Post ECU correction for larger size tires?

I've installed 205-60 x 15's on my 2005 SES with Pulse brand wheels.
The odometer in now reading low as is the speed-O.
The original tires were 195-60 x 15's with a 861 rev/mile.
the new 205's are 845 rev/mile. Doe's anyone know a simple way to correct
this difference without purchasing a programmer and flashing the ECU?

BTW: I have a 2005 SES Wagon ( manual trans ) that I tow with alot

Some mechanical places can reset it for you. The next time your around a police man ask him if he knows a place. Here in virginia they have to go in and have it checked every 6 months.

Send a PM to acidburn02zts on focaljet. He has been using a repeater circuit to modify his speed sensor signal.

I've read of these divider circuits. That's what I think will do it for me. Thanks.
