I'm VERY interested in the RB REVi but I'm starting to hear sporadic reports that people that have had it on for awhile are noticing that the car is going back to performance similar to what it was before the install. It's as if the ECU is learning and compensating for the changes. I hope it's not true but I would like to hear from the current REVi owners.

Now that ya'll have had it on for awhile, are the improvements still there? Has anything changed? Update us please!!

 

I'd believe it...our ECU is one step away from Cyberdyne systems T1000

 

I've had the REVi installed for a couple of weeks now and I still can tell the performance increase. Plus is sounds fantastic with the RB exhaust!

 

lets hope not you would think racing beat would of tested that to make sure there product is up to there standards.

 

I've had mine on for over a month now - longer than most since I was one of the prototypers. :D Several hundred miles now, and definitely still notice a good improvement. I also have no idle issues or problems with it at all.

 

i really hope thats true because i just got mine on tonight and i really love it. why do people always bash this car? it really sucks that the gt boys have to envade our club. i want to talk to rx guys not sti or blue eyes guys ha ha ha :D

 

Mine is howling the same thru the power band

You could always do the battery mod to speed up PCM resets if you need to.

 

Did you replaced your plugs with the RB spark plug wires? i wonder what performance it could be with the RB ehaust and REVi?

 

The same "phenomenon" has been experienced with intakes, and all other mods, on about every car in the world.

It's called "Getting Used to it". After a while you just don't notice the gains anymore because you forget how the car used to be. It feeds all our desire to get another mod so we can get that feeling again.

 

Its all in your head. I though my car was faster a ram air pipe. THen i took it off a week later and it felt better than with it. But i think its all in your head, you just make yourself thinks its faster, or slower

 

Your head plays tricks on you when i purchase the canzoomer unit i thought wow this thing really moves until i had it dynoed with it on and off long story short it was taking power from me . about 8 hp

 

Sounds like an un-tuned story unfolding

Did you spend time tweaking the maps you ran?

 

no i sold it , thats when i acosta motorsports told me they were untunable and garbage

 

Mine has been on for 3 weeks now. Still smoother idle & more pep than before. Does not appear to have increased gas mileage after 2 tankfuls.

 

huh? .... the results of tuning are undeniable for those of us who have done it. It does have a real, measureable effect on improving A/F in open-loop. I don't know how anyone could come to this conclusion. The data supports exactly the opposite.

Back to the topic. I do wonder if the ECU is killing the gains I first felt from REVi. Not that I think the power is diminished. There's no way to measure long-term changes with a butt-dyno. But my LTFT is sitting at 3.9 now. I wonder if it will continue to creep up as the ECU continues to **** me off...
