New problems...

[tunerangel]

Well now that I have started my car (finally) from the swapp,2 new problems accured. The first one is that when ever i put the stock intake the car works alright but whenever i take off the stock intake and put a spectre air intake on the car turns off. I pull the acceleration string and it backfires and it turns off,why could this be? Also my rpm gauge dont work. Whats the sensor or plug to that so i can check it out? Thank you...

Check the power transistor on the driverside of the block underneath the coilpack plug.it will have 5 wires on a 90 and 7 on 91-94 models

 

[tunerangel]

Well the pwr tran its good. i dont know why it acts like that when i put the intake filter.

 

[MLutin]

Try putting your MAF back on there, plug it in and don't touch it. And go ahead and throw the Spectre away and buy a drop in K&N.

 

[tunethis]

Like mentioned above, put your maf back on and plug it in. The car stalls because you no longer have the maf plugged in. The ecu can no longer read the necessary signals to run the car correctly. No matter what you do, you have the leave the maf hooked up and plugged in.

HaHa like they say put the mas air sensor back on. Did you think that big thing was unnecessary?

 

[tunerangel]

Also it's not a good idea to vent your valve cover. It leaves exhaust gas build up in your head.

So your sayin get rid of both filters and put EVERYTHING back to normal? And no i didnt think it would need it since ive owned a 92 accord and a 95 civic and they dont have to have anything i can just put a tube and a filter and there were done. Its kinda sad how those non tuner cars you can work on easier and this eclipses well known you have to go through lotz of crap.......

Yes, you'll have to take off that air filter because like they mentioned before you have to run your air intake with the MAF sensor and that 'spectre' air filter will not fit right. You need to by an air filter specifically designed for your eclipse. Get a K&N filter, they're great.

As for the little breather filter, that should be fine, but a catch can routed to the air intake is better in my opinion because that breather filter will get dirty and oily over time.

 

[Ahnubus_29]

Wow thats all I can say at first I read this earlier thinking it was some sort of a joke being played on all of us. So after you put the MAS and intake back together how does it run?

 

[AWD_FIEND]

Just some friendly wisdom for a Honda guy, DSMs are inherently alergic to shity parts so as long as you keep your purchases on the straight and narrow you shouldnt have any problems tuning this
"non-tuner."

 

[corsair231]

Cars use two kinds of fuel managment systems. One is speed density such as the Hondas that do not have a MAS. The second, of course, is a mass airflow system. The difference is that a s/d system uses several sensors; ie: map (manifold absolute pressue), tps (throttle position sensor), and mat (mainifold air temp) to determine how much fuel to put into the engine based on a fuel table programmed into the ecu (electronic control unit). The problem with those systems is that they are set up just for the way the car comes from the factory and even small changes may throw the system off. Anything that would skew actual requirements off of the table points will put the engine "out of tune".
M/a systems have most of those sensors as well as a MAS which, instead of just looking up the fuel on a table based on throttle position and pressure and plugging it in, actually measures airflow into the engine to fine tune the fueling. They can add or pull fuel as needed from the base points on their fuel table. The result beside being more accurate is also a system that can self-adjust for mild changes such as better exhaust, slightly larger turbos, intakes..etc.

So Honda tuners pain, DSM tuners pleasure.

Ok also I have another question... My car now doesnt have a cadilac converter nor a straight pipe and i know thats why it takes my 2.0 forever to reach 60. I have 2 options...1 put a converter in or 2 weld a straight pipe. Which would it be better? and will i loose power or gain with the straight pipe??

Without a performance exhaust I wouldn't bother with a straight pipe, just put on a catalytic converter. This would not be why your taking forever to reach 60mph, you have another problem somewhere...

 

[tunerangel]

Hmmm well ill put that catalytic on there... And am preety sure everythings in good condition and hooked up right.... I also changed out ma spark plugs (the new diamond edition) and i changed out all my injectors... to the pink ones another eclipse had in the junk yard....

 

[MLutin]

Is the car 100% in time? I'm not sure on a N/A, but I know if your 1 tooth out of time it'll run like crap. Also did you check the Crank Angle Sensor and made sure your were in time there. Other than that, start breaking it down to fuel lines, fuel filters, and other things that make your car run.

Also, your PCV is there to vent the head of exhaust gas which uses the Intake manifold vacuum to suck out the gases. If you breath your valve cover your PCV valve is useless. Thats why if you run an oil catch, you want a sealed one instead of a vented one. Again, this won't murder your car but it will break down your oil faster and cause some other minor problems.

X2 lack of converter should not slow you down.

Are you sure everything is matched up? You said you have put other injectors in there. Is the computer right for those injectors? Since they were used are you sure they are good?

 

[2gGSXEclipse]

Hondas use MAP sensors where we use MAF sensor mostly because there more accurate and better to use with turbo cars...sencond of all you r CKP (crankshaft sensor) is the sensor that would read your RPMs. i also agree on take the mini breather valve off and put the hose back on that goes to your intake. As far as exhaust i would put a cataytic back on and leave it stock if you only have minor mods with no fuel mapping system

 

[tunerangel]

Hhmm this is all good info. Look someone told me that I have to change my RPM cluster to the cluster that comes in a 2.0 car because the rpm gets its signals from another location. Is this true? And about my car... today I drove it and i mean i stepped on the gas down and did shift good and the car bearly reached 80 and didn't want to keep going up... I think because theirs no catalytic on there to make the pressure the engine needs but i don't know i could be wrong. Also like i mentioned before I took the ecu, fuel inj,cas,harness,coil,pwr trans,from the same car. and MLutin the CAS needs to be on timing to? I mean I just got it and i just bolted on to there and it did turn on fine so i didnt worry. Also the pcv valve is new...

 

[MLutin]

Yeah cause the CAS will adjust your cars timing as far as advancing and retarding your timing. So lets say if it's on wrong you could be running really advanced and it wouldn't match up with spark ignition and so on. As for your Cat, backpressure isn't that big of a factor with these cars (as far as I know). Not having a cat would not make your car act like this. Especially with stock pipes. If anything it'd free up some airflow for you.

ummm...say what now?

 

[tunerangel]

So is there any faqs or walk troughs that will show me how to put the cas? and about my cat... basicly only the headers and the down pipe are hooked. car makes a crap load big noise but wont advance ...

 

[MLutin]

calan, there was a write up on DSMTalk a while back but I can't find it. tunerangel you need a timing light to check to see how advanced and retarted your timing is. But thats what it sounds like to me. Try ajusting it a little one way to see if that improves your situation.

I could be wrong here but aren't pink top's out of the turbo auto 1g?? If so those def won't work I think they are 390's. I think you may want to do a little more research before you tear in to this thing anymore than you have.

 

[Project2G]

It's used to vent blowby gasses that come from the engine. This is all related to ring gaps. If you vent the pressure of these gasses power is free'd up.

That's the plain and simple approach.

 

[tunerangel]

Alright i will. I dont know if this has anything to do but when you turn on the car the first time it shakes and acts like it wants to turn off then after 20 seconds it turns off. I turn it on again and it does the same,but if i warm up the engine and run it for 5 minutes it doesnt turn off anymore. Isnt that weird? and no the pink inj are non turbo and the blue ones are for turbo...
