Anyone have any luck getting fuel pressure to display correctly in Hondata using Analog 0 with AEM 150 psi sender? (or any of the 8 V2 analogs)

I have it wired properly. I can get it to show pressure if I select autometer pressure sender from the presets but the pressure is too low (100 psi vs 150 psi senders).

I tried setting up the custom, selecting pressure and using 0.4 - 0 and 4.4 - 150. These numbers worked when I was using ERLD (D12) but using analog 0 I get a value in the 600 range.

Worst case I have to pick up the autometer sender and pigtail, but since I already have this wired/set up it would be nice to use it.

TIA

 

You are not doing both the setups properly. Any sensor that operates in a 5v range can be used as long as you know the scalar. You have to set up both the sensor tab and parameters - not just one.

 

I did that. I already had it set up on D12 so it should have been straight forward to just switch it to the Analog. Tweak the parameters and the sensor sections. No dice.

 

I'll grab a couple screen captures.

I'm sure I'm missing something stupid simple, but I'm banging my head against the wall at this point.

 

 

By sensor tab I meant the actual settings for the display, I just omitted the word display accidentally. Sorry, about that. So the sensor display tab/menu if you will. Pretty sure you right click and go to properties. If the sensor display properties aren't set up right your datalogs should be wrong too.

For what is worth, all of my Fuel and Oil pressure and KnockSense inputs work just fine. Now that I think about it, are you positive you have it wired up correctly? Sorry, I am telling you all this from memory as I don't have SManager in front of me right now.

 

I'm positive it is wired up properly. I triple checked the wiring and if I select the autometer pressure it displays a pressure value but it is low, 38 ish psi when it should be 43 psi. (makes sense since it is 100 psi sender vs 150 psi)

I also have the display settings set up properly. Look at the gauge display, it only goes to 150 psi despite the output showing 387.9.

This has to be something stupid. I'm at work now, once I get the CPR working tonight I will mess with this more. If I have to switch to the autometer sender I have to switch, was just hoping I wouldn't have too.

Thanks for your help!

 

What are you using for your voltage reference?

Using TPS

 

The pressure units in the parameters even if you hav ethe units set to psi are in Bar. This may be altered in a later release of software, but you can get it to read correctly just by changing your voltage conversion units from psi to bar.

That makes PERFECT sense lol.

Thanks for the help. Now I can get that fixed tonight.

For later info 150 psi is 10.34 bar and 100 psi is 6.89 bar.

 

That worked. Thanks!
