ITG bhp increase

[robjnr]

Yes and from what i understand likely to break the first time you remove it anyway!!

Removing mine in 10 mins to put the new filter in b4 off to have it REVO'd (probably minus the engine cover!)

Shame it is wet today, not going to get the best out of the remap with my ditch finder wheels

Get the results up after you get revo'd mate be interesting to know before and after results

FYI mine was the following if this helps,

Revo Stage 1

RR before remap
253.8 BHP
224.2 lb/ft Torque

RR after remap
317.0 BHP
306.6 lb/ft Torque

I want to do it again now i have the ITG at AMD RR to see what it comes out at...

Be good to see what other people get as i know its abit of a dyno lottery!

 

[owen lcr]

thats good power mate, you will be well up on that if you have now got an ITG,

 

[Adam's Cupra]

you will be well up on that if you have now got an ITG,

Do you think so? Im interested to see what Stage 1 is putting out now.. I know its not all about BHP figures but would be good to know

 

[owen lcr]

well if it was going 317 with OEM intake then you will defo get more with ITG... I have never had my car on the RR but cant wait to do it.

By the sounds of this map your looking at your car is going to be abit of a beast!

 

[owen lcr]

hope so, no idea what figures at has and not really that interested but its always good to see for a laugh. you planning anything else with your car

 

[Adam's Cupra]

Well Stage 1 was going to be the start and finish of modifications.. but it’s not looking that way now..

I’m not sure what I will do next, but I want to try and get to a meet this year to meet some people and see some of the cars on here.. I’m sure I will get some ideas of what to do next..

ITG quote 40hp, on a standard car with the ITG fitted it made 290hp.

I would be very interested to see the proof.

Remember ZBoyds car made almost the same figure with the Dbilas as it did with the ITG intake, and the Dbilas doesnt give anywhere near 40bhp gain even on a mapped car.

 

[owen lcr]

but he is going from stock to ITG so will defo get gains. im sure you should be mid 320hp with the itg which is bloody good for stage 1 +intake

the intermittent (car specific) Revo stg 2+ flat spot.

I have a mod planned for April, and it will be interesting to see it it resolved this issue for those that are having this problem.

I still maintain it is hardware specific (not the code), but we will see.

Here is my take on this.

Having logged Owens GIAC car at the weekend, fuel pressure was logged at a max of 126Bar. My car with all the same mods and Revo S2+ peaks out at about 132.49Bar. Boost on Revo was also higher than GIAC based on boost setting 8 for what its worth.

The OEM fuel return valve is not rated as high as the code commands and the flat spot occurs when the request for fuelling is at its highest. The RS4 valve removes this limitation.

I am willing to bet that the reason for the flat spot issue is that some cars will have a Monday morning or Friday afternoon valve, hence the reason some cars do it and some dont. I am also willing to bet that the reason more Revo cars appear to suffer is because of the higher demand for fuel on their map combined with the compromised valve.

I am actually trying to find a fuelling log of my car with S2 code to see what the max fuel request was vs S2+. As the S2+ code is based around an uprated mechanical pump, and knowing what Revo said about it at the time, it was specifically designed for cars with uprated fuel pumps and the request for fuelling was a little more advanced than it was on stage 2.

Therefore, my theory would be that the issue is hardware related based on demand from software, just as it would be problematic having a standard exhaust/fuel pump on a car with S2+ code. In other words there is no issue with Revo code.

When I get the RS4 valve fitted next Thursday along with the diff, clutch, arb's, WALK, short shift, catch can, diverter valve etc, I will be able to confirm this ASAP. Hopefully it will also get rid of the damned jingling noise the car has had for some time too which I also believe is the fuel return valve shitting its pants

In addition, I will also be speaking to Kev to see if Revo will be doing an equivalent of the extreme file for cars with the uprated valve and a bigger intake - the prerequisites for the GIAC extreme file.

Not doubting that, but I seriously doubt a 40bhp (near remap) gain on a stock car with the only modifcation being an ITG filter.

^^^ +1 horace, i say more like 20ish


im sure they will need to do a new map to try and keep in touch with GIAC, i still think it is the Revo software that is requesting to much fuel above 5000rpm (130bar being limit for hardware), you said yourself that revo requests 132bar and it just cant have that from the standard hardware valve thus why the rs4 valve solves the problem.

when you get your car in to have the goodies fitted "i would be my wage packet on that it will cure the flatspot", i also cant wait to see how your car handles the extra power when you get it home.

If revo do decide to go for an extreme "equivelant" map then i think you better hold out on getting a new intake horace as i have no doubt that their new map would also require a 3" intake. This is all my point of view but if GIAC are seeing figures between 380-390 with the 3" intake im sure revo wont be far behind with their updated map.

heres hoping anyway

I have this noise too, and having had the fuel pump checked and found to be OK, this opens another avenue for me to check.

I'm sure JBS just thought I was mental, but the noise is there, and they just pointed the finger at the code so there was nowhere to go from there. Hoping to get all this looked into with RS4 fuel rail in the next few weeks.

This was on Stevep's car on the golf forum however it had every stage 2+ mod apart from the intake. Its in the review section if you want to have a look.

Doubt Revo will do software to support a 3" intake pipe as they got ITG to do an intake or it was developed on Revo's car.

Not quite a stock car then

fair point but if GIAC start to make more power than revo (not saying they will) im sure they will do something about it.

Not sure they will. The thing is that GIAC have made numbers claims in the past, and the cars with GIAC software failed to live up to the claims.

I would be interested in seeing a genuine 390bhp out of a K04 car, but I would fear that there may be a catch or fly in the ointment somewhere.

 

[owen lcr]

well when i got my GIAC hammer map istalled the claimed figure i was told was around 350-360, which as far as i know my car is pretty much running, i know 380 figure was thrown about but i dont think it was from GIAC, just people trying to get a reaction.

there is never going to be a massive differance between and car map company as they all do the same thing with minor differances, ie, boost, fp, etc.

if i get up to around 370ish bhp with the extreme i will be happy, any more i will be delighted.
