Great product I had questions about their engine protection products so I called and spoke to one of their staff. I found him to be very helpful and well informed. Excellent depth of knowledge which provided me what I needed to make the correct choice for my application. Product arrived in a well packaged box. I'm impressed with the quality of the device. I also like that it's made in the USA. Higher cost than some other alternatives but I'm not willing to take chances with my expensive equipment. I can not afford to take any chance of damage from overheating or loss of oil pressure.

Very knowledgeable Very knowledgeable, helpful, and got parts out door same day. I often spend that long getting a hold of the tech who really knows what I need :-) I'm sure this is part of the reason caterpillar sent me to them to solve my custom control application.

My lucky day My lucky day, David Ortiz picked you my call and solve my problem in 5 minutes, nobody knows more than David when it comes to Diesel engine controls and emergency shut downs. Thank you David

Timely Service Quick shipping and great support trying to replace two 25 year old engine control panels now obsolete w/ new units on critical water diversion pumps.

Great service on a special request The usual story, trying to get wheat combined in Montana and the fuel shut off solenoid on the diesel engine decided otherwise. Found the piece on MurCal, put in the order, asked them for special arrangements on shipping which they took care of right away and the part was shipped out as requested. Doesn't get any better than that. Now if FedEx had done what they were paid to do... but that is another story. The folks at MurCal did a great job. Thank You!
