Bugger. OK, I'll read into that a bit more. I can only borrow the tactrix cable for a very short while so I need to make sure I nail this ASAP.

Sorry to sound like such a novice, but which is the "Base ISCV" table you speak of?Quote:

Anyway, I don't have the $ right now for a tactrix so yet again borrowing one, now I have read the 'how to' idle section a few times now so I believe I should be fine in setting this up.
Questions were, Since running 272 cams in the 3.5L It's a bit of uncharted territory - I'm finding 950-1000 when warm is good.
I'm going to up all the values in the idle table by 300RPM to counter for this (as right now it's set at the stock 648 and I'm having ALLLL sorts of issues)
Do I; Need to adjust the AC ON idle table aswell to reflect the changes made to the Neutral Idle table?
And also, NO OTHER idle tables need to be changed even though I've made a quite drastic change to target RPM's?
you may have to change the initial isc position. I would set the idle slightly faster (like 50 rpm) a/c on than a/c off. You may also have to open the biss screw up to center the isc.
Thanks mate. Noted on the idle position re: AC ON/OFFm 50rpm is a good starting point. The initial ISCV position perplexes me a tad, i.e, does it need to be a few steps more? few steps less? or does this process involve me changing it by say 5, flashing it on, starting the car, and seeing what it does? Or should I just note ISCV position and see how the idle goes after changing the target RPM tables? (Also, unrelated, and if someone can respond by PM that may be better, but any reason why it's triggering both Rad fans, not just the main one, is this normal for an NA ROM?)Quote:

Cool mate. Thank you heaps! (Will report back after the weekend!)Quote:

If you'd like the logs please PM me so I can send them to you.
I just want to know, should I also change the "Target Idle RPM (Drive) field too?
Put my log through MegaLog viewer and noticed the O2 oscillating like CRAZY from 0.0x to 0.95x every few milliseconds..
It's a brand new O2, is this what it's supposed to be doing? Gotta ind out why the bastard has started hunting :(
