ok, just got a unichip and probably won't install it until it gets warmer. So I'll get into this forum. However...I have a few questions.
1. last winter I had a big problem with studdering/fuel cut, this winter its much better<whatever. My question is, do you think map B would be OK in REALLY cold weather (basically 10 degrees F or below) driving? Would it help out the fuel cut issue?
2. Why does boost cause the fuel cut in really cold weather? I thought cars liked cold weather because there is more oxygen.

Looks to be an non p-n-p version. Dastek makes the Unichips sold in North America too, correct?

KZL_99ES, I would try searching on some UK and Australian/New Zealand sites, see if you can find info based on your unit off its model number...

Here is the link to the thread I started when I took my MSP to get its Unichip tuned to the methanol injection kit I installed: http://www.msprotege.com/forum/showthread.php?t=123684236&highlight=unichip+meets
I also agree with mspHtown, in that I think it is wise to upgrade your intercooler first, and then add the methanol kit on top of thatthis proved to be the way I did things and it has worked out very nicely.

Can the unichip tune WRX 440 injectors? I been hearing that it can tune fine in the higher RPMs but not for idle properly? how many of you have the Unichip with 440s and whats your results? i wanna debunk this myth (if it is a myth).

I believe that MSP's will run very rich with 440's because the UNICHIP will not be able to calculate a proper A/F mix. Don't quote me, this is based on a conversation I had with Boomergt (300whp built msp) a long time ago. He ended up selling and going with the Microtech unit. And this is not because he doesn't believe in the UNICHIP as his current car (G35 coupe) with Twin turbo uses one.
programmable? yes... and no..
you cannot program it but some shops can.. but you wont be able to edit anything it at home with a labtop..
There's a sticky at the top of this section that's all about the Unichip -- info as well as any questions anybody has goes there, so we aren't overrun with a bazillion Unichip threads.
This thread has been merged with that one.
To answer your question, the Unichip IS capable of being 'retuned' .. however, not so easily. You have to either hope you have a tuner-shop nearby that has the Unichip software, or you can send it to JDM Sam (a member here on the forums) to tune it for you.
Some other often-said advice -- use the search button. You could've easily found your answer with it.

I'm pretty sure that the Unichip will run fine as long as you get a 'personal tune' with the 440cc injectors. I believe you only run into problems if you try to run the larger injectors with the 'stock' Unichip map.
I'll be finding out the answer to this question personally in the spring, though.

Let me know how that goes Rush. I've got some 440's sitting here right now (actually had them since summer). I'd like to get them in soon but will need a tune. Did you say you're going to a shop around you to get the Unichip tuned?
Unichip Info
I'm looking at getting the Unichip because I found someone selling it at a sweet deal but was wondering if its safe to install without replacing the mid-pipe with the mods I have on the car already:
-Injen CAI
-Hard Pipes
-CustomMSP SMIC
-P&P IM w/ VTCS removed
I don't plan on using the boost controller and just leaving it at stock boost...at least for now. I'm just a little paranoid that because of the the restrictive cats it my create far too much back pressure and cause some serious problems or worse (zoom-zoom-boom)

Your car is near perfect for the base map on the uni. I would free up the exhaust a little to get as much out of it as you can, but you'll be great just plugging it in. The only thing im not so sure is it might not like the VTCS being outta there. I feel like i remember Sam saying something about that being a pain in the ass on tuning when he was doing my chip.
Okay, well we got the methanol in, but right now the local dyno has a Porsche 911 race car with the suspenion apart in front of the dyno, so no go till next week on the injectors and tune.
From the few light pulls I did with the meth I could definitely tell the difference. It was wet out so I didn't get to hit it too hard, but you can tell when the meth kicks in. It's almost like you don't really gain much horsepower without the tune, but you get your peak HP pull after pull with the cooler charges.
Also, the Snow kit I bought from SpeedCircuit wouldn't work! The tube would have to be too long to mount the larger resevoir in the trunk so we ended up relocating the battery to the trunk, and mounting the meth resevoir where the battery used to be. Looks super clean, but was an unexpected problem with the Snow kit.
Cost me a little more, but it looks so nice, and I don't mind having the battery in the back. So all is good.
I will update next week with the results and graphs.
