I was wonder if my stock system can handle 13 or so Psi setting.
My mod's are basic ~
STOCK ECU
Koyo radiator
3inch Dp
RB DT catback
HKS intakes
NGK plugs and wires
Knightsports FCD
Knightsports EBS III Boost controller
Walboro 255

Can I run 13psi without harm to the engine?

 

i wouldnt you cant adjust your fuel so you will run lean which as you no is a bad idea with these engines. Your gonna be running lean with you setup as is.

 

Well I was hoping the FCD would counter act that. The Knightsports FCD (Fuel cut defencer) It removes the top speed limiter and prevents it from running lean. Wouldn't it detect it and boost the fuel automatically.

"The FCDF is a fuel cut defencer and removes the speed limiter (180 km) for 3rd Generation RX-7's. An RX-7 owner using a stock ECU who has a few mods or planning to do so will find this useful. This unit will prevent your car from running lean (starving the engine of fuel), which can seriously damage the engine."

 

Should just purchase a new ecu they can be had for like $300 in the used stuff section pettit unlimited sounds up your alley.

 

I'd rather just buy a pfc there no point in buying stuff that has to go eventually... (I do plan on going single probably a to4Z or something along those lines...)

 

That will only prevent a lean out *AT* fuel cut (180km ish), by allowing you to go faster than that without hitting the fuel cut.
This does *NOT* boost your fuel in any way shape or form.

Get a new ECU or buy a lottery ticket

 

fcd is garbage.

 

amen!!!

 

Then PFC it is. Just as a question to all how much did you get your's for? The lowest I've seen new is 750 with commander an all.

 

You can do all the mods you want, throw in another engine too if you don't buy a new computer. Tune Tune Tune , that is why everyone blows their first fd up. I wouldn't go too far at all without a retune. Actually the first thing people should do is the computer. Power fc works great. You could turn it up to 15PSI safely then. ( as long as the restrictor pill is removed) I bought mine on ebay for 700, but that was awhile ago. Now I run Tech3R. $$$$$$$$$$$$$

 

huh, i thought i read somewhere that the FD didnt have a speed limiter... thought it was here....?

 

Some Euro models do, US models didn't.

 

ah k xD i was about to say, if hes talking limiter stuff at 110 mph then somethings wrong with mine cause ive been to 150 :P

 

I know, I was hoping to get rid of the 150 mph limiter

 

I own a J-Spec FD, and it has a speed limiter (180km/h) .

All Japanese cars have that speed-limiter...

"The FCDF is a fuel cut defender and removes the speed limiter (180 km) for 3rd Generation RX-7's"

Since it's made by knightsports, I assume it's made for the Japanese market, and they all have the speed limiter...
