Installed by jpc cc works in 5th and 6th the only 2 gears i would ever use it in!
It has to do with the boss file. I figured that much out at least.
My car is a 2013 GT with 2.97 T56.
With my Stock GT strategy(BLV3), my cruise control works in 6th gear only.
With my Boss strategy tune(DZW2) and no other changes, cruise control STOPS working in 6th and instead ONLY works in 4th. I tried changing gear ratios and other common fixes but regardless of changes, cruise control would only work in 4th gear with the boss strategy.
Strange huh... lol
I gave up trying to figure it out and just enjoy the fact that it works in 6th gear for me.
Good luck!
Thank you, Juic3d! Just to clarify. You have a stock GT and you tried to run a factory OEM Boss 302 tune on it? I did not know this was even possible. How did you get the tune? Is the engine OK with that tune other than the CC? :burnout:
If I understand it correctly than a) It is completely tune related, and b) No Boss 302 (at least with same tune file, which I think means all 2013 Boss 302s) would have a working CC, other than 4th gear. This narrows it down quite a bit.
'13 boss. 2.97 t56. 3.31 rear gear swap. Cruise works in 4th and 6th. BBR tune, I installed the trans
Bucket, I see that you have a 13 boss and CC works for you both in 4th and 6th. Did you install the JPC conversion box from their kit? Did by any chance try the CC after the conversion but before loading the BBR tune? That is with the OEM factory tune? Did the CC work with the factory tune the same way as with the BBR tune? Thank you.
What ever the box was that came with the swap. BBR got me the T56 , also can't recall tune order. Cruise on my car has always worked, but with t56 only 4th and 6th. But I already had a tune from BBR (my boss is not stock). I did the trans install, so I did nothing crazy. Just by instruction for hooking up box
Bucket has our conversion box
OK. Thank you guys. It seems that the problem is clearly tune related but even on a 13' Boss with correct tune the CC should work in 6th. We will investigate further.
What strategy do you have ?
Do you mean factory tune code? All 2013 Boss 302 have the same code and all 2012 Boss 302 have a different but year specific code. I have the DZW2. I am running a base AED tune from Shaun right now and will switch to his performance tune when we load the tune. The car is in the shop for additional mods. His base file set the 1st, 4th, 5th, and 6th gears correctly but because I gave him wrong info for the 2nd and 3rd gear ratios his base file's ratios for 2nd and 3rd gears were slightly off. Maybe this is the reason why the CC is not working but I am not sure because the differences were very minor (e.g. 2.07 vs 2.1) and only for 2nd and 3rd gears. The 5th and 6th gears were already set correctly. The final tune has the correct gear ratios for ALL gears. I will see if CC will start working in 6th gear with the tune that has all gear ratios correct. Why did you ask?
DZW2 is the box code
If you plug the SCT in and go to get info
it will have the strategy
Car is in shop. I will load new tune at the end of February. I will find out the strategy that time. Thank you.
I'm interested too. I don't get why my 4th works. Has to maybe be something the computer is seeing in ohm may. Who knows
Would like 5th and 6th to work but don't matter
