Default new car, how long should I wait before getting reflased ?

Hi,
I just got my 04 wrx couple hours ago, I'll looking to get the AccessECU stage 1.

How long should I wait before sending my ECU ? I'll go easy on the break-in period. Hopefully, I'll finish it early next.

Thanks

Sam

I'd wait until you hit the 3k - 4k mark......I have no proof as to why I'd wait this long - it just makes sense to let things settle in a little before increasing power.

Lightbulb ...

We recommend between 2000 and 3000 miles. Subaru engines are built with extremely tight tolerances from the factory and putting too much heat into them early will cause problems.

Treat the car nice now and it will pay off in the end!

Is it impossible for a driver using the stock ECU flash from FHI to drive in such a manner that he is "putting too much heat" into his engine during the first 3K miles? If not, why haven't you guys developed a "engine longevity break in" flash that prevents the "operator" from inadvertantly "putting too much heat" into his engine? Advertise it as such and promise a free "performance upgrade" flash after the engine has 3K miles under its belt.

A true "stage 0" on the Cobb Tuning path to power.

It's extremely possible to abuse your car during break-in with the stock ECU. The more agressive map really just encourages the early abuse. As for a "break-in" map... People complain enough as it is with having the car out of commision for one day..

Power is addictive and I was merely stealing a page from the Alcohol & Tobacco marketing handbook: The earlier you get 'em hooked on your brand, the greater the chance you'll have a "lifetime" (however brief) customer.

But seriously, a Stage 0 "break in" tune might form the basis on which Cobb could offer some kind of warranty, which would certainly distinguish Cobb from other WRX tuners in the US. Cobb would receive the new car's ECU along with a copy of the sales papers (to insure it's new) within a certain time period of its sale and the Cobb "stage 0" tune would insure that the owner has little chance of abusing his engine during the break in. True, few people would or could avail themselves of this option, which is part of its beauty: being able to advertise oneself as the only tuner with a warranty and having very little actual risk. I shoulda been in marketing.

First 3k miles from what?

Does the ECU have its own built-in odometer that is immune from resets? If so, how would it know how many miles were on the car as opposed to the ECU?

Does the ECU look at the car's odometer?

If the ECU has an internal odometer that can be reset, do you have to sit through 3,000 miles of "break-in" every time you do a reset?

Unfortunately, the WRX's ECU (unlike others) does not maintain an engine hours or mega-revolutions counter.

NO... the ecu doesn't know or care about the number of miles on the car. It's 100% up to the driver to break-in the car properly.

Why wait for 3-5K??? The recommeneded break-in period is 1k, other than #3 cylinder toasting with mods, the motor should be through all of it's heat cycles by the 1k mark.

Why do you think there's a problem with #3? Far more folks here have lost compression in #2 or #4 than have had problems with #3.

Default #3 CEL

I have had a CEL come on numerous times and the dealer said it that the code was a misfire in cylinder #3, but that if I didn't feel anything that it was just the ECU being oversensitive. Is the dealer pulling the wool over my eyes? Is there a known problem with the #3 cylinder?

Thanks

You guys are funny. Talk to someone at one of Subaru's manufacturing plant but chances are every engine that comes off the assembly line is redlined before you buy. Most like without beeing warmed up properly first.

Also the reason Cylinder 3 is such a prevelent problem is because the stock turbo location is right next to it. Can anyone say heat soak

I hope you are kidding. #3 is the one that likes to die. If you aren't modded, take it back and complain. You could do a compression test to verify for sure. I have my EGT probe tapped on #3 for this very fear.
