How are they going to get 270/270?

HP gains?

This is exactly why I am waiting to see the Mopar staged upgrades. To me it still looks like the ecu is smarter than people are giving it credit for. Mod it to get more hp and the ecu detunes to maintain a set hp. I have no proof but am willing to wait untill the mopar upgrades come out to see what they do with the ecu reprograms.

w3rd! That ecu isn't f*cking around. The torque gains seem to come from exhaust. We've yet to see a dyno w/boost controller or without. I'm betting you won't see a 10hp/1psi gain like most cars will see. When the factory upgrades come out, or an aftermarket ecu upgrade, I bet we see dynos skyrocket.

Im with you on that one bro....and that has me keeping $$ in my pockets, but its just unreal to see that ATP only got about 15 horses with 16psi + their boltons, but the torque went insane.

This aint no regular ECU, this thing has AI!!!

you know what it is........dodge knows we want more hp, hp sells cars right? well if the computer wont allow you to get more hp, then you HAVE to buy the mopar computer upgrades if you want to see more hp. . :evil:

Also remember that the mopar stage 2 is not only a computer, but a new turbo, too, that will bump the horsepower.

all in all the computer 0wn3d ju guys! but i also think that lil 16g was designed to make the best use of the 2.4...Torque!...horses on 2.4s gather quickly when you mess with fuel and cams otherwise the computer and turbo have you all by the balz

Could it be injectors? Both MOPAR kits come with new injectors. I'm thinking the stock ones are maxxed out quickly. :?:

true too but also remember mr regulator IS gas tank mounted :roll:

Nah, doubt they'd do that for cost reasons. Im sure out injectors are good for their stage I and maybe II. It just doesnt make sendse to have 4 different injector packages for the car. They want to make money and the easierst way is to limit the injectors for each level.

If someone cracks the ECU, doomsday shall be upon Mopar :twisted:

i bet AFx ( www.howellautomotive.com )will be first!

I bet he's right too. They obviously have not added too many mods yet, not even a peep of what's to come. They're prolly hard at work cracking the ecu!

Stage I comes with injectors, doesn't it? However I do agree that the ECU is a large limit in stock form.

Gary Howell is a perfectionist and hes always got some stuff only he offers *cough* Indy *cough* WOW! could he making an Indy manifold for the SRT4 :roll: :twisted: :?

They say 30% injectors, but that doesnt mean its not a sw/ECU increase.

This is why I am jumping to the 40 percent version.

Even with the stage packaging, I noticed not much change on the piping or plumbing...why?

to what hemi?

I bet the injectors are included to flood the exhaust and turbo with fuel, to keep them from melting. I bet the stock injectors can handle that power, but it would start to run too lean to maintain the health of the turbo, exhaust and cat. Again, i'll wait to upgrade with mopar. Not that I doubt the aftermarket guys, bot PVO built the car, they know what needs to be upgraded.

Can someone please explain to me how the ECU "detunes" itself to maintain a certain HP? How does the ECU know how much torque its producing? That sounds like non-sense.

Horsepower is a function of torque. Its making tons of torque @ low RPM because thats right in the sweet spot of the turbo. The problem with making bigger power on the top end is directly proportional to how much the compressor will flow. Keep the stock ecu, slap on a larger turbo, add fuel... the horsepower on the top end will go up. I dont think there is any magical HP calculator in the ECU.

Math and computers are a neat thing. They have sensors for RPM, Mass Air Flow, Inlet temp, fuel flow, engine temp, etc..... There's no reason with that much data that you can't make a model and calculate the power. Besides, if the car controls the output, then the idiot who makes his own MBC and messes it up won't detonate his engine. Sounds like a safe way to control your 70,000mile warrenty on an overexcited sport coupe..
