Default ZZP no help...

Well, Zoomer helped me make my decision. After a few emails back and forth, Zoomer never once fully answered any of my questions regarding the reprogrammed PCM. Now I'm sorry, but when it comes to replacing a piece of equipment that pretty much completely controls the car, I would expect some pretty technical answers and Zoomer never once gave me that. I dont think I would be comfortable buying the PCM from him.. It'* just too bad C-ya is unavailable because those are the only 2 options it seems as far as reprogrammed PCM'*. So let me know when that Hypertech programmer is available. I am interested in getting it.

I called Hypertech myself yesterday and found out some info for everyone.

1) They have not released the PP3 for the 2000-2003 Bonneville or Grand Prix. You all know this.
2) They do NOT know when it will be released. They told me it could be this summer at the earliest.
3) The PP3 only changes the wide-open throttle program! It changes NO part-throttle settings at all.

Just letting you know. I might wait to see if Superchips comes out with a hand-held...

I called superchips this AM, Brian says "we're thinking about doing one for that car"...same sort of response I got from Hypertech.

The Josh, I am confused on the information you obtained about the Power Programmer. From what I know, if one became available it would have the same sort of functionality for our vehicles as it does with all other vehicles the PP supports:

Quote:
FEATURES
(depending on year, make, and model)
Hypertech Power Tuning:
Tunes the engine for maximum power and performance, plus potential gas mileage improvements.

Three Stage Power Tu ning:
Special Three Stage Tuning for 99-03 Ford Power Stroke 7.3L Vehicles.

Dual Fuel Tuning
Lets you choose tuning for 87 octane or 93 octane fuel

Engine Rev Limiter
Extends the engines RPM range for a wider power band

Cooling Fan On/Off Temperatures
Permits use of low-temperature thermostat for cooler, denser intake charge and lower engine operating temperature

Transmission Shift Points
Optimizes shift points by speed and RPM for maximum acceleration

Transmission Shift Firmness
Firmer full-throttle gear changes for faster acceleration

Top-Speed Limiter
Allows the vehicle'* top speed to be matched to the speed rating of factory approved high-performance tires

Speedometer/Odometer Correction
Automatically corrects speedometer and odometer readings with non-stock tire sizes and/or non-stock r ear-end gear ratios
(accurate odometer readings are required by law)

Turbo Boost Pressure Control
Adjust your boost pressure
I also found a table of features per vehicle (this one includes Grand Prix, Regal, Monte Carlo, Caprice, and Roadmaster.:

Quote:
IMPALA, MONTE CARLO, GRAND PRIX, REGAL, CAPRICE, ROADMASTER
Year Engine Trans Power Tuning Shift Pts. Shift Firm Top Speed Rev Limiter Tire/Gear Chg. Fans Part #
00-03 3.8 SFI Auto Dual Fuel Yes Yes Yes Yes Tire Only Yes 30014
00-03 3.8 */C Auto Premium Fuel Yes Yes Yes Yes Tire Only Yes 30014
1996 5.7 LT1 Auto Premium Fuel Yes Yes Yes Yes Yes Yes 30027
94-95 5.7 LT1 Auto Premium Fuel Yes Yes Yes Yes Yes Yes 30026
sorry its a mess, but you get the jist.

My bad. I was only referring to the calmap for acceleration, not the other features. Sorry. The other features are great. It will make firmer shifts and be able to change my fan-on temperature.

But, the performance program only modifies WOT settings of the 91 octane programming.

If you are not happy with Zoomer, why not try 3800 performance. I felt better going through them and had all my questiones answered. They also use DHP so there is more than one choice out there. I think the prices were the same between the two.

:P

I actually have been emailing back and forth directly with DHP. The tech there answered all of my questions perfectly and he told me that we can actually buy the pcm for our cars direct through them. They are doing this because it is still considered a semi-custom pcm. I am waiting to hear about lead time and will probably order it through them. Saves from any 3rd party hastle. But yeah, I am going to buy my pulley and stuff through 3800performace.

I just received a response on lead time. DHP said a pcm would be out the door within 2 days if ordered direct through them.

Couple questions:

What other mods would anyone suggest I do along with this pcm? I am going to be installing a 3.4" pulley and 180 stat. Anything else? I have read mixed reviews on adding a tranny cooler so I could use a bit of help... Also, what other mods would i need to do to possibly be able to go to an even smaller pulley? Thanks for the help guys.

We both have the same 2000 SSEi so you can see from my signature what I have done. I also spoke with DHP directly and they were VERY helpful and friendly The PCM changes the characteristics of the car so much, its like it can read you mind when to shift. It is well worth the money. GM sent these cars out with such a mild PCM program that its hard to understand why THEY wouldn't want the cars to perform this well from the start.

As far as the trans cooler, you can't do any harm having one it can only help. The police Impala'* are even getting them now, 03 and newer so GM must have realized they are necessary for the longevity of the trans. They also just started putting engine oil coolers on the Impalas for 03 and newer. These are the same motors and trans as ours just non */C.
