Tuning gm mas

[1990talondsm]

I have a Gm MAS and the Translaotr on a 1990 talon TSI. I know there is a little bit of tunning that you can do with this item. I have a big 16g and stock 550 injectors. I am getting a walbro 255 and a fuel pressure regulator so I can up the boost. The car came with 450 injectors. I was wondering if anyone knew how to tune the GM MAS with translator.

All it does really is compensate for the injectors.... And help with idle on the low trim.....

It can be tuned a little, but mine ran the best with the knobs for mid and high zero'd out...

Do you have an afc, it makes it alittle easier.. And 550's are stock....in a Toyota Supra.

Do you have a logger or wideband? The maft is easy to tune. If you need more fuel turn the knob to the right. Less to the left. You have 3 knobs to tune with. Low, mid, and high... Use the logger it will get you close.

Regardless, the Translator isnt a newbie tuning tool. Especially if you have no wideband, egt or logger.

I have a palm pilet that I can read engine vitals and codes but no wide band. What do I need to look for on the Palm pilot

Well I would say Fuel Trims. I always just used my WB so I am not 100% sure. Just try and get the fuel trims as close to 0 as you can.
