1.0T Engine upgrade?

Post by Niitti » Tue Mar 23, 2021 9:23 am

I consider buying a Corsa E with the 1.0T engine. Of course I'd like to have the 85 kW version but they are very rare in my country and are also considerably more expensive. The 66 kW version is much more common. Apparently these engines are mechanically identical and the only difference is in the software of the ECU.

I wonder if it would be possible to replace the software in the ECU to upgrade the 66 kW engine to have all 85 kW? I know that remapping is possible, but I'd really like to use original map by GM and not some aftermarket one.

I bought the 1.4T 74kW version new from the dealer because it was cheaper than the 110kW. I got it remapped on a dyno by the best guy i could find, he managed to pull off 135kW (7.1 seconds 0-100 km/h) and it works like a clock for a year already, and i drive daily. They indeed are mechanically identical. If the guy who remaps it knows what he's doing it's possible to pull off like 100 kW from the 1.0T engine without any mods. 85kW is indeed a very safe tune, there's no need to copy the original map from the stock GM version, but it is possible.

The most noticable difference is from 3500 rpm up to the redline. Below 2000 rpm you can't feel the difference, at least not on the 1.4T. In normal driving conditions i always upshift just below 2000 rpm (i'd assume 3000 rpm on the 1.0T).

Do you have to inform your insurance company of any remap ??

obviously... its then non standard, a modified vehicle.

Not sure how they would be able to tell... but if you had an accident and then it was discovered, undoubtedly gives them an option to refuse payout.

The other thing to consider is does the vehicle have a warranty, as if so likely Vauxhall would claim its invalidated... they told me this when i enquired about fitting heated mirrors!
