Stupid, stupid person. Sorry thats all I can really say after reading all that. Why did such an obviously uneducated person in RX-7's pick up such a fine machine running 435hp????

If you truely cannot budget for a programmable ecu then get a Pettit unlimited or M2 stage 3. Should be around 450-550, if you look around.
By the way, the car will run 'fine' for a period of time if the A/F is borderline, that's not unusual. The kind of power level you are speaking of CANNOT be achieved using stock twins (even running at 16 psi), I believe everyone on this forum will agree to that. Along the same line, the stock fuel system cannot support anything higher than ~350rwhp. The highest I have seen so far is 338rwhp with the stock injectors maxed out. So I don't believe you have the stock fuel system either. That being said, the reprogrammed ecu is designed to maximize the 'stock' system with all bolt-ons, ie. intake/dp/mp/cb/porting. Using them is not s long term solution and no one would recommend so. It will be better than nothing at this point.

 

Generally when it would start it would run nice and rich, I even tried to flood it because its more obvious of a flooded rotory than anything else and it just straight isnt getting the gas it needs to start, but randomly it will start, and it will give all the signs of running lean, and the idle has slowed from what it usually is...whats up with it ?

 

So an m2 would be enough to manage the fuel systemwith the power im running? Correct? Also "Steve" I could only imagine uneducated you were when you got your first 7, Ive been dealing with second gens my whole life, this is the first 3rd gen i have touched and personally id rather learn a little more about them before I drop 2g's on an unnecessary ECU...Steve please dont post any more replies

 

What's the use of giving you advice? All you want to do is contest our advice

 

Just as 93TTRX7 said, why do you ask our advice if you dont want to listen to any of it. get lost. Go blow your motor you UNEDUCATED SOB. I was educated when i got my first 7, thats why I did all the reliabilty mods the first few months and the car has been great to me with no problems!! Also where the hell are you looking at if you think you will have to spend 2g's on an ECU??? you can pick up the PFC w/ commander for around $1150 these days. Dont tell me not to post anymore, I say you dont post anymore with your stupidness!!

 

OK, first off, I see everyone here is quite passionate about the FD, and are not explaining in detail. No matter what Mods are done to the motor, if you start a huge single turbo FD on the stock ECU, it will run as it always has, because the fuel requirments at idle are not going to change, the fuel delivered is proportional to A/F mixture, and torque produced. The engine maked approx the same torque to idle no matter what the ultimate power of the engine is. Please no comments about PP, or BP we are talking a stock port, or nearly stock port engine. As everyone has said the stock ECU has fuel delivery tables programmed in to make a safe A/F ratio running stock power/air flow. Once you up the power which HAS TO increase the engine's air flow you throw the tables that are hard coded in the stock ECU out the window, the engine flows much more air than stock, with a corresponding leaning out of the A?F mixture. There are plenty of cases where people did DP, MP, catback, and intake and the resulting power increase made the tables lean enough to cause dreded detonation, and you know what that leads to. Now, I am not talking from a theory stand point, several years ago I did not know about this forum and the mod rules, and did exactly what I just described, and have the several thousand dollar bill to prove it. Apex seal broke both turbos killed by apex seal chunks, etc. No one here wants to see you break your FD. Take their advice, get some form of boost enrichment. If you cannot afford the Power FC, connect the waste gate DIRECTLY to the intake manifold, bypassing the control solenoid. That will limit your boost to approx 7 psi at least until you can afford a Power FC. That is the chaepest fix. Yes, it will limit your power, but you will not break your engine. Also you indicated a low Idle, and difficulty starting. Do tell once it does start how does it run??? Is it very shaky, almost like it has a miss. If it seems to Idle very poorly, and shakes I hate to be the bringer of bad news, but it may be too late. let us know what the deal is with the Idle. Good Luck.

Here's my solution...Sell the car to someone who can handle buying a $1000 ECU for it. You want 400+ HP but want to run the stock ECU? go for it...an Engine rebuild will cost you MORE than $1000.

Good luck

 

TwinTriangles, please explain the logic of asking advice, getting the same basic answer from several people and then refusing to accept it?
I hope you don't do this a lot or you will lead a very frustrating life.
Get an ECU designed to flow enough fuel or park it!
You are making the same mistakes many people did when these cars first came out.

 

thank u jspec, thank u grampa, and thank 93tt.the same exact thing i told him and he keeps denying it.and when his engine is blown like i said b4 and u all stated,we r gonna laugh cuz u were gonna wish u spent that 1000 dollars.and quit ignoring the question why did u take the power fc out in the first place???????????????????????????????

 

here check this if ur idle or turnover speed is slower.pull ur plugs and listen for ur compression it should sound even.like pop pop pop pop pop pop pop.if u here a skip or miss or it very slow this is a very good indication that ur 3 weeks of stock ecu running has just thrown a seal or made u loose compression.

 

 

If you where trying to flaunt your communication skills the lounge is someplace else.

 

Take these types of Comments to the HONDA forum please

 

That's harsh I didn't find it THAT offensive

 

It wasn't offensive Gramps...it was Childish...Hence the Honda forum...

 

With that rule set the majority of those in the kills and lounge are on the wrong forum.

 

Get a used pettit UNLIMITED ecu, you'll be able to run your current fuel systems upgrades, etc. A M2 stage 3 probably wouldn't work well for you.

 

i no longer know whether this is an actual thread or just someones joke

but either way please list ALL of the mods that have been done to your car twintriangles... atleast all the ones that u can see or know about. if you cant do that much then you have no business owning a 3rd gen

oh and like trex stated, it is impossible to make 435rwhp on the stock twins. r u sure that your information is correct ... please post your dyno run

you would have to be running M2's BB twins at about 20psi to get a number close to 435

LIST ALL UR MODS

 

Darwin is calling...

https://www.rx7club.com/forum/showth...threadid=95424

 

I'm thinking he got the numbers mixed up...345 perhaps...or even 354 is still believeable

 

i swear this guy is really beginning to **** me off

 

Have you done a compression test? This will tell a lot. Instead of arguing about which ECU to get for a good price, make sure the engine is still fine.

 

The engine is all good, did a compression test and it came out perfectly, this engine only has 2,000 on it, the guys who tuned this said that the stock ecu should be ok to use, that is why I question all you short fused ********, because I would rather not spend allot of money if I DONT HAVE TO, that is also why I would rather get advice from multiple people and not just take the first offer on the table, For the rest of you who havent been cool about it, I think your just pissed because my car would blow the doors off anything you got.... thanks for your time anyways and the little help that I have recieved from this forum full of **** sticks and ********...

 

Then leave the forum dipshit. You did get advice from MULTIPLE people and they ALL SAY YOU NEED A DIFFERENT ECU. Sell the car and get a Honda, they dont need much attention to detail. As far as blowing the doors off anything we might have, well guess what, what we have are CARS THAT ACTUALLY RUN RIGHT!!! You car wont even start, kinda hard to blow the doors off anything like that now isnt it mouth.
