And what setup are you running?
Thanks for the proposal, but let set up my mind first.

i have an opcon autorotor supercharger. I had it with only larger injectors and adjustable FPR but impossible to fine tune at all ranges. I am in the process of revamping it since it was just a quick put together initially and also adding an air to air intercooler, Split Second FTC1, 32lb/hr injectors, wideband O2 sensor with programmable narrowband O2 output - check my supercharger install thread in the Member's projects section for details (i thought you already looked at it but i gather you have not seen it yet) http://4bangerjp.com/forums/index.php/topic,7334.msg54415.html#msg54415

Till now I was looking for turbo mods only, now I see they have very much in common.

Yes, I did read your thread. Very nicely done. When do you plan to test it? I can see a problem in a long intake like yours. Since the throttle body is before s/c all pipes and intercooler will be sucked by the engine at closed throttle, and than it will take time to fill it again. I'll be happy to be wrong.:)

will fill up faster than a turbo with the t/b downstream (the s/c starts to make pressure at at about 1200 to 1500 rpm)

I like this setup. Water to air intercooler, separate cooling system, very short intake. With your skills can be easily done, I think.

i did some research before deciding which way to go

advantaged of air to water intercooler (usually called aftercooler): reduced size, reduced plenum size, less tubing routing headache, you can add ice but that is only good for a quick run (not my case)
disadvantage: less efficient (unless you use laminova type but then there is a pressure drop and you need a large radiator to keep up with the heat - a small one will be good for short bursts and not constant boost), way more expensive

advantage of air to air (i use a bar and plate type): efficiency, less pressure drop at same temp drop, cheap
disadvantage: more complicated to install, larger plenum, more piping to be routed in and out of the i/c

usually you will see the s/c with an air to water intercooler and the turbo with an air to air but i did find that some offer air to air kits with good results so due to cost and few other factors that was my choice in the end.

PCM must see real temperature of the air taken inside. So, what to do? 

Get it close enough? That's what a lot of people do. You try to tune it as well as you can with the tools you can get.

Jeeps weren't designed with possible forced induction in mind. Some of that has to be compensated for with math and guesswork.

That is also my choice but for turbo setup. Also TJ is my DD and I don't go much wheeling, no rocks at all.
Hope your setup will work well.

Is it the right model of split second - FTC1-019B?

works on my Jeep although is a rebrand not Split Second direct purchase so whatever their model numbering is won't be the same on the one i got.

Do you have a kind of install manual? Looked at their site, nothing similar. May be some pictures of device installed?

i have the wiring harness splices in with a male/female 10 pin metric pack connector - i have 2 other male/female connectors on the unit harness - so I can disconnect the 2 on the harness and plug in the ones on the unit and the Split Second is in between sensors and the PCM, if i want to get back to stock simply unplug the connectors and connect back the 2 on the original harness.

I didn't get a chance to post pics and details in my s/c writeup but it's coming.

They have the manual on their site, is the same as the Dodge V8 one they have there if i remember correctly. They do have the PSC1 manuals as well, St. Chevrolet went with one of those.

Can you say smth on this gadget: http://www.innovatemotorsports.com/products/ot2.php
I'm new to tuning, is it a good replacement for laptop or just a toy? I have iPhone on board anyway, just though can watch my OBD II online.

it's an interface with OBDII. There are others out there. If you're planning to buy other things from them then it's worth it as it will integrate over their MTS link, if you don't you could probably find a cheaper one. Nice thing about OBDII is that you can monitor all the parameters without having to splice into the harness (that's what i had to do to get my SSI-4 and LC-1 and connect to my laptop) and you can also monitor the fuel trims and codes via a laptop interface. At $179 with the capabilities that it has i would say it's a reasonable deal.
