Except, for one issue; The ODBII ready status is never set because of 2 Porsche codes:

P1126
Porsche fault code 356, mixture adapt, lower load range B. 1

P1133
Porsche fault code 358, mixture adapt, lower load range B. 2

Both occur at about an hour after a full reset. The O2 ready status are good to go.

This hasn't been a problem until last year. Every time I had an emissions check (eCheck) the ODBII fails and I had a tailpipe check. Unfortunately, that option is gone; Ohio has moved to an ODBII check only for eCheck. So, my tags expired.

I've been trying to get Softronic's attention on this since April this year (2020). I've emailed, called, left numerous messages but no response except for an initial email request for the codes. I've offered to pay for the help. I can't get anywhere with this.

I assume that either Softronic is no longer supporting customers or at least no longer interested in my business.

So, I'm looking for alternatives. Anyone have suggested for either:

- A company that can sort out the adaption code issue with the Softronic software

or

- An alternative software solution.


Many thanks for any advice,

Paul

Not surprised that you have emissions issues as the codes are for lean air fuel issues on both banks, P1126 is for an overly lean condition; and P1133 is for the same thing on the other bank. It looks like you have a vacuum leak somewhere in the intake system, which is causing your issues.
