Good Quality Oil Pressure Sender?

It's a simple matter of inputting the correct offset in the software so that the transducers will be accurate. I've sent him my serial number and software version and the datasheet for the Kavlico transducers that I would be interested in using. Once he reviews the information he will contact me and give me the offset that I need. Anyone else wanting to use the sensors would have to pick the exact sensor they want to use and then contact GRT support. You'll need to supply the exact Kavlico sensor info, your serial number and the software version that your unit has. It all makes a difference.

You positive about this? When I set up my EIS system, I was able to create custom offsets/configs for every sender except the Oil pressure. The EIS did not allow custom config for the oil pressure input. Have no idea why. Possibly they changed it.

I did a kavlico for the fuel pressure. Takes a bit of math, but very doable. I also did a custom setup for the MAP to use a cheaper, GM sensor.

Larry I think you and I simply have different interpretations of what was being asked. I viewed his question to mean did GRT offer to sell the EIS unit with the Kavlico senders. They do not. However I learned from speaking with Eric and as you found out that with the correct offset, the Kavlico senders will work. That's the bottom line that I reported.

I'd like to know more about the offset you used and the part number used regarding the GM MAP sensor.

Just an FYI for those interested in this thread. I spoke to Eric at GRT on the phone yesterday morning. I explained that I was interested in using the Kavlico P4056 sending units. I then emailed him the data sheets for the sending units I was interested in using. He got back to me this afternoon with the scale and offset numbers for these sending units. Information is as follows:

0-100 PSI Sender. Scale. 65. Offset. 23. ( used for fuel injection fuel pressure sender)

0-150 PSI Sender. Scale. 78. Offset. 37. ( used for oil pressure)

Bear in mind that these data points are for my EIS, which has the version V software in it. If your EIS unit has either version S or version J software you're going to have to contact Eric to get the proper information for your unit.

I just wanted to add info about the Dynon TSB regarding Kavlico pressure sending units. See
