Revo stage 3 + Revo SPS + Stock turbo, small Q.

**starfriend** · 04-23-2008 12:32 AM

Hi,

If my ECU is flashed with the Revo Stage 3.

Will i still be able to put the car in stock mode with the SPS, and use my car "as stock", with all stock parts (k03, exhaust, intake etc.) ? Its basicly a downgrade to original flash?

The reason im asking is that i am waiting for my kit to arrive, but i want to go and get my clutch in before i install the kit. And that would require the ECU to be put back in ;-) but when it comes back, it has the stage 3 flash.

Thanks guys!!

um no, dont flash it till your kit is put in

You could in theory but your car will run really shitty -

I guess you could trim it all down with lemmiwinks - but just fair warning

if you are asking this question, you shouldnt be installing stage 3 hardware or software. just my opinion.

thats a rather stupid post denver, that i could be without. This is a question regarding the SPS switch, and has imo nothing to do with the installation itself.

To you other guys, thanks.. can anyone please confirm this? :-)
Whats the SPS definition of STOCK? as mention in the product description?

thanks guys :-)

If you have the larger injectors in with the new software, yes (stay out of boost). If not, no ...

it's not a stupid post. if we're considering what he said stupid -- you dont even want to hear opinions on YOUR post.

point he was making is that having a stage 3 car can be very involved... and you're going to need to know how to care for and work on your car incase anything should go wrong. asking if you can run a tune for a totally different setup on your stock stuff just plain doesn't make sense. The answer is NO don't do it. Stock means stock boost levels, but a larger turbo still flows more air at stock boost, and the injectors would flow more fuel accordingly... you're risking some serious damage or weakening of your motor right before putting in the big toys. not something i'd do. like shawn said - you could get away with it if you have the injectors in... but your car is gonna run like crap. (way too rich)

and fyi - you should just wait to put the clutch in. put in your turbo kit, put the ECU back in, and THEN go get your clutch done. Lee has an apr3+ on the stock clutch and he does fine. (granted he drives like, 5k miles a year) point is you're ok for one trip to the shop.

not to mention you're gonna have to wait to really hammer on your new setup now anyways while that clutch breaks in. no point in rushing and risking harm to your motor. just be patient, do it right, and do it once.

it was not in the least a stupid post...if you have not done enough research to know what differentiates a stock file, a BT "stock emulating" file, and the other assorted oct. specific files, how then am i to assume you have the accumulated knowledge necessary to even know what you are putting in your car, much less how to use an SPS 3 or any other device/software manupulation like in lemmi.

in a nutshell, there is no way in hell your car will run correctly with all of the tweaks or otherwise necessary to even try and get your fuel in line...forget boost, timing, and other VERY important factors involved here. there is a very good chance that running a 440cc file on stock injectors that you will run drastically lean based on the ECU's load calculation...i dont believe even with all the lemi in the world you could get that to balance out...there just isnt enough room in the ECU.

those are my thoughts as to why...if you want me to go into further detail as to how the fueling system of this car works...id be happy to...im dreadfully familiar with it.

p.s. running lean is bad.

on a side note...the OP has really sparked an interesting debate here...im not as familiar with the BT REVO software....anyone out there know if REVO BT software ignores the MAF signal. Im not trying to strike a debate...but the way the ECU reads signals will be drastically effected by that answer in and of itself in this very specific circumstance...

fueling could be dramtically influeneced given stock injectors and a file written for larger injectors outside of tweakable range...especially if the MAF signal is ignored...the MAF signal when operable is critical to fueling...of course there are also many ways to tune with it disabled...but the ECU wont be as flexible in that state and could exacerbate this problem further....just curious on that note.

please, dont get me wrong cause of my bad english.

I know that a BT file uses relies on bigger injectors, more air and thus expecting a complete different setup.

The thing is, when i started reading the description it stated that boost, timing can be adjusted induvidualy with this switch, and there is a mode for "stock" on the stick. Which made me to believe that maybe revo had both files on the SPS, or saved in the ECU.. and with the stock mode you could switch between BT file and STOCK file, kind of like multiboot on a computer if you want.

Im sorry if i got a bit ticked off, but i really dont need posts like "i dont think you should do this"... thats not really good motivation:) even if i didnt have all the pieces figured out yet, thats no way to motivatie someone.
You have to try to succseed... or fail ;-)

Anyways, Thanks for your reply's. I will most def do the clutch later on then.
Also, np denver :) i'd like to know that myself!
