Hey guys I've recently switched from a greddy emanage over to an adaptronic and I'm having a few issues. I've got my cruising/load fuel map set up pretty good and not having issues there. But depending how I tweak the fuel down low at idle I either have a really rich idle or the car will lean out/stall very quick when trying to move from a stop in 1st gear. Few other things, my tps signal is wonky like not reading steadily or accurately at all when idling, And every now and then when idling it'll drop to like 200 rpm and come back up, like something cuts out or something, thats not that big of an issue bc it doesn't die.
It's and 89 S5 Jspec.. if anyone could help me figure out some fine tuning with this thing that would be awesome. In addition to the leaning/stalling from neutral to 1st gear starting to move it also dips rich 14.8-15.8~~ in between shifts. If the stop to start stalling is bad sometimes neutral to 1st, 1st to second I will see afrs as high as 16.8-17.8 just for a moment before it comes back to life. Not really worried about my engine here but it's really annoying and makes it far less driveable. I wanted my idle to be 11.5-12 but then this happens, when the idle was 10.5-10.8 this happens much less. It ALSO doesn't shut the injectors off on decel and I've tried messing with the decel/overrun settings to no avail if anyone has any tips for that...
On top of all this some info, everything off the intake and throttle is deleted, no ac or ps, maybe I should bump up the idle on the throttle manually? maybe my tps needs adjusted? I was thinking I need to figure out the transient section of the ecu to fix some of these problems.
Got the decel to work, goes flat rich for about a second but then shuts the injectors off. Im happy with that, no more clouds of gas smoke behind me when I slow down!
Mine also goes flat rich when I lift before fuel cut (fuel cut delay is 0). I cant for the life of me figure out how to fix it, I am backfiring huge flames every single time I lift. May be a tps issue, it may not be registering lift sometimes but all my tps parameters are within normal. Very frustrating
Yeah I don't have my wideband hooked up to my ecu.. Pretty new to this to be honest. I need to wire in the 0-5v sensor wire to the ecu? How do I go about that, just attaching a molex pin of sorts to the end of the wire and plugging it in and then configuring it in the ecu settings?

I found the matching O2 sensor plug, crimped that to the 0-5v analog output of the wideband and then plugged that in to the stock narrowband connector. Then you just setup Eugene to accept the wideband input from the stock narrowband sensor pin and tell it what wideband controller you have.
Let us know once you have a log with the lambda trace working, you're flying a blind without it. Fyi I'm seeing some knock in your datalog and your injectors are maxed. The knock could be noise but be cautious.
Oh interesting. I'm also running methanol through a 500cc nozzle. and currently seeing 10 afr in full boost past 4k. But I will lean it out some, I was thinking about changing my primaries to some ID1000s that I have set aside.
I havent touched the knock configuration from the base map that was on the ecu, as well as ignition. What should I set the knock too? Maybe its too sensitive to be useful. Does this function work through the stock knock sensor?
Short log that I hope shows some of the instances of it falling on its face, pulled over and had to adjust fuel map because auto tune took a ton of fuel out of certain cells for no reason and it went to like 16 afr. Turned autotune off and left it on closed loop
This is after hooking my wideband up to the ecu wire for the stock o2. and I put some id1000 in for my primaries, had to add a bunch of fuel across the map afterwards in the cruising cells mainly and set min pulsewidth to 1.512 because I saw that online somewhere. with it set to 0 it doesnt even idle. Auto tune was working at first and gave me a really nice 12.4 afr idle but after turning it off im seeing 11 which im not upset about.
In order to get the car moving from a stop I usually rev up to about 3-4k and I can get it moving, then when the airfuels cut out full lean I can still drive because it just dies while im going 3-4 mph and doesnt actually stall the car. The transient settings are not too far off what came with the adaptronic besides maybe async having a dumb value just because I couldn't see any difference no matter what I set it to.
This ecu file is probably a better shot and I'm driving home with it the way it is now today, turned on adaptive but this time stop once tuned instead of continue tuning. changed a couple things, can't send a new long yet since my laptops dead but it should be pretty much the same.
Not sure if something is wrong with the way my ecu is reading wideband. But adaptive tuning really messes up the map and leans out the cruise cells badly. So I've turned it just to closed loop for now.
A new issue has seemed to arise these past few days, every now and then under cruising conditions no bumps no change in throttle, Ill see a dip from 13-14 afr to 11 or so and I'll hear the engine stumble, like it is missing a spark. Not overly worried about it right now as it happens super fast and it's not like its spiking lean. No clue on that one, think I've read about someone else having the same issue.
Ill try to upload a new ecu file and datalog maybe a longer one tomorrow after class.
Noticed something interesting tonight, my O2 is reading improperly on eugene. at idle when my wideband is reading 11.4-11.9, the ecu displays 9.1 to 9.4 with a voltage reading of 1-1.32v. Seems like the ecu thinks the car is richer than it is.
Have it set to analogue, aem uego 0v-5v. Thats probably my issue with adaptive tuning there.
You're most likely seeing ground offset with a voltage difference like that. Try grounding your wideband to where the ecu is grounded. You can always try changing it to a serial connection as the Adaptronic ecu prefers that.
Changed my wideband calib to innovate: 0v - 7.35 and 5v - 22.4 and this had much less of an offset between afr values about .2 to .5 and it helped with the closed loop and target afrs, not going to try to do adaptive yet.
Couldn't get the spark loss/skip to show up on the log I took this morning but the cars doing much better transient wise, coming from a stop is the worst if I don't rev it up to 3000 it is very hard to get going and wants to die out, free revving theres about a second before it will rev up as it goes lean
Took this on the way home today, at the start of it the spark skip - jump to rich thing happens, and a couple incidents of the lean out when moving from a stop and between shifts.
Your ALG is the same, in many entries of the log there's periods of up to 2 seconds with no data being recorded. Do you have a steady connection from ECU to your PC? Maybe give the internal logging a try.
