Spoke to Jim Pace GM Performance. They told me that the car will not pass emissions and that the PCM will have to be reformatted for around $500 bucks in order for me to run this cam. The price of the cam kit was a reasonable $450. I was surprised to hear about the computer recalibration requirement. I thought this cam was compatable with stock configurations. This kills me. Did you reprogram you computer? What's the deal?

Thanks.

ASR,
Is your car an M6? If so, then you should not require reprogramming. You may need to drill the throttle body and add a MAFT (I was pretty rich at WOT after the hotcam), but that's about it. If you're an A4, however, then programming may well be needed. I haven't personally taken my car through emissions with the hotcam, but have seen where a couple of others have passed. I would think that it would get by assuming you had the cats in place and the car was sufficiently warmed up. If not then temporarily raising the idle should help.

did you guys not see my post with our hotcam emissions results here in IL!?

it was in the last hotcam thread

I just passed our (IL) IM240 treadmill test with Hotcam at 111* IC last week. Even got a Speed Pass. This is my own A4 98 T/A w/ Mac headers w/cats, etc.. etc..

However, who ever you spoke to IS correct that it is designed as an OFF ROAD ONLY item.

In most cases, in an Automatic, programming is definitely preferable and most will find it as a requirement. In a 6-Speed, most have no problems.

The person you spoke to may have misunderstood your emissions question??? I don't know, however, I hope what everyone told you here helps.

If you have any other questions, drop me an email at JohnSkiba@PACEPerformance.com

If PaceParts.com told you that outright, they don't know what they're talking about.

I cannot tell you the emissions legality of the hot cam. I live in Florida - the basic rule of thumb here is this: if it runs, and you can pay the registration, you can put it on the street. You wouldn't believe some of the junkers I have to share the road with here.

If your car is A4, you probably cannot run the hot cam sans programming. I vaguely remember a few cars from waaaaay back in the beginning when the hot cam was brand new - they tried to run it on A4's with stock programs, and did so with limited success. If I remember correctly, they drilled the throttle body rather large to get the cars to idle without stalling - and that's when the A/C was off. If they turned on the A/C, the cars died.

Now, if you're M6... you most certainly, absolutely, 100% CAN run a hot cam with the stock programming. PaceParts.com didn't know what they were talking about if they simply said "no" without inquiring further into your car's options and what your plans are for it. I've been running the hot cam since 8/4/2001 without a single problem. I installed the cam myself (with a few buddies helping) in 12 hours, and when we started the car up, it started immediately, and found a rock-solid idle that has never wavered since. I have idled in heavy Orlando traffic with the A/C at full blast, and it's never faultered - it idles perfectly at about 750 RPM's with no surge or idle searching whatsoever.

You will occassionally experience the P0300 code - which is completely harmless and does not affect performance. The stock PCM misinterprets the cam's lopey idle for a random misfire. The SES light will come on. As the car gets more and more used to the cam, the SES light seems to show up less, or at least it seems that way... maybe I just get used to seeing it from time to time. If you're careful, and you don't let the car idle for more than 60 seconds at a time, you'll never see the code again. If you ever get caught in heavy traffic, just blip the throttle gently (1000-1200 RPM's is all you need to hit) to confuse the PCM and prevent it from detecting a pattern and as a result, caugh up the random misfire code. I haven't seen the SES light in months.

Finally, make sure the cam is consistent with your overall performance goals. My long-range goal was to make 400 or more RWHP using stock heads with a hot cam. If you're interested in making serious HP above and beyond 400... the hot cam may not be for you. But be sure of one thing - don't just buy it because it's economical - I think it would be better if you saved your pennies for a few more months and purchased a cam more suited to your performance goals than to buy what's least expensive and available to you today. As you can see, from the results in my signature, the GMPP hot cam is a strong bumpstick, and does its job well - and that's on stock programming. And... I have an LS6 intake sitting on the shelf awaiting the return of my Superchips program. With these last two pieces of the puzzle, I believe I'm surely going to make it to my goal of 400-RWHP on stock heads w/ the GMPP hot cam.

It performs well and it's a tad on the conservative side helping to bolster the longevity of the valvetrain's components. I've heard at least a dozen cams in LS1 motors... and my cam is still my favorite.

Hopefully this answers your questions... if not, ask away.

Bluestreak,

Thank You!! I have an M6 and my goals are almost Identical to yours. I can live without 400 ponies but twelves and everyday drivability is a must. Besides, the sound alone that this bumpstick creates is awsome. Thanks again!!

400 HP/TQ at the wheels is good for 11.80-12.10 if you can get your 60-ft times in the 1.7X to low 1.8X range. I have a good buddy with a very carefully engineered, well-built blown LT1 who's pushing 391/385 at the wheels, and he's consistently running 11.8x w/ a 1.77 60-ft.

If you're going to run drag radials 24/7/365 like I do, just be careful with your rear axle setup at that point... be sure to get a girdle with the main bearing cap studs.

I think I can live with that kind of performance as well, my friend. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

The hotcam is a great deal from pace. I got mine
from there..
Get it , install it like this
http://www.ls1info.com/article.php?sid=49

I have my throttle blade drilled to 15/64"
I have the 'Tropper Mod' which is a .022"
spacer on top of the idle setscrew to kick
the idle up just a tad..
Emissions.. I dont know.. but I will find out
in oct.. TEXAS is going hard inspection here in
dallas area MAY 1.

i have pulled 365 RWHP and hotcam WILL pass emissions, but it is lumpy and sort of a headache when it comes to everyday driving (by the way, i do). i have only run my car one time so far on this set up in VERY VERY poor weather with stock rev limitor. my time is in my sig. if i can work on the launch i should be very low 12s and i dont have mods like pulleys and weight reduction. i love my hotcam for the sound but there are many cams that outperform it. if i had my choice again i would go with an MTI-like grind. i am about 12-15 RWHP short (no biggie to me) but lacking good idle. muscle car guys love it though! maybe that is worth it.
