiring to them. while it is possible to just use the default sparkA output and the 2 spare outputs of the glensgarage idle board, I ended up using a seperate coil driver board. This was because the ECU i got from DIYautotune by default does not have a transistor installed for the sparkA output.

 The wiring is dependant on the MS ecu you are using. A great guide is provided by DIYautotune here [http://www.diyautotune.com/tech_articles/using_bosch_bip373s_with_megasquirt.htm].

 I wont go into too much detail here as it has been covered many times by many people. It can be installed into the case or outside the case, i prefer to just create a harness adapter and have the ecu seperate as i am not too good with fiddly stuff. If doing wasted spark do not use the SPARKA output of the megasquirt ecu.

 A stock logic output from the MS ecu worked perfectly for me (no transistor/relay involved) i used the JS10 output (the spark output of db37 connector).
 === Settings ===
 This is best done by looking at the website [www.megamanual.com] and other popular tunes. It is quite simple, just make sure when doing wasted spark you have the right outputs selected. For the trigger wheel the settings are 60 teeth 2 missing and use 84 degrees as your tooth #1 angle. The other critical thing is to make sure you have the injectors set for high or low impedance. And after long cranking with no fire up make sure you just crank it for a while with flood clear or with the fuel pump relay removed, otherwise you may damage something.

 The LC1 can be wired into the stock harness. I did not take pictures but i just cut the connector off a bosch narrowband and used that. The example i had had four wires, 2 whites a grey and a black.
-The wiring i was told was Grey = Earth, Black = signal, White = Power. I cannot confirm this yet as the ecu has not been run with this lc1 setup yet.
