Default Launch and Traction control on an NA

Hi, I'm new here, but I've been reading a lot in the forum about the Adaptronic and I have to say I'm really interested. However I have some questions first.

I'm looking at a spreadsheet made by Travis comparing Adaptronic with Hydra and MSPnP and it says that launch control is not plug and play for 89-95 models. I'm a little confused by what that means. Can it have a rev limiter for when the clutch is pressed and the throttle full? Kinda like this box:

Wide Open Throttle Control Unit

Quote:
What is 2-Step Launch Control?

2-Step Launch Control allows you to program a desired launch RPM, then if you press the clutch and subsequently floor the gas, the engine will rev up and the WOT Box will kick in to hold your desired RPM. It will cut fuel and spark to accomplish this. The turbo will also develop boost. you can use this feature at the track for a more consistent and more powerful launch in boost! Visit our See It In Action page to see it at work!
I also remember Travis said he was working on a kit for Traction control on NA models since they don't have the wheel sensors, however I couldn't find if that had been released or not.

Finally I couldn't find anywhere if you could have more than one map loaded in the ECU and change them on the fly with a switch. Basically one for when saving gas in city traffic, a sportier one, a race setup, etc. I think you can with the Megasquirt, with some mods and something called MPI Tunning can store 2 maps. That's a feature I'm really after.

Do you ever have something useful to add or are all 1,470 posts this useless?

Hey you know that flap of skin between your legs? yeah it's called a dick, I guess some know how to use it... obviously you don't.... on a more realistic note when you join something such as an internet forum full of wondrous things that you strive to know about, you become submissive and by submissive I mean the kind of submission I put your mom in every night with my **** after she tucks you in. look gay I'm not here to be your little "buddy" I saved a mod, (who works hard enough on their free time), the time and effort to say the same thing because that's what someone would've said 2 secs after I posted. If you can't read either that's your problem and about that flap of skin of yours...... lemme know when you grow some and contribute to this forum.....
OP you can also use the search button there are loads of threads here with tons of info just put in a lil effort you'll find what you need. GL

What more do you need to know about me? Every relevant piece of info for this discussion is in my profile (and was mentioned in my post). I thought I'd rather hit 2 birds with one stone and get the introduction out of the way here, instead of wasting everyone's time with a thread just for that. If that's frawned upon here I apologize.

I've obviously already searched this and other forums, I've read extensively every thread on the Adaptronic I could find and a lot about the MSPnP as well, but I haven't found a straight answer to my questions. Hence I thought I'd asked some of the more knowledgable members here.

For some of the stuff I want more recent information that what can be found here (TC and LC). The Adaptronic web site, says it's supported, but the spreadsheet made by Travis sort of contradicts that. Plus, how does TC work if you don't have ABS? Do they sell the sensors or do I have to buy them somewhere else?

Maybe I'm using the wrong terms in my search. English is not my first language after all. Maybe switching between maps on the fly has a specific name I haven't been able to find. If you have anything useful to contribute I'd appreciate it.

YOU can't read. you own an MS and this is the adaptronic forum.

anyway, to answer gambit's questions:

the launch control limitations for the earlier cars may have something to do with the non-variable TPS, but I'm not sure.

I've heard nothing on traction control for any years without ABS sensors. you could fairly easily make your own with the right sensor and hub-mounted trigger wheel.

as for maps, you CAN have multiple fuel and spark maps loaded, but there's no real point for a typical application unless you're changing fuels. if you want to calm the car down for normal driving, just drop the boost pressure or switch out the boost controller to run wastegate pressure.

why: a properly tuned map should address all aspects of driving styles. for light load, you can tune a leaner AFR so you dont waste gas. for high boost, you tune those cells to be more rich. etc. etc. the rest should be consistent between driving styles too.

i would love to see why as well. v-tps is easy to get

and the map switching would be nice for people who run different fuels. i would definately like that since i drive to the track and sometimes its a long haul where i would love to not have to run meth or that type of thing. so i can just lower the boost via ecu boost control and pull some timing up top.

ah but different fuels affect more than just steady state fuel requirements. the adaptronic uses absolute values for enrichments. they all would be wrong. for a different stoichiometric value.

better to just load a whole new map for a new fuel.

Y8s/Shlammed, thanks for actually trying to help answer the question.

Crazy, unless your car originally has ABS, there'd be a fair bit of work involved installing the sensors. On my '97 (w/o ABS) the bosses for the sensors are there but not finished so some machine work on the uprights would be needed to use stock parts. It would certainly be worthwhile to do from what I've seen of how useful 1st/2nd gear are in higher hp Miatas.

I had read about multiple maps not really being neccessary, since if you're just driving around town the turbo you could set it to near stock and then gain power at high rpms. I was just wondering why some sports cars have those switches from the factory (like the GT-R for example), is it just for show? or does it serve some purpose?

Also I was thinking that it could actually change the rev limiter. I don't want the valet getting my car up to 6.000 rpm even if it's stock or if I let my gf drive for example.

Most modern cars that have a "Sport" mode change more than just engine characteristics... they also mess with stability control/traction control/torque bias (AWD cars)/suspension settings.

I'm inclined to agree with Y8s that multiple maps aren't necessary but you bring up a good point, a "valet" mode could be useful if it's something you'd use enough to be worth the effort.

there's no specific valet mode on the adaptronic, but maybe you could set up the launch control to be a secondary rev limit.

Yes, some of us do know how to use that flap between our legs, but just because we do does not mean we have to be one.

Also the mods do work hard but you don't have to be a dick while helping someone else.

I once heard that people who talk about how big or how well they know how to use their dick are the ones who either are not endowed or they can't please a wattermelon. Don't take this as an atack as I am shure you will, but just something I was told buy someone whom I respect. Also it sounds like you have mommy issues.

Have a great day,
Jared
