Oh yes, the F40 which was made famous for it's comical turbo lag and faliures if left out in the rain. Ferrari have now stopped using that ECU and have moved on. A 458 would muller an F40 for drivability and performance and that is their bottom of the range product.
If you take a std loom out of a cossie many of the wires are corroded too, a new loom and a new ECU transforms the reliability and running of the cars plus you can map for a more lively engine.
the Weber Marreli is like a 486 1990's PC compared to an Emtron as 2015 Apple Mac
