Take a look at this, I want to order this but I don't know if it will work with a rotary.

I need to build a megasquirt for my TII swap and this daughterboard looks like it's full of features.

 

What daughtercard?

 

Still waiting...

ha oops, It was late.

 

I used to live in DFW how do you like it there?

 

That board's VR sensor conditioner probably will need a modification to work on the rotary engine without noise issues but other than that it should be alright.

I have one. I did have a lot of noise problem now then ken mentioned it. I always thought it was something else causing it. What mod do you think need to be done.

 

What problems did it cause

 

You need to ground pin 14 on the lm1815 for the 2nd trigger VR conditioner, and potentially put a 0.01 uF cap across G+ and G-

I had real bad cranking problems and random spikes when driving. I tried every grounding trick in the book. I eventually gave up and went with a modified cas. I just dug out the board again gonna upgrade to ms2 so i will give it another go. Thank for the tips.

 

does the DIY daughterboard work pretty good

 

Which one are you talking about? Link?

Ken

 

DIY has the Zeal daughterboard, I'm hoping to not have the noise issue with this one.

Anyone have a ms-II for sale?

 

I designed that one and use it in all my setups. It does not have noise issues for me as long as it's set up with pin 14 on the 2nd trigger lm1815 grounded, and the main grounds for the engine, battery, and MS are done correctly (same as stock) and clean.

I normally use a v3 mainboard as well, so I only use the second trigger conditioner that's on the daughtercard, and the main trigger is conditioned by the v3's built-in conditioner.

Do you have a write up on that setup
