Message I recently upgraded from a single POP to dual intake set up with dual MAFS and Selin Translator. Since my ECU (ZTUNER) is set up for Single POP, 555inj, 5spd I set the Selin to ADD. I started the car, it started well, and revved to usual 1500 RPM when cold, but once it dropped to below 1100RPM the car died almost immediately. Tried to restart, and it stumbles a bit, will not rev, and does not idle.

I put a Multimeter on both MAFS and got resistance readings from both on every pin. Re-installed my Single POP with each MAFS (one at a time obviously) and car runs perfectly fine and idles perfectly with either MAFS.

Reinstalled the dual pop again, and same result...car wont idle or even start at this point...just stumbles a few times. Tried switching the Selin to AVG and it acts the same way as in ADD mode.

Could this be an ECU Problem? Selin unit defective? Any help would be a great help.
