1994 RX-7: Xcessive LIM & Fuel Rail install (in progress)

[TitaniumTT]

Scotty, I'm quite impressed with your build, I must say. You did a fine job with the fuel system. I was hoping to be the first one here to comment on the ID injectors. Which are you using? the ID 750, or the 1000 or a combination. I believe I'll be stuck with 4 1000's or two 750's and 2 2000's. We'll see, I still need to call Paul. Loving the FPR setup though. Very awesome.

Rotaries love the fat dumb and happy idle. It keeps the flame front slow and steady. My car loves the .85-.87 range for idle as do just about all the other rotaries that I have seen. IGN timing is around 5* @ idle. Holds really nicely for me.

Fuel pressure. I would run it as low as possible. It's my opinion that 50psi is just too high (unless Paul disagrees) however, I know a gent at MoTeC that is running his S5 @ 39psi static with 4 ID1000's. He sees 82% duty @ 15psi with .8L at redline.

Lambda's - there is alot more power, response and believe it or not, boost stability to be picked up by leaning at the fuel map. What I found with excessivly rich AFR's is the unburnt fuel increases EGT's as it burns in the manifold. This extra energy spools the turbo's harder for that split second. It's exponentially worse on a misfire.... tons of raw fuel expanding in the mani makes for unhappy turbo's, stockers anyway.

If you would like, I'd be more than happy to send you my timing map to compare with yours.

Why did you choose the AEM over the PFC. For your setup it would seem that the PFC would be the way to go (I honestly don't know anything about the AEM) or did you just want to experiment?
