Need to update new gearing

[sardinecan]

I'm swapping from 3.42 to 3.73 soon on a 2006 Chevy Tahoe 4x4. How do I make this change on my tuner? I'm running a Diablew tune, do I need to send my files somewhere? It's been a while since I've made any changes. Thanks for your help!

select the custom tune to install... then choose to Modify it when it asks you... go to the gear/axle ratio setting and make your change... then exit back out and install/apply the tune...

[sardinecan]

Awesome, thanks for your help with this!

Hi again,

I went into modify tune, but did not see an option for gear axle ratio. Please let me know if I need to send you my tune. Thanks!

[06MonteSS]

it's in there somewhere... Either gear ratio, or axle ratio, or it may be under the speedo correction menu...

[sardinecan]

Thanks. I went through every menu today and couldn't find it.

Is it possible I need a firmware and database update (see screenshot attachment)?

I found and used the Update Agent. It loaded some files to the device, but still no change. My firmware info now looks like this.

OK I did manage to update the firmware.

Still not seeing an option for gearing change.

Bump for visibility. Thanks!

Not sure man... it should definitely be there somewhere... contact tech support... support@diablosport.com

[sardinecan]

Thanks for the response. I'm working with support now.

[sardinecan]

I've got all the lastest firmware and updates loaded now. Still not seeing a gear/axle ratio option. I've worked with support and haven't been able to get this sorted.

@06MonteSS is it possible I could post/send you my backup and lasttunewritten files and you could make the change for me? Thanks!
