I've been away from building for about a year or so and finally received news I can keep the car yesterday, so back to building.

My question is on the AEM FS gauge.. Can it be used with another system like Neptune as opposed to the AEM EMS? I didn't see a really difinitive answer on their page or their forum. Just curious because I have a lot of work to do and being stationed overseas means good tuning can be hard to find.., except in Japan.., but I'm not there

 

If it has a grounded output you can run it to a grounded input and activate any feature that accepts an input for activation.

 

Hmm... I just looked at the page again, didn't see any mention of it. I'll do some more looking on it. I've got Neptune in my prelude but never got to play with it because I got stationed over here. Had crome but leaned out on top and my motor told me to go eff myself. That's why I'm interested in the FS gauge. Doing a rebuild and more work and don't want to risk another lean-out.

 

You can use the clutch based 2-step to create a safety limiter, outputs to do any number of things including alter fuel and timing, switch maps etc.

 

I appreciate the help. I'm with it, but the problem is I have zero tuning experience and the local shops are nothing more than mechanics. I have to take it to essentially a regional shop who specializes in performance builds. They run mostly european cars and one or two eg hatches, so i have to do as much of the work myself as i can. I want to learn and I want to use Neptune, but I've got to make sure it runs and doesn't blow while I'm learning (minus user error, of course). The guy who I was supposed to learn tuning from on my prelude was killed so now I'm stuck like chuck.. Best I have is a guy who can help me with crome.

But if I can use that option on NT then I wouldn't need the AEM FS gauge at all.. The plan was to install NT when I was doing my original build but the car wasn't going to be old enough to bring back at the end of my tour so I just played around with it on crome. Now that they extended me and I can bring it back, I'm working on refreshing my memory and starting a new build plan.

Thanks again!

 

The failsafe will have a AFR high and low limit for Boost vs RPM anything outside of that range for the specified time will trigger the failsafe. The failsafe will send a low side ground output.

 

Don't be afraid to learn to tune yourself. Everyone has to start somewhere. I got Neptune a few years ago and have been playing with it since. At first it was a little intimidating, but after playing with the software and reading ALOT. I'm able to navigate through 99% of it without issues. There's a section in the software (help section I believe) that explains pretty much every setting and option. Its pretty user friendly and there's plenty of basemap combinations to get you started. All you really need is a wideband and a decent laptop.
Its not that hard at all. Just get your AF ratios right and be conservative on the ignition timing. Fine tuning should be done on a dyno. In the meantime after you get a good baseman calibration, you can play with all the other functions designed in the software. Cold rev limits, hot rev limits, launch control, anti theft, switching maps based on whatever input you choose,etc.
Go for it and have fun!
Happy veterans day Btw. Thanks for serving!
