This is similar to the way the current WRX software works. With the added AFR Target map and VE correction table we gain the use of the IIRC 32x32 background AFR map it could actually be more but this is what works well. With this map set correctly you gain resolution but also it becomes much easier to tune, in the VE correction map. I also will be getting the launch control, flat shift etc. back into the software suite.
As we get closer I will let you know.

FWIW, I would be willing to PAY for this update.. The sooner we can get our hands on it the better..

Software has always been free. I'd probably be lynched in public if we did charge you.

IMO, I wouldnt mind paying for an upgrade..

Rev-up support? If you mean cam phasing control. I can tell you that with certainty the current UTEC does not have the ability to control the exhaust cam. While we do have the hardware that could control the intake cam, I think the resources are better spent on updated engine running code.

I totally understand.. I was in the software biz a few years back and had that problem.. We spent more on R & D to be able to lock down the software to each cpu it was ridiculous.. They finally started to 'clone' laptops and make each one look the same and sold the laptop with software installed as a complete package
Anyways.. No worries about leaking here...

Like I said, though, nothing that would make me not want to get a UTEC.

What I have found (and heard from others, as well), is that there is some hesitation/slight power loss at about 2700-3200 RPMS with Rev-Up motors and the UTEC. Nothing to kill the deal, but enough so that you notice it. For all I know, it might be totally unrelated to the the Rev-Ups, or it might have more to do with the MAP sensing. Regardless, you can almost tune it out, but it creeps back in after the tune.

Slight hesitation? Sounds like tuning to me. I have a local customers who have never complained of such a things. This is the perfect forum to seek help for such an issue. IF you or any one has datalogs of the issue feel free to post them.

Hey, just wanted to backup what Dave has said. I get the power blip and its only there at certain times not always. Also im forever living with the P1444 code. Im praying to get rid of that code, thats the only thing being thrown and it seems as Dave has said to be an altitude related thing. I love my utec and i wouldnt not have it but these are two things id really like to try and get resolved and would be willing to work with you to find ways around them. Our shop is looking for someone to help with this as well as they have a large number of customers facing the same issues.

i'm still having a hesitation problem around 6200-6500 rpm. I've done the grounding fix and still having the problem. I also have a hesitation after every time i shift. SGP says that it is the way i shift but i can granny shift it and it still does it sometimes. Anyone have any suggestions.
