While this answer is sorta on subject but also sorta not on subject, The ME2.0 ecu's can be swapped for ME2.8 ecu's which are easier to hack/clone and mod tuning params, there are a whole host of sites with guides on the swap and if you intention is to tune/mod later in this might be a route for you.
Also years back when i use to modify OPEL engines like the C20XE we were able to buy a adapter that went over the original chip and would act as it's replacement , I personally sent off the ecu for the fitting but many DIY'ed it too, also a alternative option as you can also upgrade the cpu's options too, in our case the upgrade added boost control and wideband input to a stock bosch ecu from 1990. I dont know if people still sell these items or the fact that cheap DIY ecu's can be had that superseded the need.
it might be a option to turn too if hacking the original device runs into issues.
