Re: The beginnings of a Megasquirt how-to guide
The DIY Break out board is the best way for an SVX, but since you've already been through the wiring once, you might be better off just splicing it into the harness. I'm not sure without seeing your setup.

Re: The beginnings of a Megasquirt how-to guide
As I'll be rebuilding my spare engine here soon, I wont have a spare vehicle to 'test' my setup on so it has to be removable. So I'd rather be able to plug/unplug the ecu quickly once I'm done testing a tune. Which is kinda why I'm leaning towards a piggyback, cheaper and I can set the modification tables to 0

Re: The beginnings of a Megasquirt how-to guide
Ah I see, so the breakout board makes it truly pnp?

Re: The beginnings of a Megasquirt how-to guide
Very nearly, there are a couple things that will need separate wiring added, like the IAT sensor, wideband O2s, etc. But everything the stock ECU connects to would be pnp.

Waiting till I get the rest of my parts car money and I'll be ordering a MS2 with a break-out board!

Re: The beginnings of a Megasquirt how-to guide
MS2 or MS3?

ms2 with the adapter board. most likely anyway.

Re: The beginnings of a Megasquirt how-to guide
Quick question, I've found a couple other people doing EG33+Megasquirt, did you attempt to just use resistors at all to clean up the signal, before you used the VR board?

As for updates, I don't have anything for you right now. The projects have progressed in a weird way so I'm kind of stuck without being able to work on the ECU stuff right now. However, I have already pretty much already documented everything needed for someone to get started with their own. Are there any more specific questions, like what BackWoodsBob has been asking?

Re: The beginnings of a Megasquirt how-to guide
About an hour and a half ago.
And thanks for your help, I'm sure I'll have more questions! Though mine is but a lowly MS2 and not the 3/3x. I imagine the VR2 board probably has some op amps and so on to first receive the lower-level "dirty" signal, filter it through an amp, and then output a nice clean waveform. I have a few days of playing around with the megastim and getting used to the software before I actually head to the car. And I'm probably going to either cannabalize the spare ECU that I have, or buy a breakout board for swappability (Either option requires a bit of time though). I also need to get an IAT sensor still. ...and then, upgrades (bigger injectors, and, well, M90)... Thanks! Last edited by BRZCory; 08-09-2013 at 04:53 PM. |
