should I just throw away a free EMU?
I got my 96 about a month ago. The car came with a mostly complete turbo kit:
BEGI cast mani and DP
2.5 exhaust with bung for WB02
rx7 injectors (460cc? I forget)
My goal is a fun 220 rwhp summer car which will see an occ auto-x and hopefully will be reliable enough for a lapping day.
My friend is rebuilding his bnr32. He has offered me his never used EMU with MAP sensor for free if I will use it (ie: I can't sell it and use the money to fund a MSpnp.)
For the most part I hear that the EMU is not worth the trouble, and that I should just go straight to the MSpnp for about $600.
However, I do see that people have had success using the EMU on FI applications.
So, am I correct in saying that I can use the EMU, but I will need a wiring harness (unless I am willing to splice into the factory harness). I think I need to clamp the O2 signal when the ECU is in closed loop. Some have indicated that this is not needed. What is the final word on this?
If I do need to clamp the O2 signal, do I have to make/buy a circuit, or is there an existing feature on the emu that will clamp the signal? Where can I find more info on how to do this?
I know many will say, forget the EMU and just get an MS, but it is not entirely clear why the EMU will not work. I guess I am wondering who has a reliable EMU set up running for several years?
