Major problems

[DSM JIM 98]

Ok guys im going to lay all my problems out because ive been blowing the forums up with my posts and sorry if all this is not in the right section/forum.

I bought my 95 Eclipse GSX a few days ago for 4k which was not a good move because it was very over priced. The guy told me alot he said that it had a a built motor with 272 cams(I believe false doesent idle like it at all), 16g turbo at 17psi(True), and claimed 340hp from dsmlink V2(Feels like about 270-300hp), also said it had aftermarket pistons/rods(I have no idea). When i got the car the wideband was stuck on 14.8 and didnt move which made me curious on how he tuned it in the first place. I drove the car to Mrytle Beach for grad week and the battery died on me. We got it charged at autozone and it drove fine to the beach(3 hours). When i got to the beach i started it up and it started smoking real bad but lessened when it got warm. The idle seems like it is set very low as well. Car drove fine and boosted fine with alittle whisp of smoke when stopping. On the way back home the battery died 5 times and autozone said it was charged making my Alternator the reason. When the car started dying every tac went blank and it started loosing power and bogging out. This is when the smoking started to get worse when we would jump it and keep driving.
I tried boosting it and it would studder under boost and i couldnt make a full pull. I wasnt looking at the boost guage but i think it would still get up to 17psi. The car was running horrible and it all started when the alternator was going bad. Did i flash the tune on the ecu making it run bad and not know what to do or what!

Sounds like the alt is toast like you said. As far as the wb, is it a aem uego? My aem defaults to 14.8 if the sensor is unplugged it may also do it when it's bad but I'm not 100% on that. When my battery was dead yesterday but had enough juice for the dash light and gauges to come on my wb would not heat up so it stayed at 14.8 also until I jumped it off. Jump on you laptop and see if nbs is on, if so it could cause your stuttering problem. I say this because if you wb sensor is unplugged and you are running narrowband simulation, that would mean you have no front o2 which can cause some major afr problems in these cars. Therefore the first thing I would do is make sure the sensor is hooked up, and if so take it out and check to make sure it is working. There is a video that shows how to test the sensor with brake cleaner, a quick google search and you should be able to find it.

Also get rid of the tee in the bov vac hose. The bov should always have its own vac source straight to the manifold.

Not to make an obvious statement or anything, but is that a ghetto rigged recirculator hose from your bov to the intake? If so, you should get it hooked up to your bov. That's just how it looks to me from your pic. Hope you get it running right.

Whoever you bought it from did some retarded routing of wires and vac lines.

So i did ruin the tune by unplugging the battery because it was dead? Also can someone tell me how those lines for the bov are supposed to be because i believe the HKS is vented which isnt good right?

Yes you most likely lost the tune since you have DSMlink V2. Unless previous owner has it saved on his computer, you will need a retune.

And for the blow off valve, the big hose coming off the intake should be connected to the big open end of the blow off valve. Also the nipple on the bov, should have a hose going to the intake manifold.

I couldn't have said it better for your bov ^^ What is it branched off to anyway. Is it going to the manual boost controller you got in there?

One other note, since your bov isn't recirculated, is your intake pipe that goes to the bov at least capped off so you don't have an air leak?

 

[DSM JIM 98]

Yes and it seems that the bov is hooked up right except the mbc is sharing a vacuum line with it the the other vacuum line on the mbc is hooked to the waste gate. I'll take a pic hold on.

 

[spyderdrifter]

There's actually a solenoid below where the MAF sits that should hook into the intake and the wastegate that is a better spot for your nbc, if the solenoid is even there on yours.
