I am going to say no to the seafoam, b/c I am not sure what that is. As far as maint. I just changed all the fluids, plugs and wires about a month ago.

I have been trying to run this electrical problem down for a week but I just can't seem to find it. I know there has to be a short somewhere be cause it happens at random times.

The car runs good til my tach starts jumping around then I get the misfire code. While the tach is acting up it goes to 0 then whenever I press the clutch pedal it jumps up til I release it again then back to 0.

It is really weird. Any help would be great. I have posted a couple threads on the forums but I can't get anyone to chime in.

Ah. Well to clarify, Seafoam is a petroleum-based treatment used to clean out and remove built up deposits and gunk in your motor [intake, valves, etc.] and even your fuel system.

If you think that it's a short, you should test for continuity at each sensor/component's plug or harness.

Other things to consider [some of which you have already accomplished]:
-ECU
-PTU
-CAS
-CPS
-coilpack
-plugs
-wires
-boost/vacuum leaks

I'll post more when i get home.
 
Well I found the short. It was under the dash near the ECU. Where the previous owner had something hooked up the removed and then pushed the naked wires behind the ECU. I covered all the wires and no problems so far. :pray::thumb:

Where can I get seafoam and is it just a pour in application and go, or is there more to it than that?
 
keith,

im out of town til early june man, i saw your text i just wasn't sure who it was. sorry. alex is always swinging deals, im sure he can dig up a tdo5 wga for you if you really need one.

call me corey btw, gofer is just a forum name... :thumb:


:dsm:

Haha yea, sorry it's a habit, on the other forum they ONLY go by their forum name...

also, I'm not in a rush to get the wga.

Good deal! Hopefully that was the culprit.

Here is a how-to video on youtube posted by a 3/S owner. It is recommended to perform the treatment towards the end of your oil change interval as to not waste the oil; it will thin out your oil. I've personally run a second treatment at the immediately following oil change to really clean things out. You don't have to drive your car to blow the crap out. In fact, many people suggest just letting it idle. Also, any vacuum line will work for the intake. I tilted a cup and let my manifold's dedicated BPV/BOV hose suck the fluid instead of pouring it down the brake booster line. The results are definitely real.

Lastly, you can purchase it at any local automotive store [i.e. Autozone, Kragen, Pepboys, etc.] Good luck!

PS: You can help keep things clean afterwards by running a single/dual oil catch can setup. People who run E85 or alcohol/water injection usually keep things clean anyway though.
 
Thanks, I just got done with the seafoam treatment and man it does make a difference.

Now I've got to get some tuning help. I have a half ass tune, but doing a third gear pull at 5k I loose all power. It pulls hard as hell to 5k then nothing all the way to redline. I would post a log but I can't figure out how to put the graph from ECU+ on here. Here's what I got though:

My AFR's are 10.5-11.3 from 2500-5k then they lean out 11.5-12
Timing: 2k-4400 about +15 by 5k +2 and bottoming out -1 at 5300 and steady +2 to redline
Knock volt: I get a spike in knock at 4250 and 4500 1.9 then less than 1 to redline

:confused::confused:
Can anyone figure this out?

There is your problem bro. [What's your name btw?] You're pulling way too much timing advancement up top and, thus, are losing the power. You're only getting a small knock count of between 1-2, so your ECU is supposed to continue advancing timing. The only other reason left is that you don't have enough injector to work with. Your TIMA will be pulled based upon load amount [INJD/IDC's]. How many pounds of boost are you running on your S256 Bullseye? How is your fuel pressure looking [if you can monitor it]? Perhaps the Walbro 190 isn't sufficient. Have you hot/rewired it? Just providing a few things for you to ponder and take into consideration.

~AL

PS: Did you enjoy the free smoke show from your car? hahaha.

PS#2: I just ran a quick search, and you're running quite a larger-sized turbo there buddy LOL. For everyone else to see:
You must be logged in to view this image or video.


You'll either want to lower your boost level, tweak your methanol injection, or upgrade your fuel system further [i.e. Walbro 255lph, AFPR, xxx injectors]

what's up guys?
well i had no luck with getting another dsm for reasonable price and i bought a 4g eclipse for a good price. Man the only eclipse i liked were the 2nd generation but i have never seen a 4g in person they have a beautiful interior and they are pretty fast. I got the the GT 6speed 263 hp. i signed up in that forum but it's not the same like on here ROFL
I'm still looking for another dsm though:thumb:
 
I think I found part of my problem. I took my meth nozzle out to make sure it wasn't clogged. I straight wired it and found that it is leaking pretty bad at one of the quick diconnects. So I'm gonna replace that tom and see how that affects it. Also my 190 fp is rewired and the only reason I haven't gotten bigger inj or another fuel pump is because of the DSMChip that is on the ECU. I just bought a stock EPROM chip that sould be here this week so I will be able to tune correctly without having to figure for that chip. I am running 23 PSI on that turbo. I do know that I am limiting myself with the current fuel setup but I should be able to correct that soon. I am planning on 255, 850 inj, and afpr. I think I'll be a whole lot better off when that gets in.

My name is Matt by the way, what's yours? You seem to know alot about tuning if you got the time I could sure use some help from someone that has more knowledge than me. (which isn't much):thumb:

If you think you may have a chance to come up this way PM me and we can work it out. I'm off work all this week and half of next so anytime in there is good for me. I just want to get this thing running safe for now til I can get the fuel right.

Thx for the input:hellyeah:
 
george - Congrats on the 4G! At least you have a newer and more up-to-date car w/ less headaches right? Post a picture or two if you get the chance.

Matt - Hey! NP man. Btw, my name's AL:) I had a feeling that it could have been related to your methanol injection! I also totally forgot about the chip that's burned for a certain injector size:ohdamn: You're able to datalog, correct? The best way to decide if your current fuel setup is adequate is if your IDC [Injector Duty Cycles] are around 80% at WOT full-boost. Pushing them to 90-100 is maxing them out and anything over is just overheating/loading them. Your methanol injection is really helping you out [I wish I had water/alcohol injection... =/ ]

I am still learning myself, but I've been able to tune my VR-4 and help many others out. I wrap up my finals this week and will be putting back together my car + retuning as well, so next week is a possibility to meet up! I'm not sure how far away you are though LOL. Just shoot me a PM if you would still like to meet next week.

Good luck fixing the small problem!

Cool vid, PM'd

VergeTSi-pm me because i really want a project car the 4g is running so that leave me with nothing to doROFL

I know all the machine shops up here are back logged about a month. There is one pretty reputable one in Oceanside called Smokey's if you want to give them a shout.

1602 S Coast Hwy
Oceanside, CA 92054

I drove up to Camp Pendleton to meet Matt [MilitaryTalon] this afternoon. He has a badass, balls-to-the-wall Talon w/ its 23 pounds + methanol :cool: He also has an awesome kid and wife haha.

I must admit that tuning w/ an EMS was a great experience! It was my MMCD datalogger + AFC + so much more all integrated together! He's definitely on the path to building a 10 second monster. Good luck bro!

Here are a few pictures:

is that a stock exhaust on that thing? Sonic, looks like someone else keeps it stock like us. I bet they arent even runing nitrous like us though. Us vs Them mentality activated. LOL I kid. Anyway, I was going to drive to California Speedway for the drags today and once i get to the onramp by my house I got a check engine light P1400 ! ugh ! So i turned around and went back home = ( I totally forgot i had a dsm for a few weeks problem free till this typical ''problem out of the blue'' cames along. LOL There should be a reality show on MTV titled ''I own a DSM.. FML !''
 
It's not a stock exhaust it just looks like it. And just to clarify I don't have EMS it is ECU+.
I really appreciate the help AL. It makes things so much easier when you have someone in the passenger seat watching everything. Hopefully I can get this thing dialed in soon, I can't wait to take it to the track.
 
I also see that you have painted your door trim and have managed to keep your fog lights with that fmic.. what kind of fic is it? spearco small core from RRE?
 
Yeah it is from RRE. And for the window trim I need to replace it it looks nasty right now. And for the foglights I have been looking for a replacement for the passenger side but I have not had any luck yet. If anyone knows where one is please let me know.
 
nice 2gb talon... don't know how you've stuffed that monster turbo in you're engine bay but it works! you could probably advance even more timing if you had a bigger FMIC as well, colder air = less knock.
i see a lot of new DSM's on this thread we need to get another meet scheduled and get a pre MOD'09 head count (car count) so we know how big the SD DSM van pool is going to be going up to Cypress in a month. :hellyeah:
alex you need to find a machine shop quick and get that car in race condition again so we can run them at racelegal before i deploy. I still want to get you from the dig before you talk yourself into doing the AWD swap.

anyone down for an early/mid june meet? we can keep scheduling them around the racelegal dates like we have been but the turn outs have been less than impressive because its a friday night. most only have fri/sat night to put their game faces on to party so im thinking a late morning/early afternoon on a sat. or sun. for a few hours and then a bite to eat somewhere wouldn't be a bad idea?


:dsm:
 
i think you'll find exactly what your looking for here...
2G DSM Window/Door Trim

as for the fog lights on a 2gb talon your best bet would be to trade me your bumper for my bumper and my fogs? :D


:dsm:
 
What up Corey,

Oh yeah, meet would be nice. Im in. When you going to be here again Corey? I think Im going to end up grabbing that GSX from Alex and just putting the 6 bolt I have in my storage in there. Let me know, maybe with all of us getting on it we could have it finished in no time. Now Im just hoping that motor I got off Mike is good. If not Alex and I are going to be knocking on some doors.:mad:

Let me know, that goes for you to...

Moe, Ill talk to the wifee for you.
Mike, you need to bring the bbq stuff cause we still have not got it going.
and Alex, well we dont really need Alex to be there, just leave your front gate unlocked!!!LOL

But for reals guys, Lets see if we can get something going soon and get that 1g up and going. Let me know if you guys have some time. Get Rego over there too. Food and Drinks our on me.:thumb:
 
I am def down for a meet sometime. I was going to go to the race legal next weekend but our Battalion is having a function in Primm on Fri so I won't be able to go this time. I do know that the 29th is suppose to be Military appreciation day though. I think if you have a base sticker and military ID you get in for free. At least that is what the inspectors were telling me last time. That's just FYI for all you fellow military types out there. That gives me time to get some more fuel for my car though.
 
Put me down for the meet, as long its not this weekend cause im working.

Rene im down to help you out with the 1g, just let me know when you want to do work.

hey MILITARYTALON i have the talon fog lights, i had to remove them when i installed my fmic. Let me know if you still need them.
