MAFT Pro Clarification - speed density and other options explained

[Baron4406]

Wait a sec..........you mean if I buy this Maft Pro, then get a wideband.............I can simply put it "11.1" and that's the amount of tuning I'll need to do?? I'd really like to run Speed Density too. I have another question, does this mean I can run my Profec B in low boost and high boost - and not make adjustments?? Someone pinch me..........

Wait....just read the web page. Can't it log knock??

 

[BISHILVR]

Wow, I got it already, just two days after I ordered it.

 

[Baron4406]

Paging mike.........Paging Mike. You never answered my questions. I assume you can't log knock?? So I still need my data logger right?? No biggie.

Also I plan on using the boost solenoid, does that solenoid plug into the stock boost solenoid plug?? Or do I need to order the boost control harness.

Starting to look like I'm getting into the $600 range with my order...........

I honestly can't wait. My new water injection + my new wideband + MAFT Pro means a fun summer (until I break my motor/trans but that's a given )

BTW BISHILVR where did you order yours to get it that quick??

 

[FORMONTOYA]

I have DSMLink and am looking to get a wide band O2 to log with it. Will it effect the accuracy of the WB O2 if I split the wire to go to both DSMLink and the MAFT PRO?

I ordered right from mike at full throttle speed. The solenoid dont plug right into the stock boost solenoid plug, you can either buy the harness from full throttle speed or just wire it in yourself, they spec a GM solenoid. The maft pro does'nt log knock, it only logs the things that it controls.

 

[Baron4406]

Already bit the bullet and ordered from Extreme PSI, they are very local to me. Yea I pay sales tax but I like supporting local guys. I got everything to make my car run speed density / closed loop. My wideband O2 should be here soon too. This has got to be too good to be true, probably is but I'll be a guinea pig. I mean just dial in a 11.6 AFR and it holds that through the RPM range?? I mean my car with the EVO 16G ate my buddies 2003 C5 Corvette, this was at 19psi boost. With Water/Methanol injection I could probably hit 25lbs of boost. My fuel Injector DC's at 20psi were only 70%. I honestly can't wait. Bad thing tho in a week fishing season starts here and i won't have any free time, oh well.

Installed it, fought with it, car ran horribly, MAFT Pro wouldn't read AFR's. Its off the car now and I'll let you know if I get my $655 back. Horrible experience with this crap.

 

[The_Baldman]

Is the translator pro shipping, if so, I'm ordering it monday.

 

[Raph]

so i got ecu+ woot

 

[v8s_are_slow]

Aight, I leave my feedback as it stands at the moment. I'm not being biased towards it or any other product. Just my honest "opinion".

For starters, the instructions need a revision. I know they just came out with a new manual but it still lacks a lot. I have an AEM wideband and the one I have wasn't even listed. I chose #3 for the configuration in the section where you enter in what kind of wideband you're using but I was suppose to have chosen #7 (which wasn't listed in the instructions). I was fighting problems with my wideband for awhile to get it to read correctly and that was the problem. I'll say I wasn't too happy about that (it was reading lean but the fouled out plugs was showing the opposite). If it had been reading good but was running lean, my $15k setup would've been down the drain cause of them not adding in my wideband to the instructions. If you use a laptop to tune, there's really not much of anything covered to tell ya how to use the controls on it and I feel that definately needs to be done. Infact, I still don't know what 3/4 of the stuff is for on the program. As far as the quick setup page, well my advice is DON'T FOLLOW it 100% of the time!!! It's there to kinda quickly set it up but that's only if you have all the options THEY are using on that page. You'll know what I mean if you look at it. Just make sure you look at the main page and you'll be alright. To sum it up, the instruction manual really needs to be redone. I know they had to get something out quick though.

As far as features, well, yes it's easier to tune if you have the laptop. Click on the parameter ya wanna change, type in the number, save, and you're done. A lot better than clicking the buttons on the control box a million times to get the parameters where ya want them. You can't log knock with the laptop at the moment (but I've been told they're revising the program....but I haven't been told any expected release date) so it's kind of a pain to need the laptop AND my pda at the same time. In the bar graph mode, you can only "view" 4 parameters at a time although all are being recorded and can view them all at once if you select a different mode to view it in. Just not in the bar graph mode. Playback of the logs kinda sucks if you need to stop and view a specific area cause ya can't just click where you want on the log to see what the figure is (like pocketlogger does). You just have to kinda drag it to where you want it and the section to the far right of the screen is what is shown (hope ya'll understood that). But maybe the new version will be released soon.

They do incorporate a wide selection of sensors to be used with this thing which is nice. You can use an IAT or not, Map sensor or not, many different widebands to choose from, etc. etc. I even got rid of my stock O2 and use ONLY a wideband O2 with this thing. This is a very nice option to be able to go speed density without the costly expense of having to get the AEM EMS, etc. And if you don't have the Map sensor to run it in speed density, just hook it up in AFC or Translator mode until you do and then just switch it over with a few clicks of some buttons. The stock ecu helps to be able to tune it faster since the maps are already programmed into the ecu. I just ordered my chip from Dsmchips tonight and sure that'll make it even easier. If I wasn't going with Speed Density, I'd just recommend Dsmlink all the way and if Dsmlink were to go Speed Density I would've chosen it (because of the laptop program that they currently use). But since Dsmlink can't touch that option, I went with this instead. I even had an AEM EMS system but sold it to get this. I just didn't have the time to read over 250 something pages in one instruction manual, 50something in another one they had and years to figure that thing out and I wanna do my own tuning (everyone I spoke to said to have someone else tune it. Screw that!!!). I know I'm confident that I wouldn't have been as happy with the EMS as I am with this setup. Would I have been happier with Dsmlink? Well, they don't have speed density remember so they don't even count.

I will say that if you have everything hooked up right and select the configuration settings correctly (which is easy to screw up if you're not paying attention to what the hell you're doing), it'll run pretty good just on startup. I like being able to adjust the A/F's throughout the whole rpm band. And also has a boost controller built in if you get the bcs ya need. This thing DEFINATELY has a lotta potential to surpass Dsmlink and AEM as far as the ease of use and sales goes if they'd just tweak a few minor things.

Yes the responses seem a bit slow on the forums from the admin and there's not a whole lot of people replying but most people who purchase this thing is pretty much for speed density and of course there's not tons of people out there running in that mode. There's a few guys on there that have been more than helpful towards me otherwise I'd be lost without them.

My setup is fairly new but sure my car will totally haul ass with this unit once I get the chip and have it tuned. I managed to figure out how to get it all setup and I guess my ONLY real gripes about the product itself at the moment is the program used to tune it on the laptop (not being able to view/log knock, no slider bars like dsmlink, not knowing what most of the buttons are even for) and the instruction manual to clarify things a lil better so that I wouldn't have to ask so many questions and feel like a tard.

Incase ya'll wanna know, my setup consist of a 2.3 stroker, T-67 turbo, Comp 101400 cams, FFWD built head with 1mm oversized valves, etc. etc. and many other mods that go on and on. I'll post updates when I have them and any compliments about this product when I have them (which will be when updates are released). Hope this helps some of ya'll.

 

[BISHILVR]

I'm liking mine just fine too.

 

[denniegst]

what is Full Speed density? why go with Full Speed density?

 

[v8s_are_slow]

Here's a link that briefly explains it but in short, you totally remove the MAF from the system. Kinda like the old VPC systems back in the day....

I bought my Maft Pro somewhere 6 months ago, and already running it for about 2 months - IMO: I can not tell enything bad about this thing, futhermore - IMHO it is the best thing on the market at present time (if counting properties + price). After installation of speed density with Maft Pro my car didnt even felt any difference and worked great.
And it could be even much better if it could count knoks, but... anyway, it is upgradable, so may be it will can in future

 

[44pirate]

I'm still dialing mine in. I think I've incountered a boostleak. Will be checking that in the morning.
I like it alot.

 

[v8s_are_slow]

I hope no one misunderstood my lil review on it. I really like the product. It's a really good product for the money to get speed density. I just think there could be some improvements though and that's what I listed.

To log knock isn't easy. It will require it to be plugged into the ALDL connector and get the knock from the ECU. You have to have knock circuitry and other paramiters that pertain to the specific engine config and knock sensor to be able to just hook up a knock sensor to any unit and get correct output.

For Mike. As far as wideband selection goes it appears some are having issues chossing what they need to for their particuler WB. Maybe it would be easier to just update the program to do either a choice or input for low and high voltage being lean or rich and what AFR they are at 0v-5v. Then people can get that data from the company of their WB or their instruction manual for it and get it right hopefully the first time.

From the looks of it this unit is pretty nice. I used to be pretty interested in it but was waiting for its release for months. I eventually just went and built a MSnS instead. All features should work great and boost leaks shouldn't effect your AFR. Of course you still don't want them. I like every feature except for the timing control. With the timing control you are going to defet the timing retard from knock which could be dangerous.

 

[sickgsx-316]

All these knock questions. Correct me if I'm oversimplifying it but if one is going to take full advantage of the product and control timing which requires a keydriver chip, why not also take advantage of the option (through keydriver) to turn the stock boost gauge into a knock gauge...then...knock is covered.

 

[44pirate]

I still have my pocketlogger, so I log in conjuction with Tunerpro. Yeah I have the knock guage from Keydiver.

Well, that gauge isn't really all that accurate I'm sure. You really wanna trust that thing when it comes to the life of the motor???

 

[v8s_are_slow]

Well, if I can't trust it to tell me the correct boost, I just don't wanna be trusting it to tell me the correct knock counts. I'd prefer something else. No matter if it's accurate or not.

 

[oztofrdm]

Im not running the speed density but i do have the knock sensor gauge on my chip and once you get use to the way it reads out, it is quite accurate.

 

[sickgsx-316]

Well, if I can't trust it to tell me the correct boost, I just don't wanna be trusting it to tell me the correct knock counts. I'd prefer something else. No matter if it's accurate or not.

The only reason the stock boost gauge isnt accurate is because well...its on a DSM!! However...the conversion isnt done by mits...its done by keydriver who knows how to manipulate these ecus!

 

[Maglin]

The stock boost gauge isn't accurate because it is using a formula of mas air and rpm and maybe TPS can't remember to come up with a number for boost. Once you do anything to the car it won't be accurate. Mine would follow my boost gauge until I past 12 PSI almost perfectly.

Thing is it's electronic. And all the knock guage conversion is doing is taking the knock count and sending it to the gauge for a lack of better terms. Their is another formula for it and also a table so you can have low and high resolution if you so wanted on your knock gauge. Anyways. It's accurate if you know where the knock counts are on the stock gauge. Maybe would be a good idea to make a sticker to mask over the stock boost gauge and you could actually have a better represintation of knock.

 

[Turbo Talon DL]

How is this speed density for daily driven cars? Is the drivability ok? How is the gas mileage? How do you select the range of the three loads?
