Just an video update. Plugs are black with fuel.

Is it throwing any codes? Do you have an o2 sensor other than this one?

RickyDavis

no codes or check engine light and yea theres one installed already

RickyDavis

ishootstuf was your car surging like that and what plugs are you guys using?

I don't recall the part numbers, but they are stock 2JZ-GTE NGK's. My surging was caused by bad timing, then bad coil or igniter.

Your timing won't be close if your TPS isn't set right - that was my problem. It will show MUCH more advanced than it really is.

RickyDavis

tried adjusting the tps and there was no affect

RickyDavis

also using the stock ge o2 sensor if it matters

You cannot use the metal odb1 Lexus mafs. You need the round black plastic maf that is Hotwire kind, that may work but not confirmed. I'f not you need a gte odb2 maf.
It would be nice if we can figure out some interchanges for that part

To which I am almost certain shares the part number with the Camry/Solara 1MZ V6 MAF.

I have been playing around with implementing JZ GTE ecu's on V6 engines, and a lot of the parts came up with cross-referenced part numbers.

Now the idle surges between 500 and 1k rpms. After looking through other threads of "idle surge" i found a thread on the egr removal causing surges. I have my egr removed so i'm looking into that being the cause of te surge.

Take a look at the 95 Avalon, it uses 6 coils and a TT ignitor.
I have used the ignitor on many TT coil setups as you can usually get a better deal.

I think you could rewire the firing/injection order, but I think on the v6 the firing angles as in timing on 2 of the 6 cylinders is different from v6 to I6. Now for injection it's prob not a big deal as there is a large window for that but ignition could be an issue if its different. Something to think about.

I noticed this from people using the 4 runner cap on our dizzys, then someone pointed out that the contacts for some of the cylinders are in slightly different spots. Good thing the rotor / distributor is forgiving.

I got a brand new "080" Supra TT TPS and went to install it, I switch the polarity and got a linear 0.68-3.99v.

If I switched back to stock, the tps is backwards and won't rev at all really.

Somehow I am getting a 21 and 41. o2 sensor and TPS.

The car idles really high with no TPS but I can rev it somehow,, and surges with the TPS installed but it won't rev up.

I am working on getting an IAVC and o2 sensor, but the car should rev up clean even without these things fixed.

Any ideas?

did you only swap the outer pins? maybe try swapping the inner pins as well because it sounds like your voltage is good on the signal line, so that only leaves the IDL circuit to point the finger at.

Everything is pinned correctly, I verified about 10 times.

I put the DVM on the TPS itself .68-3.99v.

When I put the DVM on the ECU side, I am only reporting 0.01- 1.09v.

I assume there is a bad connection and I should run a new signal wire, to give the ECU pin 0-5v yes?

EDIT: FIXED Got 0-5v at the ECU.

If this post is too off topic, let me know and I'll remove it.

I built my own "HKS Fuel Cut Defender". It's an adjustable voltage clamp circuit where voltage in matches voltage out until a specified max is reached on the output. I wish I could take credit, but my electronics knowledge is not as good as this:

I haven't installed it yet, but wanted to let others know in case they want to give it a shot. It was about $30 shipped for the parts. Most of the parts came in quantities of 10 or 100, so for another $60 I could build 9 more. NO, I WON'T BUILD YOU ONE.
