yup, sure did. i no longer had anything going to the nipple hanging off the elbow. i sawed it almost flat, filled it with some permatex plastic bond stuff, the 2 part epoxy crap. after it dried, i drilled it and tapped it (m10x1.25), put some gasket maker on the threads and screwed the sensor in. i made about an 18 inch extension for the sensor plug to make it reach and stuffed the hole under the uim with a shortened m10x1.25 bolt.

all in all, the response is much quicker to temp change and doesn't reach nasty high temps when sitting still. i used to see 60+*c in traffic and now it hasn't been over like 43*. i haven't noticed any real gains in performance yet, but i was bored and it was a fun couple of hours

matt was kind enough to send me so pix but it was on the IC piping. i need to see it on the stock elbow and since you have the stock elbow can you take a pix of the writeup?

i don't have a digicam, but i might be able to get pics within the next couple of days

Are you guys doing this with the stock ECU? Has anyone tried it for the stock ECU?

Most of us are running a PowerFC. A car with stock ECU will benefit from this modification. Only difference is that with a PFC, we can monitor the air temps.

Dat's what I tawt

that would be kewl...

i have everything apart as im puting my turbo back... so i decided to do it once and for all... hope it all works tho.. hehehe...

can you take a pix of the inside of the elbow wiv the sensor hooked up? tanx...

Heres a trick for you non drillers...
You can go get a 1/2" Rubber Cap at AutoZone. Wth a clamp will hold 15psi + easily. I cut a circle in the hole of the cap, went and got a 10mm Hex Nut with 1.25 pitch and put it inside the cap. I then added sealer and screwed the sensor into the hex nut and tightened it down. No leak.. easy fix with no drilling!

But I have a problem with my wiring.
After making sure all my connections were good and re-doing everything. Im still throwing a code!
Am I missing something here?
read my post: https://www.rx7club.com/forum/showth...hreadid=225673

I did away with the clip and just soldered the wires onto the sensor. IS that a nono or something?
perhaps my wire gauge is too thick? (all i had was 16 gauge) Do I need to ground anything???
please help so I can drive my car.

I wish I hadnt moved it thus far.

For PFCS users, in one of the sections is an "air vs timing" table. Since the repositioning of the AT sensor makes it run at about 10C cooler, you need to set the temps down 10C on this table in order to keep the same margin of safety.

Also there is an "air vs inj" which will slightly affect AFRs.


Return your AFRs.

If the body of the sensor is metal (I can't remember) it needs to be grounded. After that you should be fine.

Ok thanks Damon
I ASSumed one of the wires was a ground already.
So I will simply touch a ground to the sensor then and see what transpires.
Thanks for the info.
