hi, i have a 2004 octavia VRS in india which is 150 bhp stock(its how they come here). I wanted to get my ECU remapped which means i need to send my ECU to the UK.

Can someone help me with which one to go for. keeping in mind that the most widely used fuel is 93 octane here

Choices are Jabba, Revo, Custom-code and AMD?

I spoke to jabba and they recommended a remap with a boost controller as i can switch when 97 octane fuel becomes available. Is it simple to fit the boost controller? Also, can i switch the remap back to original when giving for service?

Revo said that 93 octane fuel should not be a problem with their remap..

as did AMD

Please help!!

Personally i would go Custom code / REVO / AMD route as the boost controller may not be easy to fit and get to work correctly. Someone will advise you better i'm sure

Boost controller is not a DIY job.

If you're worried about your warranty and want to switch between programs...it would be better to go REVO/APR/AmD.

Where about are you?

I'm also not clear how a boost controller will adjust timing. Also you would have no way of knowing it was set correctly without access to vagcom.

Custom-Code would be my recommendation and I'm confident they could map the ECU to whatever fuel you wish.

I am based in Chennai, India...

Details of Jabbasport's electronic boost controller can be found on their site here. Go to Products then Boost Controller.

DGW - That just says it adjusts boost so I'm still no clearer on how it adjusts timing. :confused:

I understand that as the boost setting is reduced, this reduces the air quantity flowing through the MAF. This in turn results in a different ignition point on the table (map) being used, and that point will have been mapped as necessary to take account of a lower fuel octane rating.

The MAF reading affects fueling not timing. You could have a map with high timing and low boost or low timing and high boost the two are not related. The amount of air effects the amount of fuel required. Timing is effected by temperature and fuel octane rating.

Even if the boost controller does alter timing, which it could be then would be a timing controller, you would need vagcom to check it was set correctly so that knock and in turn retard were kept to a minimum.

Clearly you know more than he does and I am sure he will be interested to read what you say.

I know how the ECU works and timing isn't altered from MAF readings. However it's possible that the boost controller is actually a boost AND timing controller. However this would be a poor compromise as why should you run less boost just because you are running a lower octane fuel?

If Michael does read this I'd be interested to hear from him what the Jabba boost controller actually does and how an end user can use it for setting timing correctly without sacrificing boost unnecessarily especially without use of vagcom. If vagcom is required then the customer needs to know, especially if they are in India where it's gonna be a bit more difficult for a 'nearby' member to help them out.

I'm not questioning that Jabba can provide a map suitable for 93ron fuel, it's just the suggestion of using a boost controller to acheive this seems strange.

Eddie, I think it is just what it says on the tin, a boost controller. They provide a map that will run on 93 Oct fuel, you can then play with the boost levels and thats it.

As you say, the guy is in India so aftersales is going to be "dubious" whoever maps it, ie plenty of advice but that is about it.

Is there an Upsolute / APR / Revo dealer in India does anyone know? If there is, my advice would be to go to one of them and get it done rather than purchasing from a uk reseller.

After a quick check, the answer would appear to be no. Although I'm sure one of our other Indian members has had some tuning carried out.

That's what I thought but it was Jabba who recommended the boost controller for this application. :confused:

I think APR and Revo do 'of the shelf' 93ron maps so maybe worth looking into that. Alternatively APR +vtune +vagcom or Revo +SPS3 +vagcom could be used to acheive the desired effect but will work out quite costly.

Perhaps Jabbasport were not aware the customer lives in India? Moreover, AFAIK the variable boost controller is only available for fitting at and by Jabbasport.

look man no offence but 93 octane? i didnt think the car is even designed for that... must be pretty bad when it comes to tuning in India. Anyway, i have an octavia rs which i bought from romania 2004 and it comes normal with 180hp, 235nm torque, i got my cars flash tuning, at dimsport, italian company, they have a branch in most countries in europe, the guy that does the remap is a friend of mine. so he changed the soft and customised the maps for extra power. i put my car on the dyno, results, 231 hp, 398 nm torque, max speed was 287 km/h.

In greece you can get the octavia rs model in 2 versions, normal, and octavia rs abt its called, straight from the dealer, octavia rs abt has 210 hp.

if have bought the normal one with 180, u can always send ur ECU to germany or uk and abt will change the soft for 210 hp, it costs almost 1500 euro to get that done, in my opinion its a waste of money, u can get a program from another less known company for 1/3 of that money, i payed 350 euro for my flash tuning and i have 231 hp on the dyno, and the car is really fast...

dont waste ur money on ABT or AMD horse**** (of course this is simply my opinion any1 else can think what they want )

thers one more very important thing that evry1 keeps forgeting, what boost controlers r u talkin bout? were talkin bout kk03 turbo here, i mean how much power can u possibly ever squeez from a k03? even if u somehow managed to get the perfect map for all variables, the perfect program, i dont think k03 could actually give you more than realistic 230 horsepower, with filter and exhaust! its not technically possible...

so why would you really need a boost controller when ur running a stock turbo, to improve on wat??? the changes would b minimall for the money you would pay.......

The boost controller we were talking about is used to, in effect, detune a remapped engine in the event that you want to use a lower octane fuel, or return the map to near standard when the car is with the dealer. It is designed for use with ECUs which have been remapped by Jabbasport.
