Sounds worthwhile on non- boosted cars :-) Another PorKen triumph !

Words of wisdom as usual. Corky Bell has a new book out on SC with chapters on Eaton, Twin Screw and Centrifugal. With an IC I should be safe at 10 pounds boost, but that's why I'll probably monitor intake temps. He also discusses knock sensors. but I don't want to open that can of worms.

Remember, I said seems to work. I only drove it for less than an hour, and I could be:![](https://members.rennlist.com/porken/smiley_joint.gif)
Here's what the harness looks like:
![](https://members.rennlist.com/porken/EZFTempIIBypass.jpg)
Looking at the Temp II sensor from the top, the two sensors are positioned (AFAIK):
.__-__.
[LH|EZ]
This is how the bypass is wired:
L - E
| - |
| - 2.2K resistor from RS
| - |
L - E
The wiring diagram shows the wires as LH - solid green, EZF - green w/red stripe, but mine were green and brown w/ red.
The connectors I got from '80s Audis from a U-Pull-It. The male is more difficult to find. The outside temperature sensor connector - drivers side front grill - is a good one.
Careful with the Temp II connector, the insulation on my wires cracked when I was installing a new sensor, and the copper was exposed. I used some liquid electrical tape on them.

Hi Rick do you have more details (title, publisher, ISBN) of that book ? Sounds like a good "hint" for a Christmas present for me :-)
I think you early 32v boostards will need some retard at the top end. I assume that some of you already use the "octane loop" to achive this ? It is ideal as it only retards mid to high load values (although only by 3 deg which isn't really enough.)

John,
Will the EZF listen to both the full throttle switch and the idle switch at the same time? IE combine 20° + 10° retard?

30° retard would be terrible, EGT would melt the exhaust (dramatic license).

If it is the same as the later LH, then no, it only listens to one map at a time.
Later EZK has threee main maps, idle, cruise and WOT.
We will discover whether LH2.2 EZ-F is the same in due course....

Hi Rick I just double checked and it is the same ISBN as the 2002 book by Corky which I have a copy of
The front cover is slightly different, but same ISBN so I assume it hasn't been updated.....?

It does have more torque at part throttle, and needs less pedal while highway cruising.
I almost got in trouble again with these 225s, as I gave it a just a little gas (no kickdown) on a wet onramp, and sho'nuff, the rear end started corkscrewing towards the barrier.

Hi Rick,
OK, thanks. I have both books :-)
