That's the worst afr targets I've seen....Your AFT + Narrow band = Fail at life
|
I'm getting around 19mpg too. I just haven't leaned it out yet since I'm not confident about the base timing map.
|
HOLY SHIT those afr targets are fucked up
|
The target table behaves completely different when used with a narrowband sensor. I've got mine to go to open loop above 85 kPa, and anything that isn't set to a target of 14.7 is ignored by the Adaptronic.
I've already had all the cells tuned on a stead state dyno so I think having a wideband O2 sensor is bordering on useless now, unless I want to target a 15:1 cruise or something. If I was plugging in an wideband O2 sensor into the Adaptronic then yes it would be fail city. This is what I came up with on my old car (LC-1 equipped) which gave good economy: http://sites.google.com/site/timkent...fr-targets.png It's not really relevant for this setup, as discussed above re narrowband sensor. |
What are your startup enrichments? My mpg went up as I've adjusted mine.
I still only get ~20mpg unless I baby it, but I'm almost always in boost at ~75+ mph with lots of hills. |
I know - get rid of that POS and get another SE!
Plenty for sale atm. Stu |
Here's a link to a datalog from tonight:
http://sites.google.com/site/timkent/5-03-2010_2104.csv It appears that the narrowband O2 is hovering around stoich at cruise like it should. |
|
Damn, that's a lot of AFR target points, nice.
|
I know I'm jealous.

You guys are silly with your low resolution maps

hehe
Thats actually Crome, which is FREE! You can re-chip the factory ECU, burn a Crome tune onto the chip, and you have the resolution of a standalone AEM and it only cost you 30 bucks. Now why couldnt mazda have made their ECUs so capable? :facepalm: |

yes your map is very high resolution. what the fuck is a millbar and does thsi "hondata" make miata stuff? :P
We wire up after market ecu's, why couldn't we use a honda ecu? They can be reprogrammed so it shouldn't matter as long as the cylinder count is the same. Or does honda use some wierd cam/crank signal? Then we could have powered by honda stickers too! |

It has inches/psi of vac/boost on the row below millibar :loser:

You could make a honda ECU wok on a miata, but you would have to mount the honda distributor on the front of a cam gear.
It has to go on the front of the cam because honda engines spin backwards, and they have the distributor on the back of the cam. I actually thought about doing, but it would probably prove to be pretty difficult. |

Actually in Japan, they did. Japanese miatas used an ecu that had a separate ROM chip on it. You could change the fuel/timing curves, injector size, etc. For whatever reason, when they brought these cars to America, they integrated the ROM into the CPU and noone to my knowledge has come up with a way to break it out into something flashable.

Why cant we get these ECUs? and do you know if there is already software developed to write a tune to them?

The company is called GRID Japan. Some info: ROMチューニング用追加基板の取付 ROM???? (all in japanese :vash:) And the jackpot: Japanese Performance Parts and ROM Tuning GRID Not even sure if they still make the miata version. |
