so the sikky wiring service should still control the a/c and heat correct? also starting up the car in stock-ish trim shouldnt be a problem if the VATS is still enabled? im breaking it in on a stock e38 and stock tune before i bring it in to get hp tuned.

 

No. I'd expect that A/C control is an extra feature since it didn't come with mine but quote me on that. Another thing to remember is that getting the A/C to work require some custom lines. Best way to know for sure is to call sikky.
The VATS will still be a problem unless its disabled. Depending where you get your drop-out motor and trans sometime they'll disable the VATS for you as a service but not everywhere offers that.

 

will i have problems on startup with the vats still enabled?

 

If I had to guess I'd say yes. You may need to do some research on how the GM VATS functions. If I remember correctly I think it's ignition key specific.


Updated: Found this on VATS

I spoke with JE Imports yesterday. You mail them the GM ECM and they will disable the vats for ~$200. Tuning is a separate charge on top of that.

When I PMed Sikky I was told that I would need to install a separate on/off switch for the AC. I PMed back asking if the heat/cool and fan speed controls still work and have not received an answer back yet.

I went back and re-read some of the earlier posts and feel somewhat mislead:

SIKKY:
I didn't see an AC line kit on their site and JE said they didn't think Sikky was mass producing the lines.

Maybe we can get a swaps sub-forum where we can start (or move) our individual build threads so others can see the options and all the steps involved such as wiring, hookup of sensors, modding the cluster, AC issues and so on. That way we can have some definitive answers to questions.

Havok, Snyper, Quamen... are any of you guys running AC? If so, do the factory controls work at all? It seems the AC controls may be in the canbus with the tach.

 

None of them have AC.

The only thing that kept me from the swap over my motor build was the lack of people that have done it. tough enough making a proper VQ build with a bunch of shops support.

 

Good info on the VATS... And I also think we should have a separate sub-forum for engine swaps or hybrid engines. That would help out a lot...

 

I agree

 

ryans has no ac, or any creature comforst to be exact lol.

i found this website for ecm reprogramming
http://www.pcmperformance.com/programming.html

then i also found that they do vats delete through an ebay ad for $110
http://cgi.ebay.com/ebaymotors/GM-VA...-/150484707224


now 1 more question arises...before we were to send it in for a vats delete, would anything else need to be changed? reason i ask is i keep seeing things like this on multiple pcm flash option lists

Speed calibration for axle ratio or tire changes


i have a 3.3 fd from my old build swapped in and no longer have my factory 3.5 so i wonder if my speed calibration will be off. also, my pcm came with a nifty egr delete, skip shift, and no speed/rev limiter. nifty nifty

 

bbs,

I still have power windows :P

 

silly me, how could i forget

 

Same Here. I also wonder if the GM ECM can have other things done when the VATS is disabled, kind of like an UpRev flash.

Things are beginning to look more complicated than just plug and play. Still haven't heard back from SIKKY about the AC controls, so not assuming thats good news. I MUST have AC... period. I'm fine with hiding switches in the cubby or whatever.

I'm leaning towards letting the car be down the whole year rather than try and get the swap done in a hurry and miss things I could have changed if I wouldn't have rushed. Lots going on at work this summer as well

 

If your going to try to use your ViPec, do you need the GM ECM?

 

I haven't really missed my A/C yet probably due to the fact that I work nights and don't drive it much during the day. Yes. I'm Batman.
All my climate controls work like stock except I just don't get A/C cooled air. You'll probably want (NEED) it if you live in a hot climate region like Texas though. Sikky may not be mass producing the lines YET because there's not much of a demand YET but if you must have them now they can make them. At least Sikky offers you an option.

There are a lot of parts still under development at Sikky that you wont find on their website. I'm still waiting for an update on the improved Sikky sway bars for this kit.

 

That would be one of those rush vs wait issues. Who really knows what I do and don't need. I do think the VATS is a must though.

This is a huge relief, so then it would just take a separate toggle switch to turn the GM AC on/off.

I work 3~4am twice a week making our deliveries into downtown Baltimore, constantly thinking about how much fun the car would be on the completely empty roads and highways.

 

^i love driving late late night when the roads are dead...just worry about the sheriffs lmao. so i would imagine the ls a/c unit would just need custom lines, which mates directly to our a/c condensor? also, if we spliced the ac wire on the z harness into the ls harness (its only 1 wire for the z harness) and using the condensor, couldnt we control the ls a/c with the factory controller? or even better, if we could fabricate a mounting solution for the z a/c condensor in the ls a/c location we wouldnt need any wiring riffraff, just custom lines, to which it should operate like stock then id assume. lines would be fairly easy to hide as well (inside the fender)

 

Thinking about this more and more. I will try and do some research on the LS forum to see what they say also maybe that no rotory Mazda forum for swaps as well.

Quaman, you're on a full stand alone right? What did you end up doing? I need to go back and read through your entire thread.

These are questions that we need answers to for sure, but whom do we ask?

 

cass to answer your questions, ryan utilized the stock 350z oil pressure sensor and plug, oil pressure sensor and plug, alternator, starter, power steering pump, so it would start up like stock, the standalone controls everything else i believe.

also, i think i am going to attempt to make a custom bracket for the oem z a/c and work off that

 

That is correct bbs. I used all the stock Z sensors so the gauges still worked. I also made my own brackets to mount the stock Z power steering pump and alternator for less of a wiring nightmare.

The standalone I have uses it's own complete wiring harness so wiring was extremely easy since I didn't have to try integrating anything.

 

Considering doing the same thing with the accessories, kind of surprised that nobody has made brackets to do this that are for sale yet (You should do this Quamen... I would pay to have it done ). I suppose I will have a friend of mine with a machine shop stop by and take a look at things and get some measurements so he can work up a price. Still doesn't solve the tach issue though.

I need a primer on what all the sensors on the LS2 do and where they are, then get with my ViPEC guy and see what can be wired in and controlled. Right now selling all my old parts is taking a large chunk of time.
