Question Can I Use My Handheld after Professional ECM tune has been Done?

My car was Dyno Tuned by Cartek. I was told that I can't use my Old Predator Handheld anymore ? The reason I ask is because I want to put my Drag lites with 28in. MT/Street slicks on for good and want to reprogram my Speedo. Will I mess up my ECM ?

reprogramming for new tires takes about 30 seconds...why not ask them if they can just do it no charge?

Unhappy

I love Dave & the guys at Cartek but nothing takes 30 seconds there. lol. They're always swamped with cars & customer's (but they do have a quick turnaround). I guess It doesn't hurt to try though I wish I could do it with my Handheld so if I swap back my other Rims I won't have to bother them.

A preditor will overwrite the tune that is in the car with what is in the preditor, even if you are only changing tire sizes.

Ditto. I've had this happen to a few customers in the past.

Thanks so much for the Info Guy's. I really appreciate the offer foff667. I have heard that Cartek Locks their Tunes. I'm gonna stop by there Saturday and see what happens. Thanks again for saving me a shitload of headaches !
