Several weeks back, I drove to a resteraunt about an hour a way. Had a leasure lunch with my wife for maybe an hour and a half. It 93 degrees and full sun. When I came out, the first time ever the car wouldn't start. It took multiple times cranking for more than a minute each. I was afraid or melting the starter or killing the battery. Finally, it fired and ran like junk for 15 seconds and than all was well.

I ordered Daves RPM relay along with his Hot start relay. (Plug and play)

Yesterday, I went to the same restaurant with my wife under the exact same conditions. When I came out, the car started right up and ran rough for maybe 3 seconds before running great. His RPM relay has an additional feature called a hot fix. I don't have that enabled right now, but under the current circumstances I don't think I need it.

My old RPM relay use to get real hot. I forgot to feel his after the trip, but I will up date this in the future. (It's supposed to run cooler)

I don't know that Dave is really trying to make business of this. I think he just does it in his spare time. I highly recommend buying any of his products because he just might decide to stop. We are very lucky to have this man in our community.
