there must be something on here in the past but I could not find it but what I want to ask is what is everyone's input on this if I just going to run full ext, intank and maybe a vmont IC later on o ya and a fuel pump.Well the thing with me car is that I'm getting marry next year and well my gf soon to be wife i hope has me tight when it comes to putting money into my FD for MOD's so everything I do to it I have to save on the side or make sure its not to much bcuz where buying a house and other things so with this out there , I just want to know if I just get a ecu like a M2 or something like that will I be ok runing it here in socal with 91gas or will I be pushing my luck or should I just do the power fc that I know works great but meen I need to buy it $700-1,000 + 2 fuel injeters 880cc to 1300cc done by RC for $150 each + like $400 to put them in + $250 for the fuel pump + $600 for a great dyno tu from rr. I would like to know everyones input knowing what I have to deal with o ya and if anyone has run one rx7sote power fc tune with 91gas.
Hope to get some feed back that will help me pick thanks

 

ok well .. the stock tune on the power FC , if you Read some of Arghx threads , about safely tuning using hte commander on its own . will be enough for the mods you have , you dont even have to upgrade the injectors , or the fuel pump, or the dyno tune .

unless you plan to run some crazy high PSI number . ( over 14 ) . the car's stock fuel system can take up to 14 PSI of boost . but to be safe ( I've been told its better to run it at like 12)

all of that on the stock fuel system . with a stock power FC tune , which idles better, and does everything better then a pre tuned ECU . plus you get a built in boost controller , and all sorts of things with the power FC and commander , also being able to moniter some extra things using the power FC , and record for knock and stuff is truly priceless when it comes to saving your car. every car is different and unique and thus requires a tune to go with it . you can tweak the power FC to make it perfect , or use the stock map . and leave it stock ..

BUT one thing you SHOULD DO if you eliminate the CAT , is port your waste gate . regardless of what ECU you go with

 

If you are planning on upgrading down the road then go with the Power FC. Dont waste the money on the M2 ECU which has no programability. You dont need to upgrade your injectors right now.

Good advice all.

OP, for the love of God please incorporate some sort of punctuation in your posts. Thanks.

And yes, a PFC is also my recommendation. There are good deals in the "Parts" section.

 

You're telling stories.. I can reprogram the stock ecu - have been for the past year(s).
injectors, fuel map, ign map, etc. all ya need is a ton of time to figure out hte pos MCU it runs, write a disassembler for it... etc etc :-)

Point is, it's actually re-programmable. I had a small project where it read from an external NVROM and was able to flash on the fly but its pretty slow in that respect and found it worth while to buy an AEM and forsake the ecu project.

 

If a guy like yourself gives up on it, then it can't be done.

 

Punctuation would be nice,

 

Thx everyone for your feed back it helps allot so if I was to buy a power fc and just run the tune it comes with how safe would that be running it here in socal with 91 and not 98 that you get in japan? Sorry for asking so manything

 

For the average joe its not worth it, but I know what you mean.

 

If you are going to run a full exhaust then you will need the program adjusted a little, especially since you are running 91 octane.

 

Ok this is the plan I have came up with for my car, I'm going to run the M2 ecu for now I got a good deal on one , so this way I can have fun with the car now and work on the other thing's it need's and then later on when I'm done with all of the thng's it needs I can do the power Fc right with 1,300 cc and a vmont and a very good dyno on it so I can hit that 320 whp I have been told it can do with those mods and oem trubos , and maybe then I can find someone that in the same boat as me right now and buys the M2 ecu off of me if not I guess I can keep it just in case I need it

but I want to thank all of you guys for your input , it help allot and I will do my best to help others with anything I can

No but seriously, I think you'll find that you get the best use of this forum when you ask clear and concise questions.

 

ok thanks

 

It wasn't even worth it for me to do it.. I did build a startup cal for another ECU from all the crap I learned (oem calibration wise). I dont think the price / time was worth it though. You're 100% right! :-)
