no I'm not showing anything, I'm asking for it!!! is there any link for it anywhere. I read the stickies(all images have been deleted(not cool)) and no explanations for the iat trick.

I read some threads on it and it makes sense plus with a switch, you can run full timing N/A, but theres no pic of the install anywhere...

I never used it, but here is the diagram

thanks!.. can you pull up to 4degrees of timing?

On your '98 2° is the limit, unless you go into the tune and change the amount in the degrees you target. See the HSW Interface thread and it'll explain things for you. By the way, the Interface is a much better option for pulling timing this way, and you get universal a/f tuning too, a killer product.

Yep, I saw the interface and I'm really thinking about it...but I'll need a window switch anyway..but since I'm going wet, not sure I need the interface because it has more features for a dry kit. I'll re-read about it! it looks like a must-have piece!

thanks robert

Actually it works just as well for a wet hit. You can fine tune any a/f you want. Never does the wet kit come with exact a/f, OK, one out of 10 may have an a/f that's acceptable. however, the Interface allows you to adjust a/f a couple hp in any direction, very difficult unless you have a box of all the size jets needed for the area you seek. So, it's a good tool regardless of style kit. think about the DP wet guys, no more juggling up to 16 jets to get optimum a/f.
Good luck on which ever direction you chose.

one Q for you Robert:
Since I wont get any tune for my NOS(except wideband), is the interface still a good choice?

the fact is a tune around here is 1000$++ so nobody does it in my town...3hours drive to spend 1K$

I'll ask someone at HSW too, I just bought em a sudden impact kit and a FPSS for a starter...

Thanx for the diagram.

Caribe, I sent you a PM But maybee there is someone else that can answer this, on the 750 ohm resistior, what wattage?, and what amp relay?. Thanx.

I've been thinking about doing this mod. I have a 100 shot on my 2000 SS. Can't this pull 4 degrees? Which would be enough retard for a 100 shot right?

If you look in the thread I refereed to earlier, I posted a screen shot of the Z06 IAT table which allows more timing to be pulled. Well yours will show a max, IIRC, of about 2 degrees no matter what temp you seek out. Unless, you go into the tune and change the degrees to be pulled at the temp you do your resistor at, you'll be stuck with what the stock IAT table has. Look into the data base in the tune section in stickies for your car and look up the IAT table, then you'll know what you have.

Most any relay will work, the amp draw will be very, vry small. wattage as in ?
Robert

Hell yea.

Alll resistors have a watt factor I beleve, I figured it to be around 2.8 watts for the 750ohms @ 12v, but I was told it does not hurt at all to go larger witht the watt factor, I was just curious watt you all were using for a baseline. Thanx

Ok thanks Robert. If i do this iat mod i will alter my tune to pull more timing

I Have The Interface And Am Probally Just Gonna Sell It As My Dry Kit Didnt Require Any More Fuel Past That That The Nitro Dave's Halo Already Told The Maf To Add So All I Need Is The Resistor Mod Or Just Tune It Out With Hpt

Quoted for truth!

The HSW is an advanced resistor mod, very advanced, but same principal.
Here's a few diagrams from my web with more info in my wiring section.

Im Thingking To Wire The Relay To My Window Switch.. I Also May Just Move My Iat And Set Hp Tuners To Pull Timeing When Its Really Cold..

What I Have Noticed Is That If You Modify The Iat Table For Extended Usage Of The Interface Or The Resistor Mod It Will Effect Driveablity On Hot Days Hwne The Car Becomes Heatsoaked.... You Can "kind Of" Tune Arround This But It Will Always Be There

If you have HPT or EFIL, select a resistor value greater than 105K and it will force the IAT to the bottom of the table, -40degF, which is currently 0. IF you have an 01-02, pull timing from .60g/cyl and higher. If you have a 98-00 use the 95 and 105kpa cells in the -40degF column. If you have an 01-02 (or 01-02 OS on your 99-00) you get a PE modifier against IAT also, which will let you add or subtract fueling from WOT, which is sweet
