hello,

i just got my buschur 65mm throttle body in and was wondering if anyone has any tips on setting the TPS correctly.

I have searched the forums and guides and found nothing, unless i'm not searching for the right thing.

Anyone know any good tips or a good guide to point me to?

thanks.

 

to do it properly, you'll need a 5v power supply & a volt meter

there are 3 prongs on the tps. actually there is enough space for 4 prongs

1 2 space 3

power output -------- ground

mitsu asks for 0.635 mv +/- 0.100 @ idle

just try to line up the old witness marks on the tps, tha twill get you close. if you have a safc or something that tells you tps position, just tweak the tps accordingly to get you back to what your original idle angle was at before removal.

 

wow thank you, and yes i have an S-AFC to test that. thanks a lot.

 

I suppose I'll bring this one back from the dead. . . A quick search didn't net me the answer I was looking for about what the TPS should be reading at idle in %. I suppose, according to this post, it should be 12.7% +/- 2%. I changed my shaft seals a few weeks back and made index marks where the TPS was insted of doing the smart thing and looking on Evoscan to see what the reading was. (Not that index marks are bad, but the exact starting % might have been nice.) I never really made a mental note of what it was to begin with. Right now it is at 13.333%.

It seemed a little high, because back in my DSM days, I would whip out the trusty Palm and adjust the TPS to as low a % as it would go while still reading 100% at WOT, and it was usally in the 7-8% range. Now I know and maybe this post will save someone the 5 seconds it takes to do a little division and multiplication if they are too lazy to hook a multimeter up to the TPS or just don't have one. This is just assuming that the TPS reads 100% right at 5V, and not at something lower or has some kind of non-linear scale to it. Please throw some imput in here if it does or if you have some other kind of crazy TPS percent reading at idle. Thanks.

 

what if Im getting no resistance on step 4, between power supply & TPS output?
