Wouldn't the rapid learn mode eventually tune out the lean tip in?

Attachment 207776

Lean tip in is not part of the fuel map and thats what the rapid learn mode tunes isn't it? Acceleration enrichments usually have to be hand tuned like every other EMS.

cant wait to have the 2nd adaptronic nb in the states:mad: going to start fixing my 2 leaks and figuring out the shitty idle asap

Word. I have messed with this a lot, including timing adjustments. I finally just gave up and I idle them rich, like 12-12.5:1.

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 hate you.

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.

Good to see that you are reading up. There are some things that are different since this thread. It will be pretty self explainatory when you see the new pics that I took before taking it apart.

Stein just out of curiosity, why didnt you go with a more exotic manifold?

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.

thanks for the explanation sir :) have a nice night :)

Thank you. I am able to handle this mod, but it will be nice to have additional help.

Have a great day,
