A lot of people who are adding EFI to a carbureted vehicle or modifying a vehicle that has EFI are doing so because they want to install a power adder. Turbo or Blower.
To run these usually takes very specific code or ECU's. Only a handfull of the OEM codes will handle it. I would like to see a specific list of DIY solutions for boost tuning for each auto manufacturer mentioned.

I really like Code59 on the GM ecu's. Cheap and powerful. How about a list of vehicles that had usable ECU's for this? Memcal's to be collecting ?

Just my 2 cents. Happy to help out where I can. :D
