got a little close this weekend with help from my brother (who has ms'd about 5 vehicles or so)
surprisingly all the sensors that came with my kz1100b2 worked perfectly, the only one I had to modify was the TPS (had to reverse 2 wires to get it to read right) stock temp sensors were very close to how bosch sensors read. the stock fuel pump relay was wired weird, computer sent + vs - that the ms sends, so I added a relay that the ms computer turns on to send + to the stock relay.
the only wires I had to add were 2 sets of injector wires for each bank. I have to finish modifying my fuel pressure regulator, and should have it up and running very soon. then I can tank it to work and get it on the dyno and see how it's doing.

One problem with the new microsquirt is it can only handle 2 low
Impedance injectors. I have 4

Boostable, mistake on my part I guess. I thought the low impedance injectors would be better, I heard they are more responsive at lower rpm. I just realized mustang injectors are high impedance so I'll just use a set of those and everything will be fine. I think that stock GPZ1100 injectors are low so that is something for everyone to be aware of who might use stock hardware. I also came across the fact that the asian tuners are using resistors and a calculation to adjust for this. Im just going with a set of high imp 30lb injectors to keep it simple.

ratvespa, do you have a build or project link? Id like to see all of the details of your setup, are you going fuel only or fuel and ignition? What computer, software, how do you have it all hooked up?
What injectors, fuel pressure and pump?

Innovative LC-1 wideband O2 systems are selling on eBay for $133 complete with O2 sensor right now. That's about $70 cheaper than the usual price.
I just bought one and figured someone here might be interested.

OK guys straighten me out here! Instead of using a toothed wheel, why would we not use an electronic crank trigger like the Pro Trigger from Dyna?

What am I missing?

bootstable,
for now I am just going fuel only, MS 2.2 thats been flashed so it has the extras (mostly just wanted the larger fuel tables.

pretty much everything in the bike is stock GPz (kz1100b2) efi, except for the injectors, they were from a mid 2000's gsxr600, I had to make some parts to make them work in my stock TB's. fuel pump is stock, fuel pressure regulator is an aeromotive one (check my post, I think I posted a pic of it in this thread)

I don't have a build of it, just kind of doing it as I find time.

the wiring is pretty much all stock, MS is going to sit where the stock computer sat. the only wires I had to add were injector wires, since the stock harness had the injectors hot all the time, and they all fired at the some time. I went with 2 banks with the MS. if anyone is doing 100b2 I can scan my ghetto wiring diagram I scribbled on some paper.

as for the trigger I am just using the tach output on the dyna2000. it should be a clean enough tach output for the MS. if I was controlling spark I would need a toothed wheel.

Boostable, Im going to try using the stock pickups with 3 diodes to combine the signal into one.

Ratvespa, more details on your injector setup please.
