Ranger Mods

Dear all,
I tuned AT/BF Goodrick Tyres 265/75/R18 for my Ranger
I changed in BdyCM 726-12-01 xxxx 09AB xxxx with Forscan
But appeared Check engine indicator and DTC P0700 in PCM, and I cannot reset or relearn PCM.
What can I do? Thanks

Did you do a save of the default values before you changed it?

You should be able to do a restore.

If you didn't, Stewart is the one to help you.

Max size manual 0987
Max size automatic 0977

This will get rid of you DTC. There are pages and pages here regarding this.

Enjoy.

Hi Stewart, can you link a few of the pages or is there a sticky? Also what is the default values compared to the maximum?

Default is usually approx 0934 0938.
0934 = 2356mm circumference


Max size manual 0987 = 2439mm circumference
Max size automatic 0977 = 2423mm circumference

There is a 4% fudge factor involved and this is what you see is missing on the instrument cluster.

or DTC

2.0 may be different and could be lower or higher before a DTC.
