Actisense EMU-1 Engine converter analog to Digital

[Chris L]

Thank you @Skybolt, that was indeed the problem. Once I set that correctly, it showed up.

Now I have two issues to address. The boat has Teleflex gauges on her (CAT 3116's) and none of the existing profiles match well with these Teleflex units.(oil pressure and coolant temp) I am trying to decipher the Custom Gauge Manager, but I am unsure what the easiest way to read the current voltage from the gauge is. Please let me know if you are aware of that. Secondly, the Garmin 1242xsv units seem to only displayed RPM's in 50 RPM increments. I would prefer to be more precise. I believe this to be a limitation of the Garmin, as the NMEA Reader shows the exact measured RPM. I am curious if you have any thoughts on that.

Im debating on the EMU1 and have teleflex/3116 gauges also. I'm sure somebody had added those gauges via the custom gauge manager and should be able to export/share the mapping..

@TheBobC - You may want to ditch the current senders and use new ones that are know to work well with the EMU-1. The custom gauge manager works well also, but it doesn't work like they say it does. You can enter the manufacturers resistance curve in there even though it states voltage. I tried voltage and noticed nothing would work, tried the resistance curve and it worked like a charm. Although their tech support will argue that yo need to enter voltage.

Either way, it does work really well. On my 1243's there is a setting to not round the RPM's and I use that. I am not sure about the 1242. I also don't remember where that setting is, I am going to the boat this weekend and will take a look.

I don't know many on here that actually use the EMU-1. The type of gauge doesn't matter, only the sender does. As mentioned above, I would just get ne senders that work with the EMU-1. I am using VDO senders.

Great.. That said, how does one ascertain whether new (VDO) senders are compatible with the existing teleflex gauges, or does one have to change gauges to match senders?

Isn't the purpose of getting the EMU-1 to get rid of the gauges and go all digital? Other wise why bother. You don't need gauges to se the EMU-1, in fact it works better if you don't.

 

[TheBobC]

For now I actually want both. But your ideas are an interesting idea.

It is, but I've seen and worked on enough failed digital gauges in cars that I don't fully trust all digital. Why not keep the analog gauges as backup...

For anyone else looking at this part, I spoke with Garmin support. Go to the engines page/settings or options/installation - RPM Rounding. I am looking forward to getting back to the boat tomorrow to verify this.

As to the sender and custom gauge manager, is there anywhere that shows current voltage foing in to the Actisense? Also, the "resistance curve" you mentioned...did you get this from the manufacturer?

I started reading a month ago. I actually ordered an RS11 first, but wanted the better accuracy of the EMU-1. I installed it last weekend and once I took Skybolt's direction on the NGX settings, it fired right up. I will update here as I go, and will be happy to share the teleflex profile with you once I figure mine out. The tach, which was my original motivator, seems to be right on. It is 134 teeth (PPR) by the way.

As I stated. The rounding can be turned off, it works just fine. My whole system was calibrated on my desk before I installed it. Actisense states to enter voltage, but that doesn't work. I entered the resistance curve and it worked perfectly. Earlier in this thread I show my calibration method.

You will need to email Actisense. "foning" won't work so well. Their in the UK, tough to connect.

All moving parts fail at some point. Digital doesn't move and if taken care of, should last a very long time. The best part of this is if the digital fails, the engine still runs. My engines have a complete set of gauges mounted on the engine, so there is backup if needed.

Thought I would post the custom gauge files for my original Oil pressure and Temperature senders used in this thread. The part numbers for the senders are in the file names.
