best way to run two tunes.... - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I need to be able to run my N/A tune and switch to my nitrous tune easily. What is the best way to do this. Does anyone make a simple tune store box that will let me switch back and forth from two custom tunes quickly.

maybe tune it into the TC/SC button

many fullsize trucks use the tow/haul (in the automatics) to switch between tunes

yeah but i would still need something that would store the tunes.

i don't know exactly how it works, but the trucks only use one ECM - it has 2 tunes that switch when the 'abuse mode' button is activated/deactivated. i was thinking this principle might be able to be applied to the traction control button because it switches between 4 different settings that are all stored in the computer.

try calling any of these guys - they do this stuff all the time (with the trucks anyway). they might be able to recommend something:
justin @ black bear performance - 530 304 9934
allen @ nelson performance - 210 626 0278
jesse @ wait4me performance - 574 267 3630

you can also use a simple toggle(6 terminal) switch/resister to the intake air temp sensor, when you flip the switch the iat sensor see's a set value based on your resistor ,, then in your tune program how much nitrous retard for that same temp reading

or if you need more than just a timing retard, you could get a spare ecm and swap them for track/racing,, they can be swapped in minutes

I would say 2 ecms for the safest route.

No, i need to be able to shitch programs on the fly. Not have to stop and change anything out.
