Evo8 maf-t in 1g

Okay so here is the situation. I got another 1g eclipse that I am going to do the evo8 ecu swap in. Also i already have a evo8 maf-t that was given to me and a set of 560s of a evo8 but currently have 450s installed. My question is if the Evo8 maf-t will work with my 1g ecu for the time being while i wait to get my tactrix cable or will i have to wait to use the evo8 ecu? Also if it will work should i set Aux/base to 0% in maf mode or to +20% because of the formula given for the evo8 stock injectors (stock evo8 injectors/new injectors) - 100% or (560/450)-100%=20. Or does the maf-t run off the injector value from the computer in which case I would have to set it to 0% if i keep my 450s.
Thanks to all in advance

1) Wait for the EVO 8 ecu. If you don't it would be like running an EVO MAF on your 1G ecu and you would have to do much MAFT knob turning and logging to get it right.
2) You should be able to run the settings at 0% for your 450's as long as you rescale and retune for smaller injectors in the EVO ECU (recommended). If you don't rescale and retune, you will have to set the AUX/BASE to add fuel--which the MAFT has limited adjustment and a low ceiling and adjust the idle, mid, and WOT knobs too--basically using the unit as a S-AFC.
3) Isn't there a MAFT section in the forum.

Good Luck.

First thank you for the reply and yeah I noticed i posted in the wrong section after it was already too late. I just figured if the maf-t was stock set that base2 aux C= 0% is like having 560 injectors then if i set it base E aux A would be +20%. compensating for the formula (560/450)-100%=+20%. But if the translator does have a standard injector value of 560 and it pulls that value from the ecu then i would be able to set it to 0% and tune the idle mid and wot.

I guess my real question is if the translator has a set injector value or if it gets it from the ecu.

I already have Evo8 injectors to put in. I just need my question answered if the maf-t goes by the ecu stock injectors or evo8. Because if it is ecu then i could set base/aux to
-20% and tune from there. Sorry for being so repetitive.

Could you possibly post a link showing the details of how an evo ecu is made to work in a 1g DSM? Thanks

The adjustments on the MAFT don't correspond to any specific injector. The ECU is ultimately what decides the fueling and injector scaling. One car my be fine with 750cc injectors on one setting and another may be fine with 625cc injectors on that same setting. The list that is given is a guide at best.

The MAFT can shift the HZ curve left or right at different points (IDLE, MID, WOT) or across the whole range (AUX/BASE) in MAF mode.

I would start at 0% on the aux/base and click all the other knobs rich (your choice how far) and watch your WBO2. If you find out the all the knobs have to be set to richen up, the go back and set your AUX/BASE to +5% or whatever the max is and click the other knobs back 1 or 2 or zero (again your choice). Thats basically how you play around with the box and get everything in line. When you are close to a stockish curve, you go ahead and edit the ecu fuel tables and get it dialed in.

There is really no answer, but it is possible if you try it out. You just have to experiment. There may be others that have done what you want to do, but I am not one of them so I can speculate.

Watch the WBO2, and let off if you're too lean. Adjust as necessary. If you don't have that gauge, I wouldn't even fuss with anything until then.

Yeah I know the concept of how to tune the MAFT and I have a Uego trying to tune without it is ridiculous. I was just trying to figure out what the percentages where of. But i guess from what your saying the MAFT calculates and adds/subtracts the percentage based on the values from the ecu. But unless no one else chimes in I guess I will have to be the lab rat.

OK so i got the MAFT set up and installed the EVO8 injectors just to be safe. I set base/aux to 0% and car idled beautiful with all other values set to zero. Consistent 147-15.4 @ 800. So from my experiment I have come to the conclusion that the EVO8 MAFT is preset to the 560 stock injectors.
