Ya man, that's really big news. Imagine the possibilities...:) :woot: :)

[RaptorRacing]

Woooof'nhooo....great news spankMastah...thanks for the update.

[swank]

Wow, I ordered one yesterday without even knowing about this update.

[Tire Shredder]

holy shit!!! I just read that it can/will be compatible with the 7MGE aswell!!!!
speed density, wide band, timing controlled cammed 7m.....mmmmm *passes out, starts choking on on drool*

[Tire Shredder]

NA guys rejoice! the next SW rev. of the MAFT pro will have the NA factors in it....i suppose this would apply to other toyo flapper AFMs as well...

ok, I'm sold....that's wicked. all the goodies of a standalone, reliability of the TCCS still intact and less headaches. This could possibly be a future solution for 5m/6mers aswell to get rid of that AFM and all that good stuff....this is a huge development for our community I think

[KurtW85]

yes! im stoked about the 5m statement above...that would be sweet...MAFT PRO here i come

[BillyM]

...does it control the injectors/ignitor directly?

...if not, I'm going to have to poop on you're guys's parade a little bit. Until we get someone in here who says this does infact work with the 5m, I'm going to have to say NAY on the whole timing control setup here, especially those with AFM's. I mean, really... All I think their "flapper afm compatibility" statment means to me, is that they can correct the voltage curve of the stocker... kinda like an SAFC...

I'm not convinced, sorry kids.

^^^^^
I'm afraid that's a no no. No direct injector control here, after all there must be something left for the standalone units huh? ;)

[Tire Shredder]

old thread, but I thought I would update it since somebody actually made a 7m-ge installation write-up and has it running on his car. soooo...it works on flapper style AFMs. I don't know the specific differences between the 5m and 7m afms, if it actually uses the same voltage scaling or not, but it gives 5m owners some hope.

hello supra guys

welcome supra noob. please direct your greetings to the Introductions thread. http://forums.celicasupra.com/forumdisplay.php?f=38 You can meet many members accordingly at that location.

Thanks!

Who are you to call someone a newb? thats funny. Would be sweet if this works with 5m. Who has cash to try? Who wants to take one for the team? i would but im about 2k behind with my project. gotta be someone with cash to play.

From my experience MAFT Pro is better suited to a turbo application that is pushing higher than stock boost. There most likely will be little to no improvement with a N/A 5/6M. Timing control is not very well developed for the 7MGTEs let alone the N/A 5/6/7Ms.

even at stock boost with some tunning you can feel the difference.


im sure once a few emmebers start playing with it alot will be opened up for n/a's


for me this is what i noticed.

faster throttle response,
motor reved faster both free rev, and under load in gear.
cleans up the engine bay when used with speed density.
ability to data log, timming, afr, intake air temp, exhaust temp (not sure but i know you can log 2 aux channels im sure one can be programed for a egt sensor) boost pressure, rpm,


i pesonaly was sold when i could remove the afm, to me i was swaping from n/a to turbo and was picking up all the parts along the way, when i heard i could pick up a piggy back fuel computer, save on not having to purchase an afm, or a seperate boost controler, and it did all the functions of a sfac, and had a larger fuel map,


fuel cut being there is a huge plus! even though a pain in the ass, it saves your rig when you are stupid...
and for those smart enough or dangerous enough you can still clamp it and tune past it allowing your self to run the ragged edge ..


timming control would be a big plus, but still under development.

Stock runs rich when in boost. If you lean it out a slight bit you will notice a difference. You are correct.

At the given rate this will be in a few years as there is only one person I know of that is running a MAFT Pro with a 7MGE. He says it has been successful but isn't telling me all of the details.

And from you description I assume you never ran it on an N/A and only ran it on a turbo. If you are just starting a turbo swap it may be worth it to get the MAFT Pro from a cost stand point you may bee able to get a MAFT Pro set up for cheaper than the stock GTE parts you need to get.

All I was trying to get across is if you are an N/A guy you may want to wait. Development for the 7MGTE is much much more advanced than development for the N/A guys. For the 7MGTE, its pretty much been cookbooked. Follow a proven setup and you are good to go.

For a disclaimer: Some of my problems with it could be do to running 7M electronics on a 6M.

[pimptrizkit]

yep, other then when i ran my car home with a intercooler pipe blown off, i have them set up on turbo car's.

i can see your point of veiw aswell,

to me i just got the most bang for buck when i was looking into upgrading.

With a stock 5/6m for sure, but theres no much point in messing around with fuel control/standalone with a stockish motor. My air fuel #s are so messed from all my bolt on mods, even without lossing the restriction of the flapper afm theres big power improvements to be made. I need to look at the wiring schemetics in way more detail, but you'd think it wouldn't be that much harder to get the Maft Pro working with a 5m ecu. I'd think it would be even better suited to it actually as we have no ACIS system to complicate tuning.

As for SD, its worthwhile if ITBs is your end goal, otherwise I'd just stick with a hotwire MAF. I really don't like the idea of my tune changing with elevation, I like to drive all over the continent. A MAF should be much better in that respect and the extra restriction is truely neglible when you consider your coming from a flapper style afm (its neglible either way for non turbos).

What do you think Darrow, do you really need a 7mge ecu to get this going? For sure theres the injector sizing issue, but if a set of 250cc injectors could idle right on a 5m ecu then theres not much incentive to go to a 7mge ecu. I'm really not too concerned about the lack of timing control, the timing maps really shouldn't be that radically different if your staying NA.

[Darrow]

7MGE has been done before 5MGE has not, but If you look at the ECU pinouts for a 5M and 7M they are not that much different. The 7M compensates for Lights and Defog and has an extra injector pin and the 5M has a spot for oil pressure detection. The rest of the pins are pretty much the same. I don't see a reason why a 5M ecu would not work.
The thing that I would be worried about is the setting in the MAFT Pro. That might be because I have not look into it that much. The documentation is pretty lacking. The message board is the biggest help.
