ok i have a few questions. i am going to get the ms 3 and the data cable to hook it up to the computer. what else do you think i need. i dont think that i am going to hook it up into the ing i am just going to hook it up to the fuel. what do i need for the ms and what do i need to keep the stock ign. i think that it need tps. has anyone hooked it up to the ing. i have read that people have it hooked the the leading only right or what. Please i want to start this project. any help would be great.

well are you going to build it from scratch? if you are, then you will need allot more things. seccond, ditch the stock ecu and ithr go with distributor, or if you wanna get more complicated go with the ms ignition for rotaries. or, you ca dissable the stock ecu's fuel controle and it will adjust timing accordingly, but up untill redline and the stock ecu wont read boost or anything. so unless your going na with a stock port or anything then you wont be happy.

 

i think that i am going to run the v 3.0 and run full ignition the the ms. Because they said that you can do it with the 3.0 and you just have to replace a chip or something

 

you where wrongly miss informed. you build up a seperate board for it to interface with the ms.

i suggest you do allot more reading. ALLOT more.

 

Actually with a V3 board, you don't need a separate board for the vr sensor conditioner. It has a built in one, and you can use an lm1815 chip and some other components in the proto-area for the second conditioner.

 

Or grind a couple of teeth off the CAS - now idling! Rain tonight, otherwise would go for drive. 12-1 works.

awesome! is that with or without trailing?

 

That's WITH trailing. It had a problem over 3K or so with dropping ign events but scope says that the v3 pulse conditioner/zero crossing detection circuit starts missing some of the VR pulses when they're coming fast. I'm sure it's a matter of playing with the gain/hysteresis pots on the v3 board as I can change the response by fooling with those. I need to get it back on the bench and document the response of that circuit in respect to those pots so I have a handle on what does what. I'm not a huge fan of twiddling pots until it runs clean and not know why or what was incorrect. Your code seems to be just fine at first look. I'll be on the bench this afternoon and may call you if something seems ambiguous.

well damn. i dumb. but what is stopping me is the lack of retarted simplicity like the distributor and coils provide.
