I just installed my 2.9" Intense pulley, and also a set (4) of NGK BK7REs gapped to .35
I dis-connected my negative battery cable before doing any of the installations so the PCM would have more than proper time to reset.

After the install I re-installed the negative battery cable, and fired the car up to let it idle for a few moments before taking it for a test drive. (Also to make sure that I had the belt properly alligned, and everything tight and etc.)

Im not really sure why the CEL is on, however, I have my assumptions about that vaccum hose that connects to the battery (gray color). Its come loose before, and caused a CEL. It popped off when I disconnected the battery cable, but I did NOT run the car. I simply put it back in place, and went about my business.

The only other thing I did, was when re-installing the boots for the sparkplugs, on the one closest to the fuel line, I disconnected it from the harness, to better re-install it after plug installation. After it was settled on the plug, I re-connected the harness to the plug boot.
Beats the heck out of me. Im not in anyway new to working on my cars, and I don't think I F'd anything up. Perhaps the CEL will go out. If not, it will be corrected Tuesday 10/10/06 when I have Stage I installed.

Suggestions, Guesses?

Thanks,

For the time being take it to an Autozone to have it scanned and find out what code you're throwing. I'm sure someone on here could look it up if you got the code.

Either way, have them clear the code and see if it comes back on your way home.

 

Umm, I think it will go away. In my opinon, I think you're throwing the lean code. You unhooked the battery (which I never do) and it resets the computer. As soon as you hook it back up and start the car, it cycles through and still thinks you're running a 3.4 inch pulley. I don't know how to explain this but I actually think it's better not to unhook the battery. What i mean is that if you just install it, it takes time for the computer to go through its next cycle. By the time it does go through its next cycle, I think it adjusts itself to the pulley (of course if you put a 2.8 on there on a stock tune and injectors u will get a cel because you are definately running lean.)

I have an off topic question though....Why are you buying gm stage 1 but have hp tuners in your future plans as well? To me that seems like a waste of dough.

 

why did you gap them at 35 with only a 2.9" pulley.

 

1.) Yea, I know that a 2.8" and stock injectors is going to run lean. Im running a 2.9" There are a few guys running a 2.9" stock w/o issue, so I decided to toss it on there just for the hell of it and see if I get away without issue as well.

2.) I gapped them to .35 because thats what most others have done, no other real reason. I believe thats what Denny gapped his to when he swapped in the 3" pulley. Do you think I should have went with .40 instead?

3.) HP Tuners is probably not going to be a anytime soon investment. That will most likely come after 60lb injectors, and other supporting modifications. For now GM stage I will be the only tune I will be running. Mainly because I got it for uber cheap IMO. ($370)

4.) I was thinking of going to Auto Bone and getting them to scan it so I could get the code and have someone relay to me what it was. I'll have to do that sometime tomorrow and get you guys the results.

Thanks for your input. I'll let you all know how it turns out. In the mean time, Ill try not to lean it out and blow it up like my old RX-7 ....

Has your CEL gone away? I always throw one for short term memory loss when the battery is unplugged

 

Yes my CEL has went out. I went out this evening and drove over to a friends, when we left his place it was out. Went out to Boardman this eveing to dick around, nothing really going on.

Met a random new Civic SI out on 224. I was in 2nd next to him and gassed it a little to get his attention. (Im hitting 15psi no problem). He seemingly had no interest of racing me at all. We got down on the lower setcion of 224 near the boardman plaza. (Where all the cops usually are, awesome). We happened to get next to one another at a red light, and I pay him little to no mind, but anticipate him taking off just in case.

We both come out of first gear into 2nd at a low RPM, then in 2nd he cranks into it, so I do as well. I totally kill him by a car lengths up to 70-80mph then let off of it as he stays on it, then lets off. I follow him so I can turn around and park where my friends are hanging out, get next to him and wave "hi" as a gesture of good faith, and am on my way.

I try not to be a **** master when I go up against someone, and hope that they would return the favor. I guess it was a given that I could take him, but it was at least something different than the hum drum up and down driving on 224.

Chris-

 

Anyone have any opinions on either of these two other issues by chance?

Thanks,
Chris-

 

Since you're only hitting 15psi of boost you should be fine for a bit, just don't run the breath out of it. Those injectors are maxed out at that level of boost, and with it getting colder your chances of running lean only get greater. Get GM Stage 1 as soon as possible.

As far as your plug gap, that's really up to you. When I had my stock injectors and tune with my 3" pulley I gapped them at .040 and it was great. .035 is going to stop the spark from getting huffed out, but you shouldn't have that problem at 15psi.

 

Yea, I figured that it was probably running a tad on the lead side right now with the 2.9 on there. I don't crank on it that much, if anything I spend most of my time trying to keep it out of boost to save on gas.

PS-Im considering selling the stage 1 kit off right now though, and just getting HP Tuners and 60lb. injectors and the harness kit, then doing a custom tune. This way I can upgrade to a smaller pulley setting in the future, and have the benefit of a "custom" tune. Seems more financially logicaly at this point. I can always swap my other larger pulley back on until then just to be safe.....

I thin that covers everything guys. Thanks for your input.

Well, without a code I have no idea where to point you, but if it went out that's a good thing. You may still be able to pull the code even know it went out. What ever it was, I would be careful running that setup until you get the Stage 1 flash or tuning.

 

Not really concerned about the code right now since it went out. It came on after just starting the car, not after driving it with the 2.9" on there. Perhaps it was the memory issue another member suggested.....

waylin22 and BlueSS-supercharged both ran a 2.9", I know BlueSS ran it without anything else, just stock, and both had no issues. (not sure of their AFRs, etc.) Im sure there are others who have thrown a 2.9" on there as well. Todd at INTENSE warned me against running the 2.9" on a stock setup, saying it leans out on top end therefore I got a 3.1" and a 2.9" at that time.

Im slightly concerned about it since I don't have a wideband to really monitor my AFRs, and because of the various opinions concerning this setup. I just don't see what the big difference between a 3" and 2.9" is. Others run a 3" on a stock setup and say thats fine, but that a 2.9" is pushing the limits of the stock injectors....

MY PLANS AS OF NOW
Stage 1 goes in Tuesday, perhaps for Christmas I'll get HPTuners. I don't have enough experience at this point with engine management to go getting HPT and 60lb'ers and just going at it. It may be a waste of money, but thats just where Im going to go with things for now...

Chris-

 

Big difference is .1". Hell I knew a guy that ran a Billettflow2.7 on stock injectors. Would I do it? Hell No. Do you have an Interceptor or some way to watch for knock? It is a neccessity in my mind.

 

ya iv been running that setup for almost a year now, no problems at all. never had my **** checked out but i dont think im damaging any thing. no problems and no other problems i want to get some things tested but im not gona stop running this setup because i feel its hurting

 

no cells, no bogging, no nothing.

 

No, no gauges to monitor anything. (Real good tuning, I know, haha). Im going to keep stage 1, and have it installed Tuesday.

Maybe for Christmas or something (birthday and christmas fall in Dec.) I will get HPTuners and tweak GMs tune as a learning curve for myself. (Run a 2.7" at that time as well). I don't have much experience with PCM tuning, so Im leary of attempting it myself and really pissin' something up. (even though you can reflash to stock and all). It may cost more in the long run, but thats how its going to have to be for now....

I read a post by a guy who ran a 2.7" or 2.8" on a stock setup and took it to the track. I would definately be learly of that....

I think I'l be more than fine till Tuesday, the car doesn't get driven that much as it is, when it does its just a commuter or weekend car. Im just anxious to see what the performance gains, if any, will be gained by the GM stage 1 tune with the 2.9" on there....
