Jetchip installation   Installation of the JET chip was simple and instructions are provided.  Steps are: Disconnect one battery terminal.  The Jet install says positive, the Beretta service manual says negative. Pull out the glove box. Unscrew the panel underneath the glove box. Take the access panel off, it has two screws,  Pull out old MEMCAL chip. Put old chip onto Jet chip. Reinstall. I didn't put the access panel back on, I didn't think there was space. So far it runs ok.  No big boost, but no problems.  Hopefully I will see better results over the next few days as the ECM adjusts and relearns. I DID have to do an idle re-learn after installation, so I assume the chip has to relearn everything, which takes time. The Chip DOES take off the rev limiter but does NOT take off the speed limiter.  For that, I think you need a Superchip.  Considering a fully programmable unit in the future if I can find one.
