So, I got my 20G installed, still havent modded the injectors or gotten a intercooler yet, but it's running about 10psi right now, with a stage 2 basemap.

When I hit the crossover point something very odd happens though, the AFR goes super rich, I can tell because the car "floods" itself and pours a bunch of black smoke out of the exhaust. It did not do this with the stock turbo... What could this possibly be, and how can I fix it?

Once I get past the crossover point though (slowly), it'll pull to redline. Kind of odd.

here's a video http://users.zoominternet.net/~gmtarkin/whatsthis.avi

Thanks!

Post a log. Easy answer is - if its too rich, lean it out.

I'll get a log a little later today.

Just wanted to update this a bit, any time before 5k rpm's if I hit full boost and over 50% throttle, it's as if I hit a rev limiter, which can be seen in the video.

Could this be overfueled? since I am running the stage 2 basemap, maybe the map is too rich below 5k? set for a turbo that would be spooled by then?

It's really odd to say the least. Once again, there is no knocking there, so I don't think it's too lean.

....since I am running the stage 2 basemap, maybe the map is too rich below 5k? set for a turbo that would be spooled by then?....

That's not how it works. The utec fuel map is based on load. This means that if ya run a certain boost, the utec will take a given fueling offset from the map for that boost. Your turbo just won't be getting fueling offsets from the higher boost ranges of the map at early rpms cause your turbo will never get to that boost at those rpms.

Is this on a wrx or sti? What are your other mods? What utec firmware version are you running, and are you using utecs olf mode? How to you hold the boost at 10psi? I've never heard of a 20g with such a low wastegate pressure......

I have the UTEC rev 4.2c, full turboback, uppipe (all catless) txs bov, perrin short ram intake and IC pipes, grounding mod, knife-edged throttlebody

This is a regular WRX

The boost map is set to "1" in all columns (to keep it low and safe) and this is working in conjunction with the ABC, just keeping the boost low and safe until I get my stuff together

I don't quite understand why the IDC section shows ---.- at some points... (usually the points where the anomalie occurs.)

Could the wastegate be trying to fight the solenoid and cause it to flap? it's a very odd sound, once again, the video of the occurance is
http://users.zoominternet.net/~gmtarkin/whatsthis.avi

I have 1 set to every column in my boost map, except the 0% column.


hmm, kind of like the wastegate spring wants it to close until 15psi, and the controller wants it to open earlier... and they fight, until maybe the boost gets high enough to the point where the spring doesnt have enough pressure to win against the solenoid. I'm not very knowledgable about how wastegates or the control solenoid works, but I think I have a relativly decent idea of it's operation. I could be way off on this. It would make sense though when the boost gets up past 11 or 12 or so, then it'll carry itself up to redline

Your IDC column is showing ---.-- because your maxing your injectors out. If I'm wrong, I'm sure someone will correct me, but if you look at your IDC before the sections showing ---.--, you'll see your injectors flowing ~97% and higher.

Even at 10 PSI, the 20G is flowing a lot more air than the stock turbo. If you're going to mod your stock injectors or buy bigger, you need to do it ASAP.

I'm gonna do it this weekend most likely, or maybe sooner. I've looked at the job a bit and I think I can handle it now, it looked like a big bitch, but it doesnt seem too bad anymore, and I'm no longer dreading it, but it definatly wolnt happen tonight as I pick up my copy of Battlefield 2 after work, and that's gonna suck up my time, heh.

Maybe I'll get to it tonight, but probably weds. I'm just wondering why it's doing that odd burbling/stuttering/hesitating thing. But I'm almost dead-set on it being the wastegate solenoid and spring fighting each other.

maybe running way too rich. you have black smoke coming out the back? why are you running a 20g on stock injectors? stop that!

I get scolded when asking for a diagnosis, wonderful, I already explaind about the injectors, and it's coming within the week, it's not like i'm running 20psi after putting the turbo on with no supporting mods.

I asked for help, not to be bitched out, I said the injectors are coming, but people refuse to see that. I KNOW. It's being taken care of, I just want to know why it's doing what it is, and if it could be because of the injectors, or what else it could possibly be.

I would fix the injectors first since they're *definitely* a problem.

I can't watch the vid since I'm at work, so I can't really offer any advice as to what the sound is. It does sound like misfires though, which can be caused by running super-rich. Or a bad coil pack. Or a marginal spark plug. Or a boost leak.

Do you have access to a wideband?

My friend has a techedge, but he just went on vacation, so I can't get a hold of that for a week or so. I think i'm gonna order a step colder plugs, mine are probably about due for a change anyway

Does a misfire throw a code? because I scanned my codes the other day and had nothing in there about a misfire.

#1. I wouldn't mess with fuelling unless I had a wideband
#2. Put injectors on before turbo, not the other way around
#3. Don't ask for help uless you can take some constructive criticism
#4. Don't drive your car right now

Just called my buddy, gonna get his wideband for the next week ro so while he's gone, gonna cut my injectors tonight I think, definatly by tomorrow though.

Question, can I run without the narrowband sensor (the second o2 sensor, right?)? or would I have to set up the narrowband emulation for the techedge?

How sure are you that you have 4.2c and not just 4.2? It's kinda hard to tell if you're never seen a 4.2c screen because with 4.2 there is still a (c) after it which is a copywrite thingy. There was a problem with 4.2 that when the injectors maxed out, sometimes it would create a misfiring condition. This would explain all the black smoke. Do you get any misfire ce codes? I would also guess that you're running pretty rich since I've seen stage 2 wrx's run maf voltages of 4.2 and not max out their injectors, but your injectors seem to be maxin out at 4.1......

peace

No misfire CEL codes... I'm almost positive I upgraded to 4.2c though, I may have not, but I'm pretty sure I did.

I guess I could give it a reflash attempt.
