Thanks, just could not find that info anywhere in any documentation hence the question. All good !

On the subject of the expansion connector regarding the signal ground. All my temp and pressure sensor grounds come through here but how about frequency based sensor ground ? can that also come through here (interference distortion) Just making a turbo speed input using Richard's example from another post, thanks again Richard :-) Help always appreciated!!

Thanks for the tip Richard.

Most other ECU makers advertise a max mA output. I did find the Thunder has 5volt max 200mA supply. How about this one ...anyone?

What would be the maximum current rating for the 5v sensor supply on the expansion connector. Cannot find it anywhere, currently has 4 sensors on it consuming max 13mA and want to add another max 10mA Thanks in advance!

Thanks CamB

I know its an old thread but I am just in the process of fitting an EFR speed sensor and was reading Richards original post regarding the 4018IC. In Richard's explanation he has the Clock (pin 14 of the IC) as the input and not D (pin 1) as suggested here. Just making one up and any help for an electronic newbie much appreciated.

Fantastic Scott, thank you for that. Mike

Hi Adam, Yes it has x%FF, maybe x % full flow not sure. If I use open loop the table, X is Inj Duty Cycle% and cannot be changed. It is a mystery , well to me anyway. No doubt there is a very simple answer! Its not something I want to experiment with and must work correctly from the onset. I now have a Pierburg intank screw pump to replace my old intank supply and external Bosch 044/surge tank. The original 3 stage FPCM (r33gtr) would be great but it would not be durable and will fail with the increased load. Just need to run the new PWM FPC the same way really without getting too elaborate.

Hi Scott, regarding setting up the speed control, I will just use the 80Hz 33/66/100 D.C to keep it simple. The PWM controller needs 100HZ which I can change in Aux outputs # FP Speed, however the controller D.C is regulated by the Inj. D.C . How do I set this up when running a modelled fuel equation where I have no visible Inj. D.C? Appreciate your help Mike

Hi Scott, Thanks, that makes it much clearer! Yes I have fuel press & temp sensors so will look into the closed loop. Advice once again much appreciated. Mike

Hi all just hoping someone can clarify this for me please. The Fuel pump control setting in Aux outputs using the 2D Open Loop Table which has an X axis of Injector D.C % only. I am using the modelled fuel equation and my question is how can I relate the VE number in the #1 3D fuel table to the Injector D.C% number in the FP 2D open loop table? If I was running traditional msec then its easy however I'm baffled by this one sorry. As always really appreciate this forum!

Hi Scott, The 20 pole connector for the SDM300 dash or the SDM pins are dodgy so have to chase up Plex for a fix on this one. Thanks for your help Cheers Mike

Thanks Scott, Will do. Cheers Mike
