Does it take many tries to achieve a desired afr? Also how can i do to achieve afr 13 at closed loop?
    By the way thanks for your info, so far it has been the most usefull!

    Closed loop areas need to be tuned to 14.7, and this can be done with the narrowband o2 sensor. Open loop areas can be tuned to whatever (13.0, 12.8, etc etc) but you need a way to measure the AFR (since narrowbands are only accurate at or near stoich).

    I have wbcx installed so i can measure open loop areas.
    But what if i want to run closed loop area to 13 afr? Is there a way? If not, can i run the whole map in open loop in order to achieve afr 13?

    Aracer comes with an ECU purposed for performance and parameter specific for said reason so it is much faster and accurate at achieving those goals.

    Dynojet and all this other shit just Flash/Piggyback a Stock ECU meant for reliability and environmental regulations.

    Which sucks cause I own all this with decsent knowledge and success of how to tune with these, but still thinking Aracer...

    Yeah, I get that. The Grom is a pretty simple bike from a technology perspective, so replacing the ECU with a "standalone" isn't a bad option. There aren't multiple other modules on the vehicle data-bus that would throw a fit if there was a non-OEM/ non-integrated ECU in play like other bikes / cars. One of the virtues of a Power Commander V and most other piggyback systems, and even standalone ECU's is the ability to do RTT (real time tuning).....to the extent of whatever they're designed to control. Reflashing the OEM controller / ECU is a nice option for some people since it's easy......plug in and flash.......but if you need to dig in and start tuning, yes, there is a STEEP learning curve. Those that have ECU editing / flash tuning experience pick it up quicker, but most with that sort of experience come from the "car world".

    Right on the money. There's a lot of stuff in the OEM that ultimately makes it more difficult to achieve the desired result. A replacement ECU designed to run an engine without the need to support systems needed for compliance is pretty straight forward / not a lot of "stuff" to get in your way from a tuning perspective. If you chose to work with the stock ECU, you just need to find a competent tuner familiar with the best tools for the job........or be willing to dive in an learn.

    OK, cool you have a WBCX.......I thought you did, but couldn't find the post to verify. You can NOT target 13.0 AFR in closed loop, that's not how things work. Yes you can force OL fuel control and tune it to whatever AFR you want. Personally I would advise that you "tighten up" the CL range and then where needed (higher RPM and load) enter performance enrichment by way of OL fuel control

    There is a video showing you how to enter OL fuel control somewhere on YouTube. Also, perhaps my CL-OL guide would show you how......I can't even remember.

    100% agree with you. I have not givin up yet, In my local area only one MC Dynojet Dyno and they dont know shit about groms or PV3 lol

    And the other Dynojet Tuner that does know his shit is 1hr and 15mins from me,,, He favors Pcv setups to tune and said he would have to dig into the PV3 software and get familiarize. For what he wants to charge and his lack of desire to learn pv3...

    No thank you Im not going to pay him to learn it, I would be better off going Aracer and get the learning curve over with just like I did when I purchased all DJ products

    BUT NOT YET

    Do you think the slower processing speed is a limiting factor? Is the ECU doing something to affect your fueling or timing that you did not intend?

    Now i have CL up to 5000rpm and OL from there to 10500rpm.
    The problem is i try to set OL with the script and tunelab and afr are not consistent to what i set it to...
    Maybe needs many tries with tunelab till its consistent?
    With this i mean that is not one time setting tunelab with logs and takes lots of times modifying the map with tunelab, flashing the corrected map, take logs and start all over again and again untill the map shows the exact afr i want... Is that correct?

    I have full DHM set up, he is familiar with Pv3 and of course his own Flashing capability.

    Ive asked David why doesnt he offer a tune for his setups flashed to stock Ecu, he said that very thing stock Ecu is not fast enough and limited to keep up with these type of mod setups,,, He himself prefers Aracer

    No un-intended effects from Ecu for fueling or timing but its also not perfect, I honestly feel like my setup has more to give than the ECU will allow, unless I bite the bullet and take to dyno...
