Hello sir, help me get a few from you. give me a pm or text 0917 7705282 and I'll invite you a literal Cafe Husky we're working out
Hi Jimbean - my version used a variable potentiometer to give 11 ohms, effectively reducing AIT temperature by approx 16degC My TR is significantly different from stock GPR exhaust, Pod-mod, AIT repositioned, Denso Iridium Plugs, exhaust cavitation plate, quick action throttle, ss oil filter, etc etc What works on my TR might not necessarily work for others If the Husky airfilter had been more effective the need for the Pod-mod would not have arisen The Pod-mod significantly changed the airflow past the AIT, which influences the ECU & fuelling So how do we overcome those challenges?
Can you show a photo that helps explain the lack of airflow past the air temp sensor? If intake air isn't flowing over the air temp sensor, and it was much hotter than the air entering the throttle body, that could lead to altered mixture adaptation values. Resistors in series aren't a good answer for reasons I've described many times already. But relocating the air temp sensor, inside the intake manifold, to an area where in gets full intake airflow is a good idea. Trz_charlie, have you done the pod mod?
Yes, Pod mod has been in place on my bike since 500 miles. My AIT was relocated directly in front (read, nearly touching) of the Pod filter or nearer to the old filter door.
Finally, after much testing l used an 11 ohm resistor soldered into one of the AIT leads, the AIT is now re-positioned to the very front of the motor measuring the ambient air temperature, minus the resistor, the AIT effectively reads a temperature 16-17 degC cooler than ambient Well done for thinking of this
The AIT is located behind the Pod-mod, l was measuring 53degC directly with my thermocouple at the AIT location whilst in traffic, ambient temperature was 30+degsC My AIT is now located in the air inlet, forward of the radiator, less influenced by motor heat I've now done considerable dyno time, 3 test rides in of 200klms each, & another planned for today The bike is running so much better I'll wait & see if the ecu adjusts, the meantime l'm enjoying the ride
Mixture adaptation is a fact and the way these ecus work. However if the pod mod results in the IAT sensor measuring something other than the temperature of the air entering the cylinder, that is bad. Your goal is not that the IAT is accurately measuring ambient temperature, but that it accurately measures the temperature of the air entering the cylinder. If that air is being heated above ambient, then that's what your IAT should indicate. So at idle, in traffic, if the ambient is 20C what temp will your thermocouple measure? Is that what your IAT now indicates to the ecu?
It seems to me the best way to spoof the IAT sensor would be a variable resistor or some way to set the temperature to the actual outside temperature. You would have to set it every time you ride and need a separate thermometer to get the actual temperature each time.
With the AIT positioned as far as possible in front of the radiator it will be reading closer to ambient air temperature Both the Pod-mod & more free-flowing exhausts have changed the characteristics that the ecu was designed for It does appear that the bikes are sold to meet the most stringent of the European & Californian emission regulations ie very lean, our mods tend to make the engines even leaner, to the point of detonation or excessive heat, stalling & stumbling Now, I'm only experimenting, researching & learning more about the systems So far, on my TR, the 11 ohm resistor in series with the re-positioned AIT seems to be giving fairly satisfactory results I've been out on the road regularly & have consumed 30 litres of fuel, over 700klms, I have not noted any degradation of performance Which one could expect as the ecu adjusts/adapts as mentioned in numerous previous posts As soon as I do, I'll run further Dyno tests to compare with previous test results When I first purchased the TR I fitted the Booster Plug to successfully cure the lean-burn & stalling The Pod-mod brought with it more challenges If the Husky had manufactured a better air filter & airbox & mounted the AIT at the front of the bike, then none of these mods would have been necessary
Well I just installed my AF-XIED and did an ECU reset, won't get to ride it till tonight when I go to work. I will report my results, and if I'm happy with it I may have a used Wuka-King for sale soon.
How did you go? The middle of winter in the UK right? What settings did you start with? What other mods do you have? (exhaust, Pod-mod, other ?)
I have the UNI filter on my bike but it's otherwise stock, any effects I had from the Wuka King went away shortly after installing it, still stalling, hesitating and slow to start. I set the AF-XIED to #7 but won't be riding until later tonight.
Has anyone actually put the AIT sensor in the intake tube? To read real AIT and not the air before the filter. Just curious cause its what i plan to do with the pod mod.
Yup, that is the sensible thing to do. The ECU will start adapting immediately. Mine was nearly fully adjusted after about 200 miles or so.
