There are some un-answered questions about laptops, and finding one that with work with different ECU s. You can still buy from at least three or four name brand companies, laptops that have the ports available to communicate with most all ECU.

Panasonic....MPC....IBM....Dell.....Toshiba....HP. ..... pick your price range, this will narrow down the choices even more.

As far as the Motec M48..about $2300.00 with no options enabled. DOS being used in this ECU is definitly dated, but the M48 works so well one cannot complain. I take that back...I can complain a little. If you want better...spend 1K more and get a no optioned M600. Still worth every penny and my #1 choice. You get what you pay for. What other company has an engineer that would actually answer questions on a EFI forum on Christmas day?????
Whatever one may save on a lower price ECU, he will loose in labor woes (problems) on another. Every one is a new adventure. The only way to get REALLY good and have a great running engine is to stay with Motec or DTA , one or both. It will simplify your life. Not that other systems won't work...I just have such a large MAP file base for the above mentioned, it doesn't make good business sense to keep losing time on other systems. None are perfect, but the customer always wants a perfect running engine..like Motronic.

This comes from about six years of semi daily tuning...........and always thinking about it.
Street cars can involve much more time consumption than track cars for driveability tuning, and you can get a real good starting, running engine if time is no object.
