No Speedo? Limp Mode

[bionicxr6t05]

If programming is interupted or unsuccessful for any reason it can fatally corrupt the pcm firmware. I would try and get a test one prior to replacing it, got any mates willing to let you use their pcm??

Ill try get my hands on one.

Can I use a ba xt one and have it reprogrammed?

or must be xr6t

[bionicxr6t05]

Nope must be xr6t

[leafy]

ah yeh dont like my chances of that. Unless someone on this site has one they'll sell cheap

. Ill have to keep an eye out. Im really not keen on replacing it unless it screwed cause it sounds like an overtop fix when everything bar speedo and limp mode is running perfect

[bionicxr6t05]

Well really if its whats causing the problem you have no other choice... Theres no dodgy fix that can be done if its stuffed its stuffed. Test it with a known good pcm or bite the bullet

[bionicxr6t05]

I have a spare territory turbo pcm id be happy to let you try but im 99% sure it wont work

yer im up in gladstone so it'd probably be a bit hard to grab it off you.

Is there much success with aftermarket ecus?

[bionicxr6t05]

Yes but in your case not worth it

Ah fair enough, this cars being a very costly excersice.

It sat for 12 months in a storage shed while old mate was travelling before I bought it so im guessing that's part of faults

Might have to look at bolting engine into a little cortina and using it has a drag car or something the amount im spending lol
