I question about ecu's

[stu9]

I may be about to buy a complete set ie ecu, transponder ring, fob with chip and bsi.... I'll need it for a 110hp C5. Are there any number on the ecu ect to verify this. Whippy said if they had the security code it would say, but if they dont have it, how do I/they tell.

There's a sticker on my drivers door pillar that say's mine's the 110 model, but I wont be near a car that I'm buying the stuff from to see this. Infact, I dont have my own code
