I have a guy out here in AZ that says he can re do the stock computer in my Gen 2 and it will be a noticable seat of the pants difference, but I'm a little skeptical of this.
What do you guys think of him taking the computer out of the car and re flashing it with some program for $600 bucks?
BS or no BS???
From what I've seen on dozens of N/A cars with a computer re flash is maybe 10 to 15 RWHP difference. I'm thinking the same results are probable with the Gen 2 as well, no?

lol, well, he is likely just going to send it to DC Performance and pocket the difference.

If it was an SCTFlash tool & tune for 600, then JUMP on it. This would however not require removing your computer.. so I doubt thats what he is talking about.

If I knew more about your car, I could tell you more. We are authorized SCTFlash Dealers & DCX Tuners here.

Thats about what the results will yield. Had it done to my 98 recently. You will not not notice 10-15 RWHP. Better to save the money and put in 3.55 gears.
PM me for more info.

Right now the way the car sits it has the 3:55 gears, short throw shifter, Fidanza flywheel, smooth tubes with K&N's, Belanger headers, no cats, and 3" Corsa exhaust.
I dynoed it on a DynoJet on Friday prior to installing the Lightweight flywheel and it made approx 452 RWHP and 486 RWTQ

The guy working the dyno said that I was running way too lean at over 13 A/F
I'm sure that isn't a good thing, although one of the guys on the Alley told me that it could be just that particular dyno not getting accurate readings by shoving a hose in the tail pipe.:confused:

That looks a tad lean, even for a tailpipe wideband. I always recommend putting in a wideband before the cats, its the only way to know what you are REALLY looking at for certain.

You car is certainly a candidate for the SCT-Flash. We have them at 574.95 for (1) tune. The advantage to the SCT over a "PCM removal" reflash is that there is no downtime, and no disassembly of the car, and its cheaper in the long run if you change the tune more than once while you have the car. The full reflash requires removing the PCM, sending it in, and paying the full fee each time.

With the SCT on the other hand, you purchase the flash-tool and tunes, and then the tunes can be loaded and stored at will into the flash tool independantly of the PCM. The flash tool then flashes the PCM with whatever tune it has stored that you would like loaded, and can be returned to stock at any time. You can still drive the car while the flash tool is in transit back and forth to us, and additional tunes can be written for 75 each in the future.

Hopefully before summer, the tunes will be E-mailable, as well as the flash tool doubling as a logging device- then you REALLY get your monies worth! (dont delay! all current tools will be upgraded for FREE when these features are added!)

Sounds like a Diablo programmer.
Ron Zimmerman is the guy that I would be sending the computer to if I went for the one shot deal route.
He is supposedly the guy that writes all the programs for GM and Mopar.

1. Similar to a Diablo, but it does not operate quite the same way.

2. That would be your choice, can certainly go that route.

Your deal sounds interesting because it can be adjusted if and when I make any changes to the car.
So what are the real world HP & TQ #'s I will end up seeing when I take this back to the dyno with your program added? I know it just a guestimate, but what is the least amount I would see and the best?

15 rwhp is pretty commonplace on the top end, and larger gains are seen in the mid-range. Larger gains can be seen on cars that have 708 cams or are modified, especially those with even bigger cams and portwork. However, this is not just an AFR tuning system- it can change EVERYTHING, many of which most would place at the same level of importance as the AFR itself. In addition to AFR and Spark, you can change Fan temps, idle, closed loop maps, injector scaling, OBD-2 monitors, various hardware and diagnostics, etc... the list goes on. Have a question about something that bugs you about your car? Ask! We might be able to simply turn whatever it is off in the programming.

Special considerations also need to be given to Paxton blower cars or TT cars, (we use a REALLY trick type of fan cycling on them), and SC/TT SRT's eliminating the WOT timers that slowly destroy engines if left enabled, or kill throttle response on the NA cars.

We have also seen excellent results when combining the SCTFlash and the VEC-2/3 for big power SC and TT cars. The systems work extremely well together, and when paired can handle any engine combination out there flawlessely. You can move most of the VEC's duties into the OEM PCM, and the VEC only has to work in a single dimension of tuning speeding up its processing, while everything else but boost is handled at the base level. The VEC's downfalls are its inability to scale very large injectors, controlling closed loop effectively, and its "shady" nature in vacuum boost transistions because of wandering closed loop trims.
