Need help adjusting Throttle cable after 102mm install? UPDATED WITH VIDEO!!!
Ok so I have a 102mm t/b that I just installed. Now on the arm on the side of the t/b where the cable hooks up there are two slots. The 1st one only allows me to open the t/b open to about 80%, the second slot leaves the throttle blade open a little bit having it idle around like 2500rpms because of it but I can open it 100%.
I talked to Jon at Texas Speed and he said I need the cable on the last slot and there might be a adjustment on the cable by the firewall. Has anyone done this adjustment before, if so what does it consit of?

yea there is an adjustment on the cable itself.. trace the cable from the tb cam up until you find a portion of the cable that has a small black snap on cover on it. Inside this cover is a spring type assembly that allows you to loosen/tighten the slack of the tb blade. Just mess around with it and you will see how it works.
If I were you, I would remove the lid/bellow/maf assembly and just have the tb blade visible while your adjusting the cable. That way you can see when it is completely closed as you adjust the cable etc. After you have adjusted the cable approapriately, make sure to hold it in place as you snap the cover back on.

Saw the vid.. pop the cover off the TCS. There is a small green rubber stopper toward the bottom. Take a pair of pliers and remove it CAREFULLY. Then try the throttle body blade opening/closing. See if it makes a difference.
From the video, it is apparent you don't have enough slack in the cable because you have to manually push the cam forward to bring the blade shut, this happened to me after I put on my NW 92mm tb, but I just kept adjusting it until it worked.

you really should only have to adjust the cable that goes to the throttle body, not the one that comes from the gas pedal through the firewall.. what I would do it just take the cap off, watch the tb blade, and push and pull the cable with pretty good amount of force.. just see what happens.. don't be scared you won't break it.. the PTM tb and the NW TB are very similar and you only seem to be needing maybe 1/4" more of slack.. its frustrating I know lol but you'll figure it out man
if you still can't figure it out, I'll go out and **** with mine and screw it up and then document how I fix it and take pics of where my spring thing is inside the cap if need be just lemme know

Here is me playing with the throttle by the tcm. Notice how when I give it throttle it dont go back down, I have to do it by hand.

Ok so get this, I think I pretty much have it adjusted correctly having idle giving it gas here and there and BAMMMM the car just turns off. Go to crank it and it just cranks but don't start. This has just been a nightmare.
I checked all fuses. OK!
I checked all grounds. OK!
I checked battery voltage. OK!
WTF is really going on, LOL!

I am fighting the same exact battle as you with a nw 90mm! Please let me know if you figure it out! I am going to try and trace the throttle cable back like the previous poster stated. When I run the first slot the car idles perfect at 800 rpm but the tb gets stuck above 2k. When I run the 2nd position the car idles at ~3k. Banging my head as I type!
