I totally disagree with the previous post !!
I actually have a Mines ECU fitted to my 90 Celsior so I'm actually talking from a position of knowing .
If Sideshow has actually had a Mines ECU fitted I will take it all back , but I get really pissed off with people who post so strongly about something they really know nothing about !!!
Other people actually read that stuff and believe it , it's fine to offer an opinion but the previous post is way more than that .
As a point not only have I fitted a Mines ECU to my 90 Celsior but my brother in NZ has also got one on his 93 LS400 and he was totally blown away by the improvement , he expected it to be better , but just a little bit better , not the huge improvement in real life driving .
Both of us agree it's money very well spent .
My Celsior has gained about 30 to 40 HP , not only are the shift points changed but how it shifts has also changed , my redline has also advanced to 7,500 RPM , the car is just stronger and crisper everywhere but even more so above 2,800 RPM , economy is also slightly better .
In side by side comparo's with 3 other Celsior's mine just walks away .
It's noticeable by other Celsior/LS400 owners even when they are just a passenger .
For some-one who wants an improvement but isn't into turbo's andf such like it's a GREAT thing .
The best thing is it's plug and play , fitted in about 20 min's , not every one has the time or the money OR the desire to fit aftermarket ECU's and then have to tune them !!
Sideshow it might not be your thing , but that still doesn't mean it's not value for money .
