The dealer didn't check the torque and power before tuning (they didn't have a dyno, something I hadn't realised). The blue line on the graph shows the expected power at stock and is from APR's website, but is probably conservative as I think it is for the CJSA which has 30Nm less torque than my CJSB. I have already had it returned to stock and I now have the anaemic yellow line. I still think the most likely thing is that they have used the wrong maps. The transmission is a 6 speed DSG, code QMH. I'm pretty sure that's a DQ250 with a torque limit of 400Nm. For people that exceed the torque limit it seems the problem is clutch slipping, not torque limiting.

They told me the car would be checked out to make sure everything was okay before doing the tune. When I asked for the car to be taken back to stock I asked what map they would use and they said it was supplied by APR. I asked why that wouldn't be inccompatible if APR thought I had a different engine and got into a argument along the lines of "If the ECU accepts it then it must be right". But the branch of the company I got to restore a "stock" tune wasn't the one where they did the tune in the first place -- that one didn't have a dyno. Will contact the original branch tomorrow to check if they'd backed up and kept the stock file. Not sure why I hadn't thought of that earlier.

nta16: The car had always been dealer serviced and was up to date when tuned. It was in excellent condition throughout and there were no error codes. Stage 1 tuning is just an ECU flash or remap or whatever. Parts like intakes, exhausts, turbos come in at stage 2 or 3, which then usually requires DSG tuning. Apart from the tune my car is stock apart from a throttle controller which was added after the tune to make my car driveable again. Will post on the Octavia forum re engine variants later today. Ootohere: It's a 98 ron tune and that's all I've ever used. The transmission is a 6 speed DSG, code QMH. I'm pretty sure that's a DQ250 with a torque limit of 400Nm.

Hi I bought a 2015, 132 TSI Scout and got a stage 1 APR tune for it. It immediately lost torque low down, with power kicking abruptly at around 3,000 RPM. There was so little power that it took a while to hot the power band and I became just about the slowest car at the lights, especially if it was uphill. I was told that was typical for the 1.8L engines and that it was impossible for there to be anything wrong with the tune. A throttle controller helped but it still wasn't great to drive. I emailed APR in the states and they suggested reducing the spark plug gap to 0.6mm. Didn't work. Worryingly they insisted my car had a CJSA engine (250Nm) when it very definitely has a CJSB (280Nm). Eventually I got the local agent to put it on the dyno and give me a report. They told me the tune was producing the amount of power it was supposed to. This seemed ridiculous and I told them to put it back to stock. Immediately I drove it had way less power than it should have. With the throttle controller back on it is much better around town but clearly missing a lot of mid-range torque. When I tried to interpret the dyno report the first thing I noticed was there was no recording under about 2,800 RPM with the tune so i'll never know what was going on there. The second was the weird shape of both torque curves. Even without seeing the figures it seems obvious something's wrong. The APR website has graphs illustrating before and after at-wheel torque and power curves for the EA888 (Probably CJSA) and they look nothing like my actual readings. I took coordinates from their graph, converted ft/lbs to Nm, and overlaid one over the other. See below. So now it's clear that something was seriously wrong with the tune, and APR's agent can't get my car back to how it was. It's been suggested (on an Australian forum) that because the CJSB is an uncommon motor I'd need to get a Skoda dealer to fix it. I've looked into it and got a quote of ~A$3,500 (for a new ECU) plus 3-4 hours labour. Yikes! I really like this car and would love to get it tuned properly or at least back to how it should be, and any insights would be extremely welcome. Some questions include: What is the difference between a CJSA and CJSB? Nobody seems to know. If it were just the factory map my car should at least have the power of a CJSA. Does anyone other that APR do a tune that might work? Can anyone suggest how I might get my current ECU flashed back to stock? It seems Skoda don't do flashing and the people who do flashing don't have the right map for my car. Cheers Russell

Hello all So I became a Skoda owner about eight years ago. They were still new to the marker in Australia and I think they were selling cheap to get a bit of market share. Nobody much in Oz had heard of them but my partner's father was Czech and we've visited family there several times so were fairly familiar with them. I also knew that technology, components and platforms were widely shared among VAG and it seemed like you pick your car, then decide what you want to pay for it - the Skoda price, the VW price or the Audi price (They don't sell SEAT down here). I bought a (2015) 110TSI Octavia sedan and loved it. Interior space seemed tardis-like, it handled as well as my old Alfasud and pulled effortlessly up hills like a V8 of my youth. Alas, a few days after a torrential downpour we noticed a strange smell. Under the front passenger floor mat was a small lake. And then an airbag warning light came on. Fast forward a few days and my favourite-ever car was written off by the insurance company. Now we're on our second Octavia, this time a 2015 Scout. If they import a Skoda plug in hybrid my next car could well be a Skoda too. Though a new member I'm certainly not new to the site, having frequently ended up here when googling stuff. Re my user name, someone at the refinery where I did my apprenticeship many decades ago remarked of me "doesn't he look like a murray cod?" and the thing stuck. Largely because I encouraged it. There are many worse things you can be nick-named in an oil refinery. Cheerio Russell
