I met the craiziest FD driver in the world yesterday!!!!!

OK one of my friends owns an audio shop and I was dropping off a AST cuz he has a customer that cracked his and so I gave him my extra one.

This guy comes driving around the corner and his car sounds pretty beefy and loud. So i figure this guy is full exhaust, dp, mp WRONG!

This guy has DP, MP, Exhuast, RE Amemiya filter, Ported motor, 3mm seals, STOCK IC, STOCK ECU, STOCK Fuel pump, NO Boost controller, NO injector upgrade....NO upgraded engine management whatsoever!!!!!!!!!

This guy is one crazy *** ****! Plus he has 150K on the car....

R Xplicit

i used to be....."that guy"....but then i blew the everlivin' **** out of the motor.....i knew it was coming, but never faced the obvious....i hope this guy can get 'control' before he loses his motor.....

black99

Yeah not that hard to believe DP, MP, CB, Intake, on stock stuff, I had a 109k on mine and was running that. But 150k on ported motor? Or 150k on the car? Never heard of someone with that exact setup, damn that is a crazy ****..

RotaryKnight

150k on the whole car....he's had the built motor for awhile though......I can't imagine spending the money to build the motor and not have any type of fuel management. I've seen cars blow just on the DP, Filter and exhaust.

purepsi

since i live at 4200ft above sea level, here you can get away with dp,mp,cb,intake without upgrading the intercooler and ecu at 14-15psi but at sea level thats a different story.this is what i ran until i blew my motor

Maybe he actually knows what he's doing? There's no reason why a person can't run a full exhaust and intake and not blow his engine, it's just a matter of using pills or valves and keeping the boost at an acceptable level. IMO it's crazier to buy expensive upgrades like computers when it isn't even needed or provides no benefit.

Sure, you've seen cars blow with just a dp, intake, and exhaust, you've also seen totally stock cars blow up as well as cars with fully upgraded fuel systems and ECUs... I'm not sure why so many people think that plopping in a Power FC or some other tunable computer makes the car last any longer, it doesn't.

I ran a similar setup in my naive days....no probs at all with detonation.....my probs were all heat related.

Well IMO it's a better idea to not take any chances especially since if you plan on keeping the car awhile you are eventually going to need those upgrades, what's the harm in getting them before they are a requirement? Meeting the bare minimum is pretty retarded since you can save about 1000 and then have to pay out another few grand for a rebuild and then buy the computer anyway. Also a tunable computer will make your car last longer if it's tuned well.

RotaryKnight

Uh hello guys if you read the post he also has a ported motor!!!!!!!!!!!!!!!

mightyslash

****, I thought you meant he spent $150k on his car.

ThirdGenRX7

I think the proper word would have been retarded... not crazy

DELTA_Rotary

Your right... all of the RX7 tuners MUST be wrong suggesting upgraded fuel and ecu with those mods...owners like yourself are why RX7 get the reputation of being unreliable.

RotaryKnight

AHAH no kidding huh....notice the only people who seem to be agreeing with me are those who have been in rotaries for awhile.

Johnny

ahh...Wade probably know more then you do....about rotaries...

I agree it's not the smartest way to run a FD..but if boost is somehow kept in check 10-11lbs...why would you need the extra fuel. now if he had a aftermarket IC I might have some issues

RotaryKnight

he has no boost controller.........

Johnny

I know I read that part....change the size of the pills in the lines...can work you know...again I would not be brave enough to do it myself...but it is possible....not saying that this guy has done that...so I dont know...If not then yeah he's a little loco.

the key is he still has the shitty stock IC...this is really the key..upgrade that and his motor is toast.

If you are going to keep modifying the car and know you will eventually need a programmable, then sure, why not. But who's to say someone plans to do that, there are people who might want to open the exhaust and intake and never go much futher than that. In that case, there is no reason to spend $1000 (+ $$ for tuning) on a programmable if the stock ECU is sufficient. Not to mention the programmable might cause the A/C not to work or disable the knock sensor function.

Yes, a programmable that is tuned will will make your car last longer than a stock ECU that isn't. Likewise, a stock ECU that works great will cause the car to last longer than someone with a programmable that isn't tuned well... so?

My point is a car should be tuned well, rather than just having money thrown at it.

It just peeves me when people scream "buy this, buy that!" when it makes no sense. There are lots of people driving around with programmables that have no idea if their cars are tuned properly or not, and chances are they aren't!

There are people who know the stock ECU runs so rich that it can support just about all the mods you can throw at it as long as you don't raise the boost. And some people have found the Power FC base maps are too lean. Explain to me how putting an untuned programmable onto a car is a good thing.

They aren't necessary wrong, just misinformed...

And I don't do anything to contribute to the reputation of unreliability. I think that encouraging people to test and tune rather than just throw money at their cars is a good thing. It just makes RX-7's look worse when people blow motors after dumping thousands into "upgrades."

I nkow a guy running a ported motor and SINGLE TURBO on stock ECU and stock IC, and he runs over 10 psi, and he has run it up to 18 psi. He has also blown 3 motors though

ThirdGenRX7

It's not and that's my point. There is no way to be sure about a stock ecu with several mods, so what's the harm in getting a programmable and get it tuned to fit your car? That doesn't sound like throwing money senselessly at the car. And I haven't met anybody who has ever been able to stop modding their 7s, you might have, but i'm just saying that I haven't so odds are they will need a programmable eventually. You also have to admit that those mods without any sort of boost control is pushing the limits.

I shouldn't be dragging this on, but I don't have much to do at work right now, so...

There is a way to be sure with the stock ECU. The parameters of the stock ECU are not exactly a mystery, and the stock ECU can be dyno and lambda tested just like a programmable.

I have lambda tested several cars, some with lots of mods, and none have run lean with the stock ECU if the boost is kept down. Because of this, I would say that most cars with stock ECU's and stock boost should have plenty of fuel, and likely have acceptable timing. The most likely reason a certain FD wouldn't have enough fuel is if there were actually a problem with the car (like a clogged fuel pump, FPR hose popped off, etc.)

And I agree, spending money on a programmable and getting it tuned for your car is not throwing money away.

And yes, most people don't stop modding. I stopped power modding about 2 years ago and now I do mostly maintenance and reliability mods and testing. Testing costs a lot less than modding, it's fun, and it uncovers common misconceptions among forum/list wisdom.

RX7boy

bottom line is his motor has 150k on it and yours doesn't....I think this guy knows what he is doing....

RotaryKnight

He has 150k miles on the car but not the motor....it's like his 3rd so that says something too.
