from my experience when increasing the injectors you always have to add FV offset. if you idle arround 14.7 then the remain columns will be rich and you will have to decrease fuel.

I have tried just running open loop. It'll still do the jerking on openloop. I actually started using the wideband as closeloop not that long ago, I was using the stock 02. My thoughts were that maybe the aem wideband would make the car stop having that one specific problem, but it makes no difference. Runing openloop made the car idle too lean(iat heatsoaking). I even relocated the iat if it helped. Runs smoother, but problem wasn't fixed. I tried way too many setups. I don't know if maybe my settings should be changed, but a lot of parameters under settings are new to me, like overlay afr, mostly all of them. That is the last spot I can think of. Ill be calling relic1 later this week to see if he is kind enough to help me out. Any other opinions as far as settings? Thanks....

Actually the car running 0.0 offset idles well. Afr's are steady, that's why I never thought of playing deep with that table. I'll try it today.......

1 thing is very important when you want to change tip-out and thats the first column. Imagine that if the first column (which its reading off throttle until fuelcut begins) is way too rich, you can set -50% tip-out without any reaction. Tune the first column!

! Tip out is not the issue. relic1, one of the forum users, met up with me and gave me a hand trying to figure out why the car does this. He was of great help. Told me of a lot of things I wasn't aware of. Like the fact that not updating windows might make ectune run iffy. I ran the car with a new calibration using crome, and the problem completely went away. It took me maybe 20 min to do a new cal, and the tip in jerking issue was non-existant!!! We thought that maybe because I had not updated windows in a very long time, that could cause my ectune to freak out. He looked at my cal, and nothing seemed out of the ordinary. As soon as I got a chance, I uninstalled ectune, updated everything possible, and reinstalled ectune again straight from the website. Made a new cal, tuned afrs, everything looked good, and BAMM! Nothing got fixed(except my laptop is running a little faster now!). Tried many different setups, but I can't make it to tip in smooth. Car runs better, but not as it should. relic1 was in the car with me, and he felt the tip in jerking as well. It's not horrible, but it will get harsh sometimes. He even adviced to it being related to a mechanical issue, but we concluded that if crome ran real good, then it couldn't be that. Any other opinions? Has anyone else had this happen to them? I'm at the end of the road, don't know what else to do......thanks........

some notes: the jerking happens more at lower RPMs. it's VERY annoying below 3k, it's almost like the rear mount going bad, that clunk you'd get if the engine moves from one end of the bad mount to the other end. RPM and VSS don't show any dip or spike. He does shift a lot sooner than I would, often below 3k even in first. I don't shift that low so honesty I'm not sure if my car does it or not. And the weather is not being nice enough here in chicago to drive my car to see if it does it with mine. It does it when rolling on the throttle at a constant RPM, off of the fuel cut. In any gear, but more noticeable in higher gears. Unfortunately I didn't bring my ostrich to try my license on his car. (I have a feeling that may violate the license agreement though) But then again our setups are close enough that we should be able to swap in my ECU/Ostrich/cal into his car without modification. thething96: If the weather is decent this weekend, if you're up for it, we can try this.

Sorry about the late response, been real busy......

Of course! That would be awsome! Let's hope this weekend is in good shape. But I have a feeling its going to probably snow. If it doesn't, then it's a deal....Thank you.....

Have you tried playing with the tip in ignition adjustments? Might be worth a shot.

thething96 · Post by **thething96** » Fri Dec 04, 2009 12:48 pm

Yeah, I've moved the tip in ignition every way possible. Adding, subtracting. I even disabled it( and by disabling it, I mean making the min. coolant temp at 220 degrees, 500-600rpm range only). Even if I leave it as is, or move stuff both ways, it doesn't matter. I even thought that maybe iacv % cycle might make a difference, but even a -30,0, or 50% cycle, it's still the same. What bothers me, is that crome doesn't do this. Granted, both programs are very different, crome tip in is as smooth as stock. We'll see this weekend. Hopefully everything wiil get figured out....

Did you get your battery offset tables tuned out properly? I think I remember you talking about it; I wouldn't take the belt off, I would just use Burgermass's method and just un plug it.

thething96 · Post by **thething96** » Sat Dec 05, 2009 11:37 pm

Yeah, unpluging the alternator would be easier. The offset is pretty good. It has steady idle afr's when going into different voltage. The way I did it, is at first, let the car idle with no lights/radio/defroster on. When afr's are good, I'll turn on the lights. When that's done, I'll turn on the defroster. At last, I'll hold both window switches to make the window go up, and I ended up with around 12.30 volts, with all power on. From 14.60 to 12.30 volts, afr's are good. Haven't tried anything bellow that. Second on my to do list...

Well, winter has officially started here in Chicago, and let me tell you, this whole tip in jerking issue is completely f**king BULL CRAPP!! I was stuck on traffic for about 45 min. The whole time I was doing like 5-10mph. The car jerking every 10 seconds for 45 min. has to be the worst type of torture I have endured with this car. I'm hoping we won't have snow this weekend, maybe by then issues will get figured out, but until then, I really don't want to drive this POS jerking having Integra. Don't really want to run crome, but might have to.....

So, after an hour or so of testing, relic1 and I came to a conclusion. The tip-in problem is NOT ecu or software related! We swapped ecu's and my car had the problem with his ecu, and his car ran smooth with my ecu, so I'm out of options here. Being that I already changed map and tps sensors, I don't know what else to change. The only thing I'm going to change, is the injectors. Currently using rc550's, going back to stock to see if it helps. Never thought of any other reasons as to why the car does this, specially since crome doesn't do it, but could be because they're different programs. One question is, what do you guys usually have your map sensor voltage with koeo. I noticed while datalogging that I'm sitting at 2.86v, and the stock map is scaled at 2.90v. I did adjust the map sensor screen to be at 2.86, and noticed the tip-in jerking drastically reduced. It actually has the issue at very minimal throttle, less throttle than before. Just wondering what voltage does everyone have their map sensors at??? Thanks....

the MAP reading with KOEO would be a measurement of atmospheric pressure. Think what pressure is actually inside the manifold at that time and it makes sense. As a result where you're located and the weather that day is going to change that reading.

Post a log and your cal again.. I will look at it today.. I have an idea why its doing this but I need to see a log where its happening..
