eCtune

Made a few fueling changes, tell me if it changes anything.

Use 3rd for all. Also, if you can't get rpms below say 1500 stabilized to take a good reading, you can at least be fairly confident that rpm's that are less than where you can get it stabilized would want a little less fuel.

Closed loop needs disabled. Fuel Cut needs to be enabled. You had it disabled in the vacuum leak disable check box. Other than that, you need to do your best to tune the fueling in your low/medium load cruising areas. If the fueling isn't spot on, it's going to cause issues other places in the map. ...

^ I have to agree with Bugermass. Running in closed loop is just gonna make the problem impossible to find. It's making corrections to fix what's wrong with your fueling, which is where your problem most likely is. How are you ever gonna find what's causing this when you have a correction trying to ...

Post a new .cal and log when you get a chance. Make sure it has a few good decel runs in it.

You need to do this: Post #2.Setup Fuel Cut settings I found it like this in the search: fuel AND cut AND settings

Fuel cut is just that.. fuel \"cut\". For it to go 100% lean is completely normal. I wouldn't worry a whole lot about it until you get the rest of the map pretty close, but 14.5 should be fine if you can get it.. I've noticed that I can lower my first column down to almost nothing at all, and it wil...

If you are making changes to the fuel map based on data that was taken when you are on and off the throttle, you will never get the AFR's tuned correctly. The only way to get accurate data is by going the same rpm and same throttle long enough for everything to stabilize in those cells. When they ha...

Definitely not supposed to be all crazy like that. Try looking at some of the .cals in the \"User Posted Calibrations\" section that might be somewhat close to your application. About the fuel by gear, not saying it's incorrect, but I haven't had a use for it. If the AFR's are tuned properly, you wo...

convinced him to change his setup to run E85 once he got home and his problem was solved lol .. So if you have E85 or simular near by, this would be a good soultion to whats gonna be a problem for you.. If not, then I'd change the setup. Yea, the E85 is working out great. The biggest downsides to r...

Maybe that's what it's doing.. I would try a different distributor. It may be a shot in the dark, but it seems that everything is for you at this point. :D I had a distributor go bad on me a week or so ago on a dyno. It would run fine in the low rpm's, but as soon as it hit 5200 it would start cutti...

Fixed! Thanks Calvin, and Merry Christmas!

x2 First thing it said was \"unable to load rom\", then I got the message above. Tried to re-install, same thing happens.

Bringing this thread back from the dead.. A type K thermocouple, and the 5V K-type adapter are all that's needed to monitor and log EGT's in ectune data logging correct?

I've had it running with close to this setup for over 10k miles (the major change is the header), and haven't run out of injectors yet. I am thinking about changing them out for the RDX 410cc's or possibly the injector dynamics 725cc's to see if I can get some more consistent AFR's though. Any other...
