Exactly what would a stage 2 set up consist of? More lift? more duration? Or is it like F/I applications where the cams stay the same and we are just adding sometihng more to it to open up more power.

I do believe Malogus is talking about a complety new set of cams for NA that would be very agressive. This would make up the stage 2. He's got my attention especially at that price! My only concern there would be tuning of a set of stage 2s

I hope my car isn't starving for air because I am not just ready to get an IM yet. I installed my catchcan and thanks for your input on that malogus. I did a half-a$$ job on my sparkplugs. Meaning I installed just the front three to see if the car would throw off a CEL on just the back plugs. I resetted the car and drove it crazy for 20 minutes. It drove phenomenal!! No Cel. I gave the car a rest then decided to go to blockbuster again. On my way, I threw a CEL at idle during a long light. The car still drove fine at that time. Another light later, the car went into limp mode. As of now, I have not checked the CEL. I will tonight and praying that the car misfired on the cylinders 1,3,5,; the ones I have not changed.

Canuck03gsr: What spark plugs are you running and at what gap?

Can't wait to see someone running with this setup on AUTO.
 
I'm running whatever plugs came with the car, I guess either chumpion or NGK and stock wires.

I went though a drive thru this morning to get my coffee and sat idling for a long time and nothing. My idle sits at about 800 and is real steady. Actually my idle is better now then before the cams.

Well I've driven my car about 3 hours now and and still no CEL. I popped in at Hyundai this morning to return some valve cover gaskets that I didn't use (wrong ones) and had a chance to speak with the mechanic who did the work. He told me that it was rather difficult to rotate the cam 180 degrees because the number of teeth on the cam sprocket is odd, so when you rotate it 180 you fall between 2 teeth. What he did was compare the set of stock cams with the regrinds and found the tooth that made the lobes line up exactly with the stock ones. He also told me that after the test drive he plug the car to the diaginstics computer and not codes were showing.

Malogus - Could you ask Crower if they see any problems with the reversed cam? I'd really appreciate their input.

I'm also very anxious for the VIM flash....not so much for the fixes (still no CEL) but for the raised rev limiter.

I was also thinking...(I know I should stop right there!) Maybe Skhix is exhibiting the same inconveniences as Supertib due to his air intake. Maybe the CELs are thrown due to a "starvation" of the engine. I just had a look at his mods and he doesn't mention an intake. Supertib was a stock ported intake (like a stage 3) and JackMcNasty I believe was running a stock intake with just intake cams.

Just a thought.
The CEL supertib had was because he had no fuel tuner and his injectors were maxed. This is because the ecu likes to run super rich. Same goes for the other guy getting a CEL with these cams, i'm pretty sure he doesnt have one either. So if he scans the code it will probably say the same that supertib's did.

First off...I ran the cams on the stock IM before my stage 4 upper arrived. No problems at all. I think anyone who is installing these without a fuel tuner is just stupid. My fuel tuner is pulling out 20% fuel across the board practically at WOT. Thats alot of extra gas being put into your engine that isnt being burned off. That right there could be cause for misfires. Supertib ran his for two years with no fuel tuner, and threw all lkinds of CELs. I had a fuel tuner from day 1, and no CELs. Just a thought.

My last comment is....Why would you even consider doing a half ass job on the plugs. Stop being a lazy ass and change them all. I know if involves removing the upper IM and all, but Cmon man, thats just pure laziness. Of course changing half your plugs isn't going to do ****.

Yeah I see that as being a problem. The separation these cams are set at is 110 degrees. Separation is basically the amount of time that both the intake and exhaust are open at the same time. If you are off one tooth either way, you are looking at chaning the separation quite a bit. There are 25 teeth so your separation will be off 360degrees/25teeth = 14 degrees either way potentially. That is going to affect performance big time.

I would seriously talk to rick and work out some way to get the correct parts.....
 
Perhaps skhix is starving his car, but remember after REAL tuned supertibs his next mod was to add the Stage IV IM. I think with his car its a combo of the auto idle, the sparg plugs which look like a junk set up, AND not being tuned which I truly believe is the problem with his misfires. We will find out. I will be running my cams with stock IM's and stock plugs and stock ECU....then I will add Stage IV, denso iridiums, and tuned ECU.
 
I went out for lunch today and on my way home, I through a CEL will I was leaving a slanted parking. I was feathering the clutch and I let me engine RPMS go down quite a bit..

I agree with you Malogus that I really should get the correct cam in there, I just don't want to foot the bill for yet another install.

I have had good communciation with Rick and he seems willing to work with me on this. He's just trying to track down Matt, the other guy who's got a set but he hasn't been around. He's trying to figure out if he has two exhaust cams that are the same or not. It's still undetermined if I'm the fluke or not. Rick also doesn't know why this happen as he did not seperate the cams, that was done at Crower. All my cams did have the same work order number on the paper wrapping that each one cam in, so I don't know.

I also don't want to get tuned yet, because I don't have the VIM flash or the final cam in there.

I know you don't have much faith in the flash, but the car would certainly benefit from a higher rev limiter. I do believe that it can benefit from a good fuel tune too. In the 80 or so miles I put on since getting the car back I've gone though almost half a tank of gas!!! That's not right.

So you are saying you got one cam that is stock and the rest are teh crower cams? That can't be good.

As far as your gas situation goes, yes, it is horrible on gas with the cams in.

No...What happened when I installed is that Rick or Crower (I don't want to debate that) packaged two front bank exhaust cams in my kit. I installed the front bank all was good then did the rear and that was good except the cam was way out of timing ('caue it was the wrong part) , which why I was not making any compression in cylinder 1,3 & 5. I was extremly lucky that I didn't suffer any engine damage here.

What Hyundai did, to get me up and running, was rotate the second exhaust cam about 180 degrees to get all the lobes in alignement, like the stock set-up. The hyundai tech feels it's in the correct position based on a comparison he did but as Malogus pointed out that cam could be out 14 degrees, so I really should get the correct part. I'm working on that with Rick.

I'd like ot reduce the fuel (via the mafterburner) by about 10% (given that Malogus' setup is reduced by almost 20%) until I get to the dyno with final parts. I just don't know if that's a wise move. Opinions are welcomed here
 
That's cause your ECU is running filthy pig rich. lol. I just got off the phone with the mechanic down at the dealership. He says it will be about a week before I get it back. so stay tuned...the rumble is comnig.

Right, that's why I'd like to reduce the fuel 10%, I just would like to know if it's wise doing this blind or I should just stick it out until I get things finalized and to the dyno. And by wise...I realize that tuning bind is not wise, but given the deviation the ECU puts in with these cams I may not be doing much harm.

A week Eh...(see I am Canadian)...I'm anxious for you sh!t to get done and what your gains will be like with heads & all and to see if your results will be the same as Skhix.

....if you go fuel tuner route, definitely get dyno tuned. With the VIM module, eventually we will be running baselines for our cars at dynos - passing off the info to somenoe and get a tune via e-mail appropriately.

Actually once we get the VIM, I still plan on keeping my Mafterburner to dial in the fuel. No ones has clarified any cost associated with tuning via e-mail, so until then I still plan on using the Mafterburner. If all is good after the VIM upgrade then I'll leave the Mafterburner harness on bypass.

Yeah that's definitely an issue, but I know TC at NextGen will be one of the shops that will be able to support and create tunes for the VIM module....which is very reassuring.

Well, I still don't consider myself being stupid, but thanks for your input on that subject. I was being silly when I stated doing a half-ass job on my plugs. I explained shortly after that there was a method to my madness, and it was to hopefully throw a cel on the particular cylinders that I didn't change to be very sure. I did this so that I could let you all know if that was the case. I could have done all 6 just as easy, but I am trying to diagnose as I go. I am definitely not as mechanically inclined as you Malogus. My field of expertise is Electrical engineering, but trying to understand my vehicle as much as I can. I installed these cams because rick mentioned that I will get my cams on the third week of July, and the first week of August he will ship out the VIM modules. That is the reason why I installed the cams right away to see before and after effects of the VIM module. Unfortunately, now rick says that he doesn't have a flash for the 2004 ecu. I am up the creek for a while. I would hate to buy a fuel tuner now, since Rick might have a flash for me one day.

Just to keep you updated, I am not lazy. Out of the three vehicles I own, I bought this vehicle just for the purpose of moding it and learning. It takes alot of researching and studying to modify a vehicle and I understand that. However, my field is totally unrelated and I rely upon others that hopefully don't mind trying to help. Thanks for trying to help so far though malogus. I guess I am tiring you out.

i am glad i did the oil catchcan DIY yesterday night.

Look what I caught today. In about a week, I will have enough to pour back in. :3_winkthu

I finally had my CELs checked, it ended up being 7 CELs. Each individual cylinder misfire and a multimisfire CEL. Thanks to all your help. I realize that I definitely need a fuel tuner. I no longer want to be declared as stupid. Just trying to decide if I should get a fuel tuner now or wait for rick, which seems to busy at the time to respond.
 
I dont think it will hurt to get a fuel tuner. Whether it be a simple one like an SAFC-II or full uot MAFterburner. REason being - if the VIM isn't what its cracked up to be or there is a major issue - your not up a creek. If it is and will do everything a fuel tuner will do - simply sell the fuel tuner and recoup 85% of your cost.

a $500 dollar investment to protect a $15-$20K is very wise....and be sure to dyno tune, not blind tune it.
