PC5 witch Autotune - Closed loop area
Hi everybody!
Let me shortly introduce myself! My name is Thomas, I am from Germany an drive a XT660 X 08. I am driving the XT for about one year now and I' ve done the following mods: PC5 with Dynojet O2 Optimizer DNA Stage 1 air filter NGK Iridium GPR Furore Cans wiht CAT and silencers ( http://www.gpr-germany.de/artikel/gp...f-mit-kat.aspx) As I did not find a suitable map, I've loaded this one from the PC website to my bike: 412-515 (European model Akrapovice SP Series open slips on DNA Stage 2 air filter kit Now I want to use Autotune. The PC website says: ( http://www.powercommander.com/downlo...I22-020.03.pdf) "The O2 Optimizer for this model controls the stock closed loop area. This area is represented by the highlighted cells shown in Figure L. The Optimizer is designed to achieve a target AFR of 13.6:1. To use this O2 Optimizer you must retain your stock O2 sensor (even if using Auto-tune). It is not recommended to alter the values in the highlighted area of your Fuel tables unless instructed to do so by a Dynojet technician." Can someboday explain that to me? Or just simply make statement, if I should follow Dynojets advise or not? Has somebody a good advise for a propper AFR table? Kind regards from Germany Thomas |

The map you loaded is likely a bit off since DNA 2 provides the bike with alot more air than DNA 1 unless you have a drilled airbox. Same for the open akrapovic, they dont have as much exhaust resistance as your option. If you are going to use autotune i suggest that you start off with either a DNA map which you can get by contacted DNA support or the standard map provided by Dynojet and then build your map from there. The closed loop is controlled by the ecu, the provided optimizer from Dynojet is just a way to try and optimize the closed loop afr. If you want to get full control over the closed loop and let your commander map the the entire revrange to then i suggest you contact Kev on this forum since he has O2 eliminators for sale.

Hi Flaggi,
thanks to your answer!! Which map do you think would be a better starting point? M22-020-502 (European model Stock Exhaust Stock Air Filter Airbox snorkel removed Dynojet O2 Optimizer installed or M412-520 (2005-2007 Yamaha XT660R European model Leo Vinci open slip ons Stock or aftermarket air filter) "The Optimizer is designed to achieve a target AFR of 13.6:1." And if I do not want to buy another O2 Optimizer, what do fill in the Cloosed Loop Area when keeping my Dynojet O2 Optimizer, Zero's or just 13,6? PS: Just talked with DNA support, they said, they have no PowerCommander Maps. Kind regards Thomas Last edited by tom2139; 08-08-18 at 09:15. |

Today I've tested the following map:
M22-020-502 (European model Stock Exhaust Stock Air Filter Airbox snorkel removed Dynojet O2 Optimizer installed It has already a AFR table inside: https://picload.org/view/dlolador/af...d_map.png.html The following trim values showed up after some driving: https://picload.org/view/dloladoi/totrim_new.png.html Based on the  Dynojet AFR table and some internet articles, I've created the following AFR table, what do you think about this one?

DNA does have maps, not for all bikes but i have bought DNA stage 2 for two different bikes and in the papers for both of them they write that you can contact them to get maps for your setup.
However it doesnt matter when you go with autotune since you will build your own anyway. You can use any of the two suggested maps to start with, they will get corrected if properly autotuned. I did look at your suggested table and to me it seems too lean in many fields, could it be that you have been cruising around doing normal driving with autotune? To get proper values you need to record under load (I did this fault when i started using autotune and it will throw incorrect values. Skickat fr�n min ONEPLUS A5010 via Tapatalk |

=> What do you mean exactl? Whenever I was able to accelerate full, I did ;-) DNA just sent me maps, but all are for Stage 2... This PC5, Autotune, Map topic is a mystery to me... The map for DNA Stage 2 and open Akra was much more powerful, even after modifying with Autotune, the Standard Map was much less powerless after modifying it with Autotune. Kind regards Thomas |

I used to run autotune the way i think you are doing (trying to keep the bike under as much load as i could and always letting it read the values). This gave poor results and ended up in me removing it and going back to a premade map. Then Kev. suggested a killswitch for autotune to make it easy to only flip it on during load and flip it off as soon as the throttle is closed. There was a huge difference for me and now i have really good maps for both my bikes. Skickat fr�n min ONEPLUS A5010 via Tapatalk |
