custom tune i brlieve?

 

The person who programmed it can "unlock" different options including idle, axle ratio, timing, ect. It's a PITA if they lock it like my tuner did, like I didn't pay him enough.

 

oh alright because i just got one on ebay and the guy unlocked it and i put the 91 tune on it but was hoping to also change my speedo because i have 3.73s

 

did you check to see if you have the user options when you start the flash process?

 

uh idk i dont think it showed that. it just said install tune and i selected it.

 

You should be able to change other options as well. Now try reflashing it again, but select an option that says something like change previous options or set options or something like that... it has change in it lol. And it should bring a list of options, one of them being gear ratio.

 

could me have an sct eliminator chip **** the tune up because i have on of those on there too and i am meaning to take it off just been too lazy

 

Ummm... i wouldnt know, but it'd prolly be good to take it off though.

 

oh alright ill take it off tomorrow and see if that works.

 

But there should be an option to change the tune preferences a little bit. before you okay it to download, it should say
1. Change Tune
2. Download Tune
3. Save tune


Or something like that, idr its been a while. But you click on the change one so you can modify the tune to your likings on little things like fuel type or gear ratios.

 

well all mine said was when i plugged it into my car was turn key on dont start so i did that then it gave me the option of install tune, read dtc codes, clear dtc codes, and like device info and vehicle info and stuff like that. Then i clicked install tune

 

Did it actually install the tune? Like turned your fan on and showed a load bar and everything?

 

no it didnt show a load bar. i just took out my sct chip and went to plug the tuner in and it say wrong vehicle now

 

put the chip back in, put the tuner back on, and go to return to stock then take out the chip after thats done.

 

it keeps saying power up msg time out. i tried to put the chip back in and selected return to stock and it said the same thing but my fan turned on its pissing me off

 

hmmm... have you ever uploaded it on your car where it actually changed the stock tune to a performance one?

 

no i bought the tuner used off ebay and got it yesterday and the guy said it was unlocked. before the tuner i just had the eliminator chip in there then when i got the tuner i tried loading the 91 tune on there and it said power up msg time out but the fan came on. Then after i took my chip out and tried to upload it, it said wrong vehicle. I tried after that to put the chip back in and returning it to stock and it says the same power up msg time out bull shittt

 

It seems as if its either locked or not a ford sct tuner.

 

you can't flash with a chip in there.
Flashing Tunes

 

alright i got it working now apparently it was half locked meaning i could download the live update and all i had to do was unlock it. I installed the tune and it runs like **** so for now im just gonna use my chip and get a custom tune put on the tuner

 

Do you have the correct fuel for the tune? You should only have a tune for the lowest grade fuel you have in your tank. No mixing and still using the higher grade tune.

 

I have a question...
Say the car is sitting in my driveway with half a tank of 87 octane fuel in it and I want to tune it to 93 octane, should I empty that tank then fill up with 93 a couple times to flush out the 87 THEN tune it or wat?

 

I would just suggest purchasing a custom tune, with your mods, you'll get a better gain out of them than with just the stock ecu... try bamachips, or brenspeed.

 

well i googled the problem and a guy bought a used tuner and a cai and had the same problem. Apparently when you get a tune its for the one car that the tuner is locked for and thats it. The guy did the same thing and when he went to start his car it ran like ****

 

as for your octane question it should be fine as long as you dont keep running 87 for a 93 octane tune. i ran 87 once and my chip is tuned for 91 and it didnt hurt my motor but i only use 91 now

 

well i put my chip back in for now. im gonna get a custom tune next payday

 

I was plannin on gettin a custom tune with 93 octane from American muscle

 

Your fine just put the 93 in it, atleast a half a tank and then just use 93 after that bro
