Hey guys I just got done running some autotap logs after installing my cam and hpp3, I ran it with hpp3 tuning/then stock tuning. I found some interesting results,, 1. I really have to mash my pedal to get full 100% throttle open and 2. that stock I run a little rich but with hpp3 I am right in the "hot zone" with my o2's and air fuel ratio,, I was thinking it was faster maybe smoother with the hpp3 before the atap but now I actually believe it is running better with the hpp3 tuning,, I had no Knock Retard stock or with Hpp3,, and also I can see where the hpp3 advanced my timing by about 2 degrees on average. All in all I'm pretty happy that my car is running ok and it seems that the hpp3 is helping me performance wise but now I have to get to a dyno for the real test. See rest of mods in sig at the time of testing.

If anybody is interested here is the data I collected with hpp3 tuning and then stock tuning.
-------------------------------------------------
AVG B1S1 with hpp3 .885

AVG B2S1 with hpp3 .899

KR 0 degrees with hpp3

AVG Ignition timing 25.4 degrees with hpp3

Engine coolant at 176 degrees with hpp3

Ltrims right around 0 while cruising with hpp3

-------------------------------------------------

AVG B1S1 with stock tuning .906

AVG B2S1 with stock tuning .917

KR 0 degrees with stock tuning

AVG Ignition timing 23.2 degrees with stock tuning

Engine coolant 176 degrees with stock tuning

Ltrims right around -4.7 while cruising with stock tuning

Interesting results. What year is your car? Looks like maybe an '01 or '02 from the low timing advance (when compared with pre '01).

yeah its an 01 also I forgot sig..

I have a 98 and lost HP on the dyno with the tuning. We did 3 runs with it and then took it out and did 3 more. I gained 4 - 8 HP and 5 - 12 TQ. I only had some free mods Lid, pulley and open Borla. I don't have A-tap to take reading. I left the HPP3 tuning out.

Seems to work for some people. The power tuning pulled my 02s down from .88x - .89x into the .87x range and I picked up a lot of KR. That was in the summer, haven't tried in the cool weather.

Do they have HPP3 for 2K2 cars yet? I havent seen it if they do. Thanks.

I've heard the HPP3 will be out for 2002 cars around march.

I can back your results as the same thing happened to me. Leaned me out a little and I gained a tenth or 2 and 1MPH. Tested it at the track on the same day. <img src="gr_stretch.gif" border="0">

When my engine was stock, I picked up a fair amount of KR with HPP non-rfg tuning (no rfg on 2000 HPP).

Then, I installed my MTI T1 cam setup and discovered that my car ran horribly rich with this cam and Mac off-road headers. I was at like .975 O2, and timing was terrible at like 24-25 degrees or so under WOT. Once I re-installed the HPP non-rfg tuning, my O2s went down to like .935 or so, and timing went up to 28 degrees or so. Quite a difference.

Anybody have a clue why the hell the installation of a T1 cam would make the car so damn rich in the first place?
