REVO Stage 2

[tinbum]

Ok, here is my situation

I upgraded to Revo 2, but lost all the low end boost etc.
Dont get me wrong, it goes like a fighter jet high end, but if I wanted a V-Tec type set up, I would have kept my Honda.

So my question is: Is this a typical Characteristic of stage 2, or does it simply need adjusting. Surely the timing can just be brought back slightly to provide more low end power. If not, then in my opinion, Stage 2 is a bit pointless unless you like driving on the red line.

The obvious draw back off having the power all at the top end is fuel economy. As we all know, driving on the turbo is much more efficient that driving off the turbo, so that sucks too.

Anybody and idea's ?

TBH I've not heard this before. It might be worth you having a play with an SPS3 - do you know what settings you are currently running? (boost/timing)

Looking at your mods you are also minus an air filter & FMIC, both of which would help, as per Revo's recommendations for Stage 2.

A car will be faster with more power is at the top end. Having the power spread so it builds progressively and continues to build throughout the rev range will give you a faster overall car, compared to having lots of low-end power with not as much up top.

Stage 2 doesn't mean more power everywhere. It effectively changes the way the power is delivered, improves midrange and top end power and makes the delivery a bit more linear.

Revo can be adjusted though, so head back to your Revo dealer and tell them what you are and aren't happy about and I'm sure they will be able to adjust it for you.

I have done air filter etc mate, just forgot to put it on the list...lol

Hey Rob
I totally hear what you say dude, but not sure I understand the theory of stage 2 in that case. Sure the point of changing the exhaust, filter, fuel bar reg etc etc is to enable more air and fuel etc, thus being able to safely generate more boost etc ? So why doesnt stage 2 mean more power everywhere ? I dont understand why it only means the rev range changes. Surely a car would be quicker if the power was constant and smooth right the way through the rev range. I can not see why with the standard turbo this is not possible. If I had enlarged the turbo and there simply wasnt enough exhaust gases etc to spin it up low end I could accept the situation, but nothing has changed.

Am I making sense dude ?

I know where you are coming from! I had a custom remap one too mines! but due to high flow decat and straight through system! ive lost alot of low end torque! i then fitted a new cat and a new silencer! The car now shifts with a greater pull!
You just need to balance it out!

 

[Feel]

Stage 2 does request less boost lower down than stage 1, so it'll feel less urgent at lower revs.

Also, on the LCR, they "recalibrated" (not sure if that's the right word) the throttle position, so you have to push it down more for the same effect.

I know at least one person that's gone back to stage 1 because they didn't like the way it drove. Or perhaps more correctly, stage 1 suited they way they drove better.

Ummmmm
Thinking I might do the same.
I need somebody who knows Revo inside out really. Any recommendations ?

sounds like it's been set wrong...

St2 has a much broader range of adjustment on the SPS3, so B9T7 (for example) that you might have got away with on St1 is not approriate for st2 IMO

B9T7 ?

How about your Revo dealer who installed it? They should know enough to set it up properly.....

Most dealers take the car out for testdrives etc too, and adjust as/when necessary.

Boost9 Timing 7

Arrrr ok.
Wasnt aware you could run these on stage 1 !!
Stage 1 is around 5 to 6 normally with standard coolers ?

 

[m0rk]

that's why I put (for example) after it

many people turn the wick up too much, then moan about power delivery

Yeh agreed, but im not faulting the way its been installed, Im trying to get my head around why the Map itself.

This is as I see it (correct me if im wrong)
All I have done for stage 2 is the ususal mods, exhaust, airfilter etc. So in theory this will allow me to run more boost because of the fuel and air mix etc, so why and how does this effect the bottom end ? We know that the car can run higher boost bottom end as thats what you get with Stage 1. So why with stage 2 does it have to drop off low end boost to get high end it doesnt make sense, the restriction on the boost etc is because of the breathing airflow and fuel etc. I dont understand why the low end boost cant remain.

Is it beause the car simply cant handle more boost down low without it causing issues ? So in order to increase the boost high end they have had to lower it at the bottom ?

Am I making sense ?

 

[tinbum]

Mork.....any ideas ?

 

[m0rk]

it probably just needs some logging, and tweeking with the SPS3 really.

BUT, I'd guess at probably B8 T5 would be a reasonable setting to start at, if you're missing lower down torque/boost

Ok cool thanks
I going to speak to Revo tommorow to find out what they suggest, but need to do something with it, its driving me crackers !!!
