Default Rev Limiter on '85

Has anybody had success in altering the factory preset? Tunercat shows a MPH fuel cutoff. Thanks.

What does yours rev to. I've seen mine at 5700. The power drops off so hard I wouln't want it to rev higher a little lower would be nice. But then again my engine is stock.

I remember seeing a patch how-to somewhere that included converting the mph fuel cut to an rpm rev-limit fuel cut. I'll dig around and see if I can find it again.

Wrong ecm, but here's what I was thinking of:

The same approach could be applied to the 85 $1F mask if you can find a good source hac.
