from GSXR's info i ended up soldering 3 resistors in series, One 100k plus two 1M = approx 82k total. doing this brought the vent temps from over 50 degrees down to 40-42 degrees, major improvement
as he suggested I used 1/2 watt resistors from Radio Shack, bought a pack of 1M and 100k. A dollar each, i had 2 sensors so i modifed one at 91k and another at 82k, 91k was too conservative and compressor would still cycle to soon, 82k was better, thinking of trying it with one additional 1M and see where it goes. i think we all need to do this, also this may help those who get the poor cooling after R134A conversion One 100k plus one 1M = approx 91k total One 100k plus two 1M = approx 82k total Quote and picture from his info below If you are at 49F vent temps now, and your ETS is on the far/warm side of spec like mine was, I'd try a parallel shunt in the 80-85k range (90k if you want to be a little conservative). I took a photo of the mod, soldered at the stock connector housing, but haven't uploaded it to my website yet. Stay tuned, I can probably do that soon... I also have the more complete original write-up from Stu Ritter or Richard Easley. I'll post that too. (I'm still not sure why an "in spec" ETS gives such poor vent temps... my theory is that something in the climate control brain pushbutton unit is also on the far/warm side of spec, and the two tolerances add up to lousy vent temps! Not sure if I can prove that though. )
