tls tps voltages needed

[bigworm]

hi all

need some base settings voltage wise from the tps

im installing my tps onto my 999 throttle bodies and im after the voltage of
the tps at rest on a tls so i can set it to run on my project

infact if anyone has a graph and mapped the voltage increases per degrees
that would be great

also does anyone know the degrees that the throttle plate is open at rest

Re: tls tps voltages needed

You don't have a stock pair to look at?

You could just use the TPS resistance value of a closed stock pair of TB's to get a starting point rather than a live voltage reading. Plus the voltage reading might be different between different bikes depending on the exact value of the +5V output from the ECU.

The Throttle plate moves nearly 90 degrees, how many degrees does the TPS shaft turn?

Have you looked at page 4-39 in the maual? The resistances are there.

~1.2k at idle
~4.4k at WOT

cheers steve
was going to take the base settings from the set i have
but couldnt remember if ive adjusted things since they had been removed
that'll teach me
but going by the values you gave me, mine were'nt that far off(1.10-4.85)

i take it that the tls tps is a linear type from the steady increase in resistance

on measuring the 999 tps i was a bit confused as it is stated as being a linear type but the reading went up to half throttle but dropped back from there to full throttle (1.4-3.04-2.58)

where is the link for the manual,i'll be able to tell how much degres open to set the butterflies at idle in accordence with the tps setting

I've got the manual and stuff here >> http://wotid.com/tls/content/view/26/74/

The manual shows it as being linear Page 4-15

Re: tls tps voltages needed

looks like the 999 tps is faulty then

never mind as its much easier to use a backing plate and use the tls tps on the bodies

1 question though i cant find an answer too, is the butterfly fully closed at idle and what is the setting if it isnt could try and measure mine but i wouldnt know if they are out in the first place

ps cheers for the help

Re: tls tps voltages needed

The TLS TPS is linear indeed, but be careful that you measure correct. this is a linear voltage divider!

Re: tls tps voltages needed

The plate aren't fully closed, they have ot be cracked enough to let enough air in for idling.

The air bleed screws on the TLS aren't big enough to keep the engine running on closed plates. They just help with some balancing / syncing fine tuning.

Exactly how far open they are? Not much.

Re: tls tps voltages needed

guess i'll just have to set the butterflies when i come to set the tps when its installed on the bike
as in the video

Re: tls tps voltages needed

the reason i ask about what degrees the plates are open by on the tls is because on the 999 they are open by about 2.4 degrees and the tps is set via software

but being as the tls tps is mechanically set, i dont think i'll have any probs when it comes to setup on the bike as the tls is much more straight forward to set
