1.2 tsi remap(anyone with a remapped 86)

[Wonky]

its a different stroking length not that different but there is a difference skoda master tech and service manager told me this when i was getting a turbo

Displacing 1,196 cc, the 1.2 TSI engines all have the same 71mm bore and 75.6mm stroke. They have a cast aluminum alloy block for lightness and die-forged steel crankshaft for strength. This family of four-cylinder turbocharged engines is produced by Skoda Auto at the Mlada Boleslav. All use demand-controlled injectors which eliminate the need for a return fuel system. The single turbocharger offers 1.6 bars of pressure and is equipped with a front-mounted intercooler.

The 1.2 TSI engine is widely available across all subcompact and compact Volkswagen Group cars. This includes the VW Polo, Golf, Beetle, Jetta, Golf Cabriolet, Golf Plus, Caddy, Touran in various power outputs. The list of SEAT and Skoda models is just as extensive and includes the Ibiza, Leon, Altea, Altea XL, Skoda Fabia, Rapid, Roomster and Yeti. Audi also offers it on both the A1 and the A3.

The 1.2 TSI engine was presented in December 2009 for the Volkswagen passenger vehicles and gradually began being introduced on SEAT and Skoda models the next year. Three different output versions of the engine, with increased performance and production costs. All horsepower figures are expressed under the DIN system, since VW is a German automaker:

The cheapest TSI engine currently on offer is the 86 hp (63 kW) at 4,800rpm and 160 Nm (118 lb-ft) from 1,500rpm. First offered on the Golf 6 as an alternative for the 1.6 MPI, entering production under the CBZA internal name.

A 90 PS (66 kW) version of the same 8-valve engine engine was launched on the Polo 5 in 2011. It delivers its output 300rpm lower but has the same 160 Nm (118 lb-ft) torque levels.

1.2 TSI engines also offer 105 hp and 175 Nm (129 lb-ft) of torque on select models. These engines have four valves per cylinder and offer improved performance.

This is all I can find, interesting to find the bore size if different. And the alternative stroke and Pistons used.

Will have to ask local dealer when next in.

Do it! Deffiently worth the money, it's transforms the whole car, overtaking is so much easier, it picks up so much quicker also!

Fuel consumption is dependent on how you drive.

I did a short motorway journey today doing between 60/70 and I was averaging 50mpg.

Here's my dyno graph - Revo

From the 2 posts above, what petrol were the 2 cars on the Dyno running on at the time.  95, 97 or 99 Octane minimum?

It was running texaco super which I believe is 97. I normally fill up with Tesco 99 with the clubcard savings

your revo map is 10bhp short

your revo map is 10bhp short

Revo quote between 129ps and 144ps

What boost is the Revo map running Jay ? (I see you've installed a gauge)

Its running 0.8 Bar of boost, which is around 12PSI

I think revo are going to be the fellas for me to go to once its done some miles

I had mine mapped with just over 7000 miles on the clock. Up to over 15000 now with a recent drop in Piper X filter and the car definitely revs more freely towards the top end

Thanks Jay. What boost does it hold towards the top end of the revs?

I think they were talking poo.

It's the same engine. Everything's the same, just a different map.

Holds boost all the way through mate

So from this it seems all are same volume, but small is 8V and big is 16V.

The chaincam 1.2tsi engines in the fabia mk2 are all 8 valve and have identical stroke and bore.

getting back to the OP , PristineReflections did you get your car remap?

 

I have 1.2 tsi (84) and have tried BHP and Quantum with no luck, saying they've not got the profile for the ecu fitted in mine.

 

Today tried Awesome (APR) with same but would raise with APR if they can get the ecu file and compile remap for mine, could take up to two weeks.

 

Going to try Unicorn at some point

 PristineReflections did you get your remap?

 

 I final got mine remapped November last year by Unicorn Motor Development who are based in Stockport.

 

Dyno before at the wheel 88hp at 5,843 rpm with torque 124.2 ft lbs at 2,452 rpm and Dyno now 120.7hp at 4,943rpm with torque 157.4ft lbs at 2,883 rpm.

It was well worth it more power,

Improved fuel consumption,.

And  have since had a powerflow catback system fitted.

Does the remap enhance chain stretching issue on these engines? Or are there any other negative side effects that can be related to the increased power and torque figures?

Thinking of remapping my 1.2 tsi CBZB and gathering information before I make a final decision....

If your worried about the chain stretching issue then put off the remap and put the money towards getting the chain tensioner upgrade that was fitted to vehicles made late 2011 - onwards. Probably best to have it done by a dealer or a VAG specialist.

I don't think remapping the ECU is automatically going to make the chain stretch issue worse, but everyone is going to be more demanding on their engine when they've just had it remapped for extra power.

My car was produced in 12/2013 so I believe that it has the latest chain, sprockets and tensioner set. It has done 75k km and so far I haven't had any problems with the chain issue. I believe that it will eventually need a new chain set, but I'm aware of the problems it can cause so I keep my eye on it (or should I say a ear...). Furthermore, I change the oil every 6-7k km to ensure that the chain and tensioner are well lubricated. Maybe I'm wrong, but it seems to me that a lot of issues related with the chain are caused by poor maintenance - what I mean when I say that is that the cars on longlife service intervals are more affected due to poor lubrication and often low oil levels which lead to friction and increased working temperatures...

I'm aware that the increased power and torque figures will certainly have an impact on the life span of the chain set, but I wanted to hear from others, which already remapped their car and have been driving their car for a longer period of time/km, what negative aspects did they had to deal with?

Also a known problem with these engines is the wastegate actuator? Can that issue be related to the remapping? Mine had a problem with it. It failed when the car was still under warranty (believe the car had around 20k km). After that I haven't had any problems with it...
