Tune it. Boost without management = Fail.

I ran 6psi with a T3/T04B for 3 months and 7psi with a T3/T04E for another 3 months before getting a FIC. That was around 6,000 miles w/o management and I've now gone another 14,000 miles boosted without issue. That was stock ECU with 440cc injectors, a SMIC and 93 pump.

I'm not recommending what I did for the long-term but the base map you can easily build with the FIC software is more than safe enough to get you to a tuner.

I consider that a tune. That may not be the best way to do it but you have something. I am referring to people that run completely factory ECU and no injectors or just factory ECU with only injectors. Try running that way long term = fail. Measure your EGT's without having management and see the difference on a stock tC and your boosted without management.

Sorry guys off topic but:

I bought a $hitty ebay kit like a retard cause i got impatient on saving with a slow job. however...

I am running 6psi on stock injectors and i have my AEM FIC and dont really know my way round the software too well. But I know enough to follow directions if i had some, as in if its running lean in what cells under the fuel map do I change and what do i put in them to make it run around an AFR of 12-13?

Those kinds of questions I have.

My 440s are practically maxed out at 6psi (90%IDC). You would have been better off investing in larger injectors than a FIC. Now that you have the FIC you can go with 550cc or larger and IMO you should do that very soon. I hope you at least have a AFR gauge...

haha wow what a good parent. At least that will keep her safe lol.

Another question: When I am in the screen to change the AFR, what else do I need to change and how do I change it to match the AFR i set it at?

Dumb question I know sorry. And I know ignition is the answer or one of the answers but how do I do that and what do i change it to?

TUNE IT!! I know how hard it is to stay out of boost when its there, I went about 2 months with no tune running 7psi and 550cc i drove it to work a couple of times witch required going up a big hill (grapevine,CA.) no matter what i did it would go on boost, fr's would hit 10 on my a/f gauge, anyways the problem was after it was tuned and i was driving it hard than it caught up to me and the engine took a dump about 3 months later, It only had 20k miles on it.... BIG MISTAKE.. My recomendation: TUNE! Save ur self another nightmare like ur other car.

I've always wanted to install a car battery or multiple powerwheels batteries wired to up the voltage on those things just to see what would happen....maybe on a toggle switch hooked up to a relay? Might be fun. Not that I would recommend that for a kid... but were all kids inside...

Wait, you had a wide band when you had the turbo kit on the car? why didnt you run it to see what it was doing. That would have told you right then if the tune you had was safe.

No offense meant but I find it very hard to believe that a little part-throttle boost going up a hill with open loop AFR of 10:1 did any damage to your engine. It sounds more like the excuse a tuner might use to explain why your engine blew while running hard on his tune 3 months later.

X3. If anything all you would need to do is change your oil, plugs, and you should be back to normal. You would only have to do this if you were running that rich for a period of time.
