the map looks nice (100% boost comp) i think your idle % map needs to be finished, and your idle fuel and ign. FB needs to be toned down. and you dont like much timing above 15 psi do ya :jester: (I assume its a pretty big turbo)mods that make a difference: 8.5:1 compression, bc stage 3 cams, CNC port head, 50 trim, 900CC injectors. AEM 3.5bar, GM IAT sensor, return line on boost/vac source base pressure 43PSI.
nice mod list:thumbsup:
O2 feedback sucks ass. It takes forever to get to its target. No matter what gets changed (its 100000000000 times better than the wizard right now...but no where near perfect)
yea you took out most of the gain on the o2 fb
Hot start problem that i've complained about since i've owned the EMS....let it sit for 10-20 min after driving around and then restart it, it runs lean (18-19:1 afr's for 10sec-2min) then settles itself out.
may be your o2 FB is delayed big time in the cold and you need enrichment we need a cold start logw/ the start screen parameters
Warm-up enrichment afr's are different EVERY TIME. This confuses me. It could be the same temp outside, same IAT's, same everything and it'll be at 12:1 once and 14:1 the next.
its based on the coolant temp
Slowing to a stop, as soon as you're out of decel fuel cut, it runs 12:1 until you reach a complete stop....then it idles normal again. (even though it sits in the same cells as the idle)
i would need to know what your lowest load is in psig and may again be tied to the o2 FB
might think of more later.
Download the latest version of AEMPro here. Also includes AEMLog!how can i open these files? everytime i try i get some scription code...sorry comp newb
if I was you I would set up that sensor and use the sensor gain to match it up. once its set up correctly I think you will be plesently suprised :thumbsup:The reason there is no o2 sensor configured is because i changed all the settings. I'm running an Innovate wideband and the numbers are way way out when you compare the actual AFR to what the AEM sees. After dealing with AEM a bunch on this I was able to go in with the laptop and change the settings of both the LC-1 and the AEM so now they read the same. Because I changed the afr/volt table it unchecks the O2 sensor I have.
The base settings are way of. It ossilates way to much before it reaches the target O2. I've been playing with it but i really dont know what im doing when it comes to that.
Im still working on the boost fuel table so I turned O2 feedback off under boost.
I dont know whats going on with the idle very much. Tried a million things but still working on it. I only recently figured out how to get it to run off the maps. (TPS voltage thing)
I recently got rid of my AVC-r and am now using the EMS to control boost, so i'm tuning as I go. I havnt gone over 16PSI with the new tune (ran 24 before, but not full boost comp) So still working on the fuel/timing for anything over that.
your raw was almost toped out it max's at 255 you were at 233 :wah?!: that leaves less than .26ms of pw adjustment up top (you had NO head room at all)Why would you change the ms to 25? I had it at 30 for a while but let AEM pro rescale it and thats what they put it too.
