If my Low Fuel trims are high, like at 139%, that means too much air is coming in and I need to add more fuel right? Well, if too much air was coming in, and not enough fuel was going in, wouldn't I have fuel cut?

The trims you read on your logger and telling you what the ECU is doing basically. 139% means the ECU is adding fuel past the target 100% because the O2 sensor is reading a lean condition, hence the need for more fuel. If you let the car sit there and idle and the trim stays at 139, you can start adding fuel 5% of a time and that number will slowly come down. The important thing is to give it time to change. It'll take a few minutes for it to drop then stop changing. If it's still high, drop another 5% and so on.

So, I add more fuel to the Fuel Trim Low by turning the "Idle" knob clockwise? Or how do I add more fuel to the Fuel Trim Low? Can I turn the "Base" knob counterclockwise to trick the ECU into thinking that there are smaller injectors in there, or should I just keep my "AUX" and "Base" knobs set for my 450's?

Thanx for the help 98spydert.....I'm this |---| close to getting this GM MAF-Translator setup dialed in correctly. Fuel Trim High and Fuel Trim Mid are right on 100%.

If you adjust with the AUX and BASE knobs, you'll adjust the entire fuel curve so if mid and high trims are right on now, you'll screw them up while adjusting the low if you use the BASE knob. I'm pretty sure it's the IDLE knob you're going to want to play with but I haven't touched a MAF-T since I bought DSMLink and calibrated mine so it would be best to just read the directions. If you bought it used and didn't get any directions, go to full throttle speed's site and download it.

I say we all take a little cruise up to Reno, gamble a couple bucks, have a good time and come back......that way we can put a couple miles on our cars, help each other tune our cars, take some bad ass pics with the scenery, and just have some good clean fun.

It would be great to have a bunch of people that can help me fine tune my MAF-Translator setup.

Who knows, one of us might win some money as well.


.....just a thought.

sounds like a plan
