I purchased the ECU 93/93 high altitude flip chip from Jeff, also picked up the drive by wire..

Anyway, took the Bosch ECU out of the car, took the wiring harness and stripped all the italian electric tape, better known here as friction tape, installed the FD wiring harness, about three hours as I didn't see the Bosch unit for about 30 minutes, was digging around behind the kick plate and then finally looked up, hello! There is no room to work on this in the car, if you are a decent sized person, you will need midget arms, it took me a couple of times and some patience to make all of the connections.. I even re-wrapped the wires in friction tape like the factory, but I also put a couple of stitches of electrical tape on first to keep the wires together, then the friction tape on top of that...

Anyway, I went out for a spin, the DBW reminds me of my 68 Camaro SS with the 3200 rpm stall convertor, the acceleration is instantaneous even here in Denver at 5400 feet on the north side of town. Anyway, after about 4 or 5 minutes my car started acting goofy, so I call up Jeff, he's out at Pocano, and he asks me some diagnostic questions, I give him the answer, then he says I need to check the pins in the 8 pin connector on the DBW as they must not be tight. Anyway, I do that and ta da!!!

Anyway, I then plugin the new ECU, the car was much quicker with just the DBW, but with the ECU the rush of power comes in harder than ever from 3800 rpm to 7500rpm and I mean hard! According to the previous owner my ECU has already been re-flashed by another vendor, but adding Jeff's ECU chip to the mix makes the car much peppier!

So my 0 - 60 time from a dead stop went from approximately 4.9/5.0 seconds, I am at altitude, to 4.6/4.7 seconds with just the DBW.. That's with traction control on and it was 92 degrees outside. Anyway, with the new ECU I am almost always at 4.6 seconds... I was running a full tank of fuel, not sure how much the car holds but it's 6.5 pounds per gallon so after 10 or more gallons is gone, it should be a smidgen quicker.. Also I notice that the whole feeling of the car is much more stable, a lot of powerful and no longer a clunky embarassment off the line.. It feels like a real automatic, just like Ali described, the power is immediate, the pull is amazing and the rush of power is more because of the ECU... I feel like I am driving a new car!!!!

One of my SRT-4 Turbo buddies can't get the hole shot anymore and I have more pull now even though he is running his 14+ pounds of boost... I am super happy at the moment with this. I still need to finishing mounting the DBW box and the ECU box behind the kick plate and if anyone here has any good ideas where I should, please respond to my post...

Ali, where did you mount yours??

Thanks for the great review, the DBW is on my short list of things to do. I was still sitting on the fence, but you just made my decision a little easier.

I mounted the DBW directly on top of the factory module under the kick plate with velcro. Then bought a new toggle switch from pepboys with a carbonfiber flip lid ($8), drilled a hole thru the leather directly under and to the right of the steering wheel, mounted it - the 2 wires went right thru the center console with a wire hanger. Now I can flip b/t the modes on the fly.

Sounds great! I bought the DBW and springs from Jeff, am having the springs put on end of this week and just need to find time to add the DBW - or may just let the shop do it. Can't wait to get rid of that hesitation-then-lunge when you hit the pedal hard.

Ramp!

thanks!!! I am off to get some velcro!!! The ECU I can stash pretty easily, it's the DBW that's a little thicker...

Check with Jeff but I do not believe it is adviseable to flip programs with the key on or car running. Jeff can clarify, hope I am not mistaken. I have installed alot of his products and have always advised to shut car off prior to switching programs.

Glad to hear you are happy with the product.

all the best,

Mark

I switch the DBW program on the fly all the time with no issues

Yes, it's safe to switch the DBW on the fly but the ECM needs to have the ignition off.

Best Regards,

Does anyone with the DBW actually ever use the lesser aggressive mode? I've kept it on the more aggressive mode from day-1 and never used anything else.

Vincenzo,

I am the same way-- never used the less aggressive mode!
I do switch it - the problem is I'm not sure there's any real difference -it's barely perceptible.
