Bumper Caddy

ok so i have a fully built (for the most part) single cam turbo and i just got my datalogginfg cord and all that and im tryin to change my a/f to a little richer and open up the injectors duty cycle a little bit and i have a friend who can tune but has never done it with crome so im tryin to make some adjustments for now but when i go to start messing with it it tells me that i need to connect to a connect to a com/port and i have followed the instructions via tuningwithcrome.com and its telling me it cannot connect to the ecu. i've been at it for like 3 days now and nothing. anyone got ideas?


summary: crome, built single cam turbo, crome saying it cannot connect to the ecu.

First of all, what ECU is it, and do you have a chip in the ECU with a Crome program on it?
Also, you've got the key in the "ON" position, not the accessory position, right?
It's been a long time since I've used Crome, and I'm just going from memory. I'm sure someone else will chime in and add something more useful than I did..

B-Well
