MAFT Setup

[suprasport91]

First of all i am going to be installing my maft that has been sitting around for a couple months

I recently replaced my headgasket and a bunch of other small stuff, and i am finnaly finished putting most of it together, i however want to install my maft basic gen 1 and 3.5 gm sensor

I found some usefull information on the installation of the unit, that is not the problem, however, basic tuning is

To have a very primitive yet safe tune, can i just follow the initial setup and select the 3.5 gm sensor and then leave the system alone?

I will be running 440's with the 3.5 sensor, if you need more information just post as i am sure there is more to it

anybody? sorry if this seems like a stupid question or what not, but i just need the car the run untill i can go to a dyno

you can pretty much just plug it in and set it per the instructions.

you might want to monitor the Vf signal to ensure you aren't too far off....

I assume you don't have AFR monitoring capability? I would take it easy on the boost until you know what your AFR looks like. IMO, the 3.5" MAF is too big for a mild setup but I can't say for sure. I think you would run a little lean with the 3.5/440 combo. If that happens when you tune you can set the MAF-T to a smaller injector and it will increase the injector duty cycle.

If i had the 3" would it be easier to just set it per the instructions? I dont know why i have the 3.5" seems i ordered it instead of the 3", must have been on crack

Its a Pretty Easy setup and yes, It would be easier to use a 3" GM sensor instead of a 3.5". When I ran mine with the 440s, I left everything at 0....ie

Idle "0"
Mid "0"
WOT "0"
Just ensure that the Mode Switch is set for the Appropriate sensor
Set the Base at 2 for 440cc Injector setting
And if you want to Disable fuel cut, Set the AUX to C.

I ran this setup for quite some time. It would be very helpful if you had a wideband so If you need to Adjust the Idle 5% then you can see where your A/F ratio is....

It works great but again, I think a 3.5" Sensor is a Overkill..... Try it though, It might work but you might have to make some Percentage Adjustments to Compensate. If you need any help with it, Send me a PM with your Number and I will be Happy to give you a Buzz
