air temp sensor relocation

for all you fellow mechanics i want a little input on a wiring harness alteration. i currently own a 98 vfr800. the 98 and 99 models dont use o2 sensors for timing and fuel adjustments and rely on the air intake sensor, throttle position sensor, and map sensor to make fuel and timing adjustments.
heres my plan. splicing into the air temp intake sensors harness and buying another air intake sensor and relocating it away and isolating it away from engine heat in a different location. theoretically allowing me 2 retain the factory setup for economy everyday useage purpose and switching to the hidden relocated sensor to fool the ECU into thinking the engine is still cool (cold) and reverting the timing back to warm up mode. being able to utilize the relocated air temp sensor at the track with pump premium or race fuel is my intention.
wiring both sensors into the harness isnt an issue and can also be switch via relay and remote hidden switch to retain stock look.
ive already purchased and installed the PC5 and self tuning box and o2 sensor and bike runs great. better then it ever did!! but before i try this modification with the air temp sensor i want a little mechanics input and were else would i get it besides my brother and the mechanics here on this sight. theoretically it should work since the air intake sensor is the main sensor of the 3 sensors the ECU will rely on for input to make the timing adjustments and start leaning the fuel out and back the timing off after its warm.
ive got to order my speedhealer yet and install that since ive just changed both sprockets minus up front and plus in back and installed new chain.
unfortunitely i wasnt able to dyno run it yet but the PC5 i installed 1st and it definitely woke the bike up. the gear swap i havent been able to test the bike yet since im waiting on my redline synthetic oil and filter. i just installed kevlar barnett complete kit with stronger springs to have more clamping force since im running synthetic oil.

 

Wow, you sure you bought the right bike? Lol seems like a cbr 1000rr would better suit you. Im not an expert on the computer ecu stuff. But i have had a lot of experience with jetting carbs. The only benefit you could get from adding more fuel to the mix is to also add more air as well. So i could be wrong but it just seems if you dont open up the airbox or exhaust to compensate for the extra fuel you would actually be losing power by making it run to rich. I forget what the optimum fuel to air ratio is (maybe 14 to 1) but i know if your to far off of that you will actually be losing power. Like i said i could be wrong. I always thought those power commander things did all that for you orgave you that ability to to change how much fuel you got at certain rpms by being able to program new maps into the bike? Either way sounds very ambitious good luck.

 

theoetically all motors with race fuel and an ignition system advanced to help accomodate the higher octane fuel will produce more power. and we know or should know the vfr800 motor with 11.6.1 compression ratio has the potential to make more power with tweeks here and there. thats why most everybody here on the forum removes a piece here installs a piece there. theres nothing wrong with modifying ones ride to squeeze that last drop of power out of it.
actually im a ford dealership mechanic and do possess the skill to do the work on my own. i have done somthing similar to a GTP pontiac when installing the cold air intake system on it. the kit from summit racing required the air intake sensor to be installed near the fender farther away from the motor.
just because honda hasn't supplied a kit or the aftermarket dosent meen it cant be done or beneficial on a smaller scale on the bike on power increases. gotta think outside the box at times.

 

as far as the airbox goes i acquired the airbox assembly used for the supercharger app for the bike on ebay. the seller was parting the bike out and the supercharger itself was destroyed in the accident. just using the airbox top and hose kit with it and improvising a little bit and purchasing few elbows from summit racing i can mock up and install a fresh air intake setup out of it. just the cooler denser air the motor will draw from being
mounted away from the motor will be beneficial.

i have had a passion for viffers since my 1st one back in 86

 

Interesting concept. I was working at a machine shop years ago when bmw paid the movies to feature their bike in the James Bond movie of the time (lot of crap being hocked in that flick, Omega Watches come to mind.) That bike was an FI unit, well, one of the owners of the shop was fabbing up a custome exhaust system, his approach was to weld in a bung and place the lambda sensor there. My memory serves me, he did this just by the way the bike rode and smelled, (plugs.) I really dont remember how the project turned out because I took another job.

I think you could make it work. It would be essentially working on closed loope if I am not mistaken...I had some drivabilty issues with one vehicle and ended up replacing the IAC, TPS, did not do the MAP, as I had some cleaner handy. Vehicle already had a new 02 sensor...Thats why I like carburetors on motorcycles, but bmw made me appreciate FI on bikes though...least on their air/hex heads...Goood luck and post some pictures :smile:

 

after this winter i plan on taking it to the dyno and having them run it just to get a figure were im at. hoping he will let me run it 1st for a baseline with the PC5 disconected in stock form, then run again with PC5 hooked up and then once again with the air intake sensor switched to the relocated sensor without charging me $325 a pop. dyno time is kinda spendy here.
this will definitely put dynotunes auto tune to the test and see if he will need to optimize my bike any with a custom map or wether the wide-band unit does the job as dynotune says it will.
but im very pleased with the way the bikes running right now with the PC5 and auto tune. it made a world of difference as if i had been to the dyno and had them put a custom tune in.

 

one bad thing tho is i will not get to run it on the dyno before i freshen the valve seats up and do a bowl blend and minor port work. i have access to the machine shop here next door at my work and get a very good discount since the owner used to work with me here at ford. but i do plan on flowbenching the heads before and during the headwork since doing that type of work only costs me my time. well maybe a little bit of epoxy and a few 12 packs lol
so basically my 1st dyno pull may be higher then normal from the port work.
wished we had a dyno close by were i live and wasnt $325 a pop. i do plan on getting a final finished project dyno pull to at least see what the changes i made and will be making yield.
more then likely the bikes going to yield CBR1000 HP figures when all said and done.
but i wont be dissapointed if it dont either way.

 

yea 325 is the cost for custom map. not sure if he will go lower just to put it up and run it for just a HP reading. and yea theres only 2 dynos capable of running a bike near were i live. mainly they deal with the harley crowd and i guess if a person owns a harley and theyre bringing em in they must figure we all have deep pockets lol unfortunitely i live in the wild west hear near sturgiss. shit they charge you for the water here!!! lol
