Maft Pro initial start up lean!

[rs4rush]

Were talking 18:1. So today Justin and I got everything done and set up. Followed the quick setup instructions given. I tried everything to my knowledge and still came up empty handed. On initial start up I am around 14:1 which is fine with me then a few seconds later it jumps to 15:1 then on and on to 18:1.

Is their a master reset?

I think it might have been used with a different car...

Thanks in advance! :bigthumb:

Here is a video to show you what its doing!





Also tried Justin's Maft pro and same thing... So now I am thinking it has somthing to do with the ecu...? Any suggestions?

There's a note at the end of the Maftpro User Manual that explains how to do a reset. I suggest you set your maftpro to use VE Table #2 before and after doing this. The base tune on that table is a closer fit for our cars than Table #1.

I will give that a try.

You may want to re-calibrate your WB sensor too. I don't think it would be *that* far off, but stranger things have happened.

are both of your grounds for the wideband and maft pro grounded at the same point?
i recall hearing that makes a difference.

Your aux 1 voltage is flat lining at 0 volts so you know its pulling as much gas as it can.

Mine did this for a while but just playing with the mainscale according to fuel pressure and injector size made a difference. That and tweaking the lower idle values on the VE table.

your sure PTT is off?
