  • Issue with HDI 90 remap.

    Today I had my HDI 90 remapped by Dyna Tune. Everything went great, was hitting what it was ment to on the dyno as well. After the map went a test drive and it fair pulled, which if you own a 90 it badly needs.

    Tho soon as I hit about 85 mph, car beeps at me, service light comes on and the diagnosis trip computer flashes up an error, Engine fault:Needs Repair. Took it back and they ran a full diagnostic and up pops an error P1621. Control Module Long Term Memory Performance/ Immobilizer Code Words Do Not Match.

    Several maps later the same thing happened. Its always in the 80 ish mph to 90 it happens. Car returned to stock for the time being as the guy tuning it thinks its a hashsum causing it to throw the error. So now just need to wait till the file is looked at more. Thought i would share here to see if anyone has any insight to it or if anyone else has had the same issue. Maybe jamie has an idea.
