Mine was as well then I bumped the idle up. Try adding 50-100 RPM to idle.

 

Alright I'll try doing that, it's idling at around 800rpms right now.

 

Hmm, idle didn't seem to do much. Still idles at ~9.5afr when fully warmed up, :(. And all the time when not in boost at runs very rich as well around 10-11afr. I'll see if I can fix this, any suggestions?

 

post some logs with file

 

Yes please post your EM2 and log files.. I’m idling between 13.2 and 15 which is pretty much stock.. I'd like to see what you are doing differently out of boost..

 

I'll post my map when I get home a little bit later, but it looks very similar to yours, I don't know what's going on. Could it be a bad injector maybe? I also have FM dual feed fuel rail but that shouldn't matter much at idle.

 

Here's my map, what do you think?

 

i would not mess with the idle adjustment settings for now. let your stock ecu try to idle. also in the af target tab under properties feedback cycle might be changed from 20 to something like 100 or 200 ms. only turn on the maps that are critical for now. maybe ignition, af target, injection, to get it running first than later mess with the other stuff. for simplicity purposes just start off with least active settings. ps, where did you ground your lc1 i am having ground offset problems it keeps recallibrating. by itself.

 

Try this one.. I only changed the Injector sizes..

 

My LC1 is grounded to the steering column under the dash, never had any problems with it recalibrating.

Thanks mx5-4me I'll try that, hopefully I can figure this out.

 

My car idling using the RusMan.zip map ..

 

did you ground all 3 wires at the same place? i did one at the engine bay area and it is giving me problems also where is your power coming from? thanks
maybe we can kill 2 birds with one stone here lol

 

If I remember correctly I've grounded all my wires to same location.

Damn dude, that idles is just perfect! Mine's not like that though, still around 10afr, I'll check all the connections in the engine bay, might be a vacuum hose or something like that, cause I have no idea what's going on with this. Thanks for your help though, I really appreciate it!

 

rus did you get your car to run? clear out the water adjustment map and try it than put everything at 0
i played with mine today and the car runs 10's like **** once i put in 0 everywhere it was fine good luck

 

I'll try that, thanks for a suggestion. It runs good, idles decent, just very rich. I'll see what the water adjustment will do.

 

Sorry to bump an old thread, but I now have the RX7 550cc and EMU.

I am using the rusman.zip map, with the idle control and water adj zeroed out, and I am still having the hot start issues.

Anything new come out of this?

 

No, I ended up buying smaller injectors, runs better now.

 

Just curious, I had some RX7 550s flow tested at injector rehab and they rated them at 550 at 2.25 bar -- is 2.25 bar the standard 43.5, or am I wrong in thinking it converts to something else?

Also listed at http://www.injector-rehab.com/kbse/flowrates.htm

I'm trying to nail down 550s and EMU on a 2001 before I go turbo, and I am having the ~5000 rpm rich stumble and idle problems.

 

Just buy a MS.

Thats what I did.

 

Did anyone solve the hot start issue with the 500cc? I just got some and am playig with the lag times I am having the hot start issue now. If anyone cares I posted the log and file to look at.
