Maftpro Help!, need support!

Car mod's

7MGTE engine rebuild .040
Walbro with 12v mod
FPR with vacuum at 28 Psi
RC 550cc Injectors
Q45TB
IC pipe 3”
AEM wide band


I instlla the Maft pro and upgrade the MaftPro software to Version to 4.8, then the Set up, but the option and display tags are different from the old version but I try to set up properly.

After the set up, I star the engine, but at Idle have problems L (I don’t drive the car) engine dies and the RPM’s are to low around 500 to 600. :aigo:

The MP is 90-93 with the engine off, when the engine is running is 30-33.

The AFR in the tuner pro is around 19 – 13, but in the AEM gauge in less that 18, because the display don’t show any number only ---. :cry:

I attach a ZIP with bin file of my setup and a record file with the engine running for your review.

I hope some can help me. :1zhelp:

Thank you all and best regards.

i will try to post my settings later.. but honestly i dont know.. I have issues to..but you can try diferant things.. diferant size TB... and in the tuneresponce area.. you need to play in there... main scall set to 0.00 ? maybe... thats were mine is... and no afterstart enrichment..

I hope you can help me, you said in other post the you idle is perfect right , in my case the A/F at idle is a crap, moves from 14.X to 15.X, bud every 8 sec (is a example) the A/F drop to 18 and then return to 14.X, in any RPM do the same thing 

In other words the A/F is not stable 

By the way, the ECU is free of any sensor problem.

The voltage in the TB is .53, if I adjust the TB screw and reduce close more the TB plate, the voltage reduce to .45 but the RPM’s decrese to 600.

The RPM’s at idle are from 700 to 800


I don’t know what parameter I need to modify to try too fix the problem.

TB size

Low Tuning
Remove the TH from the maft Pro to the ecu, and install a 2.2K resistor in the ECU
Remove the HAC to the ecu and maft.

Im at work now... i will try to get with you eather tonight or over weekend... and we can go over a few things and see if we can get it running better.. Im very very busy at moment... i have tons of things i have to take care of today...tonight and this weekend but i will do my best to see if i can help...
