...Well, not that I really use it for tuning, but it does work well for global HP measurement.

...And today, with almost a perfect/beautiful launch (best one I have had), revving to 4500rpm in first, and 7,500 in second, I was able to hit 296 HPs @ 6,400 , staying basically flat to 7,300 rpm.

Mind you that I make my runs in only two distinctively flat places, in only one direction, at starting precisely at the same place (there are visual clues/signs at each place).

Today's temperature was around 65F at 1:40pm EST, medium-to-high humidity, and location is South East FLORIDA (Broward County). Fuel is 93 Octane Shell, with 60% of tank capacity.

What was striking to me, indeed, is the resulting torque curve: maxed at 4600 rpm, and literally FLAT (-8 lb.ft variance) to 6300 rpm. No spikes, no humps/bumps, smooth as my son's cheeks. Probably my hybrid boost control setup is resposible for the smoothness.

For those who may ask, my current set up includes:

-Ultimate-Racing 2.5" DP
-Ultimate-Racing 3.0" cat
-Ultimate-Racing 3.0" turbo-back

-XEDE management (with custom boost map)
-TurboSmart MBC (in conjunction with XEDE for maximum
output/control of wastegate duty cycles)

-K&N drop-in Filter Panel
-Unorthodox SS Pulley Set (Crank, Alternator, Water)
-Unorthodox lightweight Camshaft Sprockets set at -5 In/Ex


Happy racing!

 

Just wondering..............did you have the car dyno tuned after all the mods or did you just put them on the car?

 

...In my zip code, the closest 4-wheel drive dyno available is probably 45-50 miles away. And, obviously, it is nothing similar to a Dyno Dynamics (which means that I would doubtedly use it for tuning).

All the parts were bolt-on (including Xede with plug&play harness), and they were installed sequentially in the following order and phases:

Phase I:

1. K&N Drop-in.
2. UR 3.0 Cat-back.
3. UR 2.5 Downpipe.

At this point, baseline G-Tech Pro Comp. measures were around 215-220.


Phase II:

4. Unorthodox SS Pulley Set.
5. Unorthodox lighweight Cam Sprockets.

At this point, G-Tech Pro Comp. was yielding 220-225 HPs.


Phase III:

6. Turbo Smart Boost Controller

At this poing, G-Tech Pro Comp. reported 250 HPs.


Phase IV:

7. Xede
8. UR HiFlo Cat

At this point, we saw the biggest jump in power, where the G-Tech reported 280 to 295 HPs.

I did heavily and methodically modified the Boost Map from the base Stage 1-93Oct map that Shiv published in Oct./Nov 2003.

That tuning was perfomed on the highway, with boost gage on hand, laptop on the right seat, and 25+ runs, until boost came out nearly perfect and consistent, regardless of how much throttle/RPMs/Gear I started off, all the way to 7000 in 2nd, 3rd and 4th gear.

Happy racing!

 

That's an awesome story, congrats on the gains
Do you use a wideband O2 sensor for tuning? What kind of data logging software are you using? My master plan is to get the G-Tech here soon, then get the pocketlogger and find some cheap wideband I can plug in, then start hacking with Xede and bolt-ons. Who knows how long that will all take to execute, but it's a plan anyway!

 

...And that's another key point: I *have not* tuned any Spark, Fuel or Knock maps from the Stage1-93Octane base maps that Shive posted. I only tuned the BOOST map, ensuring that boost went up to a max of 21-21.5 psi, being smoothly held to redline, with minimal decay (ends around 19-20 psi at 7000 rpm in 3rd-4th geear, thanks to the hybrid boost control setup). I did log boost on 3rd/4th/5th gear runs via XMap's built-in logging capabilities (quiet limited for what I was able to see).


I do have the PocketLogger as well, which I have only used to log some air temperature and timing readings, as well as reading and clearing a P0300 and P0420 codes that I got just after installing the hiFlo cat. Up to now, these cels have not appeared again. We will see.

Best luck and success on your upcoming project! Look forward to share more G-tech info. with you.
