Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hello all, Just picked up an '02 996 Turbo. Love the car so far and I'm excited to become an active member in this community. My 911 has a few aftermarket goodies on it I am finding. I got it from a local dealer so I have no way to contact the original owner(s) to ask about what they put into it. But, I am noticing that it is boosting at 1.1 bar, which I am finding is a typical boost level if the ECU were flashed. Is there any way to tell what flash it has? Here she is, in all her glory...

POST 2Original post

if you have not yet done so already, also try posting in the TURBO forum: https://rennlist.com/forums/996-turbo-forum-61/

POST 3 / ORIGINAL POSTEROriginal post

Oh woops, didn't even see that forum. I'll do that 😁

POST 5Original post

I'd like to know the answer as well. I think my car has a RoW ECU flash but I would to figure out how to know for sure.

POST 6Original post

IIRC, most of the aftermarket flashes for both Turbo and NA raises redline. If you can go past the stock redline without the soft rev limiter kicking in(Type1), there's a good chance that you have a flash.

I've never tried to go past 7000 yet. I'm pretty sure I have one. I can start the car without depressing the clutch (the clutch switch isn't bypassed) and I never ever get a CEL, and I hear the '99s commonly do for emissions crap.

POST 8 / ORIGINAL POSTEROriginal post

I haven't tried to go past 7k. I will try that tomorrow. I'd really like to figure out what flash it is. I'd like to know what I'm working with!

Pull up the carpeting behind the rear passenger seat and remove the ECU cover using 10mm socket. Some aftermarket tuners will slap their decal either on the ECU cover or inside it.

Good tip. I checked it out but alas, no sticker

Only other thing would be to strap it on the dyno since most FI tunes make noticeable power from stock which you'll definitely see.

A/F ratios get modified also which is anther way to tell if it's flashed...

True but it's a lot easier referencing power output than trying to find stock A/F graphs for a stock turbo.

POST 14 / ORIGINAL POSTEROriginal post

Sorry for the late update here. The car is definitely redlining at 7krpm and boost is consistently 1.1 - 1.2 bar. I'm going to take it to the dyno here soon just to see the power output, but I think it's safe to say that it's flashed. I'm going to try and find the previous owner. From what I understand the car has always been owned and serviced near me, so it shouldn't be too difficult.
