OK, so I have read the FAQ, the MS manuals and other MS related web pages. Chuck (Rx7 nut13B) is helping me out with this project and we're both learning.
So I bought this Ebay link off of Ebay, its a pre assembald and tested V3. OK so the questions are, do I need to modify the CAS? or was the only with the 2.2 - the erorrs board? And ther are 2 FI outputs, it seems as though (from reading) that on is for the secondaries and one is for the primaries, but I did'nt think they fired at the same time on the stock ecu, or do they? And this is the project that the ecu is going into, just FYI https://www.rx7club.com/2nd-generation-specific-1986-1992-17/frankenstein-motor-pics-inside-610501/

Does anyone have a really spacific diagram of the V3 thats set up for the FC, possibly with pics?

Thanks

 

You don't need to mod the CAS... unless you don't want to build an lm1815 circuit. It's up to you and has nothing to do with 2.2 vs v3 board.

Yes, you would use injector channel 1 for primaries, and channel 2 for secondaries.

They don't fire at the same time on the stock ECU, but it doesn't seem to cause any problems anyway. .

I don't think there are any specific diagrams... just the FAQ which tells you which mods to make and how to make them.
