Megasquirt Update, with PICS Options

[yarin]

I Was about to dig up my old thread from two months ago... but I felt some of these pics deserve there own thread.

I'm really moving along on my upgrade from carbs to MS. I should be able to power up the system this weekend and crank it the following weekend.

I chose a rather different approach to my install, a combination of logic, simplicity and durability. Please give me your input. For those who aren't familiar with MS go to www.megasquirt.info and www.msefi.com (forums).

I bought all of my Megasquirt parts from DIYautotune.com. Excellent vendor, i suggest doing business with them for anything.

What's left:

finish db-37 connector
connect all wires in relay box
mount intake plenum, connect DIY PVC intake
install gas tank
checked double check and triple check all fuel connections and wiring
configure MS
crank!!

Here are pics:

QUOTE (lapuwali @ Mar 30 2006, 10:55 AM) Switching to MS2 from a fully working MS1 setup involves just swapping the processors, flipping a switch in Megatune, then using the new options you get from MS2.  The maps you make for MS1 should work.  So, learning how to do all of the tuning with MS1 is hardly wasted effort.  The MS1 software is still more stable than the MS2 software, and it's still likely to be awhile before the MS2 code has all of the options and stability of the MS1 code. Almost true.... If you were running MS-n-S EXTRA on your MS-1 processor and you upgrade to MSII - you might have to reroute some of the extra inputs that you might have been using... for example - I used to use the LED17 output for my EDIS output - and MSII has an explicit output for that - so I had to reroute my Xxx (whatever it was output). This basically means you can't swap back and forth a lot; but it did take less than 2 hours for me to make all the changes and migrate everything over. The spark and fuel maps can be moved over, and if you have an 8x8 map in your MS1 - the software will interpolate it up to a 12x12 map for the MSII, so that's a very painless process.

If you're starting with the v3.0 board, though, you should be able to use one of the other new v3.0 outputs for EDIS with MS1, rather than steal one of the LED drivers. I expect MS2 will, eventually, be able to drive the LED outputs for yet more "extra" outputs, too. I'm assuming it can't do it now, but only for software reasons.

The main thing you'll gain with MS2 over MS1 is the CAN support, which will be required for some of the later things coming, like the router board. This will be required if you intend to later move to something like coil-on-plug ignition, or you add so much power you need traction control, or you add a turbo and need to idle well with big injectors (hard to do right now) and don't want to go to the expense of staged injection (can be done now even with MS1).

In any case, by the time you have your MS1 working and tuned, this may all be worked out, and you can switch to MS2 easily if you decide there are features you have to have. MS1 will still be adequate for a long time, though.
