What injectors are you running and how lean can you idle them? I'm tired of not being able to idle my 550s that flowed closer to 600cc at 44 psi. Which means they flow even more than that at our static 65 psi of fuel pressure. The MS1 lacks enough resolution to idle them any leaner than 13:1 on a good day with hi-res.

Hehe, I was idling my 550's at 4 squirts and idling 19:1 missfiring when playing with injector settings. Low ohm FTW. Also four sprays instead of two makes for a snappier and just different idle. It falls to an idle like a diesel does. Hard, fast, and just lands flat fast and hard and sits there rock solid. It's neat.

I have stock injectors now and 550's at Deatschwerks getting serviced. Supposedly, this ECU will idle large injectors easily. It says how and why in the manual, but I don't recall how it does it. Once I get this map done on stock injectors I will be saving it for future users and then should be able to do a percentage scale to convert to the 550's. I will then autotune and save the map for 8 PSI. After that I plan on getting an EBC, upping to 10 PSI. I will autotune and then dyno tune.
Anyone that is interested should download the installation manual and the software. Both function without the unit. They will answer a lot of your questions.

I just wanted to make something that was clean, had good flow, balanced runners and fit the SR20 T25 easily. This was a modification of the simple "log" manifold that drove the gasses smoothly without running into each other. The only other option was a top or bottom mount and I didn't think that I would gain anything significant for a much larger effort to build.
