Anyone made use of the Nitrous Control?
Just wondering if anyone has made use of the Nitrous Control features of the megasquirt... seems like it would be real nice since we have control of the fuel and ignition entirely now..

Old thread revived.
I've been seriously thinking about going the nitrous route instead of the turbo route with my current setup. I've become quite familiar with my MS during the year and a half I've been using it and tuning it. I also just finished an install on my friend's turbo'd 6-port vert, as well as started tuning it. It's turning out very good so far.
So, I'm wondering, has anyone ran nitrous on a rotary using the MS? I guess I'm just looking for some opinions or pointers on going this route.
I seriously considered turbocharging my 91, but considering the fact of how much I would be spending for the turbo, manifold, exhaust work, intercooler, piping, bov, fpr, yada, yada, yada; I was thinking I could just go the nitrous route because:
a) I already have a full RB exhaust
b) my current block will only support roughly 350 at the flywheel because I'm unfortunately using a series 4 4-port housing that does NOT have the reinforced dowel landing (my brother's broke at 400 hp at the flywheel)
c) I don't feel like building or driving another turbocharged setup. I want to see what the nitrous setup is like
d) boosted rotaries are trouble for me because I'm always boosting and it's hard to stay under the speed limit
e) I want the option to go faster only at certain times, and can go WOT when ever I want without the boost that goes with it EVERYTIME
f) it'll be cheaper for me, as well as alot more reasons....

Well, James Murray (jsmcortina on msextra.com, the guy who wrote a lot of ms1/extra and worked with me to write ms2/extra) uses nitrous on his car. I believe he wrote that feature specifically so he could use it, so I know it works.
Tuning it is another story. I have no experience tuning with nitrous on any engine, let alone a rotary.

So, I know the nicer nitrous control units you can buy use pwm to progressively control the nitrous solenoid. Is this doable with current hardware in a ZEMs unit, or would I need to add components. What kind of control does MS currently offer? The manual section only briefly sketches over using n2o, but it looks like strictly on/off based on RPM and load.
My ultimate goal is to see how much my stock port S4 NA block can take before grenading. I plan on starting with a wet fogger (up to 75hp) before the throttle plates and moving on to (hopefully 200-250hp) direct port into the UIM. I figure the tranny will go first, but I've got a complete TII drivetrain waiting for that to happen. And when the motor goes, I've got a 3rd gen motor waiting in the garage for me to decide how I want to build it.

You may want pm forum member "JudgeIto" as he specializes in nitrous set-ups on rotary's. I believe he has ran n/a set ups w/ 250-350 shot of nos, but dont quote me on that. The bottom line is as far as I know he's one of the best at these types of set-ups.
