Okay, after some careful jimmy rigging I successfully got the TPS off without removing anything, but I ended up dropping it down by the exhaust, SO I carefully remove the TB WITH the intake hose still attached so, since I FINALLY got it to not leak.  So, anyways, I swapped in a slotted TPS, brand new, and since I was the only one to there I just had to guess, I got it to 0% TPS with 0.39 volts, it had the smooth no jumpy situation and ended up with 4.08 volts at fullest 100% with the the cables hooked up.  

Oh, for the side note, the cat is brand new, so I wouldn't expect it to be bad, emission test next week with determine that for sure.  The black soot from the exhaust at idle has gone since I re-did everything took which is good.

Crap :cry: , sorry things got difficult on you, but sounds like you got things proper again with the TPS!  Yea long as you have 0% to 100% the computer will work well with this engine?s sensor.  

So after today?s drive let us know how it works now :) !

Some thoughts on boost levels now that the chip can do what it?s programmed for, if the boost goes real high at first then the wastegate DC drops, it might be the turbo is either clocked a little off or the wastegate rod is threaded and a little tight.  The boost level the chip is shooting for with no knock is the levels safe for premium gas, and if it finds the need to back down the boost (not from knock, which you don?t have either) then its doing its thing to keep the boost at safe levels for punp gas.  And yea I am too lazy to figure it out and since its your scanner, you are going to have to convert those 2 bar kPa levels to psi for me :lol: that since the McLaren chip document I am use to using shows all the fueling and timing tables in a 1 bar range (0-100 kPa) so that is what I am use to dealing with, which is not a mistake or a problem, there is a 2-bar flag in the chip that makes it all work just fine.  And whether it shows a 2 bar or 1 bar scaling in the fueling and timing table doc does not matter since you can call it anything you want long as there are enough entries in there covering the full range of load and rpms, though if it were a 3 bar running in there the resolution would suck  :roll:  .

Hey Jeff, google.com has built in conversion calculators, you just have to type out "kilopascals"(example: "180 kilopascals to psi" use that format and it will give you your info in bold face type just below the box where you type the text in.) instead of of abbrieviating it. Pretty handy. 8)

Thanks for the offer/link, I do have lots of charts like that but as I was complaining about with TurboGTU is the accuracy of what the data stream tells you verses what is.  And fact is when I look at lets say 85 kPa (don't quote me on the exact values there, and this is the 1 bar version in our chip tables I am referencing) and it's supposed to be 10 psi, its not on my accurate boost gauges, close but heard too it can be off more down low.  So I was also hoping you had an external boost gauge, but not critical, just hope things are running better now?

Well talk to you later, off to a big local powerhouse tuner/engine machine shop Car-B-Q :lol:
