    That's right, you'll run a vacuum line to the box. We'll have complete directions when they are ready to ship, and include a suitable length of 1/8" vacuum line.

Im not sure because the Pro may have extra VR inputs (like the ultimate does), in which case, the ABS sensors get wired directly to the VR inputs.

    If it does need to be conditioned, there are very very small conversion boards available. Once its conditioned from VR to Hall, it can go into a Digital input.

    Dont worry about tuning it. Get a good base map ( i have several good tunes im willing to give up), take some timing out in boost, set AFR safety and get it dialed in. Once your fueling is correct, rent a dyno fo a bit and do the timing.
    I appreciate the offer on the setup files. My friend that has done a bit of aftermarket ecu tuning said the WOT maps are cake, but part/off throttle are the pain to get dialed in. Regardless, I'm really thinking I should just pull the trigger on this and just sell off my tuning setup and my racelogic and it would be a wash $$$ wise

    Hopefully Matt can chime in on whether or not there will be spare VR inputs. It's easy enough to snag them from the ABS module behind the glove box, but wondering if anyone suggests picking up the signal from somewhere else.

    Also curious if Matt can chime in on how many spare inputs will be available for items such as flex fuel, temp sensors, pressure sensors, thermocouples, etc.

    If I can get some answers I'll be sending him some cash

    Way back when, I was reading reviews and researching the MS3pro and thought I read that it can autotune the idle/part throttle stuff really well... I'm sure Matt will chime in here.

    Partial throttle stuff can be tricky. Some advice, turn off everything that effects fueling. Accelerate enrichment, ego correction, over run fuel cut, all off. Having those things on before your ve map is close will just mask things that will show up somewhere else.

    and make sure your injector data is correct

    What injectors will the 93 + meth guys be running ?
    I plan on keeping my 80#'er in there.

    So hopefully there will be others to share maps. Although my maps will blow up engines. Lots of them.

    Yeah, auto tune is for steady state lambda values. Its not for ignition timing, PID ICV control, accel/decel enrichments, ect.

    As dburt said turn the outside influences off and get the steady state fueling dialed in. From there you can tweak the transient corrections knowing the base map is on point.

    Just add a couple grand worth of meth control, failsafes, boost controllers and traction control and you basically have the same thing.

    Please email me the order details (support@diyautotune.com) and I'll have a look. Some PayPal "eCheck" payments take a couple days to clear.

    I'm checking with Kevin on exactly what he put on the expansion connector.

    Hey Matt, you will sell alot of these if you provide a simple way to make traction control work. Someone here can write a DIY on how to wire it in, they just need to have the inputs available on the expansion connector. I think with working traction control you will attract alot of the track day people and not just the turbo people. It will provide a huge value to the product.

    i agree.

    Having an extra VR input would make things very simple. Thats probably alot harder then it sounds.

    +1.

    Also if Matt would answer my questions he'd have some more money. I've seen three posts now by him with my questions falling on deaf ears

    It was just a bit of humour, they are clearly a solid company. Please don't get butt hurt.

    I'm 70% sold on the idea of going standalone myself but I need to get the car back together and running well before I'd consider it and the OBD2 version is not available yet. Traction control sounds promising. Hopefully the algorithm matures to the level that Racelogic TC did, I don't like the idea of going backwards.

    Yeah, I'm not too worried. I've been looking forward to it for some time. Unfortunately emission laws have been an obstacle. Its not going to be all that much different than what I do on a daily basis. Reading sensor values, diag, etc etc has been the norm for some time now. Looking forward to it.

    But the jokes about blowing it up won't stop till I follow through.

    I looked on the original post and I thought it was mentioned (but I didn't see it) that these PNP units will come with a base map. Will the base map have cold start enrichment and all that stuff setup? Will A/C work right off the bat (not sure if DME had control of this)?

    Basemap for a turbo car should be easily doable. Only changes really are to the lambda target map, ignition map, and the Req fuel value to match your displacement and injector size.

    Base ignition maps are easily available here. If Matt wants to make a turbo basemap to include I can send him a lambda target and base ignition map. If not we can just make them in here for people to use.

    If we are running a map based setup can the icv be deleted or will the ms use it to control idle?

    It still needs it to have a reliable idle I believe.
