Woohoo making progress finally on this front! Took a base tune that was running pretty rich. Tried to get a road tune that I could run this weekend Stabilize power areas around 12.5 afr and 12.0 closer to change over and right at rev limiter. Have a 4k vtec change over and minimal timing changes at this point.

I same to be getting random "quirks" with the software, but overall relatively decent for what I am trying to do. MY hope is fine tune a bit more and get to a dyno. Plan to target 12.9 afr where it counts and get some timing adjustments.


Questions:
-How are you guys tuning ignition? Are you using MTBT method? Are you attempting to trust factory knock sensor and tuning for a certain number of pings? If so what settings for knock do you have on the emanage?

Has anyone found a way like hondata to make mass changes to a section of the map? i.e. highlight and +.5 to duty cycle?

Well done.

At low revs, you can hardly see the knock sensor registering any knock, but you will 100% see the ignition timing being pulled back by 3-4 degrees in a fraction of a second for no apparent reason. Then you know that you need to pull back timming a bit at these rev. Std knock sensor is more sensitive at low revs and lazier higher up.

Since you have vtec lower at 4000 you need to advance ignition by 7-10 degrees in the 4-6 range.

Page up and page down buttons on your keyboard increase or decrease all the highlighted cells.

For me Emanage is almost as good as a standalone ecu if you know what your are doing and most importantly read the logs very carefully.

Let us know how you progress.

I could use some help with an emanage ultimate install for an AP1. I just got it installed a couple days ago and my tuner reported a small intermittent problem of a low rev limit ~ 7K on the dyno. He said it wasn't a big deal and should go away if I unhooked the battery to reset the ECU. I drove the car home and it would only give me a problem if I downshifted after cruising for a while and tried to get up in the rev range. I did the whole unhook the battery thing, and then the car would not rev beyond 7K. The car was cycled on and off a couple times from driving and now I got my rev range back to 9K with tune intact. On occasion the lower rev cutoff creeps back, but the tune is still there on the low range. Any thoughts of what is going on with this thing? I feel like the stock ECU is trumping something weird and goes into a safe mode.

One more observation, I can now only get two bars on the temp gauge after the tune. Before, normal operating was three bars.

I have played briefly with ignition but without a dyno a little nervous are others adjusting ignition this much in 4-6k? what about above 6-9k this? Iwould love to see the timing advancement people are successfully doing on an ap1, feel free to pm if you don't want it in here.

Without a lot of ignition change i am getting 12.6-12.9afr consistently with various load, if i advance should i ever need to add fuel or just follow mbt or the like and stop tuning?

If your temp gauge is low then the ecu will limit revs. Not sure how Emanage handles this but on my haltech yiu can set Rev limit by temp range. You also have to have the coolant temp sensor calibrated so if your ecu is not seeing the right Temps it may be limiting revs

Finally read the entire thread ... !!!

Sorry it felt like a victory and needed to share.

Lol

Thanks for all that put the effort into it.

Now my turn ....

Maybe this is a dumb question (in which case I apologize for the thread necromancy), but it seems that the only reason we can't run a K-Pro on 00-05 cars is because the K-Pro and AP2v2 ECUs are expecting a hall-effect sensor for the TDC and crankshaft position inputs, while the AP1/AP2v1 is equipped with variable reluctance sensors. Given that section 14.10 clause F.3 specifically allows inline components to alter signals between the sensors and the ECU why not simply convert a VR sensor to a hall-effect square wave using something like an LM1815 (or a premade board like this) and then stuff the K-Pro into an S2000 ECU enclosure?

My STR build is still in its infancy, but when I finally get around to ECU tuning, this seems like a much better option than mucking about with piggyback systems.

A bunch of us are. Some his remote tunes and some of us are dyno'd by him using the Emanage.
