Question ProECM Powerchip

Does anyone have any experiance with the ProECM Powerchip or another chip on a stock 2.5 rs. Ive heard good things about chips in general but i was just wondering how the RS's take to them and what would be the best one to get.

superglue a plastic box to your ecu. flush $280 down the toilette. that's the experience you will feel.

Do a search on ProECM and you'll find more debates and "information" than you can ever hope to read in one sitting.

don't know why you would say this... I felt a definite change... and the biggest testaments are the people who have taken one off... they say you really notice it then... similar results with an AFC...

I like it, and will stand by the product...

Dolphin, if you really think that you're a schmuck. DrBoy is right, there has been much debate on how the chip works... I've gotten into a few "debates" with folks over the years and I can say this: I know more than I should about the chips function (I've been asked to keep quiet by the manufacturer) and I did use the chip before I went turbo. From my experience, Danzborin is correct, the biggest difference is when you remove the chip. The way the chip modifies fuel trim and timing is not an instant seat of the pants mod. The way the chip works requires some time for the ECU to adjust. Also, the more modified you are, the more beneficial the chip is. Bone stock and basic bolt ons are not getting the fullest effect of the chip. I can speak from experience as my RS dynoed the second highest stock compression hp/torque in Texas (that is to include when Cobb was headquartered here) and top 5 dynoed in the country at the time. The chip is NOT like a VW/Audi chip, the EJ251 is fairly aggressive in its timing already where the 1.8Ts and VR6s are grossly undertuned... no piggyback computer or chip as made more than 15 peak hp on an EJ251 (ProECM, Unichip, E-Manage, S-AFC/ITC combo, etc) except where the engines were VERY out of tune. Expect to see max 4-6 peak hp/tq on a stock motor, but the curves themselves will be drastically changed making more power across the powerband.

what about when the chip "funtions" for a year and then one day you start your car and it nearly explodes... black smoke, timing all eff'ed up, and just plain nasty noises. the Pro ECM chip is one of the biggest frauds in the history of the world.

If it works, there would be dyno results. The manufacturer won't even test it. It's garbage... and i fell for it.

I wouldnt buy this product unless I know how it works. It is very suspicious that they wont share how it is done. I know they say they dont want people copying thier design, but that is what a patent is for.

SO you're saying it works...but for whatever reason either the chip failed or you had another mechanical/electrical problem and now you're saying the chip doesn't work? Wow, not following that logic. Look, if you read the various threads Larry and David damn near give you the circuit diagram. What the ProECM does is rather simple, how it does it is pretty cool.

I gives me better throttle response, and better mid-range torque.
Maybe some people who buy it expect it to approach FI performance, and when it doesn't deliver that, they say it is a fraud.

If it DID approach FI performance, it would be an even better bargain than it already is at $249 or less.

Dolphin- what smoked? The chip or your motor?

There is a definite gain in power starting from 3500rpm. I had road dyno graph to prove it. I made 141whp with Ganzflow, Chip, flywheel and a catback.
The chip nature is to complement the mods you have.
Automatic RSes seem to lose the gain becouse of the drivetrain.

I stand by the product.

I don't understand why the ProECM wouldn't work with the AT. Even though there are more drivetrain losses, you'd figure a ~+5 HP gain would be enough to cause some change in the butt dyno.

However, I've talked to many 4EAT owners who have used a ProECM, and none of them seemed too enthusiastic about the product.

It is an issue with how it relates to the speed sensors in the automatic vs the 5 speed maybe? I don't know about that one.

However, ProECM does have a dyno graph out there on a stock RS with 4hp across the board, and you may not feel that. When I did the "5hp Stromung Catback" mod, I didn't feel a difference, but top speed climbed from 126mph to 132mph.

Boy and I know how the chip works, and we know it isn't fakie voodoo mumbo jumbo either.

I did a couple hard pulls in second gear tonight when it cooled down outside. It's still getting stronger...and louder.
