The sensor on the back of the key lock cylinder is for the stock theft deterrent system. Take it off, unlock your doors and open them, you will set off the alarm.

If you still have the stock o2 and didn't cut it's wires, you don't need the nb output of the PLX. What code are you getting?

I wouldn't call it a failure. You're hosting the complete downloadable, searchable, pdf version. Plus a downloadable version of the cygnusx1 site. I have seen your http://filecab.supra-tsrm.com/ linked to on other forums too. bigal0043 - I have several images hosted on your site - Thanks!

How exactly did you do that? What other options did you install? What other wires did you touch? Did you replace the stock o2 with this one? And what code#? procedure here

Thanks Topher E robbo185 - well, you tune what you got, to get the most out of it. Yes I will have to tune again when I do the fuel mods, but I tune continuously anyway. I have the ZT-2 and log regularly. :)

bigaaron - I'm really glad to see your results with the 50trim upgrade. That is exactly the mark I am shooting for. 268 HP / 299 Torque After the dyno I found out I have a bad igniter, threw a code 14 :(. I think that is what caused the jaggedness.

This past Saturday we, my girlfriend, her son and I, went to Tulsa for a meet with local Supra owners and a few others. Dyno was the main event. It was a smooth trip from Oklahoma City to Tulsa. Car ran perfect. When we get their, ten people are already signed up to run, so I’m on the list...

With what unplugged? Do you have something normally connected there? With it open, like the picture, it is a huge vacuum/boost leak. You will have very poor engine operation. Lean at idle, Rich at WOT. check over all your vacuum hoses -...

yes

Yesterday I threw a 31. I disconnected my SAFR, installed jumper wire, and code went away. So I recalibrated the SAFR and everything seems fine now.

You know your codes. Now pull the EFI fuse for a minute. This resets the computer. It will drive a bit rough while relearning ~20min. Recheck everything you came into contact with when you did the oil change. Check you wiring connections at the ECU and the sensors - tps and knock Check...

Thanks da89soup. I did find it. Just what you said.
