MAFT settings questions
Ok, So Im about to put Evo3 510cc injectors on my 4g64 motor 240cc stock injectors which has OBD1 ECU/1g/, but I get all kinds of information about what settings I should dial for BASE and AUX. Its 1st gen MAFT ver. 1.6. I researched it and got lots of info on it and from what I found out I need to compensate 53% with the MAFT.
Formula: (1 - stock size inj. / new size inj)*100 = (1-240/510)*100 = 53%
Here's the confusion:

If you follow the link^ and cross match 53% youll see settings BASE = A; AUX = F
Another one:

If you follow the link above theres a tuning table for MAFT ver 1.37 and above, and youll see the settings BASE = 8; AUX = 0
One more:

If you follow the link youll see instructions for ver 1.3 which puts the BASE setting between A and B for 53% lean out.

So, if someone is using MAFT, please help. I need to know what settings are correct. Just keep in mind that OBD1 fuel trims are leveled at 100%,and they are not like OBD2 trims leveled at 0%

with a maft, you will NEVER get it perfect.
ever.
with that said. you aren't going to hurt anything if you get it wrong.
so just slap it on, and try a setting, watch your wideband, make adjustments.
done.
-
I wished we could log the fuel trims, but damn that OBD1.5
-
Great tool non the less.. I'm running it in my 8g with no problems, but i'm also simply retranslating mas signal so i can do blowthrough

-
the manual that comes with the MAF-T should have a look-up table for whatever injectors you are running, I would start there and trim the rest with something more versatile like S-AFC2
Worked miracles for me.
However my engine is a 6A12 which the manual does not cover, I simply based the tuning on the fact that the Galant VR4 MAF is the identical part to a 2G Eclipse and turned the settings to match. If I change my injectors I will have trouble getting it right again.
-
how did you end up setting this up just curious.. with the new MAFT Pro i can set my desired a/f ratios and be done with it
-
IDLE 14.7
IDLE to 3000/Cruise at 65mph/ - 14.7-15.5
youre gonna have that 14b spooled by 2500
3000 and up, youre gonna have to set it for your car, but try to richen it down gradually to 11/WOT/
I know my 3/4WOT pulls are around 12 and it goes down more. If I do WOT with AFRs in the 13s I get knock
-
ok thats good to get some numbers to go off off.. i have a b16g as well that im going to rebuild maybe as a 20 or as a b16g again.. i know it will spool quick. when i get it all in im gonna hopefully use the shops dyno for some tuning and adjust the cruise off of street runs and get some numbers as well
i really dont want to lean out thats my only real fear
-
so at wot w/turbo you want leaner top end?
-
-
that makes sense then tought it was the other way around
-
these cars have a tendency of running really rich up top.. i was helping a buddy tune a 1G a while back and the ratio went to 11s no matter how much fuel we tried to pull and you could just feel it bog out
i really dont want to lean out and i feel with the maft pro ill be able to stay away from that situation
-
If you running rich and cant tune it out then you have after maf leak. Dont ask me how I know
-
this was on a 1g with a 2g maf..
i dont believe im going to have any leaks.. everything is new including the maf
mko are you going to upgrade to gen 2 or pro so you can get rid of the safc or what are your thoughts on your current setup
-
let me know that you think of the pro, I looked at one and just wondered if its really all that much better
-
its a boost controller has many tuning capabilites and can use it in 3 different modes.. my choice is between pro and gen 2 currently
-
Yeah, Ill get gen2 eventually, but I needz a job first. I like the MAFT+ SAFC, but i need some more stealthy and of course the ability to track wideband makes the gen2 much better than SAFC.
-
so the gen 2 will replace the traditional wideband gauge and just gets wired in to an O2 sensor?
-
Yeah, you dont need the gauge, but you still need the wideband controller with the necessary port.
