Megasquirt in my 16v

Compliments of JonnyPhenomenon @ vwvortex.com

I recently finished reading through all 16 pages of horror of My Old Rocs megasquirt install thread and I AINT SCARED!

just as the title says, I want to install megasquirt in my 16 valve. I want to get rid of the hideous airbox above all. clean up my engine bay, strip out ten pounds of wires and so on.

(I stole this pic)

edit: before anyone says it, I am still reading the official megasquirt in a 16v faq thread right now. http://forums.vwvortex.com/zerothread?id=1377841

so lets begin:

I wanted to build a kit. (I like soldering) so I went with the DIYAutotune kit and it was awesome. highly recomended.

I would like to get rid of my distributor eventually,(see stage 2) so I will need a special crank trigger wheel and crank position sensor to do that. thankfully a kit for this is available from 034motorsport for about 225, http://www.034motorsport.com/p...d=454 and theres a lesser known setup from a lupo or polo that some people are reporting success with. see that one here:

has anyone else on here done this to a 16v yet that might have compiled a complete parts list for the project?

the end result will be cleaning up this:

so that the whole car will look like this:

and I wont be ashamed to open my hood at the next car show.

EDIT: I am moving my parts list to the original post and I will edit it as things change.

I should mention that I have a carputer built into my center console already, so the megasquirt ecu will be permanently connected to that.

EDIT: actually no. I have since removed my carputer. 

some questions:

If I remember right, the old megasquirt required a different board if you wanted to drive the spark too instead of using a dizzy. is that still true? or will the MSII handle that now?

can a MAP sensor work as a replacement for a throttle body with TPS?

do I need an additional coolant temp sensor or will the stock one suffice?

what kind of injectors do I need to fit into the 16v head? the stock injectors are long and narrow, not like any other injectors I have seen.

thanks for the help 

so, a trigger wheel on the crank pull then. too bad something couldnt be fabbed up under the valve cover.  

this 034 motorsport has a few thigns I was looking for. nice link.

does anyone know the difference between the megastim 2.2 and jimstim 1.3?

Note:

one reason I am building this megasquirt system, is so I can eventually track down a 1.8t and do a motor swap without worrying about needing the entire ECU and wiring harness out of the donor car. this makes it a LOT easier to order one though a junk yard.
