I’ll have to look at mine and see if it think the ac is on or something and if that would cause it to idle higher. I don’t have ac so I can just disable all that.

I changed my idle target RPM to 1050 at 140f, 1050 at 176 and 1000 at 212. This is nicer when sitting, but the decel still effects it when rolling to a stop with the clutch in. I'm going to play with it more this afternoon, but it looks like you can set Decel Min RPM as well which I'll try 1100 or so at 140f and 1050 176f. If it acts funky I'll tweak further. |

Thought I’d share where my fuel gauge was and how much gas it took today. Gauge was at about 5/8 and the car took 6.07 gallons. And I had driven 86 miles. So I’m still only getting barely 14mpg. I probably need to just work on the tune a bit at cruising rpm/load to get better mpg.

I think the only difference possibly between our mileage is injectors and I may be running considerably more highway? I deactivated decel on the Haltech and now my low RPM jerkyness is gone. Gotta figure out what settings I need to adjust but at least for now it’s better around town. |

Just so I understand the process:
Haltech/KP supplied a base map/maps, which consisted of a volumetric efficiency (VE) map and a target AFR map, right? I really haven't gotten into the software side too much. I am just trying to understand it. An AFR map should be based on rpms and MAP. The AFR map, as well as, the VE map are just conservative maps. A tuner would need to modify the AFR map and VE map based on the vehicle specifications. Maybe a turbocharged car will want to be a little richer than a NA car to avoid knock or something. Besides that, a tuner will modify ignition timing and cam timing to gain more power, right? The short-term fuel trims adjust the fueling to hit the AFR targets, and the long-term fuel trims applies its corrections to the VE maps, which means the short-term fuel trims should make smaller and smaller adjustments, right? Basically with self-learning, the long-term trims are applied to the VE maps, right? If the AFR maps are conservative then self-learning will get the car closer to those values, but not necessarily optimize the car, or will it? Will self-learning modify the ignition timing or cams to optimize the power? No, right, because it doesn't know the power, but only AFR targets, right? Sorry, I'm just trying to understand what self-learning does because I watched the Haltech video, and it didn't really answer my question.

Unless you're really that concerned about range, your opposition to getting free power makes no sense... BTW, I made a flex fuel system for mine including the tune for less than $250... Jaden |

@Jaden where are you even pulling these posts from that your quoting? Page 1?
Ok I went and looked. Page 10. Glad your reading the thread, but don’t see the point in quoting something from 38 pages and 10 months ago. Kinda like the guy that came in yesterday in the middle of our talk about how our gas gauges aren’t working correctly and he posted just to say our gauges aren’t working correctly. |

I am only applying the learned long term values. There is an option that will add/decrease timing based on knock detection. I’d say the base map is pretty good, I don’t see a reason for me to ever get tuned. I will continue to tweak it myself, it drives good as is and i have no issues going to redline everyday. The supplied map is based on a k24a2 with 50° vtc gear, kpower intake and header. Since they are only about 5 hours from me, around the same altitude and temperatures, the map works great for me. |

As for my drive, I’m pretty much never on the highway, and when I do get on the highway it’s only for 5 miles. My actual drive to work consists of 1.9 miles doing 35mph. But when I do actually drive the car away from town it’s usually to beat on it on back roads. I never got great mileage with the FA20 so it doesn’t surprise me that I’m getting horrible mileage now. Once it warms up I’ll start messing with the tune again and see if I can get better mpg. |

https://www.ft86club.com/forums/show...&postcount=192 ---------------------------------------------------------------- On a separate note: did you guys update the ESP to NSP? Is the base map in ESP and needs to be uploaded there before converting to NSP or will the NSP software read any tune or convert it, which means I can upgrade to NSP first?

I haven't been on the site regularly for a while so I'm catching up...

Jaden p.s. hey but you guys have come a long way from when I mentioned that Haltech was claiming that they had can for the 86 platform and no one believed it though...Oh and very shortly I'll have some fun stuff to post... |

I’m sure the tune can definitely be optimized for each car and make more power. Fuel and altitude can really effect the tune, and those two are different everywhere. |
