MAFT question.

[suprafredde]

Hi.

We were a few guys from sweden that ordered the MAFTs.
A friend hooked his up and the leds did not light up at all, faulty unit.
So today I decided to check my unit. Hooked up 12V and ground.
Also extended the MAF cables to around the stock afm, then plugged the MAF in its connector.
Set the dips 1 and 2 for my 3.5" MAF. 3 and 4 is in the off position.

Turned on the ignition and the red led lit first then also the green and after 2 secs they turned off. Ignition off and I get a short blink from the red led.

After this I thought if I removed the MAF I would get a trouble code.
2 red blinks I think. Nothing, just the initial blinking as above...

Does the unit have to have IG pulses in order to check the codes, something else?

Sounds like it is operating correctly - mine does the same when the ignition is turned on. I did manage to get some trouble codes from mine at one time, but I had everything hooked up as described here:

Thx Grim, that was exactly what I wanted to hear! :icon_bigg

Im a chicken so Im going draw thru to avoid contamination of the wires since the stock pcv is still on.

Another q, safcII before or after the translation box?
What happened with the FC function not working properly?

Between the ECU and the MAFT. The MAFT sends information to the SAFC as if it were coming from a real AFM.

I still haven't gotten FC to work - I haven't gone back and worked with it recently though, so chances are it's entirely my fault. I don't suggest using that feature in any case, I'd rather tune it higher than remove it entirely.

for some reason I couldn't get mine to work
