I bought and fitted a pre-flashed "plug & play" ECU from Livewire via eBay and thought I'd share my thoughts on this low-cost offering:

 

(Fabia PD100 Combi) Prior to this ECU Remap I had a (albeit fancily packaged) resistor on the fuel temp. sensor wiring - this (approx 170 ohm) worked to an extent; torque at low revs and just coming on turbo was improved, but as it approached 3k revs there was little (if any) difference to standard. Main difference was at low revs before turbo woke up, decent response and would happily pull a higher gear.

 

The ECU was for PD100, claiming to take it up to approx 140hp but of course without a rolling road session there's no way of knowing actual figures for any individual car. Fitting was easy enough (filter housing gets in the way - easier to do with this removed). I had to reset fault codes (the seller mentioned this would be necessary) but no problem once done. I haven't had a Furby remapped before, so only have the resistor mod and standard to compare with. If I get a chance I will try to get some 0-60, 40-70 etc times but not sure when my next free day will be.

 

The main impression was one of smoothness - no sudden torque spikes, just a smooth build up of power - very clutch friendly - and pulls into the 4000s (as standard it seemed to run out of chuff by 3K, it was still increasing but no urgency if you know what I mean). Very "drivable". This encourages using the revs and not labouring the engine or having a huge dollop of low-rev torque break traction or stress the clutch. Gear changes seemed smoother though this might be placebo effect. Smoke was noticable by its absence  . The Fabia definitely feels livelier, like it has lost weight or had rubbing brakes before. I don't know the actual figures, without getting it on a RR, but it would be interesting to see the torque curve. Because the power feeds in gradually without a sudden surge, you don't realise how quickly you're getting up to speed, but you are getting there quite quickly. Rain & traffic put paid to any further testing but overall I'm pleased so far - especially with the price ! (also get to keep the original ECU to put back to standard when selling)

 

Tempted to see how the resistor mod affects the map, but for now I'll get used to how it now drives.

I've mapped 2 Fabia PD100 to around 140bhp with MPPS and those little things fly, the smaller turbo spools up quickly and you can certainly feel the difference, the power to weight ratio make them agile quick cars.

 

I can post expected torque curves of 2 different maps as seen in EDCSuite, they are quite peaky below 2k but that is because the turbo spins up quicker than say the 130.

 

Don't use the resistor mod along with the map it will mess the fuelling up and you will end up with smoke and no more power.
