AZ greddy boost sensor

can you use a greddy boost sensor for the E8 instead of buying a 3 bar boost sensor from haltech?

Possibly. You would need to know the output characteristics of the sensor and program the ECU to suit.

Hey, i was playing with this and i came across an issue with the Load Axis disappearing on you when you input the values for a custom sensor.

The fix is to input the values with the software in metric units, this means getting KPa units for the sensor you have, otherwise the Load axis on most of the 2D maps disappears on you (see pic), after you've input the values in KPa then you can revert to Imperial units and the Load Axis will display correctly. This issue was also present in v1.71.

Here are the calibrations for the Greddy 4bar MAP sensor both in PSI and KPa.

I told you to loose that usb adaptor allready!
This might help you with that problem----> https://www.rx7club.com/haltech-forum-62/reasons-weird-behaviour-your-e8-e11-firmware-update-issues-790256/
Seriously I have not had that problem with the latest revision on any of the applictions that I've done as of late especially since they all got custom map sensors and calibrations also.
