ok guys going f/i with trd s/c my questions are about ecu

should i go trd reflash and then piggyback it?
or
should i just scrap trd reflash and go with AEM f/ic only?

is it safe to go just with the AEM? or should i reflash it first and then piggyback it ? thanks

 

im thinking you need the reflash any way because the aem fic is infact still just a piggy back. i think it would be different if you got a stand alone?... I could be wrong though.

 

yea i would go standalone but its mucho $ so i wanna see if i can use just the f/ic bump

 

don't buy the s/c cuz it sucks, spend the money on hookers and drugs instead!!!!

kidding, go standalone

 

as I said mucho $ so planning on going piggyback

 

umm people have chimed in for you on that one already..in your previous thread.

yea I saw that lol umm I actually see that you mentioned something about doing a lot of tuning I talked to my installer nd he's actually an AEM dealer so yea nd when I mentioned that I was gonna get the f/ic he was like "now were talking" lol 05 rs1 do you think ill b ok with just the f/ic?

 

^ Yes... As stated in the previous thread, That is what I'm planning on doing too. The F/IC has alot better features than the e-manage, as shown by Paul at Dezod. It's just a matter of your tuner knowing how to tune it.

 

so I take it that you r going with the just the f/ic? that's what I think I'm going to do to instead of the trd reflash so I hope everything will be safe (crosses fingers) if anyone else has any info on what I should do please let me know

 

No, what I'm gonna do is get the reflash done first. The dealer is going to do my install, so they are gonna do that too. Then, after a while of driving my car, I will get the F/IC for the upgrades I'm planning on getting. (9.5lb pulley, CAI, and water/meth) The F/IC is just a piggyback.

 

o ok gotcha yea my s/c is used so really cant have them install it i can but they won't warranty it so that is why i am having my friend do it for me

 

if you want the reflash as a starting point (which i think alot of people would recommend) this guy is selling his.

Go to page 2...

 

like i said, i would get the reflash and then go from there. it's a good starting point and at least your car will be able to run ok without a tune for awhile (as long as you dont go WOT)

 

yea there is no way I am runnin my normally n/a car with f/I without a tune I know it can for a while but no point in risking it my installer is just going to do everything at once install it and tune it...
I spoke to him and he said the f/ic works real well with the scions plus If you think about it is like if you just had an n/a car and went turbo its almost the same concept u can run a piggyback and still be ok just as long as there is something monitoring the f/i

 

Scrap the supercharger and go turbo.

 

^^^yea no...do you wanna pay for me to go turbo? b/c if your funding it be my guest i would love to just dont have the $

 

I'd have to disagree with that...
...with a turbo, your car is running almost exactly the same until you get into boost, which is up around 3k rpm, and only if you mash on it. if you accelerate slowly, you can get up to 4krpm and never kit boost. So as long as you stay out of boost, the stock ECU is fine, caues it's not doign anyting differnt.

The SC gets you into boost and increases power throught the entire RPM range, so your AFRs will be elevated ALL THE TIME without the reflash. This also means that you would have to tune the F/IC for the ENTIRE RPM range instead of just clamping down the MAF and tuning the boost portions.

Yes, you have to map everything for turbo as well to compensate for the larger injectors, but not as much as you would have to for the SC. I would DEFFENATELY recomend starting with the TRD reflash and then going with the F/IC later on.

Or a standalone!

 

screw the reflash, just tune the stock ecu with the f/ic.

 

I know it sounds so easy doesn't it lol if you can give me some insight and some piece of mind that I would b safe without the reflash and just an f/ic tune

 

why wouldn't it be safe, when you install a turbo, you just use ems to tune the ecu, you dont reflash it first. I wouldn't drive the car on the street for a long period of time, but installing the sc then driving it to your shop, to get it tuned, shouldn't be a problem.
