Well EI customer service is great but you pay for it. Never once did they offer to send a replacement part under any warranty. I have sent items to them to be “overhauled” over night FedEx like they said to do only to have it sit on the shelf in the shipping room for a week before they even got to it. Never any sense of urgency on their part or “lets see if we can find a solution” just send it in and we will look at it then all they tell you 10 days later is we overhauled it, they dont tell you what was wrong with the component or if it will happen again, It’s never their fault. My brother is on his 3rd manifold pressure transducer/box (Sorry, I forgot the exact name for the component) and it has failed. His airplane has about 300 hours total time on it, the last one failed on his second flight a few days ago, thats not right. I hope its a simple fix in my brothers case, its possible but with our luck I doubt it. So if your units are working and you haven't had any problems with them that is great, they really are fantastic units when working properly but for my brother, other friends and myself we have all had issues. I really don't mean to bash EI but these are my honest experiences with them and their products. I dont have any actual experience with JPI but I have heard of issues and problems with their products and customer service. So who does that leave? Garmin? I dont know. I will say, the EI tech’s Dave and Dave are very nice on the phone and they will talk you thru any operational issues you may have. One thing I would suggest, before doing the actual install inspect the wiring harness plugs closely, that is one area I have had issues. Without digging out all my receipts I estimate I’m over $5,000 parts and labor in dealing with my MVP-50 issues.
