trying to figure out what is the best fuel cut defender to go with or if anyone has suggestions and experiences?

the prev owner put a cheap one on the car just a nameless black box and has gone bad... need something nice

 

get an rtek www.digitaltuning.com much better than the cludge hack that is the fuel cut defender

 

will wait till when i get the money to upgrade extensively but im just wanting to drive my car till i port my wastegate and next spring im goin full standalone with an apexi power fc.. i may look into those a lot further though seems simple enough

 

Job #1 is to port the wastegate or restrict the exhaust to control boost creep.
All FCD's are just a voltage clamp so it just filters the pressure sensor signal just below the fuel cut reading (8.5 psi for example). They all do the same thing, even the DIY version. The problem with FCD's is that you are now running fuel and timing for 8.5 psi when you are actually running 10+ psi, which is easily achievable with an open exhaust.
I would recommend the Rtek 1.x upgrade, depending on your injectors. This will provide fuel and timing for the correct boost level. If you desire more fuel and timing control and have the cash, later you can upgrade to the version 2.1.

That's just my feeling on it. If you must have a FCD, Mazdatrix, RacingBeat and Knight Sport are some of the best known. You can find them in the classified section as well as new from their websites.

 

its all happening at once, just so its known im not fully ignorant. i have the racing beat revt2 exhaust and i wanted a max psi that it pushes boost creep to and then im porting wastegate. i know its risky but i wanna do it once so i can post it in the thread on here so everyoned else knows what can happen.

thank you guys

 

this isn't completely true. injector pulsewidth and ignition timing are primarily calculated by engine load as measured by rpm and AFM voltage. The pressure sensor does have some effect on it but it's not the same as on a speed density car like an FD, where the pressure sensor mainly determines fuel and timing.

 

Sounds like you want to blow your engine. If you boost creep up a lot; with stock injectors, you will blow your engine. It isn't hard to pull the turbo off and port it out. Takes maybe 2 days if you do it yourself. Save yourself a rebuild and port your wastegate.

 

if I had to choose, i'd rather hit fuel cut than overboost significantly. I've never had any problems from fuel cut but overboosting has severely detonated my motor.

 

im doing this to get an answer for people who have had the question about the racing beat exhaust, i know i may sound like an idiot but as i said im goin to do this once and watch my wideband so i dont kill it. i want an answer for ppl and then i will port. i havent driven my car since i have had the boost creep issue so i figure a motor with 35K roughly thats been babied shouldnt blow from a single instance of creep. this was not a question of insult and judge me i was just curious about fuel cut defenders and since i have a few specific ones to look at now thanks
