E8 with LPG?CNG

Postby TurboCorbeau » Fri Nov 09, 2018 4:16 am

Good day. I am looking to undergo a new project. It will be a 2.0L Turbocharged 4 cylinder, with a dedicated CNG sequential injection system. Everything petrol related will be removed (petrol injectors, fuel pumps, fuel tank, ecu etc) as the car will be CNG only. For this project, I would like to use an E8 I have from another project, however, I am not too certain if it will be able to drive my injectors.

The injector setup on the E8 has peak and hold settings of 2/0.5 3/0.8 5/1.2 Amps. The CNG injectors I am looking at are spec
1.9 Ohms
Peak Current 4 Amps
Hold Current 2 Amps.

I am thinking to use the nearest setting which is 5 Peak 1.2 Hold, but this not an exact match to the injectors. Question is can these injectors work on the E8 ECU? Or will I run into issues?

I know the elite series would be able to handle these injectors without an issue, but would really prefer if I can hold out on an ECU purchase, at least for now.

Thanks in advance.

It wont hold at 2A, so you will have problems with stable injection. Always an issue with gas injectors!
