Think I replied to your email the other day? If not I got the same question!

There's one partially defined AU I6 map floating about but it needs some work. Series 2 is another issue and needs more work. Ah yes, the work piling up already... so much for a holiday!

Jason

dont u just hate the long run-down and hang that these motors have?!

you guys have done a great job so far for the fordmods community and deserve the rewards (finacially) just dont up the price till ive bought mine....hehe

Q. when i (eventally:)) buy a chip (and prgrammer etc) to suit my EF could i use what i bought on an AU?

Uhm - Get rid of the idle control solenoid all together and see how much rev hang and run-down you have then... It's simple enough to unplug it... Give it a few revs, drive around the block... Go have some fun, and then plug it back in and see how much it pisses you off.

Obviously you may need to play with the base idle screw a little first, but do try it.

Lol spot on, remove or block off the ISC and there is no rev hang at all. Cold starts will be fun though unless you bump up the idle a bit

Yes but wont disconnecting the IAC ruin my idle?!

Just try it. It only ruins the idle when you first fire it up in the morning. Although I do have a larger throttle body installed now, so can't tell you exactly how it goes on standard...

Anyway - It's easy to reconnect again mate - Just plug it back in! Couldn't be easier.

You don't need to remove the unit - Just unplug the connector.

nah im not interested in s**t idling. Also, what about power compensation when u load up the engine with A/C, power steering and going from Neutral to gear??

I'd much rather put an interceptor between the IAC and computer, which would only allow IAC activation when revs get below 900rpm or so.

Im pretty sure with the J3 chip there is a setting which controls how much the idle can fluctuate before the ISC kicks in and trys to correct it.

Jason,
Dont suppose you have any further ideas on the situation Im having with my chip?
Tried 3 different chips now without luck and going to try another ECU now.

MATE --- I am not suggesting you leave it like that for bloody ever. I am merely saying "TRY IT" as you were crying about "DON'T YOU HATE THE REV HANG ETC ETC" in your post that I answered originally.

The J3 chip can change the DASHPOT variable (or how fast the Idle Control attempts to return to zero) but I (and a lot of others) have found this to be too slow for manual geared cars.

Crissakes man. Have a bloody chill pill or something.

Maybe my ISC (and heaps of other peoples as well actually) is rooted and therefore it doesn't work quickly enough or something. All I know is that many many many people do get entirely fed up with it and throw it out, restrict it's airflow, or spend many hours getting frustrated with it.


And all I said was "unplug it, see what it does, and plug it in again".


What the hell? Hardly worth getting all carried away over mate.

As for """I'd much rather put an interceptor between the IAC and computer, which would only allow IAC activation when revs get below 900rpm or so."""

Tell you what I do currently --- I have a switch. Simple as that. I can turn it on or off whenever I like. Easy huh?

If you want to turn it on at (or below) 900rpm then a very simple circuit from JAYCAR can do it. It works like a relay based on pulses. Hook it up to an RPM source to turn on below 900. Costs about $20. Look it up.

Might be cheaper that an "interceptor" or what have you?


Anyway, have a great day.

Isnt that circuit thing for jaycar, that you're talking about, classified as an "interceptor" ??

I don't know.

well i can tell u that yes, it is.

No, it is not.

It is a frequency (RPM) switch, not an interceptor...

...and that is only a bandaid solution.
if it wont idle correctly, then either the base idle is way off, or the tune is not suitable for your cam (lower vacuum reading at idle) and there is really only one way of correcting it - tune it to suit the cam, either j3 chip, or aftermarket ecu.

The only problem that im having is that the factory computer activates the IAC on engine run-down (rev run-down).... which ruins fuel economy and engine braking.
