Wanted to wait a little bit to get some seat time with the RaceChip Ultimate Installed. Installation was very simple. Connections were very nice as well. I really enjoy the adjust ability that the racechip has. There are 2 switches S2 on the left S1 on the right. I've been told the S1 knob must stay on "1" the S2 knob/switch can be adjusted. It was Shipped to me on stock setting of 2. The max being 7. From the first drive the car felt like it was tuned. Great response from the pedal and felt a bit quicker. Raced a couple cars from both a stop and from a roll and worked great. the Max I got the switch to was about 5. It was the first day the track was open so I figured I could get a coupe runs in to see the results of both the RaceChip unit and the RamAir setup. Ive had the RamAir setup on for a little bit and know its helping a ton from a roll just wanted to see how much. I only got one run in because lanes were ridiculously packed. I posted results in Dragtimes and I believe it set a "record" for Quickest/fastest STOCK ECU. I am very happy with the results. The RaceChip box was set on its factory setting for this run. I know the car would have made a 10 sec pass on 5. It also seemed to launch a ton easier so thinking the 60' could be improved as well.

Mods are
K&N filters with baffles cut out of stock boxes
Exhaust shop cut off cats and resonator stock piping and mufflers
Racechip Ultimate on stock setting.
Custom Ramair
93 Octane Shell gas

Here is time slip and video

Wow those numbers are amazing. Thats actually stronger than some full proper ECU tunes some people have posted. How is it possible?

Did you dyno the car? Im curious what kind of power its making, good job!

And what is this custom ram air you speak of?


Nice runs - this is a piggyback module, no?

piggyback yes.. $598 ...

Yes Piggy back. Plugs into rear larger connector, Map sensor and also cam sensor.

I'll Dyno Someday but numbers are all over the place these days I'd rather have track results. Dyno numbers dont win races!!! hahah

Can you take some pics of how it plugs in? I want to order it, but also want to see how it installs. AMAZING!!

These are the ramair inserts I'm talking about. These were for fitting and then I made some from thin metal. IAT's dropped a good amount at highway speeds and seems to pull a ton harder from about 60. Going to try and get some 60-120 times. Is there any decent apps for iphone that will do 60-120?

Comes with Detailed Instructions as well. Attached

So whats the point in doing an ECU tune if we have this MUCH cheaper option?

Thanks for this. The pictures help. How long did it take you to install?

im thinking the same thing...........

I'm lost on your ram air scoops since it looks like they're just directing air over the motor. Can you fill me in on what I'm missing?

hahaha yes they go behind the grille. Thats what the second picture shows

Probably not melting your pistons... just check the disclosure page on their website...LOL
I could summarize it in a sentence: "we wash our hands" and if you buy our "warranty" good luck getting a claim honored.


Good numbers though, and I am glad that I do not buy used cars...

Lol, I thought they were mounted.

I still don't get the ramair sections how are they guiding air into the intake?

I'll take some better pictures. You would understand if you looked how the air ducts get the air to them unless e63s are much different from my cls

I was under the belief that ram air or positive pressure on the intake side didn't help turbos as their boost is not (or less) dependent on intake pressure.

RAM air turbos do help.
I picked up 4mph in the 1/4 mile by doing NOTHING more than blocking off the grille and only allowing the air to pass through the turbo

LOL well that sums it up, better not to cut corners.

Weren't these already reaching out to fresh air at the grille?

Melted pistons can happen with tuning the ecu directly as well, don't be fooled. In fact most piggybacks tend to send the car into limp mode well before you go out of hand with changing parameters.
I have tuned several types of piggbacks and standalones in my time, its more about the tuner than the device used especially when you are NOT changing any factory hardware (downpipes, intakes do not count, they barely do anything the stock ecu cannot handle on its own)

I'd question that being a ram air effect, especially since you didn't change anything directly relating to funneling and compressing air in front of the turbo. I'm not saying either one of us is right or wrong but I'd postulate there's more aerodynamics involved in your changes than ram air.

Btw, love your car! I had two gen 2 Camaros myself.

I like it! This looks really easy! Where and what do the adjustment dials look like? or is it just controlled through the phone? Can't wait to see what setting 7 does!
