Tire change

[69camaro5speed]

Has any one tryed doing a 6a tune with smaller tires with any luck.I put some 275 40 17 hoosers on my 2010 camaro very small thinking I can use them for drag racing then use org tires still for street driving and not changing gears.

I have tryed changing trans tune and ecm tune like 10 times I cant seem to make the abs happy, the stability trac is not happy eather but i can click it off.
I have tryed speedo setting in both controlers drive tire settings ect.

Then seen some stuff about abs module needing programed for gear changes ?

I have done 4th gen stuff never had the problem getting around it
or do people just pull the abs fuse lol seems like a good idea right now
I have done some searching on forums havent found anything

If the tire size is different than original, the ABS module will be unhappy about it;

ABS module needs programming for tire size change.

EFILive can't program the ABS module, ECM/TCM tune will not make any difference to ABS module.

yeah seems like the deal. so if it had same size on the front it might work I am guessing its the big differance from front to back thats the problem

[joecar]

Yes, it is the front-rear difference.
