maftpro is working

[IJ.]

the fact that it can take wideband input and maintain a set A/F ratio is extremely cool.

:currently saving up:

Agreed 100%!

I was excited with the Wideband on my new Wolf till I worked out it's just a display and can't actually do anything to the tune based on the WB 02!

It can do closed loop on the NB 02 but that only works in a narrow range at cruise!

whoa....the wolf can't do closed loop all the time?!?!? that sux....

 

[IJ.]

You can set it's range but it can only make small adjustments!

Guess it's a non issue now as the Gas system is totally gone from my car and it's now LPG only!

 

[drjonez]

heh, i suppose that is a fairly moot point now...

 

[IJ.]

LOL yep <sitting here smiling at this>

(just saved me a bucketOcash converting to the MAFT+extras to make it tune itself)

 

[lanternman]

Awwwwww, but I just changed to the lex, 550's and safc. Oh well, I guess I'll just have to wait till next year.

 

[drjonez]

sell that SAFC and you're halfway there!

 

[IJ.]

I run a seperate NB controller/injector for the LPG for acc/cruise as well.

If I was staying Gas I'd jump on this setup for sure!

 

[Fuzz420]

that is a dang good question, i'll look into it. off the top of my head i don't think it can handle flap-style AFMs, but i certainly could be wrong.

Thanks please find out a definate answer.If it turns out it can handle the flapper system that would open up many more possibilties.

 

[lagged]

so, this completely solves the problem of tuning during openloop operation that you would have otherwise have had to go standalone to get around?

 

[tte]

I am very interested in this setup.
Why dont someone compile this info into a list which would be easier for those who are not familiar with MAFT-PRO?...example..

MAFT-PRO Unit with harness - $399 +$24

For Speed density:
MAFT-PRO unit with harness + whatever sensors.


And list other options...

Would be a great help...

Cheers,
Roy

why would you go blow through? for $500 you could go MAP and never have AFM problems again...that's the whole point of the MAFTpro.

that's what I mean, MAP in the spot of the 3000 pipe. I've heard people call that blow through MAP, maybe I'm a little confused.
The internet isn't an infallible resource?

Might as well throw this out since many of us own the ZT2 WB which I believe is not on a linear scale. Will the A/F on the fly tuning work with this or must the input to the unit be linear?

Linear?

It could be logarythmicl but if i recall the MAFTPro can have the voltage input for afrs. So put that in and regardless if it is exponential, linear, logarithmic. It still should read the appropiate AFR's reading.

 

[Blue87T(Dan)]

I might have used the wrong term but I read that the E-Man Ultimate will not do auto AF tuning with the ZT but will with other makes.

That is the jist of the question.

 

[supralover2000]

Glad to see all the inquiries about this product! I vote for this to become a sticky once we can compile a solid list of info and pictures. Doc Jonze, Keep the info and development coming. And to Bob (fullthrottle) Thanks for bringing your knowledge to the MKIII community.
P.s. My unit arrived at Bailey engineering today for the revision.

 

[isnms]

Dan; good question. I have the zt-2 also. I didn't know some systems didn't work with it an some did. I'll be watching to see if this is an issue.

I was looking at the wiring diagram. Am I seeing it right? Are none of the wires cut, just tapped?
From the maftpro web site

 

[Blue87T(Dan)]

I am thinking that logic might needed to be built in for specific WB units since the signal is coming out of the unit rather than directly from the WB02 sensor. Otherwise why would anyone buy the unit if you could just measure voltage from the WB02 sensor.

The first .pdf you posted might confirm that.

On the fly tuning via a wideband would/should make sure you get maximum power to the ground at the dyno or the track without having to make adjustments. Dial it into 11.9A/F at X%tp or X amount of boost and let the MaftPro do the rest.

I find this interesting and am quite interested to see where it goes, but since my car is good for another month and a half or so before it goes away for the winter I won't doing anything until spring.

The good news is that if you have a lex afm and and an safc, after selling those parts, the net cost would be less than 300.00 to make the transition(sp).

Hopefully, for you, I, and other ZT owners, we can get a definitive answer on my question.

Malloynx, if we are jacking your thread, maybe you can move some of it to a new one since you are a mod.

Could this be run with 7MGE electronics?

 

[Idealsupra]

why?

does the MAP ECU control boost?

does the MAP ECU correct for temperature?

does the MAP ECU have a keypad to make quick changes with?

does the MAP ECU have wideband input and control of mixture?

the answer is no on all accounts....

personally i wouldnt want my air/fuel device tuning boost also...unless its standalone which all these piggybacks obviously arent. for some reason it bothers me.

the map ecu does have a IAT sensor that has to be purchased to run without the afm...and uses that in tuning purposes.

the map ecu doesnt have a little keypad but frankly i like that...i like that i can unplug a cable and not have a box sitting there all the time...and plugging a laptop in is easy as hell. not to mention aside from tuning you shouldnt have to mess with it every day all day anyways.

and finally the map ecu DOES use wideband input and log it and will help build maps based on it.... you just need to make the sure the WB is compatable with it...

so like i said before....i still vote mapecu...however obviously the product development is AWESOME...the more options the better IMO so i commend you for helping the development and its a great piece.
